SIM not found & lost IMEI.

Jul 3, 2014
I have a problem with my Mi3 device.
After a normal restart the SIM card is not found, i try to made a factory reset but the problem remain.
If i start with OTA update, the Service ask me Xiaomi data access and if I insert my date a error Message appear with "no valid IMEI" information.
If I try with code *#06* the error "invalid IMEI appear".
What soluztions? :(
Think you.
