How do I recover/enable IMEI number?
I own a Sony Xperia E4g. It is rooted, the boot loader is unlocked and I've recently started experimenting with flashing custom ROM's and other things related to that. One morning I noticed my phone had no network coverage/signal and wasn't detecting my sim card. The setting that provides information about the phone, where my IMEI number was, is now a blank space.
How do I recover or enable the IMEI number so my phone has network/signal coverage and can identify my sim card again?
Any tips or suggestions will be much appreciated.
