I just flashed the stockMod 4.3 ROM and can't receive or send text messages. I followed the instructions. Before I installed the kernel I rebooted and everything seemed to work such as 4g and wifi. However in the interests of following the instructions I installed a kernel and the phone wouldn't boot up afterward. So I flashed the ROM assuming there must have been a kernel in the rom already and the phone appears to work fine. Except no text messages.
