```auto
Enabling selective suspend ...
Firmware download failed.
Primary error code: 77 - Failed in streaming download stage.

Hi @jyijyi ,

I don’t want to use latest FW exe, so I choose “9999999\_9904609\_SWI9X30C\_02.33.03.00\_00\_GENERIC\_002.072\_001.exe” or “9999999\_9904609\_SWI9X30C\_02.33.03.00\_00\_GENERIC\_002.072\_000.exe” to upgrade FW to test it.

The device will be QDLOADER then disappear.
