Unrevoked did not S-off USCC Desire

[gtdq]

I did unrevoked last week and got root. When I tried to uninstall bloatware, I found out that s was still on. I have backed up with titanium backup, if I wipe my device and unrevoke again, do you think i could get s off? I tried formating my SD card (fat 32 w/ default allocation size). I am using a USCC Desire this is the Soff error message I get.

Got device:
@PID: 88,"BRAVO_C"
Got radio version:
2.05.10.08.11
E:unsupported radio version
E:Update failed. Check /sdcard/soff.log.

I installed roam control to allow forced roaming do you think this had anything to do with the unsupported radio? Thanks for the help.
