credit to @peteralfonso for the insecure boot.img which allows this to remount system and this way install su binary and Superuser.apk

This are the instructions for Galaxy Nexus

they require basic knowledge of fastboot adb and using command prompt/terminal

works same way on linux and windows

Be sure to have fastboot and adb ready and working

extract somewhere and you will get 4 files su, Superuser.apk , boot.img and drivers

turn off the phone

Boot into bootloader mode (Vol UP+ Vol Down + Power) then execute this command, be sure to have fastboot and boot.img on same folder or be ready to type a long path pointing to your boot.img

REMINDER: by doing fastboot oem unlock you will completely wipe your device so be sure to backup anything important

execute this command

Code:

fastboot oem unlock

fastboot boot boot.img

edit: thanks chirality forgot the oem unlock

the device will reboot and start in unsafe mode where you can enable adb as root usually on production devices this is not posible

Be sure to enable adb debugging on menu

back to command prompt

Code:

adb root

adb remount

adb push su /system/bin

adb push Superuser.apk /system/app

adb shell chmod 06755 /system/bin/su

adb shell chmod 06755 /system/app/Superuser.apk

adb reboot

and you are done and youve got your Galaxy Nexus rooted

This process does not involve flashing another boot.img, it just boots once with it and after that returns to original boot.img YOU ARE PERFORMING THIS AT YOUR OWN RISK! I AM NOT RESPOSIBLE FOR ANY BRICKS OR PROBLEMS!
