Hello fellows!
I'm afraid, I bricked my kindle.
I wanted to check out the permissions for /app using ES-File Explorer. My screen went instantly black and stuck. I didn't change anything, I just clicked on "details". I killed the device (holding down power button) and afterwards it doesn't boot. The kindle logo stays gray and it reboots 1 time. This reboot ends in the Fire System Recovery, where I can reboot the device or do a factory reset.
Factory reset didn't help.
I have one problem fixing the device:
- The device is only recognized as MTP-Device while it tries to boot the first time. And this is not very long. It isn't named Kindle, but Android in "Devices and Printers". Unfortunately I can't uninstall or "update" the driver, while the kindle tries to boot.
---> ADB tells me: "error: device '(null)' not found" .
Do you have any idea how to save my kindle?
What I wanted to do before killing the device:
- Get the kindle to show Wallpapers (Totally worth to brick the device! -.-)
EDIT: I tried a second Factory Reset. Now it is fully stuck at the grey boot logo. But my system detects the kindle now correctly.
Next problem: adb shell command end in: "- exec '/system/bin/sh' failed: Permission denied (13) -"
EDIT EDIT: Getting the kindle into real bootloop is not always possible. It happened once and now I'm stuck in the System Recovery again and can't connect to the device :/
You might have to reroot the tablet. I think you can do it with ADB, or HDX toolkit might work. Or maybe you don't have to root at all, I recommend to reinstall ADB.

You didn't indicate if your device was rooted (assume yes), Safestrap installed, FireOS version, etc. But in the end it really doesn't matter. With a locked bootloader there is nothing you can do to recover from this type of failure. Even if the device is detected you will not have adb access. Nor will fastboot commands work (most are disabled). Native factory reset only clears the data partition; it does NOT fix errors in the system partition. If still under warranty contact Amazon about a replacement.

It was/is rooted.
So even a Fastboot cable won't work?

Fastboot cables are useless on a HDX as 1) device interface does not support alternative pinout; and 2) fastboot environment is crippled.

Oh man! **** Amazons Bootloader!
I called them and they told me, that there are no Tablets to replace mine. They'd give me a kindle 8.9 for 303€ and that's all.
Thank you for answering. I'm going to throw my kindle away

Well, I wouldn't toss it just yet. Stick it on a shelf and move on. Possible (albeit unlikely) a future unbrick method or bootloader exploit will become available.

I hope so. Someone said they found how to get direct eMMC access.
After upgrading to CM 12.1 everything was just fine. Got my tablet to charger and left it there for a while. And then i saw that i was looping.
It's trying to enter recovery (TWRM) "or something like" and restarting.
I' sitting on forum for 3 days already. trying to get some information and did lot's of things. Nothing helps.
Can anyone help me with this somehow? I'm almost crying and losing it (not really, but that what i feel inside)
Please. Any help. I think I've read all forum about this thing.
Thank you.
Do you have the real TWRP (i.e. not Safestrap!) & an unlocked bootloader?
don't think so. or better say i'm not sure about it. how can i check?
Edit:
i can run adb and after command "adb devices" it shows serial number and status: recovery.
i can use the command adb reboot-bootloader which puts me in fastboot mode. but then i try adb devices and have nothing there.
also, any command like "fastboot...." gets me to "waiting for device" and nothing more.
I tried two different computers. all ports. all cables that i've found.
Edit 2:
also after command "adb shell" i ca see "~ # ←[6n" and i can put there only reboot command
Well, first of all CM12.1 requires TWRP & an unlocked bootloader, if you don't have those, flashing CM12.1 was a bad idea.
So what happens during boot? Do you see the Safestrap logo and had to either wait 10 seconds or press continue to boot? Can you enter Safestrap there by pressing Recovery? Which Safestrap version is it (if any)?
The real TWRP can be accessed by pressing and holding Volume up, then pressing and holding Power, release both when the grey Kindle Fire logo appears on screen.
As having TWRP is a key requirement here, it's important to figure out what you really have (either Safestrap or TWRP).
And do NOT do a factory reset in amazon's stock recovery with Safestrap installed! Will brick the HDX!
As @Davey126 mentioned here you can check whether the bootloader ist unlocked by opening a fastboot prompt (i.e. DOS box, then change dir to your adb directory), then enter:
fastboot -i 0x1949 oem idme
You will only get a response if unlocked.
If you use Windows and get the waiting for device fastboot issue, try these drivers, could be a pain in the ass to install them in Win8(.1)/Win10 x64 though. And note that you probably need to (re-)install the original Amazon Drivers again to get the HDX noticed in Explorer in order to get files copied it.

