Kindle Fire is stuck at boot screen, (no animation). Help!

Hello Everyone,
I will try to provide as much details as I can from what I remember.
Basically, I tried to ROOT my device and install TWRP. However, I messed it up the first time. I tinkered with it for hours but it still couldn't work until finally, after hard resetting for the unlimited time, it booted up.
The problem though, is that it wasn't rooted and TWRP wasn't installed when it came up so I tried it again. Second try, second time it was messed up. Annoyingly, I don't know what I did earlier to make it work. The second instance it happened is just like the first.
Just to be clear, this isn't the boot screen where the kindle fire logo is animated (has reflections). In my case, its the logo as is, stuck on the screen just like that. Tried hard resetting, doesn't work.
What do I know?
1) From my earlier experience, it has lesser to do with the system (PC, Mac) and drivers since I managed to get it boot up again without being connected the first time
2) If I do connect it to the PC, it says Cannot Start Device/Unable to Start Device. Code:10. That's it. Even if I reboot the device, its still the same.
3) If you connect it to the Mac, it is detected in system preferences. Problem though is that I tried using adb and just like its windows counterpart, there are no devices detected.
THOUHGTS:
1) I know I just have to get it to be recognized and I can change the bootmode. Something's telling me that its a boot mode problem only. In my earlier V3X phone, I used to TP (testpoint) if anyone's familiar with that, or shortcircuit the board to get it out of the 'loop'. Do we have that with the kindle fire?
2) What operating system would it be easiest to get the device detected. I'm hoping that if there's lesser complications with the device being detected by the computer, be it mac, linux or windows, I can change the bootmode. my technical instinct tells me it has something to do with boot mode.
What have I done already?
1. Let me see, I believe I tried hard resetting it for ALOT of times already
2. Reinstalled drivers on PC. Used both Android and Kindle Fire Utility drivers. Even checked the /android folder
3. I'm using a Nokia Micro-USB cable. I'm not sure if that has any impact on the device or its effectiveness but I will try to pick-up another cable today and post later.
I would really appreciate if anyone can help. It sucks that I tried this just after unboxing the unit. I haven't even tried doing anything on it yet.
If you can help, ANY help would be appreciated.
Thanks mate!

had the same
1. use computer (windows - in my case windows xp)
2. nokia cable is fine (i use it too)
3. use kf utility .6
is your kf recognized by the computer ? (adb device or composite adm device)
have you tried to shutdown and startup your computer ? (not restart)
the entry for 18D1 in adb_usb.ini is missing - had to add it
the other entries are allready in version .6 android_winusb.inf
if you have troubles to remove old drivers use this:
http://support.microsoft.com/kb/315539/en-us
unplug/replug and install the drivers from .6 from scratch
it's not needed to reboot the computer - works immediately
waiting to get your status ...

Did you solve your problem?
My kindle is recognized by my computer but it as either ADB device or Composite ADB device (depending on what drivers I use to install it). Problem is that it says Cannot start device. Code Error: 10. Tried shutting down/restarting PC, still the same.

updated my initial post again ... (ms-link)
yes solved it in minutes
make the additional entry in adb_usb.ini
use only the drivers from .6
i think best way is to disconnect the kf - uninstall all old drivers regarding adb device - connect kf - use only drivers from .6 utility - start utility - change bootmode - up again !
whats your status ?

0x18D1 -- is that what I'm supposed to add to adb_usb.ini?

yes exactly - the device changes between the two id's regarding the bootmode
and don't let the computer select the driver - select manually

Okay, so I followed the instructions to a T.
I followed the MS Link to remove all drivers and then plugged-in the kindle and installed it back again by specifically telling windows that 'I have a disk'. It still says Code 10.
If it would mean anything, I'm doing this on a virtual machine since the computers around me are all Windows 7s.

I did try this yesterday on Windows 7 but most guides I see do it on older versions. I will try again a little later. Thank you.

