Ok, this worked for me as of 10/20/10, i had my phone rooted by unrevoked, I am like many of the people here who kept having issues with all the PC36IMG.zip not working. I have extracted a new PC36IMG.zip from the ruu's and have not had any issues. I also had the dreaded "main version is older" issue. This seemed to take care of the issue! Im now back to stock! Step 1 you will need to go here: http://downloads.unrevoked.com/forever/current/unrevoked-forever-son.zip If you used Unrevoked Forever at any time, flash unrevoked-forever-son.zip from recovery until hboot shows S-ON(Credit to djR3Z's xda tut) Step 2 http://www.megaupload.com/?d=108Z9R8Y This is the PC36IMG.zip file that you will need - Put this on the root of your sdcard - Boot into hboot and let it load up the PC36IMG.zip - It will run like a normal update - Reboot when finished - It will do a few other things (Load radio and update) - After it fully loads you should be back to complete stock!!!! Lemme know if this doesn't work for you LIKE I SAID THIS WORKED AS OF 10/20/2010!!! I am not responsible for damages to your phone! You chose to go the route you did, so face the consequences, I'm just posting what has worked for me, so use at your own risk! Love the android, love my evo!