Also verify you have a Kindle HDX ... not HD or generic Fire.
the fastboot command got me still only 1 message "waiting for device"
Tried to install drivers. While looping, in device manager, i can see "Fire devices: Android composite ADB Interface"
and "Portable devices: MTP USB Device"
If i enter fastboot mode, gets me to "Other devices: Unknown device" and i just cant figure out how to install the drivers. Tried to download some stuff. plugged, unplugged.
Edit:
After some work done with drivers, i input adb kill-server and adb devices and get "Serial Number Unauthorized"
So maybe i should change word "work" to "messing" with driver
what do i do from here... is there any live chat for it maybe? or i can call someone?
Well, do you have the real TWRP or Safestrap? Can you enter recovery?
well, only thing i get it's blue screen and "Teamwin" and after like 3-4 second restarts and go on looping same "Teamwin"

Still haven't answered Safestrap or native TWRP query (you should know). Do this:
- long press power until device shuts off
- restart device with power button (only)
- detail the 1st, 2nd and 3rd screens you see
If you do not have native TWRP (with unlocked bootloader) you likely borked your device with the installation of CM 12.1. Generally not repairable.

Ok, that should be the real TWRP, the Safestrap screen looks different.
This could mean you've TWRP installed, but the bootloader is locked. So I'd suggest to unlock the bootloader, you can't screw up anything, and can try this nice tool.

To check if your bootloader is unlocked (assumes you previously unlocked and still have the prerequisite software installed on host):
- power down device
- press vol-down + power; release both keys when "[fastboot]" prompt appears
- tether your device
- open a command prompt (assuming Windows)
- issue command: fastboot -i 0x1949 oem idme ?
- you will only get a response if bootloader is unlocked
If the (Windows) host displays "<waiting for device>":
- press <ctrl>-c to break wait
- start device manager (different window)
- located device with explanation mark (likely under "portable devices")
- right click -> update driver software -> browse my computer... -> Let me pick...
- select driver from list (ideally one that contains the words 'fastboot'); might have to try a few
- reissue above command
Bit of a PiTA ... might be easier to simply try the one click unlock tool as there is no additional risk to your device. It will either work or not.
I guess i'll check it only next week. Leaving all this things for the weekend.
I'll keep you updated guys.
Anyway, i really appreciate your help! Thank you so much for helping
same problem
Good evening, I am very interested by the article, in fact, I currently have the same problem and I began to be very sad. all stages cited by oreal Crast are similar to the ones I tested. when I enter the command prompt 'adb devices' I get the number of my tablet and status RECOVERY.
'adb shell' gives me "~ # ← [6n"
I even re installs the uboot, boot.img and TWRP freedom by following the steps in one tech site
but at reboot, by entering the command "fastboot oem recovery 0x1949 -i 'my tablet again has a boot loop on teamwin.
i want to resolve very fast this problem because i need my tablet urgently:crying:
ps: I don't think that I can meet these problems because after having bought my tablet to a friend (the tablet possessed CyanogenMod 11 android 5.0.1 I think) I did a factory reset . it is from this manipulation on my tablet reboot teamwin.
thank you for your helping