I tried it on Windows 7. Still the same error. Kindle is frozen and on Device Manager it says "This device cannot start. (Code 10)"

I ran into the exact problem yesterday. I thought I bricked my kindle. That was scary. Anyway, the problem is that you're stuck on fastboot, mode 4002 instead of a normal mode 4000.
Following rootzwiki.com/topic/12363-how-to-windows-install-twrp-20-on-your-kindle-fire/
You'll need to add a new vendor id (0x18d1). However, even with that the device still will not be recognized right away. Following another user's suggestion on that same thread, I let the battery drained out. Once that's done, reconnecting the Kindle will show up as simply "kindle" on the device manager instead of the normal "unrecognized device".
Then do the adb commands (even if it doesn't show any device attached)
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
Click to expand...
Click to collapse
Your device will reboot out of the stuck "kindle fire" logo screen. If your device goes dark after, it just means that the battery need to recharged first. Another scary moment for me. You can unplug and use the wall charger, much faster than charging by PC. After 5 - 10 minutes, you should get back to your normal screen. Then, just use the Kindle Utility to install TWRP.

Actually, the problem with mine is that it's detected. However, it shows up as Code:10, The device is unable to start.
Still, I'll try to drain it first, tinker with it next and see what happens. That or I'll wait for tomorrow and open the whole device already and see if I can OMAP it.

Mine also did show up as code 10, and sometimes code 43 ... I tried uninstalled the driver and reinstall it manually each time and eventually showed up as unrecognized ... so I tried the battery drain ... I even tried putting it in the freezer to quicken the drain but not sure if it actually help ..

I tried the battery draining. Nope, still didn't work
UPDATE: I take this back. After draining the battery, I would like to confirm that the issue has been fixed. Thank you, THANK YOU Everyone! )
I REALLY APPRECIATE THE EFFORT. HAPPY HOLIDAYS! )

A family member recently got a Kindle Fire, I tried to flash recovery but it got stuck in fastboot mode. Windows will recognize it as uknown device but Linux won't detect anything in fastboot or adb.
I will try battery drain out since kaswistry said it worked
If all else fails, I will try this.. http://forum.xda-developers.com/showthread.php?t=1405052

can anybody help me?
*sorry for my bad english*

Could it be that something destroyed my FireFireFire boot? My KF always gets stuck in fastboot when I try to flash ... obviously quite annoying.

u guys need to talk to vashypool in irc and he can fix it!! he fixed mine and mine was a complete brick

If it gets stuck in fastboot you need to run the command fastboot idme bootmode 4000 from the Android SDK.

