Help!

Hello guys!
Six months ago I bought a used note 8 SM N950F once I tried to install another rom (custom one) after backing up the whole mobile by twrp, after installing the rom, the phone couldn't detect sim cards and imei, when I returned to the backed up rom everything were fine.
I searched for my phone's imei and the result was these imei numbers belong to another samsung device, samsung ace I think.
What is the problem? I can't use any rom exept the original stock rom which already installed to this device, help me finding a solution to install another roms with working sim cards.

Could I make an EFS back up and use this back up for the other rom?

Yes i think it can be done
... Quite a few tutorials to do that online. Go ahead and Google it.... I have not done it myself. So i will not be held responsible if anything goes wrong. But it should work. All the best.

You need to return that device immediately it's never going to work you cannot use ANY efs folder from ANY other devices and even if they do flash they will not work!! Stop wasting your time and send it back!!