I assume you have an unlocked bootloader and were running 'native' twrp (not Safestrap) when the problem occured. Unfortunately, there is no known 'quick fix' recovery from this failure scenario (boot looping on teamwin spash screen) as you have tried to reinstall twrp without success. Someone very talented with android might be able to unravel the problem. Best guess (and it is only a guess) is the recovery partition became damaged to such an extent it the contents can not be replaced without performing a low level format/reset of your device.
Some curiosities:
- Android 5.0.1 and CM11? (impossible combination)
- TWRP freedom? (not supported on HDX)
Are your certain your device is a HDX and not some other model?
same problem
for android version I listed above, I do not know exactly because I have used my tablet a day without really paying attention to it but I think I saw the android 5.0.1 but regarding cyanogen, I just imagined it based on readings on the web.
for this is my tablet AMAZON KINDLE FIRE with a HD 8.9 and the TWRP I recently flashed, I got through the website wikicyanogenmod in the "on how to install cyanogen hd amazon kindle 8.9.
I can not post a link because I am new to the forum so I can only quote the sites where I could download my data.
* I really count on your help to all.

You still haven't made it clear whether you have an HD or HDX model.
You're on the HDX forum, but you're talking about documentation on the CyanogenMod wiki for the HD 8.9.
The problem likely stems from the fact that you flashed a recovery for the wrong device.

I searched the web and I have definitely amazon kindle fire HD 8.9 because even his appearance differs from the HDX 8.9.
no I do not really think the problem comes from the data flash HD 8.9 (wikicyanogenmod) because I flashed the data after doing a factory reset without actually knowing that this would pose a problem with amazon tablets.
the tablet was working well but I was unable to connect to the wifi. I thought it would be nice to change rom and install a suitable and stable rom for my tablet, but my operation I was surprised because I had never heard of this kind of problems caused by an factory reset
Hi all!!
This is for all the people who managed to softbrick (or hardbrick) their Lenovo Tab 3 8' (TB3-850F) tablets!
All you will need link, at the end of the post. I don't know for how long it will be up, but you can use it for now.
By the way.... Should you find something useful here... please hit the thanks button in the end
A. Unbrick
This requires flashing a clean stock rom. You will need:
a. stock rom for the TB3-850F (Google is you friend )
b. Sp Flashtool (you can download from their official site). From there, also download the MediaTek USB VCOM drivers and Driver Auto Installer v1.1236.00 (or any latest version).
Steps:
1. Install the windows drivers you downloaded
Note : If you encounter problems installing Windows drivers in Windows 10, google how to install unsigned drivers in Win10
2. Open the folder you extracted SP Flashtool and run it as administrator.
3. Unzip the rom file you downloaded.
4. Inside the folder of your unzipped rom file, look for a file similar to XXXXXXXXXX_scatter_file.txt
5. Load this in the SP Flashtool (click downlad tab, then scatter loading, load this file in there. It should load your rom you will see some colours, etc...
The tricky part:
Assuming you have correctly installed the drivers:
1. turn off the device (well if bricked it is turned off all ready) just make sure, and in SP Flashtool click options and 'with battery'.
2. Click the green download button on SP Flashtool.
3. Hold down the Vol down key on your device and connect it to a usb port.
4. If you see a red line and continue to yellow, all is probably good! Don't let go of the vol - button until yellow line reaches 100%
B. Root and TWRP recovery
This requires that you have or download:
a. platform tools (adb and fastboot)
b. a twrp.img (image file) for the lenovo TB3-850F copied to external SD Card and platform tools folder (google is... useful )
c. latest supersu.zip (flashable) copied to an external SD CARD
d. busybox.apk
Steps:
1. Grab tablet, go to settings ---> about tablet ---> click version number 7 times to enable developer options
2. From settings again click developer options and enable OEM Unlocking and usb debugging
3. Navigate in the platform tools folder. While holding SHIFT right click and select open commandline here (or similar)
4. Connect tablet to PC and in the command line issue: adb devices
If a weird number shows up and says device on the left you are all good to continue.
5. Now on the command prompt again issue: adb reboot bootloader
Your tablet should now reboot to fastboot (big Android, laying down)
6. Issue command: fastboot oem unlock (also check tablet screen for confirmation)
Wait a little bit and reboot your tablet. (should work with holding the power key down for a little longer than 10 seconds. If not hold down volume key and power button for the same amount of time - tested and working)
**At this point it is ESSENTIAL to leave the tablet to fully boot. The bootloader unlock triggers a FACTORY RESET which you must leave to complete and set up your tablet from the beginning.
** It is also ESSENTIAL to complete the boot and set up cycle because, after the automatic factory reset you will need to RE-ENABLE developer options and usb debugging. Once you are done continue to 7.
7. In the platform tools folder copy the twrp.img (you should have downloaded earlier, check upwards... )
8. Open the command line again and type:
a. adb reboot bootloader
b. fastboot boot twrp.img
** This will load up TWRP recovery only for this boot time.
****BE EXTRA CAUTIUS TO -NOT- ALLOW twrp to make modifications. Essential! Should you do otherwise go back to how to unbrick your tablet.
9. Choose install, and install supersu.zip.
10. Choose reboot to system and allow complete boot cycle! Essential!
11. Your tablet should now be rooted. However to succesfully flash the twrp recovery you need to have Busybox installed. Download as .apk and install it (at the time of writing this I believe Busybox 54 is the latest version).
12. Once installed back to the windows terminal and issue:
a. adb reboot bootloader
b. fastboot boot twrp.img
ONCE AGAIN - DO -NOT- ALLOW twrp to make modifications!!!!!
13. From you external SD Card install twrp.img, select recovery when prompted.
14. Reboot to system and enjoy!!!!
Note : Install an app that makes it easy to boot to recovery. (I personally use root essentials - Trying the combination keys did nothing for me, or just poped up the chinese options menu. That does not mean the recovery has not been installed correctly. Booting to recovery from rootessential menu, boots straight to twrp)
All you will need and credits:

