Im on Resurrection Remix 5.1.5
My mobile connection has being going on and off more and more frequently and is now dead. WIFI is ok.
I have done a number of things to troubleshoot this issue, but nothing seems to help.
Now all I see is the empty, black triangle where the bars used to be.
This was done while I momentarily had mobile connection:
I have turned mobile network on and off numerous of times.
Location doesnt matter. Right now Im in a well covered area.
I have reinstalled modem. Im on xxms4.
GetRIL tells that modem and RIL doesnt match, so I tried switching RIL. That disabled mobile connection completely.
I have tried reinstalling OS.
I didnt check while it worked, but now it turns out that I dont have an APN. When I enter a new (description from my carrier) and press "save" it doesnt save at all.
After mobile network died I disassembled the phone to look for bad connections etc. It all looked fine. Phone works, but network is still dead.
Could it be the sim card?
