Time to root your Galaxy Nexus now that @Koush has released official Clockworkmod Recovery for the LTE version. We have gone ahead and posted the manual instructions for you, because well, if you have a Nexus you should probably know most of these standard adb and fastboot commands. It’s not hard by any means, especially knowing that you all have the SDK set up after unlocking your bootloader. Should take all of 5 minutes, maybe less.
Rooting and flashing a custom recovery:
*Unlock your bootloader first. [Instructions]
1. Download ClockworkMod Recovery for the G-Nex. [Download]
2. Place that file in your SDK/Tools folder (same place as your adb.exe).
3. Download the superuser file aka the root file. [Download]
4. Place that file in your SDK/Tools folder.
5. Open a command prompt from within your Tools folder and type the following:
adb push su.zip /sdcard/
6. Then reboot into the bootloader:
adb reboot bootloader
7. When the boot menu loads, flash the new recovery image:
fastboot flash recovery recovery-clockwork-220.127.116.11-toro.img
8. When that finishes, use the volume keys to highlight “Recovery mode,” press power to select it.
9. From recovery, scroll to “Install zip from sdcard.”
10. Then “choose zip from sdcard.”
11. Choose the “su.zip” file and install it.
12. When that finishes, back out of recovery and reboot the system.
13. Enjoy being rooted with a temporary recovery. (Permanent instructions below)
Afterwards, you will want to install ROM Manager from the market and have it re-flash recovery for you.
Make your first backup:
1. Now that you are rooted and have a custom recovery, it’s time to make your first clean backup.
2. In ROM Manager, flash Clockwork recovery again (it’s the first option up top).
3. Then tap the option to reboot into recovery just below that.
4. Once in recovery, scroll down to “backup and restore.”
5. Choose “backup” and let your phone create a backup.
6. When finished, back out of recovery and reboot the system.
If you want permanent Clockwork Recovery (via XDA):
1. Install Root Explorer from the market and delete /system/reboot-from-recovery.p – *Mount as R/W first*
2. Reboot into Fastboot Mode: Power off your device and (Power + Volume Up and Down)
3. Flash CWM (fastboot flash recovery recovery-clockwork-18.104.22.168-toro.img)
4. Reboot into OS (fastboot reboot)
5. You now have CWM recovery permanently installed
