In theory, it is impossible to brick the device, since you can always try the DFU recovery procedure. However, the updating might become fiddly in certain conditions.
# Normal procedure
1. Connect the device
2. Switch to HackRF mode via the on-screen option
3. Use `hackrf_update new_firmware_file.bin`
4. Reboot the device
# Troubleshooting
One of the main sources of problems is the quality of the USB cable. Try with several ones just to be sure before trying any other solution.
## DFU
This is a special mode to update the firmware in case of problems. To enable this, you should reset your device holding the RESET and DFU buttons at the same time, while doing this, release RESET, and then release DFU. Now you are able to use `dfu-util-static`.
## Video
The following video explains all possible outcomes while trying to update the firmware and possible mitigations:
