kindle touch bricked, please help

hi
a friend gave me a kindle touch with a problem, it is with a big logo in the screen, a big empty battery and a usb cable with a lightning.
i tried to charge but nothing
i charged the battery outside kindle and i have it full
i tried to unbrick it with mfgtool but it can't enter in fastboot mode
i tried with live cd kubrick but when it arrivesto put the kindle in fastboot mode, i have allways "waiting for the device"
i don't know what more to do.
i have read something about a recovery cable for putting the kindle in fastboot.
i don't know if this cable is good for my kindle touch.
can anybody helps me.
thanks
