I just overall screwed up big time with this thing. I rooted 6.2.1, then uninstalled/froze a bunch of the stock apps (including the default Kindle launcher, as I had Go Launcher installed).
I then decided I wanted to restore to the factory default settings, as I wanted to use Amazon prime, among other things. I went into settings and hit the "restore to factory defaults button" (which was stupid, I know). Unsurprisingly, this resulted in Kindle Fire bootloops.
Trying to fix this, I used the KindleFireTool to install the most recent TWRP...which didn't work at all. It would just stay on the yellow triangle screen. Now, things have gotten even worse, though I don't know why. Whenever I plug the fire into the computer, it goes into TWRP bootloops!
For the brief few seconds that the Fire is on when plugged into my computer, the driver isn't recognized at all (shows up as "kindle" with a triangle next to it in device manager).
I know what I did was dumb, but even so, any help would be hugely appreciated.
YES YES YES!!!! OK HERES HOW I DID IT TO FIX THE BOOTLOOP OF TWRP
First you must download Kindle Fire Utility and extract it to your desktop
then go to command prompt or cmd then type in the location of the folder heres mine for example: C:\Users\Madaran\Desktop\Kindle Fire Utility\tools
then type in fastboot -i 0x1949 oem idme bootmode 4000
For me it said waiting for device all I did is rebooted the device and it worked
as the device reboot it will still go back to TWRP now type this in the command prompt
fastboot -i 0x1949 oem idme bootmode 4000
then it should reboot again and ITS FIXED
----------------------------------
I used this thread to fix it.

Thank you so much! I'll post results when I get the opportunity.
Well it didn't work...the thing isn't connecting to the computer properly. I think it's a goner.
Mine didn't connect also but it still worked. You don't need the device to be connected just plug it in and put it in the TWRP recover mode. Then do the steps again.
1.Download Kindle Fire Utility
2.Extract it to desktop.
3.You can't connect it while its in FastBoot mode so open up CMD or Command Prompt.
4.Again locate the folder and type it in the CMD for example I typed:
"cd C:\Users\Madaran\Desktop\Kindle Fire Utility\tools"
5.Then type this in "fastboot -i 0x1949 oem idme bootmode 4000"
6.It should say waiting for device. Go to TWRP and hit reboot system.
7.It should work now and while waiting for your Kindle to boot up, the power button should be orange.
8.When it turned orange I immediately typed this in the CMD or Command Prompt
"fastboot -i 0x1949 oem idme bootmode 4000" so it wouldn't boot to the TWRP recovery menu.
9.It should reboot again and load up your CyanogenMod 7
10. If it work hit the thanks button please.
I did all of that up until step 6. My device won't allow me to reboot. When it's plugged in via USB, it boots up, dies within 20 seconds, then boots again. I can't break the cycle, and it just says waiting for device on and on...

The reason your TWRP is boot looping is its because, you installed a file or zip that cause for your system to corrupt or break. It can also be a file that is in the system that you deleted and rebooted your Kindle to save changes.

Thats a great simple guide. One thing I want to add is that on my Windows 7 box, after I installed TWRP, the Kindle started being detected as "kindle" in lowercase and the drivers would not reinstall correctly, and if I manually installed them, the device would not start. I fixed this issue by doing standard USB device troubleshooting on Windows 7.
Open the Device Manager.
Expand Universal Serial Bus Controllers.
Locate all the USB Root Hubs and uninstall them by right clicking and selecting "Uninstall".
Do the same for all the controllers listed afterwards. Basically remove the USB Root Hubs first, then all the controllers listed so everything under the Universal Serial Bus Controllers is gone.
Reboot the machine and wait for the controllers and hubs to reinstall.
Then reconnect the kindle and hopefully the drivers will install correctly and allow ADB to connect.

Or one can just use firekit if they are new to this kind of thing and it works a lot like the kindle fire utility. Here is the link to my guide and the link for kindle fire kit is in there. I must warn those of you that are not on windows that this is a windows only program so those of you running different OS on their pc should either use this thread or my guide as well... Very nice thorough tutorial by the way!

