I have kindle fired HDX 3rd gen, 2013, thanks to a wayward app has bricked the device, system see’s as unknown usb device adb drivers do not see it, attaching fastboot cable does nothing, other hdx’s work on same pc and are seen, is it possible to fix by getting donor hdx w/cracked screen or something and moving the innerds to uncracked system ? Update (01/19/2016) At about 25 second mark is when I get prompted on unrecognized usb device, however nothing further waiting the full 60 seconds though,
Yes you can use your old screen of the bricked machine as a donor . However have you tried a soft reset. Start by unplugging the tablet. Hold down the power button for a full 30 seconds without interruption ignoring the screen prompts then after the 30 sec release the button and then press it to start. Then do a factory hard reset to clear the bad app. Before doing a factory reset or hard reset make sure you have at lest 40% battery life. Go to “Settings” > “Device Options” > “Reset to Factory Defaults” > “Reset” .Once you’ve done this you will have lost all your apps and data except for what is in your amazon account in cloud storage Hope this helps
