So I'm trying to load a PRL into my Tour, to check out service on a possible provider....w/TMO right now. Most of the ones I see on YouTube use QPST for there BB's. I already have QPST, I've flashed PRLs of a coulple phones with no issues (not BBs) but it wont detect my Tour or my GFs Curve. I've tried removing the desktop software cuz I read that can screw it up, running on just straight USB modem drivers, which don't work. any suggestions?
