EDIT: Got it fixed, another computer worked with ADB.

So I know there's a lot of posts here with a similar situation and I tried to find a solution but I'm at my wit's end.
I recently tried updating my KF using the Cyanogenmod built in nightly update system. When it rebooted after downloading I got stuck in this boot loop for TWRP. It shows the "teamwin" logo, then the screen flashes and it's back to the logo again.
I can connect via adb but unfortunately my device is unauthorized. Obviously, since I'm stuck at this logo I can't authorize it manually on the KF.
I definitely have the latest version of adb as I just downloaded/installed it from the SDK manager seconds ago. I installed all the drivers and added the blurps of code to the Google USB driver and the adb_usb.ini. I tried deleting the adbkey files and restarting adb. I tried different USB cables and different USB ports on my computer. All this to no avail.
Anyone have any ideas besides buying a fastboot cable? That's the only thing left that I can think of to do.

Guess I'll try getting that fastboot cable...
I had the same problem. The only solution that worked for me was buying a fastboot cable and then re-flashing the TWRP recovery img.

Yep, I just received mine and did the same.
Thank you for all the help in advance!
Current state of device:
Fire HD 7" factory cable plugged in stuck on fastboot screen not loop just stuck no access to ADB (device not found[debian gnome])
I was deleting my previous ROM to go back to stock. I wiped my cache, os and everything then went to go and install the stock ROM and my little one managed to power the kindle down. I turned it back on to find kindlefire logo on the screen but it doesn't go past that. I built a factory cable and now it displays the fastboot logo but nothing else, not looping just frozen on the fastboot screen. So the computer [debian gnome] can't find the device when using ADB. (ADB is working with my other devices) I tried to follow a post about using the fastboot cmd to install the system.img, recovery.img and boot.img but did not know exactly what I was doing at that point. Is it done for? or is there hope?
Any help would be greatly appreciated!
There is hope. You could try following the commands in the batch file from this post.

I've never tried it from Linux but so long as fastboot is working you should be able to flash the 3 images and then wipe data.
Thank you sooo much! this worked like a charm. I downloaded the img files and loaded them to the kindle via fastboot then rebooted and wala back to a fully functioning kindle. Thanks for the link!!!!
Glad to hear it helped you out.
Help me please
I have bricked my device. I can no longer get it past the bootloader Amazon image and can only get it into fastboot. Had root on device and was attempting to flash twrp so that i could install some custom roms. When flashing twrp the device restarted and has been stuck in a silver amazon bootloop. With the help of root junky's supertool i can get into factory recovery. but cannot sidload origional system back. I was gonna go back origional and re root. But can not get it out of bootloop. Tried using the system recovery thread found in second post on this thread and recieved an unsuccessful. Am i done for.... Kindle just stuck on fastboot screen now
Does your device have the front facing camera and the mini hdmi port?
When I flashed the 2nd Boot loader and TWRP, I rebooted and got stuck in a bootloop. I heard there was a way to fix this by resetting the IDME bootmode. I was wondering how to do this.
friend edited my build.prop and now my Fire is stuck loading the fire logo. Fastboot also gets stuck and my PC is not detecting the Fire :crying:
nvm got into recovery
I updated my oneplus and i got the TWRP decryption message, so i formatted it back to the stock format.
now all the phone does is boot into the bootloader but gets stuck on the boot screen of Blu Spark 3.1.1
my computer wont recognize it while its in the bootloader or while its stuck trying to boot in twrp
is there anything i can do or is my phone screwed at this point? i see a lot of threads that would answer parts of my issue but nothing that covers this as a whole. id rather ask for help now while there may be some hope.

So no response to fastboot commands, while in bootloader-fastboot mode?
Are you sure you installed the right drivers for your pc? If all else fails, you can do this.
This is how I fixed my phone when i was stuck at a black screen. You can also try a different usb cord or port. Check device manager and see if it recognizes it when its plugged in. hope this helps!

can you boot into fastboot? if your phone can boot to fastboot mode..just flash stock recovery image..then flash rom via adb shell (better flash the stock rom). if it works you can reinstall the custom recovery image or something. dont forget to erase everything via stock recovery..
