So, all the exploits I knew of are now patched in the latest firmware. So I'm trying the FTDI method. Can I get some help here?


I got the exact FTDI board linked here. Using an S9 for testing, but not getting any data over serial. I've tried different computers (2x Windows 10, 1x Linux running inside a VM) and different USB cables, no dice so far.

Could be my FTDI board is bad, but I want to make sure I have the setup correct:

- Does the square hole on the board correspond to DTR or GND? When I connect DTR, the control board lights up even with PSU off.
- Are we supposed to use 3.3v or 5v? 3.3v does nothing for me, but the above works on 5v.

Any suggestions?
