I have rooted several android phones and my fire when fired released. Lost root a few updates ago and finally want to root so I can place ICS on it. I am on 6.3 and have tried KFU 9.4 & 9.5 of 2 different computers and it when it runs run.bat it crashes.
Attempted doing CMD way but never tried that way before and prob doing something wrong.
Please help. I also restored fire to factory condition's in case previous old roots left files that are screwing it up...
Going bonkers....Rooted my Bionic this morning in 3 mins...been working no Fire for 3 hours....

This guide requires you to have adb and fastboot working FOR THE KINDLE FIRE,
How do you do that?
I am stuck at waiting for device when using KFU 9.5 , reinstalled drivers but nothing
Make a folder on yourC drive called KindleADB. Then copy the files from the tools folder in Kindle_Fire_Utility_v0.9.5. To the KindleADB folder you just made.
Also download the REQ files in the topic link I posted. Copy those files to the KindleADB folder as well cause you will need them.
If you got the driver installed like you say you do. You can just follow the steps and root the device.
I was having a similiar problem, what I had to do was plug in my kindle, and then uninstall the drivers. Then I would unplug and then plug back in and let the drivers reinstall. I also used kindle fire utility 0.9.4
ADB and Fastboot from the Kindle Fire Utility seems a little hit or miss. My desktop doesn't run any of the .bats so I was scared to try it there. My Mac in win 7 with bootcamp worked fine.
ADB and Fastboot were much easier to get working in OS X 10.7 and Linux.
When Kindle Fire Utility failed the first time I switch to OS X and did jcase's method to get root and install TWRP then i just flashed a custom rom.

How's it going everyone. I just want to thank everyone for all their help and for putting up with me the past few days. I've been bugging everyone with question after question on how to root my kindle. When I first got my Kindle I knew I wanted to root it and have access to the android market and eventually flash some new roms so I hoped right over to the XDA site. When I got on the site, I was a little overwhelmed with all the information out there on what to do and how to get started. I was reading things like the Burrito root, utility, twrp, ect...
Well, I thought I'd try and help anyone who is in the same boat I was in. I was finally able to root my kindle last night with the help Jayceooi.
The steps that I took and the steps that might be easiest for people new to rooting:
I used the Kindle Fire Utility v.9.1 to root my device, install twrp (which is used if you want to back up your system, flash a rom, restore back to stock, ect.. its recommended to install), and install the android market and go launcher. My thanks goes out to the Jcase and Vashypooh.
1.) Before you try and use the KFU v.9.1 make sure you have the ADB driver installed (properly) and is running when the kindle is connected to the PC
I used Jayceooi's and adb driver file link (not the one that comes in the KFU zip) to install my driver. On his guide he states - "Why not use install driver feature in Kindle Fire Utility? There is an issue on Kindle Fire Utility v0.9.1. It will replace Kindle Fire USB Mass Storage driver. So you can’t use USB Mass Storage mode anymore if you install driver with Kindle Fire Utility." (Might be why alot of people are having problems trying to root)
2.) Once the driver is installed, then run the KFU v.9.1 and selection option 3. Hit enter and the utility does the rest.
3.) Intall TWRP - plug kindle back in and run KFU v.9.1 and selection option 5. Hit enter again and the utility will do most of the work. Make sure you read everything during the installation and wait until you hit reboot and see the yellow triangle before you press a key to continue. (watch the video in the link below and you will see what I mean.)
4.) Next I installed the android market, google apps, go launcher from the Utility too. Like i said, that utility is tits! run the utility again and select option 6 (extras) then 2 and it will do the rest.
This may be a redundant thread and get pushed out and I know a lot of the experienced guys might laugh at how lame, but If I had something like this to follow it would have really helped me out and saved alot of time. The guide that Jayceooi does is really nice and easy to follow.
I think the the installation of the correct driver is the biggest thing and what causes the most problems for people. so if you get that right, you should be in good shape. just follow the guides and it shouldn't be to hard
Step 1.) Install Kindle Fire ADB usb driver - http://www.jayceooi.com/2011/12/29/how-to-install-kindle-fire-adb-usb-driver-video/
Step 2.) Root kindle - http://www.jayceooi.com/2011/12/29/how-to-root-kindle-fire-with-burritoroot-video/
Step 3.) Install TWRP - http://www.jayceooi.com/2011/12/29/how-to-install-twrp-2-0-recovery-on-kindle-fire-video/

I'm not really a noob per-say, been around a good while actually. But your point in this post about the correct driver and you bringing everything together for a very easy to follow guide really did help. Thanks!
I actually had a weird issue where I wasn't seeing a yellow triangle for the ADB driver and just couldn't get root to take. Updating it did the trick (It needs to say 'Android Composite ADB Interface')
Yay! My backup just finished and I'm not stuck with a yellow sign. Success.
just got my KF today and I'll try this out tomorrow when i can get to my friends windows computer (virtualbox on my Mac doesnt like me.....)

