[Q] My imei is blank. Backup missing as well. - ONE Q&A, Help & Troubleshooting

So I made a backup and promptly flashed a new rom as soon as I got my OPO it hasn't even been activated yet. When I went to activate it I realized my imei number was null. I looked for my backup but I must have deleted the backup somewhere along the way. Is there some way to restore this. Like if I flashed the stock image would it fix this? I saw another thread for fixing a corrupted EFS but is that the same thing. I'm sorry I don't really understand much of this stuff.

Thread concerning corrupted efs is where you need to be.

Changed IMEI

Hello XDA!
I've got the I9105P version, and after I've flashed a few rom's, I saw that my IMEI is changed to 0000000000. Although, I can make phone calls and have data connection on my phone. How could I restore my original IMEI? I have it on the back of the phone, with the serial number along.
Please help me!
Thank you!
Hello,
You can try and restore some backup if you have one, It should solve the problem.
If you have a EFS Partion backup, would be better.
Meanwhile see this 2 link:

I hope you will solve it.
Best regards,
Thank you for replying, but I already did what's in the first tutorial. The problem is that when I flashed a custom rom, I didn't knew that I have to backup EFS files(noob). Now, after reading and reading, I know that this is important. I reflashed my stock Rom 4.1.2 and nothing, and then reflashed 4.2.2 ultimate update from sammobile, and still nothing. Is there any other way in restoring my IMEI?
Hey guys! I search a lot in the forum, but unfortunatelly, I don't have the NV Data files in my EFS folder. I think the only solution is to get the phone to a gsm service, that has a Octopus Box.
If you think that I have a solution without this, text me

[Completed] T-Mobile Note-4(N910T) EFS Folder empty, when in stock can place calls and use LTE

I have a Note-4 T-Mobile variant(N910T), I have been using Xenon HD and then CM 12.1. After a while when I wanted to go back to stock, and when I flashed stock rom back, the phone was really laggy at first and during setup, there was a popup which said that Factory mode is enabled and I have to switch back to User mode before using it and after a few seconds it disappeared, this happens every time i reboot while in Stock Rom. Somehow after a few minutes, I get the WiFi on again but the keyboard gets stuck after a few presses and phone gets real laggy. After the setup I googled the problem and found out something regarding the EFS Folder, so I rooted it once again and installed ES File explorer and went into EFS and found that it was empty. I tried placing a phone call and it went through and I was also able to use LTE, but when I went to about phone to see IMEI, i saw that the IMEI was wrong, I even tried to setup fingerprints, but it kept saying me to reboot as something was wrong with the fingerprint sensor. Now the weird thing here is that when I am in a Non-touchwiz based Custom Rom, I do not find any lag and the IMEI is correct. I have tried these things already:
Going to EFS and switching Factory mode on, but as i told EFS folder is empty.
Backing up EFS from the custom and restoring when I'm in Stock.
If anyone knows how to fix this, could you please help me?
Thanks!

Restored Old Phone To New; Now Can't Connect To Network?

Hey all,
I restored a backup of my old phone made in TWRP – a full backup, including Boot, System, Data, Cache & EFS – onto a new D850 I got. Both the old phone and the new one were able to connect to AT&T before this.
Now the new phone, with the restored backup from the old one, displays a network searching icon indefinitely upon reboot.
Any thoughts as to how to fix this?

Why did you restore a EFS back from your old phone to your new one? Unless you backed up the EFS from your new phone there may not be a way to fix this. EFS Is different for each phone you should never restore an EFS from a different device.

My *guess* is that I should not have overwritten the new phone's EFS with the old phone's? I think I backed up the EFS of the new phone before doing so; will restoring it fix my issue? If not, how screwed am I?

See if you have a backup of the new phones EFS try that and report back. If not it's pretty much a WiFi only device.

I restored the new phone's original EFS, and all is well.
FWIW, my reasoning behind flashing everything from the old phone to the new was that is what it said to do in every guide I read about transferring from old to new. I didn't realize EFS was supposed to be excluded; I didn't realize the EFS from one phone would be incompatible with another
In any case, crisis averted – thanks for the confirmations along the way

It's not that the EFS is not compatible. But the EFS stores info like IMEI etc. you can't have two phones with the same imei. Each EFS is different. When restoring you don't have to restore every thing though. I'm glad you had a backup! As without that it pretty much would had been an wifi only device. Your very welcome .

Lost imei after factory reset and root

Hi guys,
I have a slight problem here, I was using my rooted with magisk and running lineageos17. Unfortunately, bluetooth wasnt working so I reverted back to stock, which fixed the bluetooth problem. I tried rooting the thing then with this method:
https://www.xda-developers.com/install-android-oreo-samsung-galaxy-s7-exynos/
Unfortunately though, this killed my imei. I tried restoring my efs partition with twrp; even tried reflashing the stock firmware, all to no avail, my imei is gone.
Is there any way I can restore it or have I turned my phone into a fancy paperweight now?
Would be cool if anyone could offer me some help,
best wishes,
derelektrischemoench
// edit: I managed to get twrp installed and was able to restore my twrp- backup which i had made before this whole endeavour and voila: the device is back online, has an imei and is able to connect to a network. Hell yea. Thread can be closed, I guess.

The whole EFS/IMEI Partition is messed up. In need of urgent HELP!

Hey guys,
It's briefin here. So yeah long story short, I recently restored a TWRP backup file of the EFS partition from another OnePlus 7 Pro. Now everything else seems fine but unfortunately my whole IMEI is just messed up (It's showing 0(zero). And that's why phone 's network signals isn't working anymore. Also I don't have any backup of my original EFS Partition. So is there any way, that I can rewrite my IMEI to my device?

Buddy I'm kind of in the same boat. I tried a sim unlock I was directed to and lss my backup became corrupted and gone forever. It's been a nightmare. And so far not looking any better or at least for me. But if theirs a way I'll find it
