SW version: unknown

HW Modem: unknown

means, that there is a problem with modem part of your device. This can be Software (modem firmware or EFS/Security is damaged - most likely, or You have written unsuitable firmware) or HW problem.

If You have an original EFS/Security backup for this device, write it and check baseband. If You don't have such backups for this device, perform "Repair EFS" operation and then re-flash the device with proper firmware and check, whether modem is correct (whether baseband is not "unknown"). And only then, when baseband will be correct, try to perform "Fix DRK".