[SOLVED] Stuck at the KF logo

I seriously need some help. My normally fierce Google-fu has failed me. I have searched countless threads on here (and elsewhere) and tried just as many solutions, but I haven't had any luck. My Kindle Fire is stuck at the "Kindle Fire" boot logo. I was using the KF utility, and ADB status was online, everything looked good. I chose the option to root and install TWRP. However, it couldn't grab TWRP through my corporate firewall/proxy, so it skipped it, placed my KF in fastboot (I think), rebooted, now I'm bricked.
Depending on which PC I use, and in what order it's plugged in, I get different results in the Device Manager (both Windows 7):
Home PC -
Hardware Ids = USB\UNKNOWN
Yes, I've tried loading drivers six ways from Sunday, and none worked.
Absolutely no solution involving ADB in any way will work until I can at least get Windows to recognize it correctly and load the proper drivers.
Work PC -
If I have the KF turned on when I plug it into my PC, I get the same result as on my home PC (though I don't think I tried plugging it in on my home PC while my KF was powered off).
If I have it turned off when I plug it in, my PC sees it as an "Android ADB Interface", with the correct hardware ids.
Even when it sees my KF correctly in Device Manager, I still can't get ADB to communicate with it.
I've tried FireKit on my Ubunutu 12.04 laptop, but it never sees my device, and gets stuck at the <waiting for device> message. I've tried countless driver iterations and many utilities, and none seem able to communicate with it while it's stuck at the logo.
Any help would be immeasurably appreciated!!
[UPDATE]
While my device was detected correctly in Device Manager (but still not able to communicate via ADB), I reloaded the drivers using the KF Utility. It is still detected as "Android ADB Interface" but with an error in Device Manager. The error is "This device cannot start. (Code10)". I uninstalled it, including drivers, and let Windows autodetect. It was identified as "kindle", so I ran the same driver package and it still sees it as "Android ADB Interface", but still with the error.
[UPDATE 2] - Steps I took to (finally) get mine working
Note: If your device is recognized in Device Manager as something *other* than "Unknown Device* (such as "kindle" or "Android ADB Interface"), skip to step 3.
1. Turn off the device.
2. Plug the device into USB to your computer. This should turn the device on.
3. Delete the ".android" folder from your Windows profile. This is very important. If you just uninstall the device and driver, Windows will still use this to reinstall the device. You want to start as fresh as possible to eliminate complications from previous attempts.
4. Uninstall it from Device Manager. Make certain to check the box to uninstall the driver as well.
5. Start a new scan for hardware changes in the Device Manager.
6. As mine was stuck in fastboot mode, it recognized the device as "kindle" (lower-case "k")
7. Run the "install_driver.bat" from the Kindle Fire Utility.
8. After driver install, run the Kindle Fire Utility.
9. ADB status will say "offline", that's fine.
10. Choose option 1 to go into the Bootmode Menu.
11. Choose option 1 to boot into Normal Mode.
12. It will be stuck at <waiting for device>.
13. Turn off the device, keeping it plugged into the PC. *very important* This step was one among others that made THE difference for me.
14. Turn on the device. *Hopefully*, you should immediately see the utility spit out some text and your device should reboot.
15. Boots up!! (well, mine did, and I had almost give up hope were it not for my pride and stubbornness).

with emphasis on device drivers.
"Android ADB Device" typically means the device is in fastboot mode and you cannot use adb while in fastboot mode.... you must use fastboot.
With your KF off and disconnected from your work computer, run this command...
Code:
fastboot -i 0x1949 getvar product
and then connect it to the computer. The KF will turn on automatically. The computer will say "<waiting for device>" for a bit, but if the command works, it will eventually return "product: kindle" as output. If that works, you can actually flash TWRP from there, but if you are anxious for it to do something again...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
should get it booting normally again. If it doesn't, look at the link I gave you and focus on getting your drivers fixed. You won't be able to execute any commands (fastboot or adb) through Windows if the device drivers don't work. You might want to go back to Firekit if drivers remain problematic for you.
Everything you need to know to fix your KF is in that link at the beginning of my post, including the commands you need to run. At the bottom of post #3 is also another link to a how-to root/install ROMs page.

IT LIVES!!! While I was still getting the error code 10, I launched the KF utility one more time. ADB status was still offline. I went into the menu to modify boot mode, told it to boot in normal mode and it was stuck <waiting for device>. On a whim, I left it there and cycled power on my KF. It found the device, finished, rebooted, and it's good!!! The Device Manager is happy now too!!
The behavior was so odd between my work and home PC. I was seriously scared when it gave a bad device ids on my home PC. I think it was more a combination of several different things that helped, and I'll update my main post with all that I did to get it back (that I can remember). Hopefully it will help someone else.
This is an *amazing* community, and I can't thank everyone enough for the incredible work you all do and the true sense of selflessness exhibited here on the forums!
btw, How do I edit the subject to indicate it's solved?

Yes this saved two bricked kindles. Trial and error is sometimes the best means to solving a problem.

Stuck at the KF logo
These steps still didn't work for me :-/ I'm still stuck with the KF logo and a "Waiting for device" prompt. I've read through these forums starting with the "KKFB" to this one and still haven't had any luck yet. It may be time to give up on her. I think I have royally messed her up.
If anyone else has any other suggestions I'm open i've tried everything else on here I can find.

Agreed, you really need to be more specific. "Waiting for device" .... which part of the KF utility?. What *exactly* are you seeing, where? What does Device Manager show your KF identified as (keep in mind, there is a big difference between seeing it as "Kindle" and "kindle"). What *exactly* did you do that brought you to this point?
Symptoms. Symptoms. Symptoms. The more detail you provide, the more likelihood we can help.
Take heart. If there's anything I learned in my stubborn refusal to admit my KF was fully bricked, is that it can be brought back from a lot worse than we give it credit for. I also learned quite a bit that I never would have if I never failed. That's what I love about breaking things!

