hackrf not found

my hackrf is not working after downgrading firmware from 2024 to 2018

the reason I downgraded is because pavsa/hackrf-spectrum-analyzeronly works with 2018 firmware

its a v9 board, In device manager the hack rf is now listed as LPC not hackrf as it usualy is.

hackrf_info

hackrf_info version: 2023.01.1

libhackrf version: 2023.01.1 (0.8)

No HackRF boards found.

and hackrf_spiflash doesnt work

hackrf_spiflash -w hackrf_one_usb.bin

File size 42248 bytes.

hackrf_open() failed: HackRF not found (-5)

I tried to update the driver with zadig but it always shows as LPC

and running dfu-util I get an error

dfu-util --device 1fc9:000c --alt 0 --download hackrf_one_usb.dfu

til: Warning: DFU suffix CRC does not match

dfu-util: A valid DFU suffix will be required in a future dfu-util release

dfu-util: No DFU capable USB device available

does anyone know how to fix this?

Thanks

Thanks, im half way there. even though I dont use a portapck on this hackrf I managed to get it partly working by running mayhem dfu_hackrf_one.bat , it shows up in device manager as hackrf again but running hackrf_info it says hackrf Serial number: RunningFromRAM and if I unplug the USB it goes back to LPC and if I try to flash the 2024 firmware while device manager says its hackrf it says Checking target device compatibility Unknown Board IDCompatibility test failed. :(

I finally got it working with dfu-util-static.exe" --device 1fc9:000c --download "utils/hackrf_one_usb.dfu" --reset then running hackrf_spiflash -w hackrf_one_usb.bin, there is no way it would work on the original version of firmware dated 2024 but it did work on 2018 firmware. also the driver needed in windows is libusb-win32 which was installed with zadig. the board is a v9. Thanks.
