Same thing here. Any ideas on how to recover?

do you recovery your kindle fire?
sorry, i'm not here long time....

I think you don't need to install OMAP driver. I have been fixed my bricked device (KF HD 8.9) today.
How it became bricked.
I rooted it yesterday, than installed all Google apps and got strange issue in gapps framework. I started to delete some google apps and .odex files and my device stopped to boot correctly. It boots into recovery and recommend to reset to the factory mode. However this trick is not successful. So I have had boot logo looping.
How I fixed it.
I tried a lot of drivers and tricks to boot my KF into recovery. I even ordered the factory cable today on eBay, but I didn't want to wait about two weeks when it will be arrived to me. So I found working driver in Android SDK and Amazon Extension, like it described here: https://developer.amazon.com/sdk/fire/connect-adb.html . Than I used Kindle FIre Utility to run fastboot and adb tools. Also I downloaded KFHD System.img Recovery Tool to download the latest system.img and flash it in fastboot mode.
1. Download ADB (and Fastboot) drivers from http://forum.xda-developers.com/showthread.php?t=1890413 and install it (I used KindleDrivers.exe setup file)
2. Start downloading the KFHD System.img Recovery Tool from here: http://forum.xda-developers.com/showthread.php?t=2011126
3. Download Kindle FIre Utility from here: http://forum.xda-developers.com/showthread.php?t=1399889
4. Extract Kindle FIre Utility and run cmd.exe with with working folder Kindle Fire Utility\tools
5. Run this command:
fastboot -i 0x1949 reboot-bootloader (it will be wait while your device will be turned on in to fastboot)
6. Power off your device (hold power button more than 10s)
6. Connect your it to the PC
7. Power on it. And install drivers manually, choosing .inf file from the destination path where KindleSetup.exe was installed before. If you done steps above without mistakes, then fastboot.exe found your device during powering on for 0.5s approximately and switch it into bootloader mode (it means permanent fastboot in our case).
8. Now in fastboot mode it is possible to refllash some .img files. So extract downloaded earlier KFHD System.img Recovery Tool and flash system.img using this command:
fastboot -i 0x1949 flash system <system.img> .
9. When flashing will be finished you should erase userdata and cache using this commands:
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
10. And then boot the device again in normal mode using this command:
fastboot -i 0x1949 reboot
Now can load KFHD 8.9 without errors and than using adb tool to do other tricks.

Please Explain Red Wipe Screen

I have tried several times to get CM 10.1 installed on my Kindle Fire 8.9 and every time I get the red wipe screen trying to install the 2nd boot loader. After searching through the forums I have not found a definitive explanation (not that its not out there, but i didn't find one) of what causes the red screen, just how to recover from it.
I have tried using HashCode's process
http://forum.xda-developers.com/showthread.php?t=2128175
and also Option (41) in KFFirstAide
Can someone please explain what the red wipe screen indicates on the Kindle Fire 8.9, so I can avoid it and get the 2nd boot loader installed?
My Kindle is currently running Version 8.1.4 installed from the latest KFFirstAide (option 7). I have successfully rooted the device and I have been able to recover after the red screen each time.
Device Status before attempting to install 2nd boot loader
- Rooted using B4nary's Tool (v18.5.1)
- Erased Kindle Cache and User Data
- Enabled ADB on Kindle
- Enabled Allow 3rd party software

I used this tool KFHD_SRTv2.1- 8.1.4 To get into fastboot when I had the solid red screen then used option 7 to completely wipe and restore their is probably another way to just do the boot but it did work for me (did it today even)
Turn the kindle off (hold power down)
Load the KFHD_SRTv2.1- 8.1.4 tool using run as administrator
then use option 1
once your kindle says its in fastboot then close that utility and run the First aid

I know you said you aren't on 8.3, but it sounds like the bootloader issue Hash talks about in step 4.5 of his post. You could try flashing the bootloader he posts in that step to see if that fixes your issue. I had the same problem, until I flashed it.
Just an idea, I am in no way an expert just a tinkerer.

