Default Lost root access somehow

I'm completely stumped at this point. I've been running Darksides beta builds with no issues until I flashed his latest one and then had no signal, data etc. I used the tmobile radio leak as well. So after a night of wiping over and over with his custom script I went back to his previous build and everything worked. So today I tried opening root explorer and it failed. So I downloaded root checker and it said no root. So I wiped again flashed and flashed the SU.zip but still no root. Guess I will have to go back to my G2x until I get this sorted out which blows lol.
