Mobile internet does not work to failure . Prior to the first number flashing Inet worked with enthusiasm. But after put CM 11 , then it stopped working . Sometimes appeared icon "E" and "H" icon beside the network signal . But even when these letters were , the Internet is still not there . In the general information number " data transmission mob. Sharing " is eternal " connection " or " connected " , but an Internet or not. Then moved on to the same CM 10.2.1 because thought because nightie , and no internet . Reflash radio module , firmware flashed correctly ... But an Internet and has not appeared.
What could be wrong?
