Discussion: Help needed........plzzzzzz

"Hey Guys.....i was referred to this website by the HTC customer care......
I am in serious trouble.....
I bought this new tilt which had the At&t rom and worked really great.....Dont know what got into me.....I read a lot about custom roms and I installed Duttys official WM 6.1 after installing the Flash Hard SPL......It was perfect except the phone call function wasnt working any more.....I mean when I called my home number....i got the ring, but when the phone is picked up i couldnt hear anything nor did anybody on the other side.....I tried this many times on different numbers....
Realizing the mistake I downloaded the latest tilt rom from the HTC website and installed it......The phone restarted fine....screen alignment.....showed the today screen and then it goes through all the AT&T customization......The phone restarts after the customization.....shows the AT&T initial screen and then the 3G animation......after that it goes to a very dim dark blue blank screen.......the phone is on...the key lights turns on when clicked.....but the today screen doesnt boot up......This is were I am rite now.....stuck with this blank dark blue screen......The phone goes to standby more after about 1 min I guess.....and when the phone is waken up from the standby mode I see a screen with a mixed color screen.....I am not talking about the red blue green boot loader screen....this is colors all over the screen.....each pixel is different color.
I dont know what to do.....
Please if anyone can give me some advice and help me out......
Thank you so much in advance....."

"Sorry....forgot to mention that.....I did do hard reset by holding down the soft keys and by inserting the stylus......It goes through the entire cycle of reloading....today screen....customization and finally I end up with the blank screen I talked about before which comes right after the windows screen at the startup....."
