Downgrade 4.3.5 to 4.3.3 without SHSH Blobs to get Untethered Jailbreak for iPhone 4, 3GS, iPod Touch 4G, 3G, iPad

by on August 24, 2011

Redsn0w

In the past we have provided complete procedure to downgrade firmware of iPhone 4, 3GS, iPod touch 4G, 3G, iPad 2 (wifi) and iPad 1 using saved SHSH files from TinyUmbrella. We also mentioned in one of our post that Apple is still signing  4.3.1 for iPhone 3GS therefore downgrade is possible. However it may be possible that you have forgot to get SHSH blobs on the previous versions of your iPhone 4, iPad or iPod Touch and cannot downgrade but recently Mokhles Hussien at Limera1n has come up with a procedure to downgrade to iOS 4.3.3 (provides untethered Jailbreak) from iOS 4.3.5. What’s Needed

 Procedure

  1. Download Restore Files from the link mentioned above
  2. Browse following directory C:\Windows\System32\drivers\etc , and replace the “HOST” file with the downloaded file under the “Restore Files” folder
  3. Run Redsn0w and jailbreak the device using the tutorial here but you have to point to iOS 4.3.3 rather than iOS 4.3.4 or iOS 4.3.5.
  4. After the procedure is complete the iPhone will stuck on recovery mode.
  5. Open Tinyumbrella (present in “Restore Files” folder), right click on your iDevice name on the left pane then press on Start Tss Server.
  6. Open iTunes and restore your iDevice with iOS 4.3.3 firmware using (Shift + Restore).
  7. You will get error 1013, now use Fixrecovery (present in “Restore Files” folder).
  8. Open iFaith (present in “Restore Files” folder) and Save shsh blobs.
  9. Open sn0wbreeze (present in “Restore Files” folder) to create custom iOS 4.3.3 firmware and restore it using iTunes (Shift + Restore).
  10. And you are done downgrading your firmware.

If you are getting iTunes Errors see procedure for removal Error 3194, 3164, Error 3014, 3004, 3002 and Error 1604,1603, 1602, 1601, 1600 0r 29.
Note: This procedure has ony been tested for iPhone 3GS by Rayant410 and few other but its worth giving a try if you are stuck with tethered Jailbreak. Please leave your feedback in comments after using this procedure.
Update 27th August 2011: Our user Rayant410 and few others at Koolmobile have successfully downgraded their iPhone 3GS from 4.3.5 to 4.3.3. You can read the thread in comments below.

Update 2nd September 2011: It has been confirmed working on iPhone 4 by Redhairpro and iPad Original. Please read the comments below for details.

Update 7th September 2011: Koolmobile user Jad has successfully downgraded iPhone 4  please read the comments below for details and suggested a work around (thanks Jad) which is as fols,

Done…!! :) 
For whom they couldn’t continue the point 8, do the following:
1- Go to C:\Windows\System32\drivers\etc, cut hosts file and paste it on your desktop, delete all previous “hosts” and paste #74.208.10.249 gs.apple.com instead to be as the following;# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
#74.208.10.249 gs.apple.comPoints 3,4,5,6 & 7 are the same as mentioned in the topic above. 8- Start iFaith while your iDevice in the recovery mode NOT in the DFU mode. 
** Try many times if it stuck on Apple Logo step… USE iREB to enter DFU mode. I downgraded my iPhone4 from 4.3.5 to 4.3.3…. SO LUCKY.. :)
Update 23rd September 2011: One of out reader Jimdaza has successfully downgraded iPad 1 using the procedure above. However for Step 8 use iFaith 1.2.1 (link) rather than the one included in downloaded Rar.
If you need further help in using  Jailbreak software you might like to see Redsn0w Jailbreak  & JailbreakMe or to Jailbreak while preserving your baseband (software unlock) see TinyUmbrella,  SnowBreeze &  PwnageTool.

        I Confirm you it doesn’t work on an iPhone 4 16go in 4.3.5 without shsh 4.3.3
        i get errors 20 and 1600 like a lot of people ;)

        hvdcgkl from frenchiphone

        • B52psi

          I would like to share, that I had solve error 20 by doing the following:
          -that error should appear when the screen of iphone was “connect to Itune”, press home button and switch button for around 7 second then release switch and keep home, untill it connects back to itune, now restore by pressing shift + restore in itune, but you will face error 1600 and error 1601, solution was through IREB in DFU mode,

          Then I got loop stuck in Ifaith at Apple logo by detecting IOS and sequence issue on iphone screen , beside my itune is the latest version, but never passed this, and my Iphone 4 stuck in DFU mode and nothing helped to kick it out from DFU mode, tried tinyumbrella.

