Instructions (non-rooted “adb sideload”):
*For some reason on my Galaxy Nexus, I did not have the “adb sideload” option to update via stock recovery. If you do, these instructions are for you. If you get into stock recovery and don’t see the option, you’ll need to jump down to the next set of instructions.
*I’m also going to assume you know adb commands if you know about the sideload command.
*These are also the abbreviated adb sideload instructions. For the full guide, check out
1. Download the file from above to your computer.
2. Plug your phone into your computer and type “adb reboot bootloader” in your command prompt.
3. Your phone will boot to fastboot.
4. From here, scroll down with Volume Down to “Recovery” and select it with Power.
5. When the exclamation point and Android appear, tap Volume Up and Power at the same time.
6. You should now be in recovery.
7. If you see “adb sideload” as an option, choose it. (If you don’t, jump to the next set of instructions.)
8. From your computer terminal, type in “adb sideload <filename of the update file>”
9. Your phone will prompt you with a set of instructions for updating.
10. Follow them, update your phone, and enjoy.
Instructions (non-rooted):
*If you tried the instructions above and are not seeing “adb sideload” as an option in stock recovery, you’ll have to use these instructions. The only way to update at this time, is to temporarily flash a custom recovery. It’s not hard and will not ruin your phone by any means. Temporarily flashing means that after you install the update and reboot, your stock recovery will return. This will not root your phone.
*This Nexus toolkit is the one I’ve chosen for this set of instructions. [

4. Then choose option 1, boot to Clockworkmod Touch Recovery.
5. Follow the next on-screen instructions to boot into Fastboot mode.
6. Watch your phone boot into fastboot, flash recovery, and then take you to recovery.
7. From there, choose “install zip from sdcard.”

9. Select it and install the update.