Okay, I was attempting to load a ROM on it. It had been rooted already with no issues and then something happened during the installation of TWRP and spit out an error message of unable to load and then rebooted. That's where I am with the kindle fire boot screen.
As for the "Device Manager" It shows up as "Android Composite ADB Device" and with KFU it shows the following status:
ADB Status: Online
Boot Status: Unknown
At this point is when if I try to run Install Latest TWRP Recovery or FFFF or anything it just sits there and says "Waiting For Device"...
I've read though most of these posts and have tried several different suggestions with no luck so far. So I have actually read through here. :-/
Hope this helps at all.

I would try by trying to change the bootmode using the KF utility. If you're stuck at the KF logo on boot, then the other functions of the utility won't do anything. Your KF needs to be in a "usable" state before that can happen. Have you tried changing it to "Fastboot" or "Normal"?

I presume if any of this helped, you were able to get further than you have been. What state is it in now? What error(s) if any?

I seem to be having this same issue but I cannot get my pc to recoginze the kindle fire as anything. perhaps i did something wrong but i was following a video on youtube and though i was doing it exactly as it showed. First thing i did after I finally got the drivers loaded was start KFU and then chose to load TWRP. It started the process but when it hit the part about rebooting my device that's where it stopped. Since then i've been stuck at the white and yellow kindle fire logo. No matter what i do to try to reinstall the ADB drivers I cannot get my computer (win xp) to recognize the kindle. It shows as "unknown device" in device manager and when it's plugged in the little pop up says that the usb device has malfunctioned and windows doesn't recognize it. So am I totally dead? I'm assuming before i can do anything to recover it I need to get windows to recognize it with the ADB drivers.

[Q] Kindle Fire is unknown device

Hi, I'm stuck in twrp bootloop. When I connect my kindle to PC (Win7) sometimes it shows unkown device and sometime nothing happens. I've searched the web for solutions for 4 weeks and nothing helped me. I tried mount USB storage in twrp, nothing happens. I just want my PC (Win7) to recognize my kindle, then I will follow the instructions from other threads.
*I have a factory cable.
**If you need more information,tell me.

What do you mean by twrp bootloop? Does it keep booting into TWRP over and over?
You're most likely experiencing a driver issue. Try to follow the directions here: http://forum.xda-developers.com/showpost.php?p=23747671&postcount=2 and see if it helps any. Just having the KF show up on the device manager is a good step forward, even if mounting usb storage isn't working.

Are you stuck in FFF or TWRP? What color is the Logo?

Have you tried plugging in the KF, uninstalling every single driver relating to Android (even samsung android drivers!), the KF, restarting the computer, and then running install_drivers.bat included in KFU?
The bootloop is very easy to fix - you're most likely stuck in the Recovery bootmode (5001), so having fastboot or ADB set your bootmode to Normal (4000) will solve it, but first you need to sort out ADB/fastboot, which are showing a drivers problem.
As a side note, this probably happened because you are using an outdated FFF/TWRP. When this is fixed, it's in your best interest to update to the latest version of each (1.4a, 2.1.1 respectively).

TWRP 2.0 included FFF, so you can use fastboot -
Issue "fastboot getvar product" and then plug in the KF, see if the fastboot driver is working. Otherwise, you're stuck on a driver problem again.
If it does list one device, then you can go with "fastboot oem idme bootmode 4000" and then "fastboot reboot". That should get you back on Normal bootmode and out of the TWRP bootloop.
Next would be updating both TWRP and FFF to prevent this from happening again, but there's the pending driver issue. I can't really add much more, other than carefully going through the post linked earlier, step by step.

Means you have a driver problem, which takes us back to the starting point. Can't do anything else until you manage to get the drivers installed properly, sorry. Alternatively, you can, on a different computer, download KFU and then run install_drivers.bat BEFORE you plug in the KF for the first time.