Hey:
I am having this bootloop problem but when I use KFU 9.2 to get to normal the program just hangs with a white blinking cursor. Should I just wait or do I need an alternate solution. I have TWRP installed, I made a backup of my stock KF but when I crashed it and attempted to restore from TWRP there was no backed-up file to use.
I have downloaded the KF 6.2.1 upgrade using KFU but unsure how to install it at this point.
Thanks
maybe this one will solve your bootloop:

sirmavs,
I tried your last method and everything went fine until step 8. The light never turned orange and now I'm stuck on the Yellow Triangle.
EDIT:
At this point I opened up the Fire Utility.
I changed the bootmode to normal from there and CM7 rebooted fine.
I really do not understand why FireFireFire hasn't been updated to fix this?

Thanks!
This worked perfectly
Not quite sure what i did 0_o. I used the kindle fire utility to install permanent root. It rebooted and allwas well. Then i used the program to tell it to boot into fastboot mode. when I did this now it just loops between the Triangle and TWRP. Im guessing not screwed...i just dont know what to do next to fix it lol. I tried the brick fixer program. it just reboots the kindle fire and then it does the same thing over and over.
Try hooting into TWRP and telling it to reboot in normal mode.. using KFU of course lol.
I'm in the same boat...however, I figured out how to get it to stop and stay at the Triangle (fastboot mode)
I typed "fastboot -i 0x1949 getvar product" into the Command Prompt Window on my computer. It then said <waiting for device>
I forced the Kindle off with the 20-sec press, then unplugged and re-plugged it into the computer.
Now I just have to figure out how to get the fastboot mode to give me access to the USB, or to get ADB working on this sucker. I'm trying to get a ROM over to the Kindle's internal memory so I can save it's life!
Hopefully this will give you a launching place, too. Oh, and using the Kindle Fire Utility will then work as long as it's in the triangle screen, but every step I've used with it so far just puts me back into the FireFireFire / TWRP loop.
Hey guys thanks for the response. shortly after I posted this I went into the kindlefire irc channel and they helped me out. somehow the stock rom i was on corrupted itself and even when i did
adb shell
su
idme bootmode 4000
reboot
It still wasnt fixed. So the solution was to flash that modaco rom thats here and then run the adb command again. Viola. Working Kindle Fire . Now if i can just figure out how to make the stupid wallpapers stop auto cycling lol.

would try to boot to twrp, tap the mount button and mount sdcard
now you should be able to copy a rom to sdcard and install it
to force it to boot to recovery issue: "fastboot -i 0x1949 oem idme bootmode 5001" and "fastboot -i 0x1949 reboot"
if it says <waiting for device> just cold restart the kf - the command should be picked up and finished
don't forget to switch back to normal boot after installation: "adb shell idme bootmode 4000" and "adb reboot"
maybe this could also help you:

my kindle fire is stuck on the Kindle Fire screen, with no animation.
i have looked through XDA but could not find anything with my problem.
i do not have TWRP or FFF.
I'm running the stock rom.
kindle is not recognized on ADB.
i uninstalled the driver, but now computer management doesn't have anything for the device listed.
i used the kindle fire utility to install the drivers, still not listed on computer management.
it is recognized in the bottom right as plugged in as a 'android adb interface'
i have tried using the kindle unbrick utility, but it says there is no device plugged in.
EDIT:
i restarted my computer. now the kindle is listed as unknown device in the bottom right and in computer management.
i am still unable to install new driver software on it, though.
EDIT:
I tried using the driver from the .android download, it says that it's not going to work.
if someone could help me, please, it would be great.
EDIT::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
UPDATE TO THE PROBLEM::::
the kindle is still in the kindle fire boot screen brick.
it went from being an 'unidentified device' to being 'android adb interface'
the error code has switched from code 43 to code 10.
it says Device Cannot start (code 10)
it is not recognized by ADB
unbrick utility still doesn't recognize.

you can:

switch to normal boot:
use kfu option 1 - bootmode normal or manually (see above)
when it says <waiting for device> power off the kf by holding the pwr button for ~20sec till it turns off - pwr on again - the command should be resumed and finished - another pwr off/on should bring you back

