How the first gen ipod was reverse engineered to run #Rockbox:

1. Someone figured out that when loading a particular HTML page (for viewing on the device), the device would reboot. It crashed. A buffer overflow in the HTML viewer!

2. The device remembered what it did before the crash, so it would reload the HTML page again after boot. Unless you connected to it over USB and removed the HTML file it would stick in this cycle.

@bagder “Now the exploit was rewritten to read memory, and *blink* out the contents using the LCD backlight. A LEGO construction was built and a webcam would register the binary stream of a few megabytes of memory contents.”

Bloody hell… wow.
