Re: imei problem
I recently experienced the the same issue but with a different rom. I did a clean install, everything booted up and seemed to run exceptionally well. After 30 mins or so I lost my data icon and signal bars disappeared all together. My imei showed 0 along with eri version and serial number. I panicked a little bc I was at work without access to my laptop, booted into recovery and restored a BlackJelly cwm backup. Luckily everything was seemingly normal again after that and going forward has been fine. But a couple of months prior I flashed the wrong recovery.img and completely corrupted the efs folder. None of my cwm backups worked at fixing the imei, eri and serial. Thankfully there is an amazing guide in our development forum that addresses exactly how to fix this.
