[SuperAndroidMan]

When I buckup my stock rom 3.70.651.1 I use ClockworkMod recovery 2.6.0.1. to backup it. Now im on ClockworkMod recovery 5.0.2.2 when I need to go back to stock rom it just says there is No files found . I really need to go back to stock rom and unroot this phone to take it for some repairs to sprint. I dont know if this will help I use this old root method unrevoked 3.3.1 on that time to root3.70.651.1 pls help hardware version 0004

welcome to the forums!!!!!!!!!!!!!!!!!!!!!!!
moved you to the rooting section.

go here:http://androidforums.com/evo-4g-all-things-root/194918-rooting-dummies.html. there is an unrooting section. you do not need to be on a stock rom to unroot your phone. basically there is two steps.
1. flash the s-on tool
2.install a stock rom and recovery via PC36IMG file.

follow the directions in the guide.
