I rooted my thunderbolt using the ADB method and everything went fine until i tried installing CM7 1.4RC. I noticed that I did not have a signal at all even though I had upgraded to the 2.5 radio. I thought maybe it was the ROM so I tried MIUI and OMFGB to see if I could get it working. Even with the new ROM as we as every radio combination I could find I still don't have any 4G signal. Is anyone else having this problem or is this just me?
