I flashed a TWRP MOAR backup, 1 day after that, my carrier blocked my phone, they said the TAC (first 8 imei's numers) was from another model, a samsung galaxy prime (I have an SM-N920P) so they blocked that imei. The point is I didn't do anything to change that imei, I just made a full backup and restore (including EFS folder). Any way to get my original imei? I already tried flashing the backup again. I don't have any other copy.

Efs and relationships with Kies update.
Ok so another weired behaviour from efs comes to picture.
Recently I have observed many cases with failure of firmware update with Kies due to unknown csc (xxx), even though dialing *#1234# showing everything correctly.
Now I have observed this when you have corrupted EFS, height is that your IMEI still will be correct and no network issue. But you will have only corrupted product code.
Again
This kind of issue happens if you restore your EFS backup which you have created on older rom (before me6) on latest ROM (ME6 or later).
In such condition there won't be network / IMEI issue, but you won't able to update on Kies.
How to confirm your product code corrupted ?
Install check fus or sammobile app from play store and this will show product code 'inactive'
Remedy :
You should have EFS backup which should created just after upgrade to me6 or later.
Restoring this backup also restores your product code too and you will able to see product code again on above said application.
If you have EFS backup, which you have created on older ROM only then you can reflash Older ROM. this will erase IMEI but with your older EFS backup restore it. Now check your product code, it should be appear correctly. You can now upgrade to latest ROM and make new EFS backup. which you need to restore on newer ROM only.
I have tested myself restoring both EFS backup and above said is conclusion.
So make efs backup on both firmware (prior and post me6) and restore accordingly if you want to keep Kies update possibility intact.
What if don't have any EFS backup and Product Code is missing?
Let our elite dev to respond if we can restore it with ?Hex code or anything else, Untill that

Im installed a custom rom (CM13 6.0) For My Galaxy J7 (SM-J700F) After that my IMEI had changed and i can't use my netword and calls again .

I think if you flash the stock rom your old imei will be back
If possible Plz Find another J7 which have custom recovery and backup his efs than put it folder from his phone to ur phone In backup folder than restore it...
I think its backur network....
Note: Do it first before Flash any rom... Backup all files with twrp
Same Problem here
Hi I'm using the Galaxy J700H phone its like 2mos old, and have the exact same problem, so please can someone help? My problem is, I think also is my IMEI number? When i dialed *#06# on my phone my IMEI is 350000000006 and FTW that's not even my IMEI anymore, I have the original IMEI number here backed up but i tried everything, step by step. But sadly nothing worked out. I used this sim card in all of my phones and lastly when i wiped out my phone and flashed custom rom in it, then this happened, then i decided to flash the stock rom that has been downloaded from the sammbobile.com website, after that nothing happened. My phone always displays EMERGENCY CALLS ONLY.. pls help
Hey all,
I had an S7 edge (G935F) since launch. I took a full backup of it with TWRP (EFS included) then had it replaced with an identical phone (G935F). I stupidly restored the backup including the EFS from the first phone. This is now causing my new phone to not register on my mobile network, and to say "unknown" for IMEI and bootloader.
I do know what the IMEI is supposed to be for this new phone, but I don't know of any way to set it. I also never took a backup of the new phone so I have no way of recovering its EFS.
Any help appreciated.

Hi
Check here:

So i am trying to restore the imei number of my phone, it is currently 350000000000006 which seems to be some default thing. I am trying to use z3x samsung tool pro however during the process it gets stuck at checking Super User right...
Does anybody know what the problem is or if there is an easier way to restore my lost imei (i don't have an efs backup)
thanks
I recently purchased a new S7 and promptly attempted to restore my old S7 backup onto it via TRWP. Not realizing my new phone was Nougat based (old phone MM), I was unsuccessful and have since attempted several firmwares to restore my new device. Finally got my new phone to work, but I no longer have an IMEI number on it, and the Serial Number matches my old phone. Any idea how this could've happened? And, more importantly, is there any way to restore the original Serial Number to the device?
EDIT: Spent the day flashing firmware but I always need to flash TWRP and then install no-verity-opt-encrypt file just to get the device to work. I have no idea how i did it, but it seems impossible that a Serial Number could get changed on a phone.
Guess when I restored the EFS partition to the new device, it changed the serial number. Easy fix to change it back in the EFS folder. The IMEI was quite the challenge to restore from unknown to 000000000000000 and then finally the proper number. I guess this post can be deleted.
