I've been stuck with this question for a while and never found a solution. My USB has a password protection feature on it and I think it stops it from being bootable.
Does anyone know a way to remove this feature and make it bootable? Perhaps reflashing the usb stick?
Thank you in advance.
It seems to follow this standard: IEEE1667
I found this chinese(?) page with some low level tools which I can try: http://dl.mydigit.net/special/up/phison.html
