Hello, I used Matt's all in one utility to root my XT912, installed Safestrap and then CM 10.1.3. About a week ago, my phone stopped connecting to LTE. I tried installing different CM ROMs, searching the web (*#*#4636#*#*), setting the mobile data to different settings, etc. I have another RAZR MAXX (stock) that works great with LTE. I believe the issue may be with my baseband version: Rooted Baseband Version is: CDMA_N_05.21.00R Stock Baseband Version is: CDMA_N_05.21.00R LTEDC_U_09.1D.00 After searching for an answer for days, I reinstalled stock with the all in one utility. Unfortunately, the issue persisted with stock (baseband CDMA_N_05.21.00R ). I have searched for ways to flash basebands, but the information is limited. This is horribly frustrating. Any help is GREATLY appreciated.
