I have been trying some new ROMs on my I9300. During the process I installed the S4 Revolution ROM V11 Beta 2. The ROM works but is quite buggy and slow so I decided to flash it back to Omnirom. However since then I get no network connection for internet or calls. I get the same with the stock firmware also. If I reflash the S4 Revolution ROM I only get network access if i select to install the "XXEMG4 Modem" on setup.
I have tried wiping cache, formatting partition and reinstalling other ROMs but still no luck getting the network back - Only on S4 Rev ROM.
Is anyone able to offer some insight in to this?