I tried nothing happened.

If you are doing flashes and nothing is working go to mount and make sure there are no checks in the boxes for system and data if so remove them then reflash or restore a backup after restore or reflashing a rom go back and check to make sure those boxes still have no check inside them then reboot I have had frequent errors like this when flashing roms that have the gapp package prebaked into the rom I do not have this issue when flashing gapps seperately

I found that from 20% - 80% battery it takes 12 hours

KFU Failed, Now Kindle Fire Won't Boot

Hello everyone,
I've tried to find my specific situation in related threads, but haven't seen my exact issue, so here goes. Several threads seemed to talk about what I'm seeing, but the remedies that worked for them have not worked for me.
I have a Kindle Fire running 6.3.1, and I tried rooting yesterday with Kindle Fire Utilities 0.9.6 on a Windows Vista Virtual Machine.
The drivers appeared to install correctly, because KFU was able to see the Kindle and showed "online" when I started the process. The Device Manager seemed to have the correct information as well.
In KFU, I selected option 2 from the main menu, to "Install Permanent Root with Superuser". KFU started downloading twrp.img, but was unhappy with the MD5 checksum, so it issued the error: "Oops... something went wrong with the download. The recovery downloaded is not correct. Please try the download again"
At this point, the run.bat program exited, and the Kindle rebooted.
However, it appears that KFU at least partially succeeded in putting the Kindle into fastboot mode, because now I just get the "Kindle Fire" orange and white logo and nothing else happens. Also, I can no longer access the Kindle from my computer.
Now, when I run KFU again, it can't find the Kindle. I also can't contact it by running adb or fastboot manually, either from Window or from Ubuntu.
I've tried most, if not all, of the tricks I've seen in related threads to get back into contact with the Kindle and restore it to normal boot mode. The fastboot executable gets stuck in the < waiting for device > state, and I've tried power-cycling the Kindle, unplugging and plugging it back in, timing the execution of fastboot with the startup screen, etc. Since KFU did not successfully install Fire Fire Fire or TWRP before the failure occurred, I can't use either of these to recover.
I have ordered a Factory Cable from SkOrPn, but I'm curious if there's anything else I can try before it arrives, or if maybe I've missed something in all of the reading I've done over the past couple of weeks. (I read many threads and posts about rooting the Kindle, along with the Beginners Guide, before I worked up the courage to actually try it yesterday, and since then I've been educating myself on recovery techniques).
Sorry for the lengthy post, thanks for any help or clues, and I apologize if this has been answered already in another thread.

You might try powering it down completely, run KFU, choose option 1, then choose normal boot mode (4000) and when it comes up with <waiting for device> then hit the power button on your Fire.
This has worked for me in getting it back to normal boot when things seemed to be hung up. I sometimes had to hold the power button down to hard shutdown after this, but when rebooted after that, it booted normally.
Can't hurt to try it in this case.

You say you're using a VM, but what OS are you typically running? Mac OSX and Linux both handle device drivers by far better than their MS counterparts.

spfldcynic - Thanks for the tip. I tried it, but never got past the < waiting for device > state. It makes me wonder if the Kindle is really in fastboot, or if it's in some other state that makes it unresponsive to external commands. Hopefully the Factory Cable will fix this.
soupmagnet - My host OS is Ubuntu 10.04. I'd like to be able to work with the Kindle directly in Linux, but went the Window route initially because I'd heard good things about KFU. After reading your post, I found the FireKit tools for Linux, but got the same results using the "normal_boot" script that I had with KFU and with directly issuing the "fastboot -i 0x1949 oem idme bootmode normal" command from both Linux and Windows.

Did you try the whole process from scratch on Ubuntu? Also, plug it into the wall charger and make sure it has some juice before continuing (if you haven't already)
Running low on ideas man, hope someone else can do more for you.

You can't just get up and go with Linux, there is some configuration that needs to be done first. Have you set up your udev rules and installed 32-bit libs?

