Hi, in what condition is the status of the service mode of the IMEI code in addition to being null and the radio modem of the service mode going on the keyboard do this code * # 0011 #.

If you only have the problem of the IMEI null code you should write the EFS folders again and see if the IMEI code returns to default, then try to write the IMEI certificate

Below is the link where to download the EFS folder:
