Hello.

As You can see from Software log, phone's modem part is damaged:

SW version: unknown
HW Modem: unknown

This can be Software (modem firmware or EFS is damaged, or You have written unsuitable firmware) or HW problem.

You should re-flash the device with different firmwares one by one and check, whether modem is correct (not Unknown). And only then (when phone's modem part will be correct) perform "Write Cert" operation. It is not possible to repair IMEI, if phone's modem part is damaged.
