I have a kindle fire with no OS, it has TWRP recovery and I was trying to wipe android 4.0 from it and re install 6.2.2 but I accidentally deleted the OS and any hope of re installing it. I cannot communicate with the device whatsoever using kindle utility or Kindle fire unbricker. I played with the drivers for awhile in device manager to no avail. it currently sits in 'Disk Drives' as Amazon Kindle USB device but I cannot put anything on it because it it's showing up as a proper driver or w/e. when I turn it on I get what I believe is the firefirefire triangle and if I choose to I can access TWRP, but when I left it fully boot I get a black lighting. Any help is extremely appreciate. I did look around for a bit before posting my question and found nothing that fit my problem but if there is such a thread I'm sorry I posted an unnecessary one.
