Return Wildfire S to stock
I've had some problems with my rooting, and want to start fresh by returning the whole phone to stock. I already know how to relock and unlock the bootloader and root my phone, but the problem I'm trying to understand is getting back to complete stock. My phones is S-On and the current ROM version is 2.26.401.3. I've seen that If you relock the bootloader and run the RUU the problem is solved. However, I can't use the RUU as the HTC Dev website has older versions and of course using an older ROM version doesn't work at all. How do I return the system and recovery back to what they were? I've been looking for hours, and I'm afraid that If I keep messing with this phone I will brick it.
What could work is if I found the boot.img, system.img and recovery.img files that I could fast boot over, but I tried that before using someone elses files and It messed things up.
This is the very similar procedure I followed but with my Wildfire S instead. http://www.youtube.com/watch?v=1g5gEf2wgS4
Much help appreciated
