You may use the following:
`dfu-util --device 1fc9:000c --download hackrf_one_usb.dfu --reset`
And after that, without disconnecting it, you can upload the firmware:
`hackrf_spiflash -w new_firmware_file.bin`
If you are in Windows, from the release package double click `dfu_hackrf_one.bat` and follow the instructions. Do not disconnect or reset your Portapack after that procedure, continue in the step 3 of the [normal procedure](Update-firmware#normal-procedure).

3. Connect your device to your computer and follow the DFU instructions above
