Hi everyone, I bought my Razr M a few months ago, and applied the RadioComm unlock as linked by teddyearp above, to work on T-Mobile prepay. At the time it was working fantastic, stable and getting fast data speeds (H+ as reported by phone). Recently I had to re-image the phone. It wouldn't boot so I couldn't see the software version, so I used an 183.46.10 image as it seemed recent enough, and allowed me to root/unlock the bootloader, which I did. I applied the same RadioComm hack and have it working on T-Mobile, however now it locks up and reboots multiple times daily. If I set the "Preferred Network Type" to "GSM/UMTS", and then "Select Network" to "GSM Only", the crashing stops (saw this somewhere on a forum awhile back). However this makes the data speeds pretty terrible. Short of experimenting with flashing back to other older images, has anyone encountered this issue and has a solution that gives one full data speed still? Thanks!
