Stuck at splash screen

[thattekguy]

Hi, I have a xv6800 WM 6.5, I am not a pro like some of you guys, so please excuse my stupidity. I tried to change to a new rom this morning and I guess I used the wrong rom update utility, because now it is just stuck at the second screen when powering up. This screen says codefest 2009 brought to you by XDA-developers...etc etc. The first bootup screen says r 3.42.50 d 2.17, I think my update downgraded half the phone. I can get into bootloader and run the bootloader unlock exe, and that works so I think the pc might be able to talk to it. Activesync however, does not see the device. Please help, am I bricked? Thanks.
