I've read through hundreds of similar threads and haven't been able to find a solution - I'll gladly give up my firstborn (and/or make a paypal donation) to anyone who is able to help solve my issue!!
From my research, I seem to have no OS installed on the Kindle, and as far as I can tell, I'm booting into fastboot mode (screen hangs on the blue/white Kindle Fire logo, screen does not ever dim). I AM able to access TWRP Recovery, but don't have any backup to load from, am unable to successfully flash the ROM that I have saved to my SD card. My device manager recognizes the Kindle as a Kindle Fire (Android ADB Interface), no yellow triangles. Typing ADB Devices into Command Prompt gets me: [device number ] offline. Typing fastboot devices into Command Prompt gets me nothing (blank line).
Background/How I 'Bricked' It: I have a Kindle Fire 2 and was able to successfully unroot/flash Cyanogenmod 10 onto it. Worked perfectly for about 6 months, when I decided that it would be a good idea to flash back to stock so that I could give it to a relative. I have TWRP 2.3.3.0, so I used a guide on xda to do the following:
I used a guide from xda and followed these instructions
-Download latest KF2 stock software from amazon. Re-name the file to update.zip
-Moved it to the root of the SD card
-Booted in to TWRP
-Factory Wipe/Restore
-Wiped Cache
-Wiped Dalvik Cache
-Wiped System
-Installed the "update.zip"
-Wiped cache/dalvik again
-Rebooted
Unfortunately, wiping the system seems to have wiped the CM10 OS (ROM) that I had installed, and there was a failure in installing the amazon stock:
Installing '/sdcard/download/update.zip...
assert failed: is_substring ("Otter2 , file_getstring("/proc/product_name"))
E: Error in /sdcard/download/update.zip
(Status 7)
Error flashing zip '/sdcard/download/update.zip'
Updating partition details...
Trying to reboot the system from TWRP results in a message that states: "No OS installed! Are you sure you wish to reboot?"
Investigating using ADB: So it looks like I have no OS on the Kindle Fire 2. This seems to be a problem because without an OS, I am unable to use adb (from what I've read, no OS = no way to accept/authenticate the computer RSA fingerprint to whitelist the kindle and allow adb to function). Trying to use KFU, KFFirstAide, or the Kindle UnBrick Utility results in Error: Device offline or Error: Device not found types of messages (I am assuming due to the fact that I can't "turn" adb on by accepting the RSA fingerprint prompt)
What does Device Manager tell me? My computer can 'see' the Kindle Fire in device manager [as I stated earlier: My device manager recognizes the Kindle as a Kindle Fire (Android ADB Interface), no yellow triangles] but going to My Computer and looking under mass storage devices, the computer doesn't seem to recognize the device as a USB storage device, which is a problem because I can't drag/drop or push/pull files to the SD card so I can't try to flash anything *other* than the original file that failed.
Fastboot Mode...? From what I can tell (http://forum.xda-developers.com/showthread.php?t=1668159), my device is in fastboot mode. My Kindle screen hangs on the blue/white Kindle Fire logo screen, which from what I understand is hashcode's bootloader/fastboot screen. However, when I look at the Hardware IDs in the device manager, it tells me that my hardware IDs are:
USB\VID_1949&PID_0006&REV_0216
USB\VID_1949&PID_0006
So...my kindle seems to be stuck on the blue/white fastboot screen, but register on my computer as the stock kindle fastboot? I'm not really sure what's going on there, and couldn't find too many people with the same discrepancy that I have...
I tried plugging in my cord (making sure to use a USB 2.0 port), going into Command Prompt and using some fastboot commands. (ie: fastboot flash bootloader \path\update.zip) but all I get is a <waiting for device> for a LONG time. As in, a few hours. Some basic googling/investigation seems to indicate that I don't have fastboot drivers installed, OR that I wasn't running fastboot in an 'elevated mode' but I haven't been able to find too many details about how to fix those, IF that is the problem.
TWRP 2.3.3.0: I can get into TWRP recovery just fine, although I can't seem to figure out how to get files onto my device. So I've tried re-installing the original update.zip file that failed the first time several times, with no success. trying to 'Mount' the device doesn't seem to do anything (at least, my computer doesn't see the device as USB storage regardless of whether it's mounted or not) I tried using Advanced --> ADB Sideload, but trying to send the file in Command Prompt using the adb sideload <filename> command just gets me an Error: Device not Found message. I thought maybe I could try Advanced --> Terminal Command, but have no idea how to do that or what it does, and most sites are very vague about the step-by-step details, so I didn't really touch it.
Not sure if this is relevant or not, but when my KF2 is plugged into (attached) to my computer with the cord and is in TWRP, device manager shows the device under 'Other Devices' --> Amazon Kindle Fire2, and there is a yellow triangle on it. Not sure why...going back to 'fastboot' mode gets rid of yellow triangles and is recognized as a Kindle Fire again.
At this point - I'm pretty much stumped and have (hopefully) demonstrated that I've done my best to do my own research/read through threads/done due diligence. Is there anyone out there that might have any suggestions? Or do I now have a very large paperweight?
ANY input/suggestions/encouragement is welcome! I absolutely and sincerely appreciate your time in reading through this thread and trying to help noobs like me!
Use fast boot mode to recover to stock: http://forum.xda-developers.com/showthread.php?t=2096888
Or
If you have access to twrp. Use the ADb sideload feature to push CyanogenMod or another ROM over.
One thing though- if you can boot into TWRP you didn't wipe the system partition. Twrp for kf2 requires a file named stack to be there.