Yes, after reading your post I've discovered that you are correct. I followed Sblood86's instructions on setting up the udev rules (http://forum.xda-developers.com/showthread.php?p=22067293), and I already had the 32-bit libraries and tools since I have the android sdk and a 32-bit Ubuntu installation.
Armed with this correct configuration, I typed
Code:
"./fastboot -i 0x1949 oem idme bootmode 4000"
And this time, saw the following:
Code:
< waiting for device >
...
OKAY [ 0.201s]
finished. total time: 0.201s
Meaning that all is now well with my Kindle Fire, until the next rooting attempt.
Thanks for your help!
So, although the original KFU problem is not completely understood by me, since my Kindle is working, I'll say the problem is solved.

[Q] Kindle Fire 8.9 Perma-Bricked?

Hey Guys,
I successfully rooted my kindle fire 8.9" a while back and a few days ago decided to follow: http://forum.xda-developers.com/showthread.php?t=2277105 to install the twrp/custom rom.
In fireflash I moved the bootloader back to 8.1.4 and changed the boot and recovery partitions accordingly. I disabled the recovery auto update. I applied the changes and rebooted (I saw the red kindle fire letters and then it changed to the blue letters). It went into the TWRP screen at which point the guide told me to reboot. I found a "reboot to recovery" option and clicked it. Apparently, this was a very bad thing to do. The kindle boots to the Kindle Fire logo in red letters and stays there. it doesn't go blue and nothing moves. It stays that way until I turn it off.
It no longer will show up in Device Manager at all, but if I turn it on while plugged into the computer, the computer makes fast bump sounds like it sees the device for a second.The first time I plugged it into a different computer windows said it was trying to install a driver for "Jem-PVT-Prod-04" but then the driver installation failed and it doesn't show up in the device manager even with an exclamation mark.
Using different adb tools (Minimal adb and fastboot, kindle adb drivers, and android sdk) yields no response from the device even with a factory cable (which I purchased and arrived this morning). Fastboot just says < waiting for device > after the command "fastboot -i 0x1949 getvar product"
Adb kill-server followed by adb devices leads to a blank list of devices. (I also went into user/.android/ to change the adb_usb.ini file to 0x1949 (which it already was)
I tried KFHD SRT v2.1 http://forum.xda-developers.com/showthread.php?t=2011126 but it can't see the device either.
At this point, I don't know what can be done and am open to trying everything.

Just to confirm that you're doing it correctly...have you powered the device completely down, entered 'fastboot -i 0x1949 getvar product', and then turned the device on? And still no luck?
BTW, the factory cable will not work with the KFHD8.9 and can possibly damage it. Don't use it.

Correct, I tried fastboot with the kindle 8.9 off, on,off then on, and on then off. None of these does anything except sit and say < waiting for device >.
Thanks for the heads up on the factory cable. It didn't seem to do anything any different anyway but is unplugged now.

I've run into relatively the same problem with my HD8.9 several times while testing scripts but I've always been able to enable fastboot after rebooting using 'getvar product'. The difference in my case, is that I was always using Linux. You may want to set up a LiveUSB and install the SoupKit from the Dev section and try again to see if it makes a difference. SoupKit is not required, of course, but it is definitely recommended if you're not very familiar with Linux.

Are you running windows??? If you are.... when your kindle is powered down and you type in the fast boot commands, go into device ,manager and see if your kindle shows a yellow triangle next to it. Reply asap.

Brandonrz,
It does not show up in the Device manager when off, when I send fastboot commands, or when on. It will however show up as Jem-PVT-Prod-04 for ~1 second if I have device manager open and I turn on the kindle (regardless of whether or not a fastboot command was sent).
@soupmagnet,
my flashdrive was dead so I just picked up a new one. Putting linux on it now.

For those who may be in same situation here is what I did.
Go to device manager. For that second, try to Right click on Jem-PVT-08 and choose update driver software, then browse my computer for driver software, then let me pick from a list of device drivers on my computer. I moved down list and picked Kindle and it installed as adb composite interface or something like that. Once installed the device manager showed "Kindle" and my fastboot was working. I've had the issue before. I hope this helped!

