[Q] Kindle Fire v7 cant Root :(

I have tried to root my kindle with the Kindle Fire v7 and have had no luck, It comes back with The system cannot find the path specified, I have installed the drivers and my kindle shows up as Android Composite ADB Interface. Thanks for any help in advance. I have also tried the burritoRoot with no luck. I am on version 6.2.1 I have never had problems with any android devises before but this seems alittle different.

i have the exact same problem. would really appreciate some help

I had this problem and here are the steps I took to fix it.
Go to Google's website and manually download and install the SDK, at the end when it asks you to open the utility to download images and such, uncheck the box and click finish.
Download the Kindle Fire Utility v.7
Connect your Kindle Fire to your usb port.
Go to Start Menu -> Accessories -> Run and type in "devmgmt.msc" (without quotations)
There should be an "unknown device" with the name of Kindle Fire (or close to it), right click that and click update driver software.
Click "Browse my computer for driver software"
Hit Browse and locate the "drivers" folder in the Kindle Fire Utility folder
Click next and let it install the software
Go into the Kindle Fire Utility folder and run "run.bat"
Everything should work as expected from here on out, or at least it did for me

I think for both us we already have the drivers installed. the problem is in running the actual bat for the utility. unless maybe we did something wrong in installing the drivers, but i don't think so. I actually used the exact same method to install the drivers as you did.

Check your system path for what the program is trying to run. If the path is there, make sure the file its calling is there. Google adding a path to windows for more info.

I think he problem has to do with the program not finding the kindle

try this it may work:
open a cmd windows from your sdk tools folder, not the platform-tools, just tools and run this:
android update adb
then go to your user folder c:\users\username there should be a folder named .android in there, open adb_usb.ini and add this line at the bottom

save close and update driver again, hope it works
credit goes to iluretar btw. make sure that you have the android sdk before doing this. delete whatever driver you had before this. after doing this, install the drivers manually through device manager and browsing to the folder included with the utility. and then...it works...for me at least, not sure why. oh, and...er...not sure where you find the link to android sdk, but i'm sure someone can provide you with that...

Well I guess im still not doing it right cause im still getting The devise not found.

I moved my install_drivers.bat file from the drivers folder to the same folder as run.bat and ran it (install_drivers.bat that is). It seemed to install correctly. Now, however, my kindle will not mount. So when I try to use the utility to install TWRP, it stops at "Installing TWRP... If we get stuck here for a while, power the kindle on and off a few times. < waiting for device >"
I have rebooted my device 6 times and it still does not work. My device no longer mounts, I can't even see it in device manager. I tried installing the drivers manually prior to moving install_drivers.bat. This seemed to work but I ran the install_drivers.bat after moving it anyway, maybe that makes me a noob.
Anyway, is there a way to fix this? I want root on my device!
EDIT: Here is the script I am getting in cmd when I run install_drivers.bat. I realize that the problem is I am running Windows 7 x86. But is there a way to run it for x86 instead of x64?
This tool will attempt to install the correct Drivers for the Kindle Fire.
It will also perform the setup required for adb_usb.ini in .android for you.
This version of C:\Users\Chris\Desktop\Kindle Fire Utility\tools\x64\devcon.exe
is not compatible with the version of Windows you're running. Check your compute

Here is what i did. First off, not just any data cable works, i found that lg cable dont like adb. Some samsung cables give me trouble too. But anyways. Click start menu, type device, click and open device manager the go back to start type device again and open device and printers. If the kindle has installed its drivers then you should see "kindle" in DEVICE AND PRINTERS click on kindle go to properties select driver "tab" and hit uninstall. Open device manager and make sure its still sees the kindle as ADB interface. If so then you should be all set. This should be done after editing the adb_usb file and updating the google drivers.

Thank you, this is what finally got it working for me. I had tried everything; installed 3 different USB drivers, edited files, moved files around, all with no signs of progress. Finally this approach made everything work perfectly!