Trying to use the ADB sideload feature to push CM or another ROM over doesn't seem to be working for me (unless I'm doing it wrong?)
I tried using Advanced --> ADB Sideload, but trying to send the file in Command Prompt using the "adb sideload C:\users\Name\update.zip command just gets me an Error: Device not Found message". Could I be using the command incorrectly?
Trying to use any fastboot command in Windows Command Prompt results in <waiting for device> to hang for hours, with no changes to command prompt and no changes to the kindle (still sits at the blue/white boot logo).
Ah. Sorry. Missed that in the OP.
Sounds like you probably need the drivers installed.

Are there difference drivers for fastboot and adb? I don't get a 'yellow triangle' and my device manager identifies the device as a Kindle Fire [Android ADB Interface], so I thought I was okay.
Should I be looking for fastboot drivers?
And btw, thanks so much for your willingness to help and input!
ME TOO
Just purchased a KF from someone...thay had rooted it...I tried to unroot...got stuck...now mine is doing the same as yours. I hope someone has a fix for you as I too have a large paperweight.

tessa33,
I just sent you a response. Call me at 707-774-5923 when you have a moment.
Solution?
I figured I could post in this thread before staring my own because I am having a very similar issue trying to revert my Kindle Fire 2 back to stock from cyanogen so I can sell it. I downloaded the official software from Amazon but every time I try to flash it through TWRP I get the exact same error you were getting. Did anyone ever figure out how to resolve the issue for you?
Had the same problem, so I chatted with an Amazon associate, told him I turned it on one day and it showed the grey triangle and he sent me a new Kindle Fire 2nd Gen for free. Try that...

Hello
I have rooted KF2 and I did factory reset I lost TWRP&Os I can see the device as ADB device, Howeverm when the device in fastboot the pc not recognize it.
issuing fastboot devices command return nothing.
I used ubuntu and windows still the same issue. any idea?
I got a KFHD 2G (2013) from a friend and the problem was simple: when the lock screen came up, he couldn't enter in his passcode because the keyboard wouldn't show up. There was no way to get into ADB since I couldn't get in. I tried to do a factory reset via recovery, but there is no recovery. I built a fastboot cable and tried "fastboot -w" but the partitions could not be formatted. This device seems completely screwed, I trued grabbing the factory update from amazon, but it's in BIN format and won't flash in Fastboot. Inside the BIN file, it seems to just be a recovery-flashable zip, however, it will not boot into recovery so i can't install it. Fastboot reports that two .txt files are missing. I tried extracting recovery.img from the zip and booting it as a ramdisk, however, this just causes it to boot normally. I ended up flashing userdata with boot.img as a way of formatting it, which got the keyboard back, but puts it on a screen saying "Enter password to decrypt Kindle." The password, "LOVE" is not accepted and entering 4 incorrect codes does not prompt a format. I'm at a loss here, it seems like it's just nt possibe for this thing to be screwed completely, but im out of options. what should i do?
HELP!!!
Also, I just realized this thread should be in "7" Kindle Fire HD Q&A, Help & Troubleshooting"
Um so now it's to the point where it's asking to format it because the password is wrong so wouldn't that be the same as formatting it as you had intended on doing earlier? BTW fastboot commands on a kindle fire have to be prefixed with "fastboot -i 0x1949", also I don't know off hand if that command you were going to run is a user data wipe or a complete wipe and a complete wipe would been bad. So at this point if the lock screen asks you to format it and you don't have adb enabled then you probably will have to format it, I thought the new gen had adb access from early on in the boot process but I could be wrong, I suggest looking in the hdx section.