Results:
(it is in Greek, but you get the idea )
Hope I have helped! Happy playing with the commands and whole process! :good:
Lastly, if you get stuck at any point, you can either use this thread or PM me for further advice, explanation and/or any kind of assistance.
Note: Special thanks to @MotoJunkie01 for actually taking the time to further help people on this thread, as unfortunately I do not currently have the time to do so myself. It is worth checking out @MotoJunkie01 's threads also. There, you can find very useful and updated information.

Thank you for the encouragement. I am in hopes that we can eventually get a dedicated device forum for the tb3-850f. I truly believe this tablet has the potential for plenty of future development.
@r&xp I love you so much, I was in the same predicament as you and you helped get my tablet running again. Just wanted to mention, I had to hold volume down when plugging in the USB for the SPFT step instead of volume up. THANK YOU AGAAAAAAAAAAIN <3

Glad it worked for you. Isn' t it like a really good feeling when you actually see your bricked device boot correctly for the first time after you had almost deemed it unusable???
(also... a... small request... could you please click on that thingy... you know... that ehhh... thanks button??? :angel::angel:)
Just an update, since damaging my TB3-850F, I have since ordered another unit from Office Depot which is due to be delivered Monday or Tuesday. Once it arrives, I'll finish my TWRP flashable stock 6.0 ROM for this device and start back on the modified stock ROM.

Looking forward to it. I picked mine up from walmart just yesterday for using as a google maps/car media center
My Lenovo Tab 3 replacement finally arrived in the mail. I'll be picking up where I left off on compiling both unmodified stock and custom stock-based ROMs for this tablet.
On my modified stock based ROM, I'm considering the implementation of Substratum (Root Ver) for theming, but I would like to get the input of other device owners first. So far, I have debloated, deodexed and zipaligned the OS. I am including the modified/patched boot image with SuperSU v2.79 SR3 binaries installed for systemless root, Nova Launcher, Pixel Icon Pack, BusyBox v1.26.2 binaries pre-injected in /su/xbin/, and Kernel Adiutor-Mod installed in /system/apps/ for user defined adjustments to the stock kernel and governors.
You guys please give me input on what you would like included in the ROM. Thanks

I had a Lenovo Tab3 that bricked during the initial set up and this saved me for having an expensive paperweight! The process worked like a charm. You ROCK!