Kindle fire not seen

Ok so I am new hear and I was reading in THIS POST about installing TWRP using the Kindle Fire Utility. So I installed the drivers as directed and I see in my device manager "android ADB device" and in my taskbar I can eject the kindle. In File Manager I do not see the Kindle fire and the Kindle Fire Utility is not seeing my Kindle Fire. I am stuck and cannot post in the above forum because I have not made enough posts. Any help would be greatly appreciated. I would like to install Cynogen Mod to my Kindle fire to be able to access the full capabilities of this wonderful device.
Thank you

a good method to start is using kfu as you suggested but there are some tricks to get it running:
- place it to c:\ and rename it to "kfu" (it don't like spaces in pathname)
- try to install the correct drivers by running install_drivers.bat else install/update them manually:
http://forum.xda-developers.com/showpost.php?p=21720811&postcount=41
- pay attention on the driver verification level:
http://forum.xda-developers.com/showpost.php?p=22065426&postcount=846
- the drivers are in c:\kfu\drivers\kindle
- right drivers for each mode:
normal & recovery boot -> android composite adb interface
fastboot -> android adb interface
once you got rid of the drivers you have to update the run.bat of kfu to work with burritoroot3:
http://forum.xda-developers.com/showpost.php?p=21749205&postcount=792
now you should be good to go ...

Thank you BB3 I will give this a try later tonight. appreciate the help

man install buritoroot and TWRP(which installs and FireFireFire) by yourself when i tried with the kindle fire utility all got were errors, but when i installed it by myself everythink went smooth. Just find separate guide for every step
1.Root
2.TWRP and FireFireFire
3.CM7

I'm having the same problem as you and it sucks I just want to root it

Hate to necro post, but I'm having the same issue and none of the posted suggestions work. I have the ADB drivers installed (the Kindle is detected as "Android Composite ADB Interface"), but I did not install the drivers using the KFU batch file; I could never get it to stop producing the unsigned error, no matter what system settings I chose for unsigned drivers. I ended up doing a manual driver install and directing the installer at the driver files that came with KFU. Now KFU refuses to "see" the Kindle connected to my system and therefore I can't do a thing with it. I am able to browse the Kindle files in Windows Explorer (should I be able to? I've seen conflicting answers to this), but KFU always reports its ADB status as "Offline". Soft disconnecting the Kindle (hitting the "Disconnect" button on the Kindle) doesn't change anything, except removes my ability to browse the Knidle files (no surprise there).
This is a fully updated (6.3) Kindle and Windows XP. I did attempt to manually do what KFU does automagically prior to finding out about KFU, but that effort produced similar results; the Kindle was never detected by the SDK tools, despite the drivers loading properly. I have also tried multiple USB ports on my system, but they all produced the same results. About the only thing I haven't tried is a different USB cable, but if the Kindle is able to be "seen" by the OS correctly, I don't think the cable is a problem.

Have you tryed rebooting your computer? http://liliputing.com/2012/03/root-...ogle-play-store-with-kindle-fire-utility.html or http://m.youtube.com/#/watch?desktop_uri=/watch?v=mwMHIkX20YI&v=mwMHIkX20YI&gl=US nat3mil gives good instruction it helps to watch the video do the step while paused then move onto the next its how I did it the first time the second time I just used the utility was easy peasy cause drivers were already installed and functional

Yeah, I followed those exact instructions and video, with no results. Reboot doesn't make any difference, KFU still can't see the device.

If you followed the instructions to the t like not plugging in your device until you have the drivers installed .then you may have something on your computer preventing adb try the 6.2.2 method
http://m.youtube.com/#/watch?desktop_uri=/watch?v=AZ88CYWv0FU&v=AZ88CYWv0FU&gl=US or just keep looking for something that works cause people miss steps all the time sometimes its persistence or trial and error that gets results I'm very surprised your not seeing anything in device manager that applies to your kindle mine installed some drivers immediately when I connected it I had to change them to root it but it did show up in the list of devices as well as appearing next to my c drive as a kindle for SD card access but I'm on windows seven anything I connect does something.

