And if you don't have a backup, just flash the factory images a gazillion times until the imei comes back

I don't have backups and give me another way to restore imei.No gazillions times.

Where does the efs folder can be found? I've searched for it in rootExplorer but no way to find it.

You don't need to back it up. The Nexus devices don't have the same problem samsung has.
But if you want to anyways, here:

The loss of the imei can usually be fixed by flashing the factory images.

Flash the factory image. If it doesn't work the first time try again. It's your only hope. I'd give up if I got close to a gazillion time though
If that doesn't work I'd RMA it if you can.

That's odd... Which lock screen mod did you try to install? (make sure it's compatible!)
My advice would just be to Odin it. It's really strange that a nandroid backup didn't take care of it
Did you change the kernel at all?
That pop up looks like one of the things you can do on developer options.

Thanks guys. Just let sprint. They tried fir 2 hours to makes that message dissappear. Flashed new software several times. The tech finally gave up and ordered me a new phone. She said it was hardware related.

Updated to 4.2.2, get no signal now

I restarted my phone, reinserted the Sim tried everything I'm still not getting signal, anyone have this problem?
Sent from my Nexus 4 using xda app-developers app
How did you update? OTA, flash ROM, etc...Have you tried SIM in a different phone? Could be a bad radio? What does your baseband say in System> About phone?
It was the official OTA
I never updated because 4.2.2 killed LTE but then I did anyways
My baseband says unknown
Edit: the 4.3 update came, I tried updating but it said error half way through wtf!!!

See this a lot, updating killed the radio. You probably don't have an imei number either.
Try flashing an official factory image.

Don't waste time with doing anything else. Flashing the factory image will not get your imei number back and without it, you will never get a signal. When you call to RMA it, be sure to tell them you lost the imei number during the upgrade process. They should have plenty of lost imei cases in the system already.

Regardless it's safe to just flash the factory update, then see where you can go from there if all fails use that as your last resort

Normally I would guide you on how to fix, but since a phone shop messed it up on you it's not up to you to fix, why should you risk your warranty cause of their mistake?, bring it back and demand they fix it ASAP for free.
I bought the phone when I was in tour,more than it the knox had triggered it to 'warranty bit 1'.
Please give me a soulution !?

If no efs backup is available your pretty much have a brick.. It contains your imei sig.

Not strictly true. Lots of people have no efs back up and can restore easily.
Number 1 - there's a fore script that rebuilds the partition, which the note 3 can do.
Number 2 - Your imei is stored on your box for the device to, with a little bit of adb trickery you can restore it fine.

Yer arse, if the efs is empty then your pretty much ****ed without a backup... That imei number he has is a generic default when the system can't find the original.. Edit: however I've no idea if such a script /program can regenerate the original imei number.. I had the same problem on a galaxy S1, wiped the phone, reflashed a custom rom, bang no imei.. Had a backup of efs and had it working again, phew. Reading about the imei was a nightmare..

There's plenty of threads where people have restored efs and lost IMEI and serial numbers. - things have changed significantly since the S1 days....
amancools there is numerous threads around, search for them. I'm on my phone and searching for links is annoying.

Can you get to stock recovery and do a factory reset? If you really screwed up your EFS folder, and you don't have a backup of it, you won't be able to make calls ever again, and you IMEI number is gone. You'll have a 5.7 inch media player.
In such cases, a Samsung Service Center trip might be your only option.

Download this put in AP/PDA in odin then flash.
Just to note to people replying in this thread, this guy already has a thread open about this and has tried all the script fix tricks.

If you see this while booting into stock recovery, that can be ignored as we don't use the stock recovery for anything other than ota.
If you see this during normal boot, you would have to Odin back to stock and start over.
Well I can't boot into recovery I get this all the time
