Can anyone confirm that the latest OTA update works after flashing to stock .211? I'm on .211 now but was rooted. I tried permanent unroot using the supersu app with no luck, unfroze all apps, wiped phone but none of this worked. So it looks like I have to be 100% stock ICS .211 right? I dont want to waste anymore time on this update unless others have gone back to matty's stock .211 and been able to use the latest update.