No, Device Manager sees everything fine, it's KFU that refuses to see it. I am getting both a Kindle storage device and an Android ADB device in Device Manager, as well as seeing the Kindle as a removable drive in Windows Explorer. The old 6.2.2 instructions are of no help, that's what I tried the first time I attempted to root the device before the 6.3 update and I got the same exact results. I don't know what on my machine could possibly be interfering, this is a very barebones XP, I don't even run anti-virus on it.

Could be your machine but don't use the utility and when you do put twrp on if ya get there use 2.0 the older version people are having trouble with the new one http://www.techtuple.com/477/how-to-root-kindle-fire-6-3-easily/ this is done through cmd without utility. Original thread here http://forum.xda-developers.com/showthread.php?t=1568340
About all the advice I can give you all else fails use another computer windows 7 machine things are more straight forward than xp
Edit: just a side note a lot of people are bricking their devices I keep remembering the Christmas story be careful you'll shoot your eye out also some people I believe are having success opening kfu attaching thier fire while off then powering up the kindle

I read somewhere that the utility doesn't work for xp wish I could find the post I think you need to push the files the old way using command prompt and you will get it sounds like your drivers are there but utility is useless

If your device isn't recognized it is a driver issue, regardless of whether your computer says they are installed or not.
Scrap your current drivers and start fresh using the tutorial posted here:
http://www.jayceooi.com/2011/12/13/how-to-install-kindle-fire-adb-usb-driver/
Forget about KFU, get Android SDK and set up the drivers yourself. Learn to use fastboot to manually change your bootmode manually through command prompt. It will save you hours of heartache in the future.
Reinstall your (non KFU) drivers and try again.

Thanx soup better said than what I was trying

if you want to test to see if your drivers and adb are correctly installed plug your kindle in to your computer type cd c:\kindleadb then hit enter then type adb devices hit enter mine said adb server out of date. killing...
*dameon started successfully*
list of devices attached

c:\KindleADB>
this is all in command prompt at this point I could paste in commands and root my kindle run this test to verify drivers are correctly installed if you dont see this try again on driver installation.

First time i've ever rooted a kindle and i had the same problem.
To fix this just go to device manager and uninstall the driver and then unplug and replug in your kindle then run the utility.

oh no trouble at all rooting rooted rommed and rockin here took the 6.3 ota this morning with 5 mins I was rooted with fff twrp then went back to 1 of my restore points of cm7 after a backup of 6.3 thanx tho

This will only work if the device is booted to a point where it will receive adb commands. Otherwise, use "fastboot devices". Sometimes if you are stuck at the bootloader it helps to shut your device down completely and restart before issuing fastboot commands.
Beyond that, it's a driver issue.

I had that same problem., but then I uninstalled the current drivers for my kindle altogether, and disabled them, then I ran install_drivers .bat again, then it worked.

Help: Problem getting drivers to install.

I've been trying to root this thing for about 3 hours now. I'm on Windows XP and I can't get my kindle to be recognized in adb. I've tried updating my drivers in SDK and still no dice. All the guides appear to be for windows 7. Nothing I do is working. I've rooted several devices including tablets in the past but this one is almost impossible. All I want is the android market on my kindle.

Uhm... I'm not so sure about windows XP when it comes to automatically searching for drivers, but turning on the USB debugging setting might get windows to download everything necessary for adb to recognize the device. It worked on my phone, when I couldn't find the drivers... Just turned on USB debugging under "developer options," and windows got to work right away. Rooted it no problem.

using xp is the best choice - you dont have to care about 32/64bit and the uac (user access control)
hope this helps you to get rid of the drivers:

as described in the linked post it's a good practice to move and rename kfu to c:\ that it is c:\kfu - it don't like spaces in pathname
the error message looks stange because "and" is no command - would try to redownload it
if it says "findstr" is not recognized as command then check your path varible - it should include c:\windows\system32
furthermore i use to run the batch files from the command prompt - cd to c:\kfu and type install_drivers.bat - the same with run.bat

It took three computers but I finally rooted the kindle.

realy not shure about the blank line(4) - never seen it so
you can try also to stop the adb server with "adb kill-server" and then check with "adb devices" again
wait - just saw that in device manager it says "samsung android phone" - this should be only "android phone" - maybe reinstall the drivers ?

