Blindly remove hacks K4B
Is there a way to remove files from the OS partition of the Kindle Black without using the screen? I jailbroke it, applied the screensaver hack manually via ssh, then uninstalled the jailbreak.
Today the screen broke, and only about an inch is visible at the top. It makes reinstalling the jailbreak and undoing the hacks pretty difficult. I'm worried if I can't undo it, it will void the warranty. Is there any way to remove the hack through the USB connection or wifi?
