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.

I'm new to this forum, so bear with me if I have created this in the wrong area.
I'm trying to un-brick a (I think 1st gen.) Kindle Fire HD with a Fastboot cable on a Mac.
All it does is stay at the KindleFire boot screen. At first I thought it was the battery so I replaced it but that didn't do the trick.
So, I got the fast boot cable and now I feel that I am lost within a sea of different methods and tool kits to try and get the device restored to factory settings.
I've gone through the process of downloading the Android SDK so I can get fastboot and adb.
When I connect the Kindle Fire to the fastboost USB to my Mac, it will go to the fastboot screen.
When I run
Code:
adb devices
it doesn't show that anything is connected.
However, if I run
Code:
fastboot -i 0x1949 getvar product
it appears that it's connected via fastboot:
Code:
product: Tate-PVT-08
finished. total time: 0.000s
But I'm kinda lost after that. Seems like most of the guides out have a slew of different options and boot loaders and I'm not sure which one will get back to the default factory settings. Most of what I've seen is that you need to enable ADB on the device, but since I can't boot into the device, I'm not too sure what I need to do to get it to reset.
I've read through this post: http://forum.xda-developers.com/showthread.php?t=1399889
but it says that it cannot recognize the device when I attempt to do this on Windows. And when I launch the device manager, it shows that it is connected as Kindle Fire as Android ADB Interface.

I think I found the correct thread to post this in, so I posted it in the Kindle fire section. So to any of the moderators out there, you can delete this thread. Sorry for the double post.
I am trying to install Cyanogenmod on my kindle fire. However, before I was able to start flashing any images or anything like that, I ran into a problem (although this is probably the best time to have a problem). My Kindle Fire HD 8.9 won't enter fastboot mode.
I'm running Windows 7.
I installed the android SDK.
I installed Amazon's drivers for the Kindle Fire.
When I type in "Adb drivers" into the command line, I get my serial number.
When I type in "fastboot drivers", I don't get anything back.
When I type in "fastboot -i 0x1949 getvar product" , I get "waiting for device", I plug in my Kindle Fire HD 8.9 (Edit: when it is off), but it just says at "waiting for device".
I've tried typing ""adb reboot-bootloader", but that reboots the device normally.
I've read that I don't need a fastboot cable for the Kindle Fire HD 8.9 (unlike the 7).
What am I doing wrong?
Power OFF
Have you tried connecting your Kindle while POWER OFF. (Pressing power button for 20 Sec)
Steps
1. Go to elevated command prompt (admin command window)
2. type "fastboot -i 0x1949 getvar product", "waiting for device" should display on screen
3. Power off Kindle (20 sec press of Power Button)
4. Connect kindle to PC
It should go into Fastboot mode.
This will work. Hit Thanks if I helped you.
Didn't work.

I'm in the slow lane now after trying numerous ways to root this 8.9 8.5.1 fire. Still not showing root but everything goes slow now.
Guess its better than a brick. Wonder if I can load a CM since my root failed.

Anyone figure this out? Having the same problem - won't boot into fastboot mode, just boots normally (with cable plugging in and fastboot waiting on the device). Adb also works fine.
Install android studio and get the drivers from that.
Same Problem on Kindle Fire 8.9 HD - Fastboot not work!
Hi,
I have the same problem. Adb works, fastboot doesn't work on my stock Kindle Fire HD 8.9" 2nd Generation. Here is my environment:
Windows 10 Pro x64 with latest MS Patches, Toshiba Patches, Intel Patches
BitDefender Anti Virus
ADB enabled on Kindle
Adb and fastboot Drivers installed via Android SDK
Kindle Driver install downloaded from Amazon
PC is new Toshiba Satellite P50W with USB 3.0
Drivers look okay in Device Manager
- Kindle Fire -> Driver = Android Composite ADB Interface provided by Amazon dated 12/3/2012
- Portable Devices / Kindle -> Driver =provided by Microsoft dated 6/21/2006
Symptoms:
ADB Commands work including adb kill-server, adb start-server, adb devices (returns Serial Number)
- Fastboot -i 0x1949 getvar product shows "waiting for device" in PC's CMD Window and never goes away
- I attach standard USB Cable to the Kindle that is currently Powered Down (not just sleeping) after issuing above command on PC
- Attaching USB Cable simply causes Kindle to power on and boot normally.
What I have unsuccessfully tried to date:.
Tried alternate commands:
- adb reboot bootloader (to start Fastboot)
- fastboot -1 0x1949 reboot (to exit Fastboot)
Tried USB 2.0 Port instead of 3.0 Port.
Tried reloading Kindle Drivers.
Trying Android Platform Tools Ver 23.1 RC1 instead of Ver 23.01
Tried two different "Standard" USB Cables, one Factory Cable by itself
Any Ideas? I've been trying to get FASTBOOT working so I can play with Cyanogenmod for a couple of days without any luck. Thanks.