OK, I was forced re-format hard drive and re-installed brand fresh Win7 Professional 64bit. Everything got worked this time. I understood, I think my Win7 was somehow corrupted in device drivers conflicts.
Thank you all! Now, I am going root my new Kindle fire.

I think I soft bricked the KFHD 7', help pls.

So I was following pesano's KFHD tweak thread and found out that my int.d was probably not working, so I decided to re-do the process. I wasn't thinking straight and deleted the install-recovery.sh (this is the only one that has an original file) without copying over the new file, and rebooted. Now my kindle is bricked, I think, I can see the kindle fire logo and then the screen goes blank (still has power). When I plugged it in PC, it can be detected as Kindle, but the driver is not taking effect (yellow exclaimation in device manager), and could not connect as usb device either. Is there any easy way to get it back without fastreboot cable?
Thanks a lot.

No.. and really you shouldn't be doing these things without a fastboot cable.. What do you mean by the driver does not take effect? It sounds like you need to fix the bootloader. I would head over to the Kindle Fire First Aide thread and talk to Chris and see if he can help you out. Is adb working or have you checked? If adb is working then you will be able to enter fastboot without the cable..

I meant I had the drivers installed before but now the device is not using them although it was showing up in Windows 7 device manager as "Kindle". The adb is not working, showing "device not found".

I hardly remember if I used adb commands for rooting this device. I followed the guide here, which runs a series of bat files.
I tried re-installing the kindle drivers (without deleting them first, so it's an overwriting process), and then reboot the PC. Still the same symptoms: "kindle" was listed in device manager of windows 7 but with the yellow exclaimation mark, tried "update driver" pointing to the kindle driver folder but was told that system could not find/install driver in that location.

You have to update it manually. Do not let the computer find it, you have to find it where you downloaded it too.

Yes I was referring to manually point to the folder I downloaded the kindle fire usb driver when "updating the driver" in device manager. The automatic search driver never worked. But still, even if I pinpointed the directory where the driver sits, windows still told me could not install the driver.
And btw, the guide you linked to is for Kindle Fire, not kindle fire hd,, does it matter then? Thx.

A lot of it is the same I am sure some aspects of the GUIDE do not work but as far as installing ADB drivers it is good. Did you uninstall it and also hit delete all software with driver?

did u recover

Hey. I am having a terrible time getting my KFHD 7 back to stock. I used KFFirstAide to root it and when I went to restore it back to factory settings it ended up with the holo launcher lock screen and the android start screen. Has no notifier bar at top or menu bar at bottom. Lock screen let's me go online, to the camera, or just unlock. Don't know what happened! It's not recognized in ADB but shows up on computer as Kindle. I just want it back to stock so I can use it again! PLEASE HELP!!

In my situation, when trying to update the "Kindle" driver from Windows device manager, use the option to let you choose install driver from a list of devices instead of pointing to the directory where you have the adb driver (it will always tell you can't install even if u point it to the right directory).
In my case, I had all the drivers installed already, so when I use the option to install from the list of known devices, I can choose so"Android adb" or sth similar in that list. And after that you will be able to restore the adb connection.

the the reason your kindle cannot communicate properly with your computer is because it is soft-bricked, only way to recover from a soft-brick is with the use of a fastboot cable, if you are partially soft bricked...ie boot is intact and functional but system filesystem is corrupt you may be able to access fastboot with the use of a fastboot command

Like I tell everyone, go here to solve your problem.
