I run the Mayhem firmware on m HackRf and I've always forgotten to post anything about it. Basically the portapack with Mayhem firmware takes the HackRF from a home/bench use only to a fully portable and useful field tool with full transceiver capability.
The beginning of this video shows just how easy it is to flash the firmware- blink and you miss it - it is THAT easy
People are still actively developing the firmware in GIT here: https://github.com/eried/portapack-mayhem
