hey so i read that I should backup my imei but instead backed up my rom in cwm recovery then flash galaxy mod. it worked for 10 mins then switched to 3g then stopped getting a signal and check the imei and it said 0 so i restored back to stock and the imei went back to normal..then it just said 0 again after a while so i restored it again and its back up. anyone else have this same problem?

this is a known issue with AT&T. not only the S3 but HTC's One X and several others as well. i would imagine the problem is based on network location. you could try powering down, removing the battery and sim card for a few minutes and then clearing the data and cache in the phone app once its powered back up. otherwise, give a call to customer service. cheers

Ahh right. I forgot my dad had that when he had the s3 and he traded his phone for an iPhone..lol. I panicked and thought it was because I rooted my phone so I flashed stock with Odin. Guess I'll root it back and backup my efs folder this time lol

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.

Those darn s3's haha Lol. I don't get why it seems like restoring a nandroid is temporary but going back to stock with Odin erases the problem. I don't even know what I did wrong while flashing. I basically read how to root then started flashing things.
