yesterday I reset my phone to factory definitions and after it rebooted IMEI was missing (invalid IMEI). I tried to access the Engineer Mode -> GPRS to write it again, but there's no the button "Write" to add IMEI.

PS: My phone is not rooted, can you confirm me, if that's the reason I can't add the IMEI The phone is a MTK6577 Cortex-A9 dual core

Thanks in advance.
