The latest update for the Google Nexus One is rolling out now. Although the phone is quite old, Google has kept their promise and is continuing the issue the latest updates to users. The latest of which is Android 2.3.6 (build number GRK29F) and contains mainly security and bug fixes. The process may not work if you’re rooted, and you must be running 2.3.4 GRJ22. If you’re currently running Android 2.3.4 (GRJ22) then follow these instructions to manually update your phone:
- Download the update file from Google’s servers GRK39F-from-GRJ22 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).
- Move the file to your SD card’s root using your favorite method – the easiest way is probably mounting the phone as disk using a USB cable.
- Reboot your phone and when it starts booting back up, hold down the Power and Volume Down buttons.
- If you see Bootloader, select it.
- Select Recovery.
- The phone will reboot into recovery but first it’ll show an exclamation point and a triangle. At this point, mash thePower and Volume Up buttons a few times until the recovery screen shows up.
- Select Apply sdcard update.zip, which should start the update process.
- Reboot and enjoy Android 2.3.6.
