Recording IMEI on an idle Android phone through engineer mode

Question

Yesterday I reset my phone to factory definitions and after rebooting IMEI was missing (invalid IMEI). I tried to access engineer mode → GPRS to write it again, but there is no “Write” button to add IMEI.

PS: My phone is not rooted, you can confirm me if for this reason I can not add IMEI The phone is a dual-core processor MKK6577 Cortex-A9.

Thanks in advance.