Thanks so much I was having this same problem and have been bashing my head against the wall all day. This kind of thing is a little above my paygrade but I'm learning quickly!
It is stuck at the picture of yellow fire icon, with a phase press power button for recovery at the bottom...... but no matter how many times i press the power button, it does not respond..............helphelphelp.....
Try holding the power button for about 20 seconds, that should reset it. You can also try this: http://forum.xda-developers.com/showthread.php?t=1356257
Did you install a recovery yet? if so, try spam pressing the power button to get into it. From there you should be able to mount usb and install a rom
The kindle fire has several boot modes, one being a fastboot mode where it will stay at the bootloader until fastboot issues a command to change the boot mode. The command would be...
fastboot oem idme bootmode 4000 && fastboot reboot
not trying to be an ass but i wish people would learn some of the basics before jumping in head first into things they don't really understand then posting basic questions in the development section of forums
But my PC now cannot recognize my fire which is recognized as unknown device. Every time I tried to use adb shell, it said device is not found.....oh my god.....
And I have tried to hold the power button for more than 20s but it doesn't seem work.....
In fact I have installed TWRP once. However, when I am accidentally installing the TWRP twice, the fire is then stuck at the yellow triangle "FIRE" logo...and with a phase press power button for recovery at the bottom.
OH MY GOD....the Fire is my mum's ..... she is going to kill me

You might also need to use the -i switch. So the command would look something like...

MY fire relights its fire!!!!! so many thanks!!!!!!!!!!!
glad to help ...
please mark the subject of the topic (edit first post) with [Solved]
I solved it! it very easy:
1- plug your device to your PC while it is on fire icon
2- open "Kindle Fire Utility" and then press 5
3- done!
I was so scared that I had lost my kindle. I write this for others so hopefully will be helpful for them.
alright fellas, I had cm7 and twrp installed..everything was just DANDY and then i followed these steps to upgrade to miui ics build:
"...Step 3: Once transfer is complete, shut down your Kindle Fire.
Step 4: Boot into a custom recovery. ClockworkMod Recovery and TWRP are popular choices and you can choose to install whichever you like.
Step 5: Take a NANDROID backup. This may come handy later on if you have problems with MIUI and wish to revert back to current setup.
Step 6: Do a complete wipe & factory reset from the custom recovery.
Warning: This will delete all your personal data.
Step 7: Flash the ROM you transferred to your Kindle in Step 1. In CWM, you can do this from install zip from sdcard > choose zip from sdcard > [.zip file from Step 1]
Step 8: Wipe both cache and Dalvik cache.
Step 9: Reboot!"
after that Im stuck at the recovery yellow triangle, so i installed the kindle driver thats out there(shows up as android adb device after install) and now after driver install i boot the kf, it recognizes device, then disappears, then shows up, then is gone again. I cant push anything to the KF if it doesnt show up...i cant even quickly push something to it while its in device manager. Suggestions?
You need to use kfu to change boot mode to normal boot.
Or issue the following adb commands:
fastboot -i 0x1949 oem idme bootmode 4000
or
fastboot oem idme bootmode 4000
then fastboot reboot

i'm able to issue the command, reboot the fire and both commands work. However im still stuck at the yellow triangle
i'm able to issue the commands and it reboots. However im right back to recovery triangle
i'm able to issue the commands and it reboots. However im right back to recovery triangle
this worked
"- open a (elevated) command prompt and cd to c:\kfu\tools - leave it open all the time
- issue "fastboot -i 0x1949 oem idme bootmode 4002"
- it says <waiting for device>
- power off the kf by holding pwr ~20sec and power on again
- the kf is in fastboot now
- install twrp -> "fastboot -i 0x1949 boot twrp-blaze-2.0.0RC0.img"
- tap reboot on the kf screen
- update fff -> "fastboot -i 0x1949 flash bootloader u-boot.bin"
- reboot -> "fastboot reboot"
- restore to factory partitioning -> "fastboot oem format"
- boot to twrp -> "fastboot -i 0x1949 oem idme bootmode 5001"
- reboot -> "fastboot reboot"
- now the kf boots to twrp and adb commands are available
- test with "adb devices"
- open shell -> "adb shell"
- issue "echo /dev/block/mmcblk0p12 > /sys/devices/platform/usb_mass_storage/lun0/file"
- now the sdcard should mount to the computer
- windows will probably respond that the volume/device needs formatted before using it
- choose quick format and let it format it as fat32 block size 4096
- now you can download and copy your new rom to sdcard (ie prerooted stock)
- mount sdcard -> "mount /sdcard"
- exit adb shell -> "exit"
- tap install in twrp and install the new rom
- ignore errors about volume "misc" - the kf don't have a volume "misc"
- on the screen where you return after installation tap clear dalvik/cache