Try again to get TWRP installed to your /recovery partition or, alternatively, try to simply boot into TWRP from fastboot with the fastboot boot twrp.img command. It is common for members to experience some difficulty in installing custom recovery on this device. It has been my experience that most members are successful the second time around.
Thanks MotorJunkie!! But mine after was saved from brick from this thread, i was rooted it also by your instructions from other thread.. Now the gps from GoogleMap doesn't determine the location (even the location already turned on ) ... Plus i couldn't check the systemupdate ( it says connection network failed even i was connecting to wifi already) ...
What should i do, or do you know how to fix it?

System updates (OTAs) won't install on rooted operating systems. To install an OTA, you must have unmodified stock /boot, /system, and /recovery partitions installed. On the GPS issue, go to Settings, Apps, and ensure Google Maps has been granted location access permission.
Hi ...
I followed this guide but during the unbricking' I unplugged the device from USB (since I could not see any input on device or indication in SP Flash Tool).
Now the device will not turn on at all (previously I would see the Lenovo Logo splash screen but then it would just stay at this screen. Now i do not see anything).
When I plug into computer by USB, it causes my computer to freeze up (Windows 10).
Any ideas or is this now completely bricked? (hard bricked).

It sounds like a hard brick. I can't speak for the OP, @r&xp on this, so you may want to get his advice. Have you tried the OP's methods of using your hardware buttons for forcing the device into adb/fastboot recognition? I think this is your only chance of recovering it. By it not powering on, from my experience, a bootloader or bootloader dependent partition has been corrupted, thus hard bricking the tablet.

Hello, I'll weigh in on this one. There are multiple threads above the TB3-850F on this forum and also another forum.
I initially followed a different thread and instructions which caused my problem. Notably do not allow TWRP write access !!! This mistake caused the soft-brick.
Anyone following any other advice about TB3-850F or downloading any other image BEWARe. Only follow the advice in this thread by r&xp:
https://forum.xda-developers.com/android/help/lenovo-tab-3-8-tb3-850f-unbrick-root-t3598727
Following this advice I now restored original image and then rooted in just a few hours.. Thank you r&xp for the good advice. :laugh:
My HDX 7 64GB is stuck in a boot loop after 4.5.5.3 update (I did not believe amazon would offer another update so i did not block OTA updates). It was fully Stock except for King root.
Now after the first boot loop it boots always the Fire System Recovery.
Is there any possibility to fix this?

Not likely short of placing the device in 'bulk' mode and taking a series of rather technical steps to erase and then rebuild your device. Entering bulk mode may be tricky if it is unstable during boot.
How would I place my HDX 7 into 'bulk' mode?

Ok. I tried to get my HDX 7 into bulk mode, by using a fastboot cable. But it only enters 9008 QDL mode, how do I get from there to the buk mode?
As I tired different things. My HDX 7 is now stuck with the grey kindle fire screen, but I can see the device in adb. The problem is that I can not execute any command, because it is shown as unauthorized. Is there a way to still boot fastboot?

A fastboot (aka 'factory') cable is ineffective on this device. Being stuck at the bootloader logo with no connectivity is generally fatal. Details matter; how did the device and up in this state?
@draxie - thoughts?
I wanted to unlock the bootloader and rooted it via Kingroot, but had no time that day to get further. Some days later I discovered the HDX 7 was booted to the stock recovery.
I tried to reboot it, but it always tries to boot the rom and start over and boots the stock recovery.
Then I called amazon, and they told me that my HDX tried to update to 4.5.5.3 and that they can not help me.
Then I tried the factory reset, but it did not help either.
Through experimentation I noticed that if the tablet booted while connected to my linux notebook, it would sometimes stop at the grey kindle fire logo and offer a adb connection, that I sadly could not use because i don't have the necessary ADB_VENDOR_KEYS.

I am not aware of any method to reliably force a device into 'bulk' mode via button pushes, etc. The member referenced in a previous post has the most experience in this area; see if he responds.
FWIW - accepting a FireOS 4.x OTA update on a rooted HDX device is almost always fatal.
Hopeless...

