Default [Q] Fake IMEI after flash & no backup available

Hey guys,

I have a very big problem. I've got a fake IMEI after flashing a custom rom and I can't find my IMEI Backup anymore.
I tried many solutions but nothing helps.

Device Info:
Samsung Galaxy S4 GT-I9500
Country: Vietnam
IMEI:004999010640000/01 (I think it's a fake IMEI, so it's useless for everybody and i can post complete no.)

Tried Fix:
Downgrade Stockrom 4.2.2 from Vietnam
result: No Fix

After Downgrade, Upgrade to 4.4.2 Stock from Vietnam
result: No Fix

Flash some other Modems (not all in threadt)
result: No Fix

EFS Restore with "EFS Professional"
result: No Fix

Copy EFS folder to Windows & edit with HxD-Tool (nv_data.bin & serial_no)
result: No Fix

I hope you can help me. I know there are very much threads in XDA but nothing works and most threadts are very old.
Maybe i'm to stupid... ~.~

Ps: Sry for my very bad english. I hope you understand me.

Thank You

Unfortunately you cannot get the help you are looking for on xda. The way you need to fix this is not legal in most places in the world. So the discussion of this kind of information is not permitted on xda

Sent from your phone. You should be more careful where you leave that thing.
Do you want insanely better battery drain when your phone is idle? Check out this thread!
