Root [Solved] Screen Dead - Unrooting Blind?

[RainWind]

My screen on my EVO just died. Started flickering, then it just went out. I'm sure if I sent a rooted EVO to them they'd claim that my custom ROM killed the screen and make me pay full price for the replacement parts... which is ludicrous.

How do I go about unrooting and restoring it back to stock completely blind?

Edit: More specifically, if I blindly flash the PC36IMG how am I going to tell if it's back to S-OFF? If I wipe out the SD card leaving only the format all zip, run that (I think I could navigate to it blind lol), then run the stock RUU it'll be back to how it was stock except I can't check S-OFF.

hmm.. that's a pickle. As of checking out if S-OFF is back, i remember reading on one of the wallpaper threads from 2008 or so, a G1 user was using ADB to take screen shots..? I think that is what I read.

If that is possible, you might be able to screen shot the boot loader?

Problem solved, yay. I did a nandroib backup from ADB and after I typed reboot the screen came on long enough for me to get it back to s-on and flash the RUU. Hopefully I can get it taken in tomorrow for repair.
