HackRF PortaPack H4M with Mayhem Firmware – A Powerful Handheld SDR Toolkit | Mobile Hacker

In the Q4 of 2024, a new #SDR (Software Defined Radio) was released: the HackRF PortaPack H4M, shipping with the Mayhem firmware. Whether you’re a hobbyist, hacker, ham radio enthusiast, or security researcher, this compact device brings a full-featured radio lab to your pocket.

In this blog, we’ll walk you through the essentials of the new H4M, flashing Mayhem firmware, copy necessary files and apps, including its differences from other tools like its predecessors, specifically H2, its hardware updates, and how to get the most out of it with both standalone and PC-connected use. If you’re new to SDR, just like me, and looking to dive deep, I recommend following YouTube creators like sn0ren, Talking Sasquach, Jeremiah of All Trades, who consistently provide excellent #RF content.