You should be able to use the KFU to install the android market. once your plug the kindle into the pc and the driver is installed properly, run KFU v.9.1 Select option 6 (extras) then select option 2 (Google apps / go launcher) KFU should do the rest. If you want to manually downloand use this link http://api.viglink.com/api/click?fo...t=Click Here&jsonp=vglnk_jsonp_13252517466081
for some reason my Mac wont recognize my KF and my VirtualBox Windows won't either so i have to wait for a bit....
EDIT: nevermind
next issue, whenever i go into the Devices and Printers menu and then to the Kindle and into Properties, it only lists USB Composite Device. Could this be because i am trying to do this on an Windows 7 VirtualBox setup and not through a true W7 computer?

stuck at triangle
Got the triangle screen and following instructions in guides are not fixing it. Heres my scenario. I got my kindle with 6.2 on it. Got it rooted, installed market and go launcher and was great. Then the update of course came thru and broke root. Still been able to download market apps and use go launcher. So I followed this guide to regain root and install twrp. It says root is successful, but superuser force closes everytime trying to open or use it. I can open my tibu and root explorer and everything still gave me root access. Went and changed the MarketIntentProxy.apk to MarketIntentProxy.apk.bak so market links go to market by default. That worked. Noticed that all amazon apps downloaded have a default amazon icon. Thought nothing of it. Went to install twrp anyway. Stuck at triangle now. Followed all instructions to fix and the KFU keeps flashing error device not found constantly and device status unknown. What happened?
Prior to 6.2.1 I had my Kindle Fire rooted with super one click. It seems like the Kindle Fire utility is the method of choice today. I would like to know if there is anything special I need to do to remove superoneclick and/or drivers before installing KFU. I'm trying to be a bit cautious here since the frequency of bricking seems to have gone up.
I was lucky that the 6.2.1 upgrade did not mess up my android market or google install – I had already upgraded to the latest version prior to the install. I would like to regain root, but I'm willing to go slow since my KF is currently rock solid and I don't really have any pressing need.
Thanks
Bruce
I didnt have any issues switching from one-click to KFU. it ran fine with the drivers i installed to use one-click. I did have one issue after installing the 6.2.1 udate and FFFm I had to reinstall the KF drivers after I updated (my windows box no longer recognized it and it got stuck in the wrong boot mode which was easy to fix from command line once it was recognized again).
Kekule
As far as I know SuperOneClick never installed anything on your Fire. It sounds like you are using a stock un-rooted 6.2.1 so you'd just proceed as any normal 6.2.1 user would. I, myself, rooted back in 6.2 with SuperOneClick and have been ever since because I installed TWRP and used the pre-rooted 6.2.1 image. I'm kind of curious if there's anything I need to know as well, though. I'd rather err on the side of caution as well.

nothing more that SU, but you do have to get ADB running which requires having the android SDK usb driver to connect to the fire instead of whatever gets installed by default.
Great.. just thought I would check before I just plowed ahead as if it was a brand new 6.2.1 KF. I'm not sure when I'll get to it, but it's nice to know that I don't need to do anything unusual. I may just wait a bit to give KFU some time to mature.

I don't think KFU is going to change much now. Its been at 0.9.1 for some time how. I see the links to the original article are backup so the links should be good too.

Kindle fire came today with stock 6.2.2 firmware. Kindle Fire utility doesnt recongnize the kindle. I update driver that came with it, now its recognized as an android phone and no way to unistall that driver. I have mulitple pcs so I can just switch puters if need to.
All I need is a little help getting the pc to recognize it or someone to tell me I am screwed till a developer makes a update to the utility.