          Any help would be appreciated!

          Many thanks.

          • Bestcch

            B52psi… i think u already downgrade to 4.3.3 but is tethered… u need to use redsnow and boot it… i have same problem and is tethered.. boot with redsnow but.. eventually it will goes into DFU mode time to time… still had no idea to solve this problem

          • B52psi

            Thanks Bestcch, but whats the need of 4.3.3 downgrading if it will be tethered! Beside in Ifaith when it is in loop stuck it shows on the iphone screen 4.3.3, so I knew that the phone is on 4.3.3 FW but not completed! I think the above tutorial needs more attention!
            Thanks again

          • Redhairpro

            Test on iPhone4. IT WORKS PERFECTLY!!! THANK U!!

          • B52psi

            Dear Redhairpro,

            you only followed the above procedure to downgrade or you did extra steps?

            Thanks

          • Chris666uk1

            Here method for you:
            1. Download TinyUmbrella Fix Recovery.
            2. Download zlib1.dll.
            3. Fixing iphone 3gs open fixrecovery43. Put ur iphone in DFU Mode and let the command window do everything.
            4. If u did everything correctly ur iphone 3g/gs should be in recovery mode “Its normal”.
            5. use iREB RC4.
            6. Restore to 4.1 then get error “1015″ download Tinyumbrella to kick out of recovery mode.
            7. Finally just jailbreak ur iphone and unlock if u want.

            Try FixRecovery to get out of Recovery mode

          • B52psi

            Dear Koolmobile, if you notice in step 6 it indicates to restore, and that restore is done in DFU mode, after restoring i got the error 1013, then to move to step 7 which means to use fixrecovery, after double clicking fixrecovery, itune and the error 1013 indicator will close automatically, and my phone kept in DFU mode, so the fixrecovery will not kick my iphone from DFU mode!

            Thanks for helping, but I think something wrong with ifaith.

          • Choy

            how many minutes it takes when i use ifaith?im stuck in detecting ios, pls help.=(

  • Roy

    does this work with iPad2 (Wifi) with firmware 4.3.5 OTB ?

    • Anonymous

      yes its compatible for iPad 2 Wifi as well but not tested yet

      • Anon

        redsno0w doesn’t accept the ipsw for iPad2 Wifi

        • Nigger

          agreed, won’t accept ipad2 ipsw’s

          • Anon

            its because you can’t use redsn0w to jailbreak 4.3.5 on ipad2…or else I wouldn’t be trying to downgrade, I would just do tethered jailbreak

          • Sledge5hammer

            Redsnow doesn’t accept 4.3.3 IPSW files…..which Redsnow do I use? None I have found does work.

          • Phil

            for iPhone 4, use redsn0w_win_0.9.8b5. this is for tethered boot. i think redsn0w_win_0.9.8b6 is for iOS 5. good luck!

    I cannot reach to this step – “Open iFaith (present in “Restore Files” folder) and Save shsh blobs.” It is not allowing me to save the SHSH blobs.
    I had accidentally upgraded my iphone 4 to 4.3.5 without saving the shsh blobs and now i want to switch back to 4.3.3. PLEASE HELP

      Yes SHSH Blobs are unique and using this procedure you can save SHSH blobs for your iDevice on iOS 4.3.3 and restore iOS 4.3.3

          • renoster

            Yip, same here – ran the steps a few times and now sit with a tethered jailbroken IP4 on 4.3.3

          • Test

            I am on tethered jail broken 4.3.5 on 3gs. Will be very helpful if someone who had successfully done this post the modified instructions. As I can for sure confirm that the above steps dont work on iphone 3gs.
            Problem #1 : Phone doesnt get stuck in recover loop after redsn0w – I get a jailbroken (tehtered) 4.3.5
            Problem #2: When trying to downgrade to iphone to 4.3.3, after installing everything fine, the phone goes into DFU and never comes back. (tried almost everything IREB, IRecover, FixRecover, TinyUmbrella)

            Tried various other options using sn0wbreeze, ireb, tinyumbrella combination with a custom 4.3.3 – Nothing works.

            Bottomline : Either stuck with a 4.3.3 but the phone never comes back up and stays in DFU
            or 4.3.5 tethered jailbroken, unable to unlock.

            Try Recovery Fix to get out of recovery mode. And a piece of advice that iPhone can never become brick using Jailbreak procedures hence its always better to Try

          • Lion_oooo

            But you’re not just jailbreaking, you’re downgrading iOS as well. My recommendation is for folks to stay away from this procedure until the issues with it have been fixed.

