I've tried most of the roms, all of the NexusHD2 roms back to CM9 and a few of the newer roms -> Pixeldroid, Evo HD2 but whenever I get connected to the tmobile data network my phones freezes. Initially i thought it was due to overheating, but i've used cpu master to restrict clockspeed to 700mhz and it still freezes.
No problems when I do not have a sim in the phone and no problems when I'm on wifi, but once connect to mobile data it freezes.
I've started from scratch and reflashed HSPL, reflashed radio, reflashed bootloader, task 29, repartitioned, tried without SD card. Same problem. Also i'm only using the nand method. I've never tried the nativeSD or dataonext methods.
