I have an 8.9 lte hdx that needs unbricking and can't find a method that works. It was suggested to me in another thread that fastboot is confirmed working under ubuntu (linux). Is it correct that using fastboot will enable overwriting the system with a system update to refresh the device? I believe this will be what I need to get back up and working. Are all kindle fastboot cables the same and I can just order one from amazon? I have not found much on fastboot for this device and it is the first time I have ever had to use it.