          • Test

            Tried the phone still goes back to recovery. I can certainly say the steps do not work, also Lion_oooo was saying these steps work on some level … doesnt know what it means.
            In any case, like the hundreds out there – it didnt work for me too.

          • Lion_oooo

            To clarify, I meant that the downgrade was “successful” but I was hoping to find an untethered solution, which obviously hasn’t worked out. Have you attempted to restore your phone after performing the downgrade?

            @Lion_oooo how come you have successfully downgraded when your iPhone is bricked. I dont get your point.
            @Test: See other comments there are 2 others who have also successfully downgraded. So there is no point saying that procedure is not working if it doesn’t work for your.

          • Lion_oooo

            I successfully downgraded 2 iphone 3GS yesterday and was able to bring them up with a redsn0w tethered boot, but when I woke up in the morning both phones wouldn’t come on, even when I tired to boot them up with redsn0w. Now they simply won’t work. I can’t even return them to 4.3.5. I can’t re-run the jailbreak or anything. iReb, fixrecovery, nothing works, nada. My phones are bricked.

            Hi,
            I think i got the same problem. I got life in my iphone after putting it in pwanage DFU and then restore the ios 3.1.3.
            StarteD TSS server in TinyUmbrella (with no shsh).

            I am now on 4.3.3 once again. Mainly from following the instructions above, with some harsh language and a bit of iFaith. And all good.
            It’s good to see that you are actively answering all these posts. Good man!
            BTW… The issue with people not being able to download the RestoreFiles from RapidShare is simply down to IE8. Use IE9 or another browser and the link will work fine.

      few seconds if driver is installed properly

  • renoster

    Was able to restore back to 4.3.3, but it was tethered, jailbroken but not unlocked. Also, IFaith was not able to get a 4.3.3 blob and stayed on “detecting iOS”; I assume that’s why the jailbreak ended up being tethered.

    I managed to get out of the “detecting iOS” screen by closing iFaith.exe and restarting. The problem now, I receive “unable to find byte sequence…” Any resolution?

  • Barnbuddy24

    can some one make a vedio shows how step by step please??

  • Jeffwhymark

    HI yesterday I could not download the “restore” file from rapid share tried again today still no joy

    I always just use internet explorer but my grandson said download and try google chrome which worked immeadiatly…result now for the iphone that I cocked up by accidently upgrading to 4.3.5

  • Raj

    hiya i am trying this on my iphone 4 can you please explain how long it take on Tinyumbrella regards

  • arc

    how long does detecting iOS in ifaith process takes? stuck there for some time.

    • arc

      gave up. ifaith only support up to 4.3.3
      so how will 4.3.5 work?? it just kept giving unable to find byte sequence and detecting IOS take forever.

  • Greeneyes5066

    Is this method good for Mac user on Lion 10.7.1?

    • Anonymous

      iFaith is windows only so you have to use Windows machine for this procedure

  • IPhone 4 User

    No good for iPhone 4 – iFaith will always stop with this error: “Unknown iOS detected on this device! Aborting…”

  • Rayant412

        just follow the step by step if you have error 20 just ignore it and go to step 8

  • bitbox

    I recently received an iPad (1) already running FW 4.3.5.
    I never owned an iPad before and played around with the device for a few days then decided to jailbreak it since Apple’s restrictions are really exaggerated…
    I soon discovered the impossibility to easily downgrade the FW to 4.3.3 without having a prior SHSH backup.

    I regained hope discovering this article (well, I first found it on Limera1n to be honest)… Since then I tried to apply the described method (and learned a lot about the intricacies of jailbreaking on the road). I’ve spent the last 24 hours trying to get it running, first following step by step instructions then gradually exploring other ways to chain usage of the miscellanous available tools… but to no avail !..

    I currently have the iPad reported as having the 4.3.3 FW installed (in TinyUmbrella) but stuck with the USB cable and iTunes logo. At this point, trying to save the SHSH only reports:

    APPLE is NOT signing iPad 4.3b1 (8F5148b) SHSH requests anymore. All you can do now is select CYDIA and hope that CYDIA has your SHSH saved. If not, there is nothing you can do.