I rooted my kindle fire 6.2.2 last nite with burritoroot3 (the latest version) and also installed twrp with kfu 0.9.1 (older version of kfu).
I had problems installing with kfu 0.9.3 (the latest), so I used kfu 0.9.1 and it was successfull
ill check it out thanks man
*b63 helped me through many a private message and got my kindle working again. He is the awesome. If you run into this problem, ask him or me. I will be more than happy to share what I learned.*
Good sirs and madame's,
I am a noob and a complete and total idiot.
Now that we have go that out of the way, I really could use some help. I am at the verge of tears.
I have tried rooting my kindle fire 6.2.2. using the burritoroot2.bin, the su, the com.noshufou.android.su-1.apk, rootcheck.apk, and the superuser.apk files. After several attempts, I was able to finally verify that my kindle was now rooted using rootcheck. Using fileexpert.apk, I installed the GoogleserviceFramework.apk then restarted my kindle. afterward, I tried making my system and app directories read/write then cut/paste the androidmarket.apk into the app directory. It kept saying attempt failed, though I did successfully root my device, was told that permissions were given to fileexpert.apk. I decided that maybe I needed to restart my device after setting the permissions to read/write. At this point my kindle has be continuously stuck in the startup/recovery loop.
I have attempted using the Kindle Fire Unbrick utility: http://forum.xda-developers.com/showthread.php?t=1428428 but every time it tries to do anything to the kindle, the last lines are
<idme> Invalid permission
reboot: operation not permitted
congratulation, your kindle should be unbricked!
Now naturally it is not. I have tried all of the options in the file. The recovery loop just stays stuck at "waiting on device", and I have tried turning it off and on with it connected and reconnecting it and it still doesn't do anything.
I have tried the kindle fire utility:
http://forum.xda-developers.com/showthread.php?t=1399889
but it didn't work (I am pretty sure it is for earlier versions anyway).
So I am at a loss. I have had this thing for 3 days. I followed all of the instructions to the best of my ability, and I have no friggin' clue as to how I bricked it, or how to fix it. I would be happy with a complete system restore, and just reinstall all of my stuff, as long as I could get it working again.
Please help.
would suggest that you try to follow this thread:
http://forum.xda-developers.com/showthread.php?t=1455501
there should be everything you need
I have an experience with one of my laptop, even after I follow all instructions from this site and others, I can not get my KF to root, then I switched to another laptop in the office, and now it works without any problem. I know it may be different with your problem, but it just may work if you switch to other computer
Well, it won't let me post in the relevant thread so I figured why not make my own. I got a brand new kindle (my old one malfunctioned, non-root related), and was attempting to root it. Mind you, my old kindle rooted fine. I went with the utility option, and it all seemed to work fine. However, upon noticing this:
Code:

I noticed that root was NOT in fact installed. Mind you, all through the Kindle Fire Utility (latest version). I thought to myself, alright, maybe the tool is bugged at the moment. I went ahead and did it the old fashion way....or not. Again, it would not root. So, while following instructions (all of which say to use a version of twrp which is not the current version) I just try again, to the letter. Never once do I encounter a "Yellow Triangle". Instead, now my kindle fire will show the "Kindle Fire" logo at boot, with a little android guy above it.
I did install super user, but without root, it's useless really.
I even factory reset, to try and start from scratch. This however did not remove what I assume is FireFireFire (The android icon over the Kindle Fire Logo) as the bootloader, so that's a problem in itself. What am I doing wrong? What can I do here? I'd love root like on my old kindle fire, I'd love to have Google Play/Market, and a real youtube app. However, none of the things on the forums are actually rooting my kindle. I've no idea where to go from here, and help would be greatly appreciated.
In short:
- Tried to root with Kindle Fire Utility (Latest Version)
- Success in running, but no root.
- Tried to root manually.
- Never got "Yellow Triangle", could boot twrp, no root.
- Tried to factory reset.
- Did not remove FireFireFire, still weird kindle fire boot up logo.
- Lost. Please halp.
I used the older version .0.9.3 I believe it was worked perfect just like it did the first time on 6.2.2
Wee update.
I searched around for the actual twrp they mention in the thread, found it, and got to the yellow triangle. Continuing my adventure of solving my own problems. Just loaded into the kindle fire, testing root. Will edit this post if success, and tell others what my problem was (for them, if they see the same problems).
Nope, still getting permission denied errors when installing the vending and what not. Still no root...At least I got the triangle though?

Well, it seems I have finally got it rooted.
Using the kindle fire utility to install vending and whatnot does not currently work on my device (made respect to the creator, it's just not working...).
I decided to try and download/install it manually, and I now have root. I'll see if the forums will let me send him a message.
As I said, I'd mention how I "fixed" (more like just trying everything) it. It was simple. I went and found the actual TWRP the guide mentioned.
For reference: twrp-fire-2.1.0 will NOT work (at least for me) to root the kindle. You require twrp-blaze-2.0.0RC0

For your information or anyone else's, the yellow triangle is the old FIREFIREFIRE, the bootloader. The new version has a android guy over the kindle logo. So now that you have the yellow triangle back, you're using the old Firefirefire.
To easily update FireFireFire, or TWRP, I recommend smirkis' scripts that run right through your kindle, no computer necessary (you must have root).

By the way twrp does not root your device its simply a custom touch recovery for the kindle download root checker or try an app that requires root like root explorer it will ask for superuser permissions when opened just check remember and allow to grant permission
I was able to root the KF in short order with the utility -just follow the instructions to the letter, make sure ADB is functioning correctly. If you are having trouble with ADB, just make sure that it says composite, and not straight android USB. If, when you go to device manager, and the driver isn't the composite variant, unplug the kindle from the computer, delete the driver entry from device manager, and then plug the kindle back in. If you've edited the correct driver files, it should pick it up and ID it as a composite device and you'll be on your way to root in a few minutes from that point.
Also - I didn't use TWRP, instead opting for CWM. No particular reason why, I'm just familiar and comfortable with CWM and I know from experience that it "just works".
