so i download das bamf and installed it, flashed it and have service on my phone. but earlier today i installed Cm7 and then virusrom and they both did not give me service...the cm7 did give me service but after a hour or so dropped all service. ive been trying to find a radio for my thunderbolt but all the links are outdated and wont let me open. i was wondering if i have to worry about my service dropping like Cm7? and if so what radio could i use to acquire service if it does drop.