    And same for 4.3b3 and 4.3b3…

    As this last phrase reminds me of what SHSH blobs are, it suddenly seems quite obvious that it will indeed never be possible to rebuild them after Apple stopped signing FW versions prior to 4.3.5. Apple has closed the jail’s doors on it’s customers once again (and for all to this extend). For those of you having a few minutes to spend I recommend you read this article by Jay Freeman (saurik), the guy behind Cydia: http://www.saurik.com/id/12

    I admit I feel quite disappointed being pushed to such a conclusion, but there it is: reality !
    But before I delve into depression, I suddenly remember that, after all, the whole point of willing to downgrade the FW was to have an unthetered jailbreak !.. So WTF Apple, I’ll go for a thetered jailbreak of your sealed doors’ 4.3.5, this will probably be a piece of cake compared to all the time I spent trying to downgrade :-P

    Regarding Lion_oooo’s experience I admit to have some doubts about how he succeeded, IMHO he must have had his SHSH saved wether localy or on Cydia’s server, using TinyUmbrella recovered it without him knowing it maybe ?..

    To conclude I would advise anyone not to loose too much time trying to downgrade FW 4.3.5 unless they have their SHSH saved somewhere… or wether they are willing to learn ;-)
    Let’s hope that an unthetered jailbreak will (soon) be available for iOS5, although since Comex has been enrolled at Apple’s I fear the jailbreak community might loose one of its best elements :-(

      @BitBox: Nice work but i would like to make some clarifications on your points,
      First of all you can never create SHSH blobs of lower iOS versions therefore in the procedure above iOS 4.3.3 is restored before saving SHSH blobs
      Secondly to save and Restore SHSH blobs Cydia servers are used rather than Apple.

  • Smartmbee

    Not working on iPhone 4. In step 4, iphone will stuck on boot logo instead of recovery mode ! Have tried 1000 times !

          Note: You can’t downgrade to an iOS that you don’t have SHSH blobs for and expect to get an untethered boot. Blogs are claiming they found a way. Well… the bootrom explicitly looks for SHSH blobs upon boot. So if they aren’t there… it’ll just go into a DFU loop. When you can write to read-only memory. Let me know. Don’t waste your time.

          • Imstepf123

            I think your right the only way i was able to downgrade was to do a tethered break. is it possible to share blobs

      • Josemari

        sure its working? unthethered 4.3.3 after downgrade? after a million attempts?

        I have no time for trying a million, cause IT IS IMPOSIBLE, fakerman!!!

    I have a an Iphone 4 with ios 4.3.5

    From step 1 to 7 was smoth on step 8 with ifaith I could not save the shsh, first was given me an error that did not recorganize the IOS, so I tried others version from Ifaith and stuck in waiting for Iphone or checking ios. anyway I move ahead did the sn0wbreeze and tried to restore in Itunes and got a error 37.

    If some experience same problem and have a solution I will apreciate.

  • Samsal46

    after reading all the posts here i can see that the only ones successful with this method are those with iphone 3gs.. im having an ipad1. and i dont think i will be able to do it and dont wanna waste my time unless someone comes up with anything other than a 3gs success story!

  • shashank kapoor

    Hi I figured out something after many trials. Before one can restore it should be active in both itunes and tiny umberlla. Those who getting 1600 it is because your device is not connected to tiny umberlla. And error 20 when you not in DFU mode. Please note don’t use iReb to get into DFU because it will then not allow you to connect to Tiny umberlla. If anyone knows how to use snowbreeze which does not force it to DFU mode then that could be a solution.

    Does anyone actually know how to get pass the iFaith error “unable to find byte sequence?” I havent actually seen anyone provide an answer to that question, and that is the only place I am stuck at. Ipad 1st gen shows 4.3.3 on the black screen when running iFaith, but that error pops up repeatedly. Can anyone help with that, please?????

    • Lion_oooo

      I don’t think iFaith works on tethered devices which, if you followed the steps above, your device would be. Anyway, the original poster of the downgrade seems to have made it work. I’d like to know how.

    • arman

      i have the same issue its so annoying if you found any help email me on this 1234arman@live.co.uk ive been trying to fixthis for 3 days :’(

      I would like to know as well. But it seems like no one can give me a straight answer on the subject. Everyone just says “It Worked,” without any actual details or procedures.

      I think this the procedure work for 3Gs only, won’t work Iphone 4

      try iFaith v 1.2.1 instead, that fixed it for me. well fixed that error, still waiting to see if the whole process works though.

      Hi Mokhles first of all thanks for finding this solution as I made my phone brick after updating it. Okie so the problem i find is at step 4. It doesn’t stuck at recovery mode instead it get stuck on apple logo screen. Even when i forced it into recovery mode using home button and power button, it either gave me error 3194 or 20 or 1600. After trying more than 20 times in last 2 days. I left my phone and started using an android phone. Please help I really want my iphone back.

      I use Iphone 4 32gb locked to at&t. 4.3.5 baseband 4.10.01

      Would appreciate if you can sort this problem out. Thanks

      • anonymous

        @shashank – I had that problem before. So you tried just restoring your phone to 4.3.5 after deleting the 74.x.x.x gs.apple out of the host file and you are getting stuck on the apple screen halfway through the restore?

