I just applied the 6.5 ROM update and it seemed to go well enough, but when it booted up for the first time my touch screen doesn't work anymore. This means that can't touch the screen to setup the phone and the welcome screen stays in the way and I can't get it to go away. The phone looks like it finishes booting up behind the screen because I can receive calls and use the buttons on the phone (the touch screen doesn't work on the caller ID screen to slide to answer, but I can asnwer the phone with the call button), I just can't see what it is doing behind the Welcome screen (the yellow and orange one that says "Tap the screen to set tup your Windows phone").

I'm an IT network guy that knows a decent amount about computers, but I've never spent the time to learn how to cook my own ROM's etc (I was never completely clear on how legal that is) so I've always just stuck with the carrier released stuff. Is there some place I can get my hands on the original 6.1 Sprint rom so I can put the thing back? I've already tried a soft reset, hard reset, and I've even re-applied the 6.5 ROM. Same results each time.

Any ideas? Fixing it somehow would be best, but getting back to 6.1 would at least let me use the phone for more than just receiving calls.
