In case you have forgotten this all time favorite Android phone. Nexus one is one of the most popular Google phone launched in January 2010. It was equipped with 1GHz Snapdragon CPU from Qualcomm along with 512MB of both RAM and ROM, 480 x 800 capacitive touchscreen with AMOLED display, WiFi, the prerequisite AGPS chip, and a 4GB microSD slot card which can be expandable up to 32GB.
Nexus One has been now upgraded to Android 2.3.6, Build GRK39F which is actually out to remove important bug and security patches. Although many Android users must have been upgraded to newly launched phones but those who are still keeping it have got a good opportunity to upgrade their Nexus One up to Android 2.3.6. I have mentioned below step by step guide on how to update Nexus One up to Android 2.3.6 build GRK39F.
- Download the update from here (Google official – d323ca384aaa.signed-passion-GRK39F-from-GRJ22.d323ca38.zip).
- Rename the file to update.zip. Note that if you’re using Windows, just rename it to “update” (no quotes, of course) because it’s already a zipped file.
- Copy the update.zip file onto your microSD card.
- With your Nexus One off, hold down the trackball and press the power button.
- You’ll be booted into a white screen with three Android robots on skateboards. Select “Bootloader.”
- On the next screen, select “Recovery.”
- Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.
- Now press the power button and volume up button at the same time. It could take a couple of tries.
- Now (using the trackball this time) choose “Apply sdcard:update.zip” and let things run their course.
- Reboot and enjoy
