IMEI Lost

[Ricardo2003]

Guys, I don't know how to fix this, I lost my IMEI after flashing aosp extended unofficial Oreo.
I have a efs backup but after restoring it, IMEI didn't change, don't know if my backup is bad or something. I know my IMEI number and it's saved in my laptop.

Any idea serves

I'd say backup all your pictures and videos and backups and stuff to your laptop and flash stock 7.1.1 again (the latest available). Then, in case it's still gone, try to update to 8.0. in my case this worked and... I didn't had a efs backup .

Same here, flashed the latest 7.1.1 Stock Rom with rsd lite 6.2.4 and imei was 0. Then i flashed stock Oreo update per sideload and imei was back.
