Ok, I had rooted my DINC with unrEVOked 3, but now I need to return it back to stock. I had found some PB31IMG.zip files, but nothing has been working. I held the down/power on, went under recover, install sd/update.zip (i changed the name) and it's keeps telling me the file is invalid or unreadable. Is this even the right file? I just need the stock 2.2 build w/sense. Can anyone please help me? I have read in the forums, but nothing so far has helped me any. Any help is greatly appreciated!!
