Editing or flashing IMEI's is illegal.
If its a legit issue of it being wiped, you'll have to send it in to the manufacturer or a service depot.
We don't discuss such topics in XDA. Sorry. 👍

I'll add that the only success I've seen restoring an original imei , without a service center giving it, is buy restoring your EFS folder. If you had it backed up. Most people don't tho.
