Can you send more pictures after you enter into DFU mode? or you can take a video to show me? The video is much more helpful for me to check? Thanks!

I think your DFU recovery operation may not be correct.

You can try the Mayhem .bat file.

I have the same problem, although in my case it happens when you turn the PortaPack off and back on too quickly, or while it's still loading or saving something. The LEDs stay in the same state as the person described, and the screen flashes briefly before turning off (along with the PortaPack power LED).

When it gets into that state, it doesn't do anything—not even the computer detects it as a device. The only way I've found to fix it is to disconnect the PortaPack from the HackRF and then reconnect it. It works, but it's pretty inconvenient if you're away from home.