Condolences, perhaps...
If the bootloader is unlocked, Power+VolDn won't enter fastboot
(although that doesn't hurt trying), and I don't know of any exploits
that would get adb executing commands on an unauthorized device.
(Of course, trying "adb reboot bootloader" won't do any harm, either.)
If adb used to work before, there _could_ be an absolutely minuscule
chance that whatever host was used still has adb keys in the .android
folder of the relevant user account's home directory, but given that factory
reset was performed, the corresponding public key(s) on the device are
probably gone... Still, if there are keys in .android (and, especially, if there
are different versions on different hosts and/or under different user accounts),
then testing them all may be worth a try. Just in case...
The steps involved are
Stop the current instance
Code:
adb kill-server
Copy the keys to try to .android
(on the test host in the test user's home directory)
See if "adb" manages to connect:
Code:
adb shell
(This needs to be run as the "test" user.)
And, the above steps should be repeated for each set of keys....
I would NOT hold my breath, but one might get lucky.
I’ve been lurking on these forums for a while and I have decided that I’m willing to take the risk to unlock my Thor’s potential. I have made sure to read through advised reading materials, and searching through other posts before posting. (I tried figuring out how to quote multiple posts to make this thread easier to navigate but I couldn't, sorry)
Device: Kindle Fire HDX 7” 3rd Generation running Fire OS 4.5.5.3
I will be using a Windows 10 Home machine to do this.
Purpose: Allow for the device to work well in Google’s ecosystem so I can have a useful device for medical school.
I am currently trying to learn the steps outlined here, but I have some concerns:
Does it matter whether or not I factory reset my device before I begin?
Will my computer’s OS cause any issues? According to this, there might be some driver issues? Should I download the “Motorola Device manager”?
Where is the “aboot_vuln.mbn” file? Do I obtain it once I follow the steps in order?
I want to use “Minimal ADB and Fastboot” instead of the attached “15 seconds ADB Installer v1.4.3” because the later has not been updated in a while and the former was updated this month. According to the install instructions for the former, I need to have my device already plugged in and the “kindle fire USB driver” already installed. Will this affect step 4 of the procedure or anything else?
On step 5, am I correct in my assumption that changing the driver will be a simple few click process?
On step 6, do I follow the directions as they are quoted, or the ones on the original forum? If the later, does “change to the directory with the extracted dd.exe” mean to type the directory or something else? Also, a poster here stated that he got error message on the second 2 commands instead of the first, is the concerning at all? Should I take any precautionary measures?
Once step 9 is completed, can the kindle run as normal if I don’t flash anything? And what does it mean “get into the TWRP”? I’ll simply be in the recovery menu on the kindle? How do I flash my chosen ROM using TWRP?
What ROM do you recommend for my needs? And could you provide me a link to the correct download/discussion board? I would prefer a ROM running at least Nougat that has long-term support planned. I read that “Fire Nexus ROM” is pretty basic, so I don’t think I want it. As of now, I’m looking at CM/Lineage 14.1, but I don’t know what ROM would work on my device from the website. AospExtended seems like a good option but apparently, there are wi-fi issues which are a deal-breaker.
Thank you so much for reading through this. Hopefully all my research and proves to be useful for anyone trying to help. If I’m able to get this working cleanly, I would be willing to make a cleaned up guide for this version and device to better aid future people.

Hello @hwwof -
You have done your homework (thank you!) and presented reasonable questions. I'm going to answer the first five 'in-line' below. Responses will be brief to keep the thread serviceable for those accessing XDA content on small screens; don't read anything into that. Bounce back on any items that need further elaboration.

No; however, it would be better if you did NOT reset the device.

Nope. Drivers installed via the Motorola Device manager are properly signed which mitigates any potential issues on 64-bit Win 10 builds (yet another reason to use the Moto drivers vs others that have been posted)

It's contained within aboot-13-thor.zip; just named differently.

Good idea. Your device does not need to be tethered while installing Minimal ADB and Fastboot. Take note of where the package is installed (typically "C:\Program Files (x86)\Minimal ADB and Fastboot") and practice opening a command window focused in that folder. To make life simpler you can direct the installer to place the files in "c:\work" which is a lot easier to type.

