I have a Razr HD XT925 from Claro Puerto Rico on AT&T and I have not been able to get 4G/LTA. Some people tell me my phone is not compatible other that I need a different firmware modem.
I tried flashing Rogers modem from Canada but it did not work. Only get H+ data services with original Claro Firmware and the modified one with the Rogers Modem.
Can you please help me with my problem?
Thanks in advance
