I am working on this device for a friend. It was booting into TWRP but every single option failed. My computer was seeing a mass storage device but would only tell me to "insert disk" when I clicked on it (not recognizing it). I finally installed Kindle Fire Utility Drivers and then ran the Unbrick Utility, which only allowed me to clean cache. After that, my computer finally saw the device and asked me to format it. I did. I had read up on factory reset, so I placed the update.zip onto the device. TWRP allowed me to flash it. NOW, after all of that, it is stuck at the logo, being unrooted, and without having recovery mode. What do I do now? P.S. My friend would prefer that it is NOT rooted.
