Accessing Hidden Serial Consoles – USB-to-TTL Demo 1/2 – Hardware Hacking Series #4

Accessing Hidden Serial Consoles – USB-to-TTL Demo 1/2 – Hardware Hacking Series #4 In this video I demonstrate how to connect the USB-to-TTL device and access the serial console with PuTTy! I also show what a bad connection looks like, i.e. when you’ve mixed up the TX and RX cables, the boot loader menu, and last but not least, interesting boot messages that may enable us to gain root at a later point in time. *** Want early access to my videos?

If you break your router while modifying it like I do in my videos, then it is your own fault. Soldering on equipment is not without risks. (I haven’t managed to break my routers yet though.)
