No panic. It's not
I mean 99,9 % not
expect answers from me about IMEI (and Network Unlock).
Because tooo much trouble
I'm from Germany.
I have no idea about other countries law.
But I'm pretty sure that NOT
every one who need IMEI repair is an thief.
Also Software accident can lead to IMEI lost... or some Firmware Modifications, or some Commands... or Tools...
I have no idea, why manufacturer not really
protect IMEI. Maybe 1 Chip for IMEI, not eraseable
... for instance like oneNAND and RAM in Samsung CPU, but only not rewriteable. Also funny. IMEI on removeable Label...
