If you already have the firmware then you can do that. If u don't have.. Just go to recovery mode. There 'll be an option for enabling cp logging Just enable that. Your problem will be solved

Qulacomm USB drivers should be installed on PC first. Native Sumsung drivers should be unistalled.

1. Install phoneutil.apk (attached)
2. Install QuickShortCutMaker
3. Run QuickShortCutMaker -> find PhoneUtil -> expand it and choose "com.sec.android.app.phoneutil.SerPortUartUsbM SM89 60" as a shortcut. Shortcut will be placed on Home Screen
4. Disconnect phone from PC.
5. Run Shortcut. Choose MODEM ->Qualcomm USB Settings -> DM+MODEM+ADB -> Ok.
6. Connect to PC.

Samsung_device. (CDC composite).
For these devices i manually chose QC serial driver:
Manual Driver Installation -> Chose preinstalled driver -> Ports (COM+LPT) -> Qualcomm Incorporated -> Qualcomm HS-USB Diagnostics 9004.
Do it for both unknown devices.