        • Sujanmall

          Just remove all the files inside host file.and if itune finds your iPhone restore just option restore to 4.3.5 if not than delete tune and install past version.

      • Warcraftboy

        This happened to me. You have to restore your hosts file back to normal and you have to restore and update to 4.3.5 in iTunes YOU MUST BE IN DFU MODE or the restore will not work. I tried 10 times then finally tried with it in DFU and it worked first try.

  • Samuel

    Hi Guys, i’m trying this on an ipod touch 4g

    Step 5. Open Tinyumbrella (present in “Restore Files” folder), right click on your iDevice name on the left pane then press on Start Tss Server.

    How do i do this? When i right click my device i only get options to enter recovery, exit recovery and fix recovery.

    Just to confirm in Step 4(After the procedure is complete the iPhone will stuck on recovery mode.) Before i proceed to step 5 i need to put the iDevice in DFU mode?

    Cheers

    • shashank kapoor

      Check this pic :)

      • Samuel

        @shashank kapoor, Thanks! :)

        I know that but when does it mean i have to right click on my device name first?

        If i start the Tss Server straight after it opens it is still the same rite?

        • shashank kapoor

          Well I didnt right clicked but left instead. Which showed this device is connected. Then started Tss server.

          • Samuel

    Can I downgrade ipad 2 to 4.3.3 without jailbreaking? It’s still not supported by redsnow and snowbreeze.

  • Aqk147

    This tutorial may work for the 3gs but DEFINATELY does not work for the Iphone 4. A video may prove this fact. I have tried WITH SHSH blobs and it works but if you never saved your blobs how will Cydia Servers recognise our devices?

    The only misleading point is that tinyumbrella invokes the shsh files to be saved locally which is beneficial if you HAVE SAVED the SHSH. If not…then forget about all this.

    For whom they couldn’t continue the point 8, do the following:
    1- Go to C:WindowsSystem32driversetc, cut hosts file and paste it on your desktop, delete all previous “hosts” and paste #74.208.10.249 gs.apple.com instead to be as the following;

    # For example:
    #
    # 102.54.94.97 rhino.acme.com # source server
    # 38.25.63.10 x.acme.com # x client host
    #74.208.10.249 gs.apple.com

    Points 3,4,5,6 & 7 are the same as mentioned in the topic above.

    8- Start iFaith while your iDevice in the recovery mode NOT in the DFU mode.
    ** Try many times if it stuck on Apple Logo step… USE iREB to enter DFU mode.

    I downgraded my iPhone4 from 4.3.5 to 4.3.3…. SO LUCKY.. :)

        • Jad

          Hey Da,
          You have to follow the instruction below to re-jailbreak your iDevice with 4.3.3:
          1- Connect your iDevice to iTunes and backup.

          2- Go to C:WindowsSystem32driversetc and cut the “hosts” file then paste it on your desktop, open it with “notepad”, delete all hosts and paste ” #74.208.10.249 gs.apple.com ” at the last line, you will get the following

          # For example:
          # 102.54.94.97 rhino.acme.com # source server
          # 38.25.63.10 x.acme.com # x client host
          #74.208.10.249 gs.apple.com

          3- Run Redsn0w and jailbreak the device using IOS 4.3.3 (please download the final version of redsnow).

          4- Once finished, put your iDevice in recovery mode using Tinyumbrella then start Tss Server (please download the final version).

          5- Now, Run fixrecovery (it will be waiting for the iDevice to put in DFU mode), put your iDevice in DFU mode by the normal way (Power + Home for 10 sec then release Power with keeping the Home button OR use iREB-r3).

          6- Now run iFaith to save the shsh blobs.(remember where you saved shsh because you need it to build the IOS using the iFaith, see point 7).

          7- Use iFaith to build the IOS (4.3.3), once finished you will find the IOS on your desktop.

          8- Put your iDevice in DFU mode (if not working try the recovery mode) and open iTunes, SHIFT + Restore then chose the IOS you have built and Enjoy..!!

          100% Working..:)

          • Jad

            Point 2: When you paste the host, please re-copy the “hosts” file to the original folder C:WindowsSystem32driversetc

          • Jad

            Les,
            Jailbreak for 4.3.3 is untethered.

            What is your iDevice IOS?

