RIP to all those thinking this will work on unmodded switches, if u think otherwise you really underestimate the switch security when it is in its unmodded state..
so this cart if it is a flashcart will not work on unmodded switches, thats for sure.
do not use toolbox... as it somehow corrupts during installation of fw.. best is usb firmware install. takes 5 mins to open up the switch and make usb connector to modchip direction is correct and UP direction before flashing.
