Hello.

"Write Firmware" is currently not Supported for D820 phone. What version of Android has the phone at the moment?

Unfortunately "Repair IMEI" operation is not adapted for D820 phones with Android 5.0 firmware.
On your own risk You can try to re-flash the phone with Nexus Root Toolkit, or in the way described here: https://developers.google.com/android/nexus/images
