My INC is already rooted running 2.2
I’m selling my phone and want to return it to stock if possible.
Can you point me to a guide or explain how to?

I want to restore to the original recovery, wipe the user data, wipe the cache, and flash a the system image including (boot.img, recovery.img, system.img, userdata.img)…

I know you can download system images here : http://developer.htc.com/

I have my drivers setup adb is working and such, but I’m not sure how to go about this.

Thanks in advance.