I too have the red screen, I tried to use the SRtool but was unsuccessful in recovering, can u provide anymore information? i'm really freaking out a little because i'm new to this stuff
I think fattire said Amazon enabled fastboot in this state. On KF2 and KFHD7, this is possible with a factory cable. I guess it's also possible that they have enabled the use of the factory cable for the KFHD8.9, but I'm only speculating.
Before the update, flashing unsigned boot and recovery partitions without the 2nd bootloader properly functioning, the device just wouldn't turn on. Now, not only will the device turn on, but some are even fixable in this state. I'm wondering if Amazon realized that wasn't cost effective to send every broken modified device to a specific secure location to get reflashed.
I don't quite remember what I did, but I was able to fix the "red wipe" screen on my Kindle 8.9.
I think I got this when I first tried installing 8.9StariROM when it was first posted on the forum. I did not know that the red screen could appear if TWRP was not installed already, and I think that's why I got the red screen error.
I didn't really know what it was all about, but somehow I was able to make my kindle go into the fastboot using this command (fastboot -i 0x1949 getvar product) and basically followed the instruction here: http://forum.xda-developers.com/showthread.php?t=2128175
I kept getting device not found error on ADB commands, so I skipped to STEP 4.5 and ran below commands in order: (of course, I downloaded all those files as well)
fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.3.0.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.4.4.0-recovery.img
then I think I ran fastboot -i 0x1949 flash system starirom-system.img to load the system image and I was able to have a working kindle 8.9 again.
I hope this helps.
Here is what I did to get myself out of trouble after screwing around with my KFHD 8.9 and getting a red screen (NOTE: I am assuming you have already installed the proper drivers so your PC can recognize the Kindle Fire HD):
1) Downloaded the above-mentioned KFHD SRT tool from here: https://docs.google.com/open?id=0B4lZEJI5lYeMR1YteUt2MGxZTGM) and the boot.img and recovery.img from here: https://drive.google.com/folderview?id=0B4lZEJI5lYeMNGdXMHI3T3pKM2c&usp=sharing
2) Unzipped the SRT tool into a folder on my Windows 7 boot drive (C:\KFHD_SRT_v2.1), and copied over the two .img files to the /images sub-folder.
3) Ran SR Tool.bat in Admin mode (right-click, Run As Administrator, click Yes to accept)
4) Turned off my Kindle by holding the power button 10 seconds until the screen was off
5) Chose option 1. Enable Fastboot, chose "n" when the tool asks if the device is turned on, then pressed the power button once on the Kindle to turn the screen on. VoilĂ , I was in Fastboot mode.
6) From a command line prompt (started in Admin mode as always), went to the /images sub-folder of the KFHD SRT tool and typed in the following commands, one at a time (just press Enter at the end of each, and wait until done):
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img (note: this may take a few minutes, depending on the speed of your USB port)
7) Still from the same command prompt, rebooted the tablet using the following command (type it in and press Enter):
fastboot -i 0x1949 reboot
I was back in business from there.
Can we get this as a sticky in the Dev Section? it took me 2 weeks to get my system back from a red screen that the below was able to do.

[Q] how to remove custom recovery and 2nd boot loader

can someone help me remove custom recovery and the 2nd bootloader i have the stock amazon rom installed
Thanks in advance
Usually updating the stock ROM will do it, if you made backups of the partitions like the tutorials tell you to do you can simply reflash them in fastboot mode.

I told someone else to try updating to the latest amazon os using Amazon's manual update the other day to fix this but it for some reason didn't work... But if you download the latest amazon is and update it it should work, however if it doesn't and it boot loops, technically you can go into twrp and tell it to reboot to boot loader (fastboot) and pull the boot loader IMG and recovery IMG from Amazon's update zip file on your PC and flash them via fastboot. If you need me to elaborate any just ask.

do you know of any tutorials on this? i could not find anything and as u can see i dont know much about this stuff so it would be appreciated.