Same
Having the same issues on 5.1.1 5th gen 8.9HD. zero fastboot....
I'm having the same issue. Has anyone found a solution or found another way to root the device with version 8.5.1_user_5159720 installed?
Hate the Kindle version of the OS. I want to install CM or LineageOS (If I can find a build for it!)
Thanks!

I did a bit more digging and found a tool that will root the device. You can find it at https://rootmaster.co Just download and install the APK on your device and allow it to root.

this is a COPY/PASTE of my own post. the files i specify are the exact names, just search this section of X-DA for them. SEE BELOW.
i had the same problem with the "red screen of death" as well. i found that if i installed the "Minimal ADB and Fastboot" and / OR (i did the minimal first.... ) KFHD_SRTv1.3.5 and RUN THE APP FIRST, then when it says "waiting for device" you then plug in the ALREADY OFF tablet it then WORKS!! says "fastboot mode" on the tablet. and it is listed in device manager also.
i got BOTH apps here at this board in this section.
WARNING: i run windows XP with all updates as of 10-31-2017 (pm me for info, 2 lines of text!! ) . NEWER windows versions have "permission issues". fixes are posted in multiple topics here in the Amazon 7" Kindle Fire HD, 8.9" Kindle Fire HD, Kindle Fire 2 section. READ THEM!!
Start by turning off tablet. type in "fastboot -i 0x1949 getvar product". Get (waiting for device) message. Plug USB into tablet.
Hi all,
I got a refurb 8.9 HD for basically free, so I want to flash the best current ROM onto it (which it looks like is CM11 at the moment). I'm having a bit of trouble getting the device into fastboot mode:
What I've accomplished so far:
Have adb and fastboot working in the command prompt
Installed the amazon usb drivers, kindle shows as Android Composite ADB Interface in device manager
Device is recognized by adb devices (shows serial number + "device")
Turned "Enable ADB" to ON in security settings
However, when I unplug the kindle, execute the "fastboot -i 0x1949 getvar product" command, I do get the <waiting for device> message, but when I plug in the turned-off Kindle, I get two quick chimes, then a second later the "device disconnected" sound, then the kindle boots as normally, and nothing happens in the command prompt.
It may be worth noting that when I first connected the Kindle (after installing drivers) I didn't get the "Enable USB Debugging" pop-up that two guides mentioned. Thoughts?
You must be doing it in the wrong order
1. turn of your kindle
2. connect your wire
3. open cmd and type fastboot -i 0x1949 getvar product
now it should show
< waiting for device >
4. now turn on your device it should go into fastboot
Did you get it to work? And are you running 8.5.1? Because that's what I'm running and I'm having the same problem. I've seen solutions all over the place for 8.4, nothing for 8.5. Amazon seems to have a real lockdown on it.
Hi Guys!
Picked up a refurb Kindle Fire HD 8.9 on Woot the other day and want to stick CM 12.1 on it. I'm no programmer but I've successfully followed directions to root and install CM on about a dozen devices over the years but this one has me stumped.
I'm running Windows 10 and have apparently successfully installed the Amazon USB driver. When the tablet is plugged in Device Manager shows "Fire Devices > Android Composite ADB Interface" and it reports "working properly." I made sure to install the driver with Windows driver signing OFF. I can do a command prompt "ADB devices" and I get back a single device which corresponds to the device Serial Number (when I disconnect the tablet, I get nothing). So it seems ADB can find the tablet. The tablet has "Enable ADB" set to ON. I have done nothing else with the tablet, no registration, nothing, it's direct from factory and seems to be working fine. Current system version is 8.4.3_user_4308820, I have not updated it from what it came with.
So everything looks good until I try to run fastboot. I punch in "fastboot -i 0x1949 getvar product" and get "waiting for device". I reboot the tablet and it just simply reboots like normal and brings up the lock screen. I can't get Fastboot to show. I've done a simple shut down/reboot, I've held the power button down for like 20 seconds and forced power off. I've also tried plugging into different USB ports and different USB cables. Still nothing, just "waiting for device".
Can anyone offer suggestions to get to Fastboot? Many thanks in advance!
Are you generating your command prompt in the folder where fastboot.exe (and ideally also adb.exe) is located? If not, do so. When you get the "waiting for device" prompt with fastboot, are you then plugging in your powered OFF Kindle? This is one way that fastboot operates in our Kindles. There is also the modified factory cable that will automatically reboot the Kindle into fastboot mode (see the following video: www (dot) youtube (dot) com/watch?v=FFoAvnf7YUQ). Alternatively, you can try using ADB to reboot the device into fastboot as shown in the video. Good luck!
