So I rooted a friends Thunderbolt a few weeks (11/28) ago with revolutionary and stock gingerbread. She brought the phone to me today with the little blue Android guy and a triangle looking like it tried to download an OTA update. Now when the phone turns on, it reboots after 10 seconds, and tries to install an OTA. In previous occasions, I just factory reset, and it would bring me back to a fresh root. But this time, I did a factory reset and now don't have 4g, only 1x. O.o
I guess what i'm wondering is, shouldn't revolutionary have blocked this update from even occurring? She knows better then to even look for updates without consulting me so I know she didn't do it. Now I'm stuck looking through the forums for the correct radio version. I'm also worried because I have rooted my thunderbolt and another friends the same way... is this going to happen to me also?
Any insight on this odd issue would be greatly appreciated.
