I previously had issues with my GT-i9300 using a stock rom where it wouldn't boot past the Samsung screen and in recovery mode it was showing an EFS mount error. I managed to fix it with a file I installed through Odin. I then installed CM through the installer and it all worked ok other than my cellular access. I then installed a stock rom I found and I could see the mobile networks but still didn't get a connection. I then installed cm-10.2.0-i9300 but I still have the same problem. Now I can't search for any mobile networks and neither is it connecting to anything. I've tried putting it into Airplane mode and rebooting but that didnt work either.
I installed GetRIL and it shows I have baseband and RIL mismatch, but when I install other RIL's through the software, it still doesnt fix the problem.
Can anyone help!?!?
