Unhappy [Q] White HTC screen keeps popping up

I tried searching the site but I found nothing on my problem so here I go.
I installed MAGLDR113_DAF then followed by MCCM HD V5.0. My phones been doing awesome until today. I was just roaming on my phone when all of a sudden, it showed "No Service", followed by "Emergency Calls Only". Next, the screen "HTC quietly brilliant" pops up for about 30 seconds to a minute and then a black screen appears for about 2 seconds, then it goes right back to the White HTC screen. I read around and it said to let it boot for about 20-30 minutes, but I waited 1-2 hours and it just kept on going. I then took out the sim card and booted it and everything was fine, (just no space for any memory). Please help. Thanks!
