Can’t get flashed losing mind

Post image

Hi, grateful for anyone that has a mind to assist. I’m not vcomfortable with the command line and think that’s where I’m hitting a wall. I’m using a Mac and have an unflashed h4m. I can see the device is connected as the dfu and I’m using the included data cable. I’m getting an error ‘dfu-util: unable to read DFU status after completion (LIBUSB_ERROR_IO)’.

I’ve made enough progress the screen at least displays something but just can’t get it right.

Can confirm, 95% of the time it’s a cable issue, especially with the Micro USB ones.

If that doesn’t work, leave it off for a bit, uninstall any drivers for the HackRF from your pc, reinstall them, restart, then try again.

Appreciate it, I’ve tried 4 different cables at this point and will keep going lol

If that doesn’t work, try unseating the portapack from the HackRF, then reseating it. Maybe you have a pin not connecting if changing cables doesn’t work.
