You should be able to follow the instructions in this post: http://forum.xda-developers.com/goo...t/modem-nexus-5-flashable-modems-efs-t2514095
This has been confirmed (by another user) to work on the Moto X.

You'll have to flash back to stock KK4 (without bootloaders) to restore it. Once on stock, make a backup of your efs folder. Get back up to Captivating and if you get the error again, simply replace your efs folder with your backed up one (with the right permissions) and reboot. Should be good from there.
P.S.: There are plenty of little guides explaining how to recovery from IMEI error/lost. Use the search next time
Thanks for answer, is it safe to modify EFS folder? in case of anything goes wrong how can i restore the original state?
P.S.: Is this a general issue regarding 4.2.2 for this device or a rom cooking error?
Thanks in advance!

It's not a general issue, it randomly happens and lucky for you, it's easily fixable.
Yes, it's safe to replace the efs folder. Know that without it, you won't have signal nor data so you don't wanna mess with it. Going back to stock will flash the correct one on your device (which will fix your IMEI problem) and if you get this issue again, you'll have a backup of the correct efs folder.
Great! Thanks again for your answer!
Hi, I bought an unlocked galaxy ace S5830M a few months ago, and I rooted it as well so I can install a new ROM. I've read that I need to back up my EFS folder, but I found out it's empty. Is that normal? Do I need to backup anything at all if the phone came factory unlocked? I've looked for the answers, but couldn't find anything either here or on google that could tell me it was safe to install a new ROM. Any help would be greatly appreciated!

Hi All,
Totally new to the site.. was looking around for an answer but no much luck.
So question is how does backup ta works. I rooted the phone, and used the tool and now it has a backup. which is only 177kb
And does this mean that, later if i decide to go back to the stock rom, I can just recover from this backup ?
Thanks heaps for your help
Pavi:silly:
ounds like you backed up the cache only..?
What backup tool you use?
CM recovery or TWRP?
this

Compressed it can be 177KB, but that can be different per backup since the actual content isn't static. Extract the ZIP and check the size of TA.img, it should be 2MB (2048KB) round. Next time you better ask it in the Backup TA thread. Only read this one by coincidence .
yes!!

I'd say yes, but it's personal preference really. If you'd happen to lose your EFS, then you're screwed because it contains your IMEI, MAC Address, Wifi MAC Address, etc...
If you flash a lot of ROMs I would say yes, but if you flash zero ROMs or very few, then I would say it's not totally necessary. It only takes one bad flash to ruin your EFS.
No one replied so I figured, why not?

OK thanks. Would assume it's somewhere in an advanced setting somewhere? Don't remember seeing it in the regular backup part

Just do a regular Nandroid backup in recovery via TWRP and there is a check box for the EFS partition. Check it along with anything else you might want to back up at the time. Make sure you are on the latest TWRP version, otherwise you may not have this option.

Not a problem. Sucks that you didn't get an answer until now though.

I wasn't the one who originally asked the question I just saw something about needing to backup something. I'm kinda paranoid about backing things up. Few more things to ask. Do you back EFS up with every nandroid and just restore it with everything else, or do you keep a copy of just the EFS itself and restore it separately if something messes up?

I do a one time back of of just the EFS for each major android update, then erase the older version.
Like right now I have the efs backup for 5.0.2. When 5.1 comes to play I will back that up and then delete the 5.0.2. Just my preference

One more question. Can you make a backup of just the EFS partition and restore just that partition or do you have to restore a complete nandroid of the whole system? Thanks I'm sure this is all basic stuff to you but I seem to learn something new every day.

OK thanks. I'll make a copy of just that. Guess that means you can just restore that alone.
Hi everyone! I am a newby here. I just want the Efs backup from TWRP of 6.0 Marshmallow
Please anyone upload it. Thanks.
I'm sorry, but you can't use someone else's.

I'm having some problems with wifi/bluetooth mac address and want to try to format efs partition and then restore it
already have an efs backup made with TWRP but couldn't find the option to format that partition in order to fix any possible FS error.
Did you know how?
Can someone with a T-Mobile Galaxy Note 4 N910T3 that has a TWRP backup INCLUDING the EFS please upload that and give me a link. I screwed up my EFS and if someone with the same phone could please make and upload their TWRP backup (just with EFS box checked very small and not your data) for me it would be greatly appreciated. I know I will have to go into it and edit my serial # from yours, but it should get me back working.
Thanks
Efs backup from another device will never work because it's related to your phone's specific hardware.
You did big mistake that you flash backup and efs from old phone to new one that completely screw up your efs partitions and drk ( device root key ).
Sorry but you should make always efs backup from twrp in microsd card before start messing with phone. Cuz flashing always risky job.
Trust me odin or twrp will not going to help you.
Dont waste your time You should go to repair center cuz they have tools like dongle box to fix efs and imei.
They will write new cert files and restore your efs but i dont think they can fix drk cuz i see many drk damage cases but didn't see any working method unless changing entire motherboard.

Kies doesn't work with Note 4, Samsung Switch freezes. Odin works fine, but that is not the point.
I need a N910T3 TWRP EFS nandroid backup file from someones phone to flash it. That is what I can not find.
