Well I don't know why it doesn't change your recovery. That makes zero sense. The kernel and recovery is the same thingThanks for the try! No joy - same result as last time. Installing Shift-JB doesn't have any effect on the recovery (tried to install from CWM/PhilZ/TWRP) - just bricks the OS. Is the OS kernel separate from the recovery kernel or do they both use the same?
I would try it with CM 10.2 for you but the nightly build boot-loops on the phone (without even installing Shift).