sadly, no adb, its not an HDX because it's only dualcore. i now need a system.img and userdata.img.. i flashed the img from the ADK for this device and now all i get is fastboot.. i need ripped imgs from an actual device. the command i was running was a userdata/cache wipe, and i did prefix it but fastboot couldnt format the partitions because the filesystem wasnt compatible. The lock screen flat out wouldnt ask me to format, and the back button never showed up, which leades me to believe the system image was corrupt too. if anyone can give me system.img and userdata.img i would be eternally grateful! thank you for replying
Ah I knew it wasn't an hdx but they some things on that device that are similar to the hdx, like I think they disabled some fastboot commands from working and such. Hopefully someone more familiar with 2nd gen hd's can help you out more.

Hi, I successfully rooted my KF HD 8.9 with instructions found here
http://androidroot.org/watch_video.php?v=A7HRK4M23YG7
But am now stuck in fastboot mode (displayed on screen). I did have twrp installed and got the blue logo, but not anymore.
I tried KF First Aid, under the option “Display Fastboot Status” I get
“product JEM-PVT-Prod-04
6498000040002FFF fastboot
If you see output above it looks like fastboot is enabled”
Device Manager shows under “Kindle Fire > Android ADB Interface”
Have I bricked my Kindle?
Any help greatly appreciated
Its not bricked, though I would attempt to restore the system partition with kffa since 2nd bootloader is gone. You should be in fastboot mode so that's good at least.

Thanks for advice, unfortunately I'm not clever enough to do that without step by step instructions, could you help me?

Download Kindle Fire First Aid, find the option about restoring, and if it asks something about is it in fastboot already say yes(or if it asks to put it in fastboot mode say no as it should be already).
tried that exactly as you said, everything seemed to go ok, but when it rebooted it sticks on the kindlefire (orange) logo
Try using SRT instead. Ignore the adb command it lists, that's only for if you have a working kindle that can boot up fully, just stick it in fastboot again and use this utility and see if you have any luck.

Hi, I've tried about 10 times to download KFHD_SRT_v2.0.zip which seems to be for my device, but it fails every time
with message ' the source file cannot be read'. I have downloaded KFHD_SRTv1.3.5.zip, which appears to be for the 7" kindle.
Can I use this, or will the imgs be wrong? There are 4 in the images folder, boot.img, recovery.img, system.img, and systym2.img
The 7" version is not for the 8.9 version, you would probably brick it even worse using that... The ones on that link I sent you are the compatible ones.
Sent from my Amazon Kindle Fire HD using Tapatalk
that is the one I'm having trouble with, KFHD_SRT_v2.1.zip. While in Kindle Fire First Aid I checked adb and got the message 'adb drivers not installed' so removed and re-installed adb drivers from Amazon, but I still get same message.
Since removing and re-installing drivers my device in device manager now only shows as 'Kindle fire > Fastboot Mode | HD 8.9. It used to say 'ADB Interface'
I think I flashed the wrong recovery (otter). Prior to doing so I had wiped /system. Now I'm stuck at the kindle fire logo with no apparent way to boot to anything functional.
On both linux and windows 'adb devices' shows the device is offline and the serial is 01234567890ABCDEF.
On both linux and windows 'fastboot devices' show no device.
I've tried using Kindle Fire Utility v.0.9.9 but since neither adb nor fastboot work it doesn't help
I've tried using Kindle Unbrick Utility v1.1 but it too fails to help in this case.
Is there any hope of recovering this device?
Thanks,

Thank you very much for the offer Josh. I was able to recover using a fastboot cable.
Initially I thought it did not work since I saw no difference on the screen and the command
Code:
fastboot devices
did not show any device. But I tried running
Code:
fastboot -i 0x1949 devices
and there it was. From there I booted into TWRP
Code:
fastboot -i 0x1949 boot openrecovery-twrp-2.7.0.1-blaze.img'
and installed CM11 M5.
Thanks again,

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
