zoesky , Jul 11, 2015 : So here's what happened. I tore down my opo to replace the screen (I dropped it) All I did was move all the internal stuff to the new frame. The screen looks good and as far as I know everything works.....except for the cellular connection. The black cable lying next to the battery... does that not control the wifi, bluetooth and all that jazz? All of those features are working so it makes me think it's not a hardware issue, but a software issue? Could I be wrong? I read some posts that after upgrading to Oxy they lost mobile data connection... Some reported flashing the device worked. My sim is recognized, the APNs are there. I can see my number and imei under about phone...but the mobile is disconnected...I get errors when trying to connect automatically to network operator. Any direction would be greatly appreciated.
