I just rooted using No Trip Counter method. My IMEI is still intact but I don't have ERI version. I read about IMEI being lost but what is ERI? Sorry, noob question and probably noob mistake for not backing this up. Anyway to get ERI back?

EFS problem hindering flashers?

Recent stability update is not allowing the flashers to downgrade or limited to only roms with particular modems as it is causing to corrupt the IMEI.
Though our clever developers have found many solutions it has become a hindrance to many of flashoholics like me.
What do you think? Can there be a permanent solution to this? and most important why Sammys have done this. I do not think this is some kind of bug. It is done on purpose,like preventing people from frequenting flashing?
what do you say?

I agree with you, efs problem and partition table corrupt are such problems which make people to think before flashing

I am not flashing any rom for the moment.
Do asop roms suffer from efs problem?

After an update my IMEI has changed from what is under battery cover to something like 004999xxxxxxxxx after which I can't make phone calls any more , after checking I've discovered that the EFS file doesn't contain the IMEI anymore, when happened this my phone was not rooted so obviously I have no backup.I've flashed back the original ROM many times but it's still the same.
Do you think there is a way to find a solution to this?

Please give detailed description of what happened like which was previous rom and which rom you are now on and trying to flash....

Latest update is not allowing the downgrade of modems, so please reflash the nordic rom so that atleast you will have your IMEI back. I was on ARHD 17.0 , tried Omega rom which is DME6 and reverted to ARHD 17.0. In the process I lost IMEI. So I reflashed Omega and I had my IMEI
NOw ARHD 18.0 is also DME6 and I can flash it but not below that

Ok will try it.

Just one question please,do I need CWM installed on my rooted phone to flash a modem?

We did try that a few times, it did not work. I was genuinely surprised as we used a Swiss stock rom that restored the imei number and network connectivity.

BASEBAND UNKNOWN, IMEI UNKNOWN, NETWORK UNKNOWN, No backup of efs

I have a Samsung Galaxy S3 AT&T (I747) phone, when I tried to install android 4.3 Stock ROM which I downloaded from a 3rd party website I Baseband, IMEI and lot others became UNKNOWN . After a lot of googling i found out it could be because of the efs folder. But I didn't have any back up of it. I downgraded my phone back to 4.1.1 successfully, but still the issue persists. I could not find any backed up efs folders online and none of my friends are using a s3 AT&T model.
Please suggest what else can I do? or if someone can help me out, provide me with a efs backup for efs professional.
Thank you in advance.

How did you downgrade to 4.1.1? I didn't think that was possible once the phone was running a 4.3 or higher bootloader.

I found flashable files for both firmwares which made the downgrade possible.

Are you sure the bootloader was downgraded to 4.1.1? Running a 4.1.1 rom on a 4.3 bootloader can cause the issue you are experiencing.

Yes, My mistake the bootloader and modem were struck at 4.3 even after the firmware downgraded to 4.1.1. So I again updated it to 4.3 and restored a qcn file i found online and it resolved my issue.

Glad you got it resolved. If you run into the same problem when flashing recent custom ROMs, you may have to upgrade the bootloader and modem to KK.