Glorious Success!
So I ended up doing a combination of the two solutions and since I know how frustrating this was here's how I did it just in case someone stumbles upon this.
How it magically worked:
1.) Inside of Linux Mint, I installed Soupkit
2.) In terminal i typed "fastboot -i 0x1949 getvar product"
-----The kindle reacted for the first time in a long time and went into fasboot mode. Since I had no idea where to put the boot.img or recovery.img in linux to send them but the fastboot or adb commands, I decided to risk it and move to windows.
3.) I unplugged the kindle
4.) Booted into Win 7 x64
5.) The fastboot wasn't working in windows but I checked device manager and the exclamation mark was lingering. I manually picked the driver of amazon.com/kindle and it installed the adb composite device. Fastboot now works in windows.
5.) ran SR Tool.bat in the KFHD_SRT_2.1 folder and chose option 1 (Enable Fastboot)
-----Success
6.)in SR Tool i chose option 4 (erase cache and userdata)
----Took ~4 minutes but success
7.) in cmd I navigated to my sdk platform tools folder by typing "cd C:\Users\<username>\Desktop\SDK\adt-bundle-windows-x86_64-20130522\sdk\platform-tools"
8.) I downloaded the boot.img and recovery.img linked here (http://forum.xda-developers.com/showthread.php?t=2011126) and placed them into C:\Users\<username>\Desktop\SDK\adt-bundle-windows-x86_64-20130522\sdk\platform-tools\
9.) in the cmd from step 7 I sent the following commands "fastboot -i 0x1949 flash boot boot.img" and "fastboot -i 0x1949 flash recovery recovery.img"
----Great Success
10.) In SR Tool I chose option 6 (reboot normally)
-----It looped for ~2 minutes but eventually booted like normal but the SR_Tool asked me to make sure that adb was enabled before clicking enter. I enabled it on the device but SR Tool still didn't seem to see that I had done it. Since it rebooted normally, I didn't really care.
11.) The kindle upgraded itself after I set it down to type this response to 8.4.3
I probably could have easily done this is linux, but I didn't know where to put the boot.img and recovery.img. Also, I'm guessing that the system.img is put back on the device when I used the KFHD SRT but I'm not sure.
Now I'm going for round two to get CM 10.1 put on this thing!
Thanks for all of the help. I really thought that I had actually managed to brick the nearly unbrickable kindle fire 8.9"

Congrats on your success and thanks for sharing the experience!
I think one problem with Windows is that, "fastboot -i 0x1949 getvar product" does not work very well on putting the kindle to fastboot if the device driver is not properly installed, kindle will simply bypass the fastboot step and continue(and hang), the whole situation is a dead loop on Windows if the fastboot driver is having problem and the kindle can't boot into the ROM, and to make things even worse, there is no factory cable for HD8.9
So the SoupKit is a real life saver here.

I had the same sort of driver problem after I installed the second bootloader. For me the simple fix was to go into device manager (In Windows 7), uninstall whatever driver was there with the yellow triangle and then reinstall the official kindle adb driver. Congrats on getting it fixed though. It's a great feeling, I know.

Worked form me too!

Thanks much for your pointer. In my case the Kindle showed up as an "Other devices" and I was able to use "browse my computer ..."->"let me pick from a list"->Kindle fire->ADB(ver 1.3).
You are awesome.

Turned out it was a driver compatibility issue with Windows 10. It doesn't recognize the Kindle HD 8.9 properly. Moved it over to a Windows 7 machine and it was working, up until i attempted to flash a new recovery and boot .img . Now it's stuck on the red Kindle logo and computer won't pick up the USB. Halp!

Power off the Kindle, type fastboot -i 0x1949 getvar product , plug in the Kindle when you get <waiting for device>, and flash the 2nd bootloader, recovery, and freedom-boot images as directed in Hashcode's thread. Skip to step 5 after downloading the files, as we're already in fastboot mode at this point.
Also, Windows 10 enforces driver signatures, so you'll need to disable that before proceeding with the Kindle driver installation.