          • Leslien

            Jad,

            I have iOS 4.3.5 on iPhone 4, SHSH blobs saved by Tinyumbrella (tried with 5.00.9, 5.00.10 and 5.00.11, same results) and got SHSH’s ONLY for 4.3.5 and the 5.0 betas 1 to 6 :-(((

            I tried the downgrade to iOS 4.3.3, steps 1 thru 6 in your post, in step 6 got stuck on iFaith step “identifying IOS…” for a while, after a few restarts trying with iFaith 1.21 and 1.3.2, I successfully saved SHSH for 4.3.3 thru iFaith (both 1.2.1 and 1.3.2 produces the same .ifaith format of the blob file), then followed next steps 7 & 8 … and the only way to boot is jailbroken TETHERED… (unjailbroken phone restored to 4.3.3 goes in DFU on each boot, then after jailbreak again need tethered boot). So, no use of this downgrade for me, as we already have the tethered boot also on jailbroken iOS 4.3.5.

            Well, my question was, after you downgraded to 4.3.3 with the blobs saved by Faith, did you manage to get to untethered boot or you are booting still tethered?

            BTW, I played a little with the 4.3.5 and 5.0bX .shsh files saved by TinyUmbrella and figured out they are gzipped plist files (attention: “gzip.exe -n”) editable in human readable XML with plist Editor (I am on Windows). I figured outwhere to “stitch” the hashes extracted by iFaith (a somewhat lenghty process involving BinHex decrypting of the sections of the XML blob and re-encrypting after binary edit of the files with copy paste of the iFaith hashes … I can provide more info if someone is interested). Playing around the .shsh I managed to recreate a 4.3.3 .shsh in TinyUmbrella format that was successfully read AND RECOGNIZED AS VALID SHSH blob file by Tinyumbrella (all 5.00.9, 5.00.10. 5.00.11), but, when I tried to restore the device to 4.3.3 with this recreated SHSH file, got the same result as above – DFU or tethered jailbroken 4.3.3, so no luck… Today I saw the new redsn0w 0.9.9b1 has a SHSH verify function, tried it and it says it failed to verify all 19 blobs in the “recreated” 4.3.3 SHSH… (had to reconvert it in XML format as redsn0w does not read the Tinyumbrella gzipped plist shsh; redsn0w however sucessfully verified the original 4.3.5 and 5.0bX shshs converted to XML).

            I will quit trying the downgrade and will wait for the announced untethered jailbreak for iOS 5…

  • Jurhos

    Just downgraded my iPhone 4.

    1, 2, 6, 7, 9 and 10 (as above)

    It works I HAVE JUST JAILBREAK IT NOW.

    Thanks.

  • ALIEN44

    Hi well in a word (pointless) I got it to work on Iphone 4.
    And all you will end up with is a tethered jailbreak no
    Unlock. No shsh to save. If you do manage it your self.
    And then run redsn0w to run tethered. goto cydia and look
    At the bottom of the page it will say ios 4.3.3 BUT then
    goto the top of the page and it says shsh: IOS 4.3.5
    That’s why it is tethered and no unlock. So Im going back
    To 4.3.5 hopefully wish me luck.

  • Darren

    Not working at all, i’ve spent 9 hours straight trying to get this working.

    I’ve took 5 hours to get past the iFaith , which kept showing error byte seqeuence.. I used an earlier version instead, and it worked fetching SHSH blobs.

    Then,i thought all was well , as i happily built a custom IPSW, only to find out after installing it, it doesnt boot……( stuck in DFU )

    What a waste of time….

    • Ahmed Alsurmi

      Fanx 4 da fast replay n im waiting 4 untetheard 4.3.5 or 5.0
      When do u funk ultrasn0w will support it this 4.3.5 n 5.0

      • Ahmed Alsurmi

        Sorry fink

    • Darren

      Ooh by the way, i was trying it on an iPhone 4 ,

      No matter what i tried , the apple boot logo would not appear, EXCEPT for the original 4.3.5 IPSW.

      I’ve flashed countless times , reflashed countless more, edited hosts files to each websites preference , used all tools available as described – tried them in all sorts of order. to no avail .

      If only someone who got this working could possibly post out a SIMPLE step by step guide or better, youtube it for everyone here.

      As of now, i see NO ONE that got it working, bothered to even show that they got it working.

      Not an accusation , but sounds fishy – trolls .

      Congratulations, you just wasted 9 hours of my time trying, i hope it made u happy :)

  • Jdolo809

    after using red snow it didn’t even get stuck! man i screwed what do I do now? I got the cydia logo atleast…

  • Brennonbs56

    Does this work for iPod touch 4, and when i tried with this device when ingot to the iFaith stage it would just say on the screen that it couldn’t find the bytes. What did I do wrong??

