Who is your service through? Maybe that you have to contact your service provider and have them re-activate the phone.

Possibly you've lost your IMEI, Check dialing *#06#.
You have an EFS backup?

EFS/IMEI is the "identity" of your phone and each phone has one imei.. if you lost it by flashing your phone you can only use your phone without network.. please make sure that you make an efs backup in the future.. but how it looks you have not lost your imei

You must have an IMEI Sticker on the back of your phone, look if both IMEIs are similar
Need to contact your service provider

Sorry friend.. You erased your imei partition. I did the same thing on my XT1543 four months ago, and until now, didn't find solution. I am using it as a tablet.

I wanted to be "smart" and taped "fastboot erase all" instead of doing it more than once "as it should be done". Guess I erased my IMEI too (on XT1541). Hope someone will come with a solution like those for MTK devices. Also using my phone as a tab/mp3 player.
Thanks

I got my cellphone signal back. Up to now, I can make and receive calls and SMS, but not connect on cellular data network. I flashed brazilian radio/modem.
If your IMEI is 0, you don't have any real option but to have it repaired. You should contact Moto customer service, there is nothin you can do to restore the IMEI to your device.

if u can register into a cellular network and send/receive SMS that means that u changed ur 0 IMEI. If i quite understand, this binary file that u flashed into your device did that task (of updating IMEI) ?
Can u give put the link plz?
Thanks!

Repair means writing a new IMEI in the device NVM.
As it was written/deleted the first time it can be refreshed again, just need to find the IMEI @ in the NVM (quite easy to say u'll tell me).
Do you have any idea how much Moto customer service charges that ?
Thanks
Hello bro idk if it's useful but u can use Xposed Framework's "IMEI CHANGER" modules.. Maybe those help..! Also try flashing modem images again..!

Thanks bro! The thing is that i'm on Marshmallow that cannot be rooted yet, if u got a clue on how to root it please let us know!
Does flashing the modem allows to change the IMEI ? is there a trick like hacking the source of the modem image and compiling it with a specific IMEI ?

If you flash modem files for your device , you will get back your imei and baseband, I already got by this.

Has anyone found a way to restore lost IMEIs?

I had the misfortune of bricking my OP8 a while back and ended up having to use SMT mode on MSMDownloadTools. As we all know, this will cause you to lose your IMEI numbers. They return a value of 0. Has anyone come up with a solution to restore the IMEI numbers without having to mail their phone in for repair?
U fixed?same issue

Again, this is why you don't illegally change your IMEI. Now you're likely stuck with a dead brick of a phone because you can't switch back the IMEI either.

Question How to restore IMEI + mac address?

Hello!
I wanted to change my MIUI version from global to eu, so I installed TWRP and flashed the rom. The problem is that somehow while doing this it wiped the IMEI, and wifi/bluetooth mac address. (so it doesn't see sim cards, and wifi networks)
Is there any way to restore the factory IMEI + the mac addresses? (I have them written down, and on the box)
And how to make sure that I don't wipe these things again?

Seems so. Don't know if it can even be restored or not if you have backup.
And if I haven't backed it up, is there a way to download it? Or is there any other way? Or is my phone broken?

No way to download it.
No legal way to repair it.
Warranty does not cover to repair it free of charge.
Broken modems.