Yes - but here's were it gets interesting and a bit frustrating. Even with the Moto drivers Windows can be very fussy communicating with HDX devices. To complicate matters there are two modes to deal with: ADB and Fastboot. You'll learn which is which as time goes on and will likely have to switch Windows drivers for each mode. Sometimes a reboot is needed to get everyone talking. Note there is no danger involved simply tethering your device and issuing basic queries.
To test basic ADB communications:
- execute step #2 (only) from the linked procedure
- open a Windows command prompt as outlined above
- boot HDX into FireOS and move past the screen lock
- tether device to windows; take note of any noises and/or confirmation messages
- in the window command prompt issue the command "adb devices" and press Enter. What happens?
Post back results and we'll go from there.
Thank you @Davey126 . I appreciate you taking the time to help me out. Answers to the other questions would be very appreciated as well!
Here are my results that you requested:
The kindle beeped, and the internal storage popped up on my computer. I ran the minimal adb and fastboot program, and got this output:
Code:
C:\adb>adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
D0FBA0A0351401GB unauthorized
C:\adb>
And on the kindle, I got a “Allow USV debugging” popup on the kindle and it showed my computer’s RSA Fingerprint. I then pressed allow. I took note of the fingerprint just in case. I then tried ejecting my device but it wouldn’t let me because a program was still using it. I ran “adb devices” again and got this output:
Code:
C:\adb>adb devices
List of devices attached
D0FBA0A0351401GB device
C:\adb>

Second response is positive. Next issue the following command: 'adb reboot bootloader'. This will place your device in fastboot mode. If you are very lucky a 'Ready' prompt will appear on the device below the word 'fastboot'. Most likely you will need to head to Windows Device Manager, identify which entry is associated with the tethered HDX and then change the device driver to 'Moto Composite' or something similar (might not have the wording exactly right). Once you get a 'Ready' prompt issue the following command: 'fastboot devices'. If you get a response similar to 'adb devices' then you are good to go.
Hints/tips:
- to help determine which entry(s) are associated with your HDX tether/untether your device while Windows Device Manager is open
- right click an entry to change the device driver; navigate 'Browse my computer ...' -> 'Let me pick ...'; do not choose any of the automated options
- if you can't get a Ready prompt and/or an response to 'fastboot devices' reboot both devices and try again
- if still no joy change USB ports and cables; the latter are especially problematic (people never believe that until trying 1821 other things - ugh!)
Report back and we'll go from there. I know you prefer the rest of your questions answered up front. Experience suggests an incremental approach is more productive - for you, me and future readers.

Thank you! Now it says "ready" but I'm concerned about how to unplug it without messing anything up. here's the output:

You are correct that I would prefer having all the answers upfront, but it's only so I can then question the answers to get a better understanding before messing with the device. A quick reply would be appreciated!

Great!! The purpose of this exercise was to validate connectivity in two different modes and, if needed, provide a safe 'test' environment for remediation. No worries about breaking the tether if there is no active data transfer taking place. Simply unplug and then long press <power> until the device shuts down.
In response to your other questions:
Q: On step 6, do I follow the directions as they are quoted, or the ones on the original forum? If the later, does “change to the directory with the extracted dd.exe” mean to type the directory or something else? Also, a poster here stated that he got error message on the second 2 commands instead of the first, is the concerning at all? Should I take any precautionary measures?

Q: Once step 9 is completed, can the kindle run as normal if I don’t flash anything? And what does it mean “get into the TWRP”? I’ll simply be in the recovery menu on the kindle? How do I flash my chosen ROM using TWRP?
A1: You should assume all content on your device will be erased following completion of Step #9 (although it will likely remain intact)
A2: The two files you will be 'flashing' with the dd command should be located in the same folder as "Minimal ADB and Fastboot"
A3: Deal with that later (flashing ROM)
Q: ROMs:
A: All of the Nougat based custom ROMs for HDX are stable and feature complete. Nuances are subtle and probably not worth worrying about now; you can always change later. My personal preference is AEX (AospExtended). That said, Lineage 14.1 and Slim 7 are both excellent alternatives.