  • vokab_san_luv_btk_mvk_dm

    I’ve tried this before and I didn’t get stuck in recovery mode. I’m 100% sure that redsn0w was pointing at ios 4.3.3. How the heck am I supposed to do this properly if step 2 doesn’t even execute as it should?

  • vokab_san_luv_btk_mvk_dm

    its not stuck in recovery mode it needs to boot tethered, fuck this shit

  • Kot

    Hey I can’t get me 3GS out of recovery after I do all the steps. Please help.

    I never actually got error 1013 from iTunes but it finished installing and went straight back into recovery which is what’s suppose to happened, but when I try to get it out with Fixrecovery it just goes threw a bunch of code and seems to crash and I’m back at recovery. I tried with upbrela fix recovery nothing. I tried iFaith it reads the phone, reads that it’s at 4.3.3 and gets stuck on apple logo. So I’m completely stuck in rec mode. Please help, I still have hope for the 3GS! Thanks

  • Felipe

    After almost 10 hours I’m totally tired of trying that! I have an iPad 1 3G 64GB and it was with 4.2.1, but I actualized it and now it’s with 4.3.5. I’ve been trying to downgrade it but I ALWAYS get ALL the errors mentioned at the post! I got 3194, 1600, 1604, 20, and finally 37, the one that I couldn’t get over. I tryied to use a snowbreeze custom version and the oficial version of 4.3.3 and tryied even the iFaith and iRecovery but didn’t work, iTunes keeps teling me there’s the 37 unknown error. Ans my ipad was on a boot loop. So I restored it to 4.3.5 again and that’s it =/ If anyone can help I’ll live it! Thanks, Felipe

    • Xilixx

      i now how to avoid error 37. You just should do custom version with Snowbreeze but unchek all those possibilities (custom logo and so on)

  • Jimdaza

    So I Found a way to jailbreak iPad 1 and avoid the stupid infinite loop: use iFaith 1.2.1… Totally works… and I’m Totally happy =)

    • I Zer0weaver

      Untethered?

    • Edplage

      Im trying this one 1.2.1, but return “Unsupported Device!” error.

  • Wisely

    After millions of trial and errors, managed to downgrade my phone to 4.3.3. The good ends there, i’ve gotten a tethered jailbreak and the phone has no signal. Doesn’t matter about the signal stuff, cos’ i know there are ways to get it settled. But what about the tethered??? It’s frustrating! So can someone show me the light please?

  • Lohatz

    Im not getting an error when im downgrading itunes just sais its in factory settings and then its stuck in dfu mode and i cant get it out with fixrecovery and ideas?

  • RockstarFromMars

    will this work for my ipad2 that is wifi only and is on 4.3.5

  • RockstarFromMars

    redsnow cant see my 4.3.3 ipsw for ipad2(wifi)

  • RockstarFromMars

    well, it can see it but it cant recognise it.

  • Matmotor

    Remember this only tested on 3Gs not iPhone 4 . All the Files of ipsw Firmware are not the same… Do take note guys n gals ^_^

  • Ramand

    Worked on Iphone 4 :) Thanks.

  • Matmotor

    this wat i get … dun tell me my iphone still detech ios 4.3.5 ?

  • Meatpump

    why would you guys try this with your iphone 4. It is to valueable to risk it being bricked. Koolmobile is wrong an he is a fraud. He has not tried this for himself

    • NONO

      THERE IS NO RISK SINCE IT SOFTWARE CASE ,IT WILL BE RISK IF U DONT KNOW WHAT ARE U DOING , (ITS ALMOST IMPOSSIBLE THAT SOFWARE CAN DAMAGE HARDWARE) SO THATS WHY ITS NO RISK

  • Kamus003

    those who cant downgradee and get stuck on DFU mode, can try restore the 4.3.5 with itunes (just itunes, close all the other things, like tyniumbrella, etc.) to recover from dfu loop mode, after that you can try again if you get the risk, I give up, cause just borrow me the iphone 1 day.

  • ritavarela26

    Hello! Is there any tutorial for mac users?

  • Noah_koop

    i keep getting “unexpected error during preparation” in redsn0w……. any suggestions?

  • MyNameIsBom

    Does this work on iPod touch 4G? I helping my friend downgrade his 4.3.5 iPod touch 4G to 4.3.3… I’ve bricked it using Redsn0w for 4.3.5 jailbreak tethered.. So he can get the 4.3.3 Jailbreak… Anyone tried it on an iPod touch 4G? does it work?

