After the phone was restarted, then I did unlock again, and then the software downgrade the modem again like that. I tried many time, keep downgrade the modem, but the modem downgraded already Phone version: N960USQU3ASJ1.

It is a bug with the vesion 39.6

Please let me know. Thanks
Thank you for the report, we checked it. Bug will be fixed in the next update.
