Yes! From DFU mode it's a two stage process: 1) DFU update Instructions can be found here: https://github.com/mossmann/hackrf/wiki/Updating-Firmware#only-if-necessary-recovering-the-spi-flash-firmware You need to copy the .dfu file from the release to the HackRF using dfu-util At this point you will hopefully have a working firmware running on the HackRF. You can check this by running hackrf_info, gqrx, osmocom_fft, etc, but be careful, the firmware is only in RAM and a reset will cause it to be lost. 2) SPI flash update This is the non-volatile version of the firmware, instructions are here: https://github.com/mossmann/hackrf/wiki/Updating-Firmware#only-if-necessary-recovering-the-spi-flash-firmware After that you'll need to reset the HackRF, then you can test everything again. Let me know how it goes.
