Koskoz, Feb 19, 2016 : Hi, Since this morning I'm not able to send or receive call. SMS and data is working correctly. I've tried rebooting the phone, removing the SIM, another SIM (on which the network couldn't been found), wiping the cache but nothing works. When O click on a phone number in the dialer app the phone application shows up, no phone number is dialed and the message "End of call" is shown. I'm lost, what can I do? I see two solutions: wipe all the data and get the phone back to a factory reset, but I don't want to (it's so boring) or reflash the ROM but I don't know how to do it.
