Before you do anything, you must unlock the bootloader on your RAZR i. See my thread here for details: http://forum.xda-developers.com/show...php?p=32576654
If you do NOT want to unlock your bootloader, use this x86 version of motofail2go by Dan Rosenberg: http://126.96.36.199/~batakang//ftp...l2go_razri.zip
What does this do?
Flash this .zip in Clockworkmod by turl1 to Root your device.
Brought to you by Batakang and turl1 for his Clockworkmod Recovery. Cheers!