Wanna mention ahead of time, i am not responsible if you hard brick your kindle by doing this, i dont like messing with the kindles bootloader unless i have to personally.
Ok follow the instruction on Amazon's Website for manually updating a kindle. This might either bootloop/go straight to recovery once you do this, if not your probably on stock unrooted without twrp or 2nd bootloader, usually you can tell pretty easily since the kindle logo would be blue if it wasn't stock, assuming that for some reason it either does bootloop/go straight to recovery or for some reason works but has twrp and second bootloader please read on.
Keep a copy of the update on your pc. Now this gets a bit more complicated because i realized the update is a bin file, but if i remember correctly it should just be a zip file, so either tell windows open with winrar or 7zip, winzip, etc, or try enabling file extensions in your folder options on windows, and changing the extension to .zip. Once you do that extract u-boot.bin and recovery.img from the recovery folder. Put your kindle into fastboot mode(hit reboot then bootloader in twrp). Now you need a copy of fastboot.exe, so use a utility like kindle fire first aid and remember to put the recovery.img and u-boot.bin into the folder with fastboot.exe. Open a command prompt and cd into the directory that the fastboot command is in (in kffa) and verify we have a connection to the kindles fastboot by running "fastboot -i 0x1949 getvar product"(if it hangs on waiting for device, open your task manager and update the driver for the device with a triangle next to it named jem with the drivers in my signature
.) Once that command can run successfully, run these three commands:
fastboot -i 0x1949 flash bootloader u-boot.bin
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 reboot
Now pray everything went well, because if your bootloader had a bad flash your going to have a hard brick. It should boot into stock os. Tada! I'm going to get soupemagnet to make sure i explained this correctly just to make sure i didn't miss something, you don't want to hard brick the kindle, that's a pain to even attempt to recover from without a major understanding of to solder and hookup an emmc to an sdcard reader.

Okay, let me stop you right there. There's no need to manually flash those images in fastboot and, as you are aware, it isn't the safest option.
To revert to stock (safely), download the appropriate software update for the device from Amazon (onto the device itself), rename it from update.bin to update.zip (very important), factory reset in recovery (extremely important), then install the update.zip in recovery.
Upon rebooting, there will no longer be a 2nd bootloader or custom recovery, and everything will have been reverted back to pure stock.
^^ what he said, I wasn't aware the amazon zip was compatible with twrp, it has files that a flashable zip tend to have but I never looked into it. Now I know something new for future reference. xD

did what you said but install failed so pushed cynagamod to it and installed now i am stuck on kindle logo cant do nothing not even boot to twrp.
Time for a fastboot mode and kffa... If you at some point installed the drivers for fastboot then this should go smoothly, if not you will have to keep your device manager open I. With does and update the unknown jem device that's detect to the drivers in my signature. Once you do manage to make sure that the jem device is detected and has its drivers installed turn the kindle off and unplug it, then on your PC run "fastboot -i 0x1949 getvar product", once it says waiting for device plug your kindle in. It should go into fastboot mode, once there use kindle fire first aid to restore the system partition.

lol i am so lost.
Basically you need to get a copy of kindle fire first aid from the 7" general section of the forum(yes I know it says 7" but its more liken all second generation kf's), open a command prompt as admin, and CD into the kindle fire first aid directory, run the command mentioned in my last post and plug the kindle in while its off. If it goes into fastboot mode then great, if not you have to install the fastboot mode drivers, you must open the device manager, and when you power on the kindle it should briefly show a jem device, you have to update its drivers to the ones in my signature before the device disappears. Once that is working run the command again. and do as previously mentioned.

