    the only way to downgrade is with a hardware modification, e3 flasher, progskeet or teensy ++. not all consoles are supported if its a slim it has to be a CECH-2503b or below console. and will support downgrading. if you have a fat console it could have a nand chip and you would need a progskeet for this. you can also use minverchk.pup to check the minimum firmware that your console sill support
