Imei changed, is my phone for the bin?

Hi all,

I flashed my phone and didnt something stupid. Anyway to get to the point my imei has been changed, my edp folder whatever its called im guessing is long gone or damaged.

I don't get signal and spent hours looking online, nv gen etc but thats for american so doesnt work.

without the edp folder whatever its called is there a way to restore imei or is it for the bin?

Probably not worth sending to samsung as they will charge a fortune.

thanks
