I'm using patched MG4 on resurrection-remix (4.4.2) after I lost signal because of stock 4.3.
Works well and no flaws so far.

in your case, what are the symptoms? tell me your IMEI and baseband...

You have corrupted your efs. Very hard to revive. Try flashing the original firmware via odin.
I flash the original firmware via z3x but same problem.
I solve the problem with z3x with some files.

Flash combination ROM can fix it. Or flash efs and nv_data.bin file with zx3