Thank you so much for this solution. Although I get my 7HD to enter fastboot mode with cable - I can't get these other solutions to work.
In TWRP I REBOOT and see RECOVERY - but when I hit RECOVERY it just boots back to TWRP. Is that all I'm looking to do before going to INSTALL the .bin file (now renamed as .zip)???? thanks much...

[Q] TWRP flash failed but firefirefire installed, now I can't get to fastboot mode

I've been trying to root my Kindle Fire running 6.3.3. I bought a fastboot cable and got it to boot into fastboot mode to flash TWRP and firefirefire. I ran the commands and TWRP failed but firefirefire installed. Now when the kindle boots I get the firefirefire bootloader but it cant boot into the recovery because the TWRP never installed. Also, I can't get it to fastboot anymore, not even with the cable. Can anyone please help me get TWRP installed? I've read many forums and tried about everything I found.

FFF bootloader supports fastboot commands, but the flash command is now
fastboot flash recovery file name
ie drop the -i 0x1949
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.1-otter.img
because the fastboot mode window is short
with kindle connected to pc, power off kindle, enter commands, then power on kindle

I've been trying this for about 30 minutes or so with no luck...I even downloaded a different version of the twrp image. Do I have to wait for the fastboot screen to start the command or do I start the process before powering on the device? I'm not really sure what I'm doing wrong here.

Should be able to do it either way but I press enter, before the power button
This will not work if drivers are not correct
could try
Code:
fastboot devices
as a test should get something like
Code:
123456789 bootloader
back in command prompt
I finally got it to work and I can't thank you enough. You were right. I knew my computer recognized the device with adb in normal boot but my computer wouldn't recognize the device in fastboot mode until i reinstalled the android driver while it was in fastboot mode. Now I have a custom ROM running Google Play apps! Again, thank you!
Hey, I don't know if this will help others, but I had a hell of a time trying to get my kindle to recognize while in the bootloader/fastboot mode... It frustrated me so much that I had to write about it.
I recently switched to Windows 10, so it seems like my computer is relearning drivers and stuff...
My kindle was fine when on, and I could issue adb commands from the main screen, but when in fastboot mode, I couldn't get it detected. I knew the drivers were an issue, but I couldn't figure out how to do it. I looked at Amazon's support pages, went through the SDK route, tinkered with the adb.ini and so forth... to no avail.
Post after post said that the easiest way to install the drivers was through the Kindle Fire Utility, but for some reason, the drivers in the .bat file kept failing and would not load. It took a good few hours to figure out the solution.
When I asked the Web why the drivers kept failing, I came across a post that said Windows was actually blocking unknown drivers from loading onto my system. I really wish Windows had told me that instead of just saying "Fail"...
I had to hold down the shift button and click restart on the start menu, and when the computer restarted, I when through: troubleshoot -> advanced options -> startup settings and clicked on Restart. It eventually gave me the option to disable that signature verification [F7]
My explanation is crude, because I want you to look it up properly. Just search for "disable driver signature enforcement" and you should be fine.
Hope this helps others out. I may have to revisit my own post just to see how to do this again.

[Q] My fire won't exit fastboot

Hi, I was running CM11 on a rooted Kindle Fire HD 8.9 happily but decided to take the CM12 nightly and it's not gone well.
It installed but wasn't running correctly, here's where I made my mistake. Instead of waiting until I had a PC to hand, I did a factory reset on the kindle itself (i'm an idiot!).
Now, the kindle will start up into fastboot mode and take some commands but that's it. No recovery, no adb.
I have the android SDK installed along with google usb drivers and the amazon kindle usb drivers. The device appears on the PC (no yellow triangle, I'm running windows 8.1 and the driver is signed).
With fastboot, I can flash a boot and recovery image but I can't then restart the device in recovery mode or standard boot.
a fastboot reboot stays in fastboot mode. any volume and power button combinations won't take it into recovery.
i tried fastboot oem unlock but that doesn't get a response from the device.
I have the kindle SR tool utility (v 1.3.5). It can flash the images to the device but any attempt to reboot will always take it back into fastboot.
I've read countless articles but I'm now stuck. Have I killed my fire?
Thanks, Mike
"fastboot -i 0x1949 oem recovery" should reboot your kfhd into recovery. From there you can wipe system, recovery and data and re-install recovery, cm11 and gapps assuming the zip files are still on your device. Or you can erase and re-flash everything using fastboot commands. If all else fails you can first return it to stock KFHD OS using the system recovery tool. All you need is to get it into fastboot mode which it sounds like you can.

