I got the Thunderbolt the day that it was released and played around with it for a month, then decided to root it, my buddy came over and helped me root it, only when he did that he really didn't explain things like he should have. So a few weeks after the root, I wanted to flash a new rom on it, so he again helped me, but without explaining everything. So then I read about the new Gingerbread Rom (BAMF 2.3) and decided that I played around with the phone enough that I would be fine to flash it myself... WRONG! I forgot to back everything up like an idiot and flashed away... When I got the Rom on there, it wasnt working right so I read some more forums and it said I needed a new radio, so I flashed the radio MR 2 (with GREAT success lol) and tried it again... So now it EVERYTHING else EXCEPT my service is working... Idk what to do. A few of my friends say that I'm screwed, then a few more says I just need to flash everything back over to Froyo, radio first. Question is... Do I take out my SIM card when I do all this?
