Imei null huawei CUN-L03 confused:

Hi friends from support, i tried unlock this model using gcprokey mtk option, but after unlock it says failed, restarted the phone and imei blank on phone, now obviously it doesn’t detect any sim card, the only one backup that gcpro made is security backup, is there any option to write this file back to phone??, please help me to restore imei from this phone.

Thanks in advance. :Best regards
