imei problem

flashed a ROM today and it was working.. then it rebooted itself and I changed the kernel.. my imei lost...was using that kernel for long..I had a copy of efs from cm10.1 ..copied back ..set permission.. imei is correct... same as on back of the phone.. but no service ..any help... urgent...
Guaranteed method for IMEI restore is flash back to stock GB (no bootloaders), flash Corn kernel to get CWM, repartition the phone to match what you had (CM10.x, flash twice the same file), then restore your OS backup. You don't need to reboot the phone or setup the new CM installation, just restore your backup right after repartitioning.

Are you sure your imei is damaged? Try going to the recovery and factory reset and wipe cache. then flash stock rom maybe it will work. Hope this can help :fingers-crossed:.
***Additonal: Did you make a Nandroid Backup or any backup at all? Try restoring it haha :good:

Yup my baseband also became unknown after flashing custom rom through twrp but I downloaded the firmware and flashed it through fastboot but it was still not working so I read somewhere to remove the Sim before flashing and it worked you should try it too

HELP with EFS backup. Imei 0 and Baseband Not Found :(

First of all, I am an Argentine using the google translator.
Hello, good evening, I urgently need help to solve the following problem:
I have a moto g5s plus, xt18000, with android 8, to which I apply a custom rom HAVOC-OS-v3.5 TEN [10.0] - [SANDERS]). As God commands, backup the EFS folder with TWRP and apply the ROM.
The rom worked wonderfully, but it had no mobile network. Yes IMEI.
Perform the restore from TWRP, but it remained the same, without network, but with IMEI.
I went back to a stock 8 to see if I got the signal back. In addition to not recovering it, I LOST THE IMEI and BASEBAND.
Install a stock 7 and nothing. In all (in 8 and 7) install twrp and restore, but without it working.
And just in case I googled EVERYTHING, in ALL languages.
It gives me a lot of anger because I have the blessed backup of the EFS folder and it does not work for ANYTHING.
I know there are many posts on this topic but in none I found a solution, or guide.
Can somebody help me?
Thank you.
EDIT: In fastboot I Have my ORIGINAL IMEI. But in android is 0.
Hi maurorisuenio, i had the same issue flashing evo x rom on my wife phone. I spent almost 1 day to solve the problem, i'll try to give you my step to step guide, it worked for me.
- from custom rom flash back to stock rom, i used RETEU version 8.1 (i don't know what's the south america stock rom), on xda is full of thread "how to flash stock rom"
- flash custom recovery 'cause when you flash stock rom it repleace custom recovery with original one.
- now restore your EFS backup
- boot the phone, you should get back your IMEI but still no network signal
- flash the custom rom you want wiping system/data/cache just to have a clean install
-reboot your phone.
As i said it worked for me, hope it's ok for you as well.
Download the latest stock firmware and flash it in fastboot mode and remove sim before flashing and after phone boots insert sim, you will get your signal and imei back
