KF1 Possible boot load corruption?

Well I have fooled around with this Kindle Fire for awhile and seem to be at a road block.
It is my wife's who stated she left it alone for a week or two, came back to turn it on and it locks up at the stock KF logo screen.
From what I have gathered that means the OS is toast.
Tried to get the KFU tool to work untill I found out that it needs to be forced into 'fastboot' to receive commands. So I built a debug cable and forced it. I then ran KFU to install twrp, said it installed and was rebooting. I had to force reboot the KF and then ran a KFU perm root script, rebooted.
Now I get to the white/blue kf logo and boot options for twrp, yet when it boots it hangs on the Teamwin logo screen.
Is this a boot loader malfunction that will require the shorting method to force USB rom loading? Or am I just missing something like a regular noob?
Thanks

First off, have you considered installing TWRP manually? You may want to check the md5 of the recovery.img before installing though.

FireTV Stick 1 boot loop. Can I restore 5.0.5?

While following links on rooting and installing TWRP on FTVStick 1, I think I may have installed the wrong TWRP. Now my stick is stuck in a boot loop at the white Amazon logo. ADB obviously doesn't see the device because it's not booting. And plugging it into a USB port on PC does nothing.
Is it a loss or is there a way to restore 5.0.5 and start again?

kindle fire gen 1 stuck in boot loop(?) after changing to ART from dalvik

I recently rooted and installed a custom rom on my 2011 (gen1) kindle fire.
I followed directions (https://forum.xda-developers.com/kindle-fire/development/how-to-kindle-fire-1-update-6-3-3-t2814955) to root.
Then I installed twrp latest version (older version did not accept my rom) https://twrp.me/amazon/amazonkindlefire.html
Then I installed the Infriction speed rom https://forum.xda-developers.com/showthread.php?t=2580232
I installed some apps... about 134 MB left in app install partition.
In developer settings I enabled ART, thinking, maybe this will make it faster...
Then it rebooted.
It was then stuck at a screen (not the android logo w/ words "kindle fire", but the bubbles screen of the os).
I decided, maybe I can fix with my pc.
Unplugged it - it then immediately shut off (loss of power??).
Then tried to use kindle unbrick utility, the various commands.
Now it is out of battery, but when I plug into PC or wall, it's in a boot loop, where it shows about 3 sec of the boot logo (android robot and words) and shuts off, before doing that again.
It is now undetectable by Kindle Fire Utility (just says "waiting" while the kfire reboots over and over), fastboot probably cannot detect either... (?) (worked one time but it just shut off again... and now doesn't work??), and can't boot into recovery.
Help.:crying:
So I'm assuming the partition ran out of storage?? but then what happened...
So I had a little luck trying to reset: ht tp s:// it stillworks.com/fix-kindle-fire-boot-loop-30462 .h tml
Then I got to the OS booting screen.
EDIT:
well that worked once... I tried to do adb reboot recovery after it got to OS boot screen (bubbles).
adb tells me:
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Then it just fell into boot loop again. ?
So then I plug in, try again, it's just the boot loop. I'm going to try again after 30 min, but maybe need to do something different.
Cause of boot loop found
So it turns out it was just out of battery... I let it charge, did the reset thing, then was able to reboot into recovery.

Problems Backing up the NVRAM Partition

***NVRAM backup solved with updated VCOM drivers, but Linux still won't boot***
I want to dual boot my Gemini with Android and Linux and I followed the instructions on the Planet Computer support webpage which recommends that you back up your NVRAM before trying to install the Linux partition.
I'm not happy to try to install another partition without backing up my NVRAM, so I spent most of Saturday and Sunday trying to get this to work without success. On every occasion, the Smart Phone Flash Tool stops responding, the Gemini will only boot if I disconnect the USB cable, and eventually I get this error message on my PC:
ERROR :
STATUS_READ_DATA_EXCEPTION
(0xC0050007)
[HINT]:
Has anyone succeeded in backing up the NVRAM on their Geminis, please???

Yes I did succeeded but first I have had to load the scatter file (from Android firmware zip) a then I have to update VCOMM preloader drivers (using windows 10 device manager)

OP has had succes backing up his NVRAM partition after installing updated Windows 10 64-bit drivers, as supplied by Planet Computers.
I would therefore recommend anyone having issues backing up partitions to make sure they have installed the latest drivers.
Finally!!! The updated drivers have "allowed" me to backup the NVRAM successfully...and Android 1.1 is available to download.
The link says Android firmware v1.0, but the downloaded file is Gemini Android v1.1. However, looking at the screenshots, I can't see any difference, except in the Android boot sequence one is offered "Configure physical keyboard"?
I then followed the instructions to install Linux as a dual boot, but when I reboot (pressing Press Esc (On) and the side button at the same time until the screen turns ON to boot into Linux) displays a Linux splash screen but then the Gemini boots into Android

keep the side button held down until it boots to the screen that shows the planets keep it held down and the screen will go black then you can let go of the side button and it will boot up in Linux

Nvidia Shield TV 2015 no fastboot, no ADB, Broken System

Hi @All:
i´ve got a Nvidia Shield TV of 2015, which was with a broken Systemimage.
I took some Updates from the Nvidia Developer´s Page, but nothing helps.
It hang always by the Nvidia Bootlogo, and after any time it takes a reboot.
The Recovery Kernel was also damaged. It was shown by the Dead Androidman.
Yesterday i flashed it, so i think, with a wrong image.
Now it won´t boot. There is no Picture or anything.
Also no Fastboot or ADB.
NOTHING!!!!
Have anyone an Idea, what i can do?
Is it possible to get an Image directly to the eMMC?
Greatings
Sebastian
Use a keyboard or game controller to boot fast boot
Try to recover through recovery image on shield forums
