I didn't run any ruu. Didn't relock my bootloader nothing like that. The simplest and least likely way of messing anything up I found was extract the ruu for ics. There will be a zip.called Rom.zip. I removed the hboot update itself (we don't need that one) from the zip. Then I.did fastboot reboot OEM-42. Fastboot flash zip Rom.zip.
Took a few minutes to flash. Rebooted and everything was working. The hboot I have is already higher (the one they included with juoponutbear) then the is update. But you need to get the new firmware from the ruu fo be flashed still.
Follow the guide previously posted and you should be fine tho. I just used a slightly different method to do.it myself
