Hello.

As I see from your Software log, there can be the problem with phone's EFS:
Unfortunately, Repair EFS is currently not supported for this device, we will add Repair EFS feature in one of the future Software updates. Now try to re-flash the phone with another firmware, make Factory data reset, make Unlock, Repair NVM and repeat the Repair IMEI operation once again. Post here the result.