Hi, I was running CM11 on a rooted Kindle Fire HD 8.9 happily but decided to take the CM12 nightly and it's not gone well.

In my situation (Kindle fire HD 8.9 amazon OS 8.1.5) after install TWRP 2.6.0.0, the device is not loaded (always orange logo kindlefire at all) me helped Wipe> format data, after I then sent image cm-11 for devices, `adb push cm-11.zip /sdcard/`, and wipe cache and install cm-11 are successful.
Installing TWRP only for fastboot mode, in the fastboot mode `adb` command dont work, only `fastboot...........` command.
I hope something helped.

Fire HD 8.9" Stuck at Boot Screen, cannot connect fastboot or ADB

Hello all,
Recently recieved a Fire HD 8.9" (OS 8.5.1) from a family member that upgraded to a newer Fire HDX. I decided to convert the tablet to Pure Android to give it another lease on life, I followed the instructions here https://forum.xda-developers.com/ki...t-install-twrp-android-fire-os-8-5-1-t3278286 and I goofed. I forgot to "apply stack override" when flashing and when rebooting to go into TWRP it froze at the boot animation and will not connect to my PC (you can watch on device manager and it appears for less than 2 seconds before disconnecting). I have been out of the rooting and installing custom ROMs for a few years and I am lost as to what to do next. Fastboot and ADB commands are something I have not used before (I do have the latest Android SDK installed) using the command prompt doesn't scare me and I am used to fixing Windows OS issues using it. I have read a couple of threads saying to flash the factory system image to the device using fastboot but haven't found a step-by-step on exactly how to do so. I also have installed the driver for Kindle Fire HD 8.9" JEM found on XDA if that helps. TWRP is/was installed prior to rebooting, would just like to get back to where I can try again. This community has helped me a lot in the past when it has come to my Android devices.
Thank you,
Coop
I have the exact problem and and have been trying to find the solution for a week but nothing works. If I by chance find something I will come back and post it.

To go to fastboot - Shutdown your device.. and then make sure you have adb and fastboot installed in your pc/windows then type in
HTML:
fastboot devices
and hit enter. This should say <waiting for devices>
Then, connect your kindle hd to PC. It should show... fastboot mode
First make sure you have the correct device.. type the following... it should say ...jem
HTML:
fastboot -i 0x1949 getvar product
If you are able to get to fastboot mode.. if you have the stock image for boot, recovery, and system backups.. do the following
1.
HTML:
fastboot -i 0x1949 flash boot [your boot image file]
2.
HTML:
fastboot -i 0x1949 flash recovery [your recovery file]
3.
HTML:
fastboot -i 0x1949 flash system [your system/os file]
you should be able to restore to factory os.. Also, this worked for me in Mac.. had some issues using PC
I have the same situation and my Fire HD 8.9 is not detected by fastboot or adb.
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!!
just make sure you do
fastboot -i 0x1949 getvar product
in the CMD before you boot your device.
I made mistake of booting device then entering command prompt and couldn't get anywhere.
I also tried different usb ports.
also updated drivers on usb ports.
I used iobit driver booster 5 today and scan/installed outdated drivers. Maybe that helped.
plugging usb I noticed windows recognize something with word jem in it when I turned on device.
turned off tablet and retried and I got into fastboot.
again make sure fastboot -i 0x1949 getvar product is active in CMD before turning on tablet
