Procedure

1. Download the update file GRK39F-from-GRJ22 (you have to be on GRJ22 for this to work) and rename it to update.zip (make sure it’s named update.zip and not update.zip.zip if you’re using Windows and have it set to hide file extensions).
2. Move the file to your phone’s /sdcard directory using your favorite method – the easiest way is probably mounting the phone as disk using a USB cable or use your favorite file manager (mine’s Total Commander).
3. Reboot your phone and when it starts booting back up, hold Volume Up + Power.
4. Select Recovery.
5. The phone will reboot into recovery but first it’ll show an exclamation point and a triangle. At this point, mash the Power and Volume Up buttons a few times until the recovery screen shows up.
6. Select Apply sdcard update.zip, which should start the update process.
7. Reboot and enjoy Android 2.3.6.
