A while ago I rooted my phone to at the time the latest cyanogenmod 10.1 update and it screwed up the phone. It took me a week to flash it back to stock using odin and get it back in running shape. But now whenever I try to flash it to a rom other than stock jellybean, it has the same problems as before, no service or data, no access to play store, and no imei or eri. I have it running stock 4.1.1 jellybean and it has access to play store as well as service and data. But the ERI and imei say none and 0. I would like to be able to get my phone to the point where I can flash it to aosp roms without losing data, service, or putting it into roaming mode. Any help on the ERI and IMEI issue, or not being able to root properly?
