I tried on my blackcat 1.4
Teensy 1.0 .Hex without backupmanager
I flip the switches back to the original position and press the start application button when finished flashing the dev board. I guess Teensy1.0 is the at90usb162.
This time it takes me to the XBM but not trace of the exploit to install it, I guess is not working.
On the list