Quick activity while you wait:
- boot into TWRP (power down; press <power>+<vol-up> for ~3 sec then release)
- swipe to allow modifications
- tap the backup option, select all partitions except cache, swipe to execute
- when complete tether device; should connect in adb mode
- from look for a new device/drive in Windows File Explorer
- click <device ID> -> Internal Storage; should see a folder named TWRP
- drag or right-click folder to a storage location on your Win 10 machine
- congrats! You have just made a backup of your device -and- placed a reserve copy on your Windows machine
Comment: prior to backing up you had completed the most risky tasks (stuff that could have yielded a soft/hard brick). It's all downhill from here. Will post more info on unlocking and installing a new ROM in a bit; real-life is calling . Fully understand if you need to sleep; post will be waiting in the morning. Penning this from Northeast USA; timezone UTC-5.

I appreciate you so much! And I completely understand. I hope everything you're working on gets resolved!
I have backed it up as you suggested! Since the back-up is also on the internal drive, it will be deleted later, correct? It's 5gbs out of the already small storage space.

With the 5GB TWRP backup folder safely copied off-device you can delete the local copy at any time...although there is no immediate reason to do so.
Next step is to unlock the bootloader:
- verify 'get_code.bat' & 'unlock.bat' reside in the same folder as adb.exe and fastboot.exe
- look around to see if you have a file called 'unlock.code' from a previous run of 'get_code.bat'; if so place it in the same folder
- tether device and boot into fastboot (easiest way: boot into TWRP and then use reboot menu to boot the bootloader) [<--what an awkward sentence!]
- enter 'fastboot devices' to validate communication between host and device
- execute unlock.bat; if you get a green 'OK' the bootloader is unlocked!
- if not boot into FireOS (get past unlock screen), tether, verify adb communication is working and then run 'get_code.bat' to (re)create the 'unlock.code' file
- repeat steps 2-4 (above)
If that doesn't work and/or you are unable to boot into TWRP then a bit of extra work will be needed to generate a valid unlock code. Brief outline:
- download legacy Fire Nexus ROM from here (it does NOT require an unlocked bootloader)
- tether device and into TWRP
- from Windows copy downloaded ROM to a folder on the device (suggest creating a new folder with your initials as the name)
- from the TWRP main menu tap Wipe then swipe to perform a 'factory reset'
- from the TWRP main menu tap Install
- navigate to the folder where you stored the downloaded ROM
- select the ROM zip and then click to install
- when complete allow the device to restart; after a 3-5 min it should boot into Fire Nexus; skip the Google config (not needed)
- enable developer options and adb bridge
- tether device and verify adb connectivity
- run 'get_code.bat' to generate a fresh unlock.code file
I will be traveling much of Sunday with irregular network access. I'll try to respond to an questions/problems as time permits. Apologies in advance for any delays.

Welp, device won't boot into FireOS. It boots straight to Fastboot. I tried Installing nexus ROM but I got "can't install this package over newer build updater process ended with error:7".

Error 7 is pretty generic and can be due to a conflict between install package and TWRP or an issue with the system partition. It's a solvable issue without too much work. They the following in the order listed.
1) In TWRP tap wipe -> advanced. Tick system, data, dalvik and cache; leave internal storage unticked. Tap the appropriate button to execute. Return to main menu and reboot back into recovery. Then try to install the Nexus ROM.
2) Download an older build of TWRP from here and transfer to adb/fastboot folder on Windows. Boot device into fastboot mode and issue the following command to install:
sudo fastboot -i 0x1949 flash recovery <recovery-image>
Will check back in 5-6 hours on progress.

First one didn't work, second one put this out:
C:\adb>sudo fastboot -i 0x1949 flash recovery signed-thor-twrp-2870.img
'sudo' is not recognized as an internal or external command,
operable program or batch file.

This suggest the vulnerable bootloader was not properly installed. You will probably need to repeat the installation procedure from the point of placing the device in 'bulk' mode. Be sure to pay attention to file indexes and file identifiers that follow "if=".
