its not a new method.. have figured it out at the day naehrwert has posted his little goodie ;-) see
here
but as mentioned by many users here and in other forums... using FSM in the process is high risk for bricking...
i bricked mine (its a NAND one), and i got a JIG (AT90USBKey with PSGradehex programmed) but no way to awake it... have to use hardware-flasher..
