Had a radio that no one knew the password for it. All I wanted was to wipe it and get it setup again. Their reset procedures were failing. I fell on my sword, and called support. After we tried it all, they just sent a new piece of hardware. However, I still had “working” hardware.
The reset instructions just failed to work (bug in the code?). I then pulled apart the radio, and found all kinds of stuff for me to connect up to. I’ll explain the process of reverse engineering the hardware, connecting the serial (UART), and recovering the device, as well as hardware that works super well to get into this. Cheap Logic probes, etc.
Intro to Hardware Reverse Engineering, as well as Intro to Glitching.
