Hello, 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.
