I was going to post a new thread, but since I found this I figured I would just post my problem here and hope that someone knowledgeable will help. I also need to un-root as I need to take my phone into the sprint store for service. I used the unrevoked 3 and unrevoked forever. I know I need to download and flash the s-on tool, and I know I need to flash that just like a rom right? Is that the first step? And then what, do I just download the stock pc36img from toast's site and flash that? Any help would be much appreciated.