    • MyNameIsBom

      ** it’s not bricked anymore **
      but still need confirmation if downgrading works on iPod touch 4G 4.3.5

  • Awad123456789

    it worked for me i swear i was on iphone 3gs 4.3.5 now on 4.3.3 for step 8 use ifaith 1.2.1 it seems to work the one in restore file dont work i have pic proof

  • John_smk11

    ifaith said: unknown ios detected on this device aborting.
    What’s the solution for this? Plaese.

  • Willian Sousa

    WOW, all the time i’m using iFaith 1.3.2 … no success :(
    Using iFaith 1.2.1 … Saved my shsh for 4.3.3, downgrading NOW. Thanks thanks from brazilian boy :)

    • Bruno Azevedo

      Willian, voce conseguiu fazer o downgrade pra 4.3.3 untethered ? Cara nao estou conseguindo fazer no meu iPad1 64GB 3G. O negocio so fica em DFU o tempo todo.

      • Said

        Algum sucesso ?? Obtive o mesmo resultado em 4 idevice diferentes

  • Bruno Azevedo

    Does not work at all for iPad 1 64GB 3G.
    Everything fine until step 6. At step 6 i can only restore to 4.3.3 if i take it from RECOVERY mode to DFU mode.
    It will restore to 4.3.3 , but after that there’s no 1013 error. Device will loop in DFU mode and that’s it.
    FIXRECOVERY don’t fix the DFU loop, also restoring to a custom sn0wbreeze 2.7.3 firmware will not work either.

    Algo step 8 don’t work, it will show iDevice firmware 4.3.3 but after that it will loop with message “BYTE SEQUENCE NOT FOUND”

    The only way to get out of DFU loop now is using the “Just boot tethered right now” option of redsn0w 0.9.8b4.
    The device will get out of DFU loop and boot normal with firmware 4.3.3, but once you reboot it or turn the device off, DFU loop AGAIN.

    IN RESUME, IT WILL BECOME A TETHERED 4.3.3 iDevice

    NOT POSSIBLE TO MAKE IT UNTETHERED AGAIN

    IN THIS CASE I PREFER TO HAVE A 4.3.5 TETHERED THAN A 4.3.3 TETHERED

  • eLgin

    i tried this and it works but the only problem is when i turn off my device it doesn’t turn off but i turns in DFU mode…im now restoring my iphone 4 to ios 4.3.5 again…and will just wait for the untethered jailbreak for ios 4.3.5…

    and by the way when i was in step 3…my phone wasnt stuck on recovery it just booted normally…

    • Bruno Azevedo

      Same problem i have with my iPad1. One question, did you updated your phone from 4.3.3, or is it a factory 4.3.4 / 4.3.5 firmware ?

  • Ipad1 FOREVER

    IPAD 1, near success but…

    Dear kool, in final final step i tried to restore to 4.3.3 signed by snowbreeze (or ifaith, is the same).
    FOREVER error 37 at 60-70% of process (when indicator in my ipad1 is in 60-70% position during restoring fw). At this moment iTune is in “verifying installation” moment. Where the problem is? Is Error 37 fixable?

    • Graficofotografo

      Ipad now is in the DFU mode permanent. Only method to restor via iTunes is Pwned DFU via iFaith BEFORE itunes.

    • Nono

      just try to download another IPSW with firefox or with MAC system not windos explorer

  • al

    I’m stuck on step 7. I get the 1013 error but when I run fixrecovery, theres text on the device and it goes to dfu mode after that. I googled the problem and it said delete gsapple.cm host entries but I would get a 3194 error. I suppose theres supposed to be an apple logo after fixecovery. Is there anyway for me to restore to stock 4.3.3 or 4.3.5?

  • savko

    unable to find byte sequence?”
    use ifaith 1.2.1 WORKING 100%!
    ok, i used ireb to enter dfu, then open tiny umbrella, start server, before that uncheck Set hosts….
    Open Itunes 10.4.80 (i used that version) and restore 4.3.3… i had no error 1013, and after restoring i opened ifaith 1.2.1 and do all process… after that created costume ispw with snowbreez and restored with itunes…. tiny umbrela is opened all the time and server is not stoping at all.. hopi its work.

  • Tandraicel

    If I downgrade from 4.3.5 to 4.3.3 will I loose all the current apps, folders and other things like text messages, call logs, etc? If I downgrade and do the option+restore with the 4.3.3 firmware and update my host file will itunes change my phone to 4.3.3 from 4.3.5 and keep everything else the same on the phone? So visually I wont notice a difference on the phone but it will be 4.3.3 and available for untethered jailbreak?

  • Lil Domco

    i made the steps but after the jailbreak was done , my divice started and now iam on 3.3.5. and i have a white cydia app that dosent work…
