[Q] Not recognizing simcard and no wireless functionality turns on
I flashed 10.3.1.e.0.191 ftf for my c6606 because I was randomly getting crashes of the system process and that was forcing my phone to bootloop. After installing this ftf I was still getting the same problem of the process 'system' crashing and the home screen wouldn't even load up.
Then I decided to download and install another ftf version 10.1.1.b.0.166. I can navigate through apps and all of the home screen but it is saying my simcard is not in even after I took it out and put it back in multiple times as well as rebooting. I also can't turn on any type of wireless connectivity(wifi or data). When I go to wifi settings it is just stuck on 'turning wifi on' and it never actually does so. I also can't enable mobile data either in settings.
Is there anything I can do? perhaps there's a better firmware that I should flash
