Hello.

Try to re-flash the phone and then make Repair NVM. To finish the Repair NVM operation, please restart the phone via phone's menu (via "Power ON" key, don't disconnect the battery, this is important).

Also, look here:

Reflash with Octopus firmware, or with Odin?

@ maddriver13

Hello.

Try to do the next:

1. Install the latest Software version (Software).
2. Write the first Security backup, that has been created by Software before performing the Repair IMEI operation. This will return the phone to the initial state, in which the phone was before.
3. Read QCN from the phone.
4. Make Repair IMEI again.
5. Write QCN.
6. Write here the result.
