Weird Radio thing

[doomsmythe]

Okay, so I had my Diamond flashed to Revol, which is like Cricket or Metro PCS here in Toledo. Then one day out of nowhere it just started searching for signal. I thought maybe the antenna got damaged, but here's what I have discovered. I was using Mighty Rom. I flashed the stock Sprint radio and I get signal. I flashed every stock rom and get signal from the radio. Then once I update the PRL for Revol, no signal at all. Anybody got any clues on this because I am out of ideas and have scoured the internet for clues.
