I have just bought Kindle. So i try to root and install TWRP recovery for my Kindle. After installing TWRP, because don't look Super User icon in Kindle; I took hard-reset my device in Settings. And Now My Kindle boot Logo Kinder Fire stuck on here.
What problem ???? Please help me....... i don't know i had just done nothing. Thanks guys !
I try to text in command dos: "add shell" but it show may Laptop Screen:
- exec '/system/bin/sh' failed: No such file or directory (2) -

it sounds like you are stuck in fastboot.
when you plug in your kindle, does device manager see it? if so, can you tell me what it recognizes it as?

I'm having this same problem. It's apparently stuck in fastboot. I can't even figure out how to type in adb commands or fastboot commands (meaning I could before and now when I tried it says command not found, but I didn't change anything. It won't recognize my device and when I try installing the android-winusb.inf it says it won't let me. I don't know what else to do. Any help would be appreciated. My Kindle is listed as unspecified device.

when I plug in my Kindle, KFU Show:
- ADB: Online
- Boot Status: Unknow
Now I try to install CMW recovery or TWRP, but I can't do this . All show: - exec '/system/bin/sh' failed: No such file or directory (2) -

Had this issue last night when I tried to TWRP my friends Kindle Fire. Plugged it in and typed:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot

turn off kindle then try running the command before pluging in kindle to usb then plug in kindle and press power button once.
edit: if that doesn't work try installing kindle fire unbrick utility its very simple to use and normally sorts most bootloops etc.

thanks guy much. But i tried all, i used KFU to try installing Recovery ( CMW, or TWRP), try to plug in USB Kinlde, press power button, etc. But It'S seem not working, all show: " exec- system/bin/sh failed ; not such file orr folder "
i also use tool KF Unbrick on XDA, but it's too. Reply show: " -exec- "system/bin/sh"...
Can U know that what problem in "system/bin/sh" of Kindle Fire ???????

if you get this error message to the command "adb shell" then the system shell is messed up
sorry - but you'r only way to recover is a factory cable

You are only soft bricked. When I asked what happens when u plugged it in, I mean in device manager not in the kfu. Device manager needs to ee the the kindle as adb composite device. If it does not, then you need to get the right driver.
You are stuck in fastboot. You simply need to issue the right reboot code and you will be fine

he is absolutely right, this happened to me and nothing would work until I got a factory cable

This is a typical problem with KFU.
You need to go to your device manager and uninstall both the adb and android drivers then reinstall them manually. Sometimes it helps to restart your computer and Kindle afterwards. Make sure your device manager says both "Android Phone" and "Android ADB Interface" NOT "Other Device" and "Kindle".
When you are stuck at the boot screen it means you are in fastboot mode. In fastboot mode your device will only recognize fastboot commands. If your device doesn't recognize fastboot commands (KFU uses fastboot commands to change boot modes), 99 times out of 100, it's a driver issue.
A factory programming cable, while nice to have, is not usually necessary. A factory programming cable does two things. It provides power directly to the device instead of the battery AND forces the device into fastboot mode (stuck at boot logo). Since most of you with this problem are ALREADY in fastboot mode, a factory cable would be pointless.
Make sure you are 100% certain that you have the correct drivers installed and configured properly and then use the command prompt to change your bootmode to 4000.
In command prompt, navigate to the folder that contains fastboot.exe and enter the following commands...
fastboot -i 0x1949 oem idme bootmode 4000
fastboot reboot
(or hold power button for 30 seconds)

i have the same problem as you it fills good to not be the only one

Stuck at KindleFire white/orange logo. Unresponsive to ADB commands.

First off, thanks to everyone on here who's posted numerous help guides that have helped me in the past. I've rooted several phones in the past and figuered I'd try to root and install Jelly Bean on a Kindle Fire I won at a work event (woohoo!).
The problem right now is the kindle is stuck in fastboot (no root, twrp installed) it boot into the non-animated white and orange "kindle fire" logo screen and stays there.
What I did to put it there:
On a Windows 7 machine, I used KFU 0.96. After reading instructions, I installed TWRP.
Since then, it is not repsonding to adb commands. It will mount the drive to the computer, and the drivers show it's using the correct one from Google Composite device.
After researching, I found someone who mentioned that after several restarts, and smashing "normal boot" commands thru adb while the kindle was starting up (and before it went unresponsive) he was able to move along. When I did this (with KFU), Kindle went into TWRP. From there I followed instructions on flashing pre-rooted 6.2.2 (as the guide indicated, doing wipes) but the flash always failed.
Assuming something wasn't working with Windows, I've gone home to my macbook running Ubuntu 12.04, and while installing SDK from Google, I can not figure out how to get the google sdk running. I followed this guide http://forum.xda-developers.com/showthread.php?t=1550414 but I can't get to step 5, I cannot get the Android SDK Manager to run!!
I have access to dozens of Windows computers, I'm fine with going back to them, but everything I've read makes me think I've got a better shot with Linux due to driver problems on windows.
Also, when I had TWRP loaded on the Kindle, and connected it to KFU 0.96 it said my boot mode was 0x5003.
fastboot commands will not execute. I'm sending them like this:
(Devices list)
[email protected]:~/Android/KR$ ./adb-linux devices
List of devices attached
???????????? no permissions
fastboot:
[email protected]:~/Android/KR$ fastboot getvar product
fastboot: command not found
Someone had a similar problem here- http://forum.xda-developers.com/showthread.php?t=1765546 but I want to see if I should follow that thread or try something else instead, before I go making more changes.
Thanks for reading! Will gladly send pizza to someone who can help

I'm not an expert at fastboot and adb stuff but I can try to help.
As far as I know, the Kindle needs to be in fastboot mode for you to be able to use fastboot commands. The boot mode has to be 4002.
Are you still able to connect to your Kindle using KFU?

yes. but it also spits out "-exec '/system/bin/sh' failed: No such file or directory (2) -" when I send the command to reboot into fastboot 4002, the kindle then reboots, and has the white and orange "kindle fire" logo.
also: C:\KFU\tools>fastboot devices
returns blank, goes back to prompt. so I try
C:\KFU\tools>fastboot devices
< waiting for devices >
and does nothing
Where to now?

Try uninstalling and reinstalling the drivers. If your in fastboot mode, adb wont work. After reinstalling the drivers, type:
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
If the drivers installed correctly, these commands should work and get you out of fastboot(which it seems your stuck in)

"-exec '/system/bin/sh' failed: No such file or directory (2) -" means your system software is broken, so it probably won't boot. In addition, either the "sh" binary doesn't exist there or the KF is not mounting the system partition to let you execute "sh" to run "adb shell" commands. To clarify, you need "/system/bin/sh" to run any "adb shell" commands. Because you don't have access to it, you cannot change the bootmode this way. There is no "command to reboot into fastboot 4002"... you have to set the bootmode to fastboot (4002) and reboot it. Because you cannot run "adb shell" commands, you cannot change the bootmode. Your next reboot just boots into whatever the bootmode happened to be at the time you tried (but failed) to change the bootmode. All of this is spelled out here...
http://forum.xda-developers.com/showthread.php?t=1668159
It's very likely that you'll have to get a factory cable to force the device into fastboot mode... that is unless you want to open the back cover up and tinker with the motherboard.
Also, you have permission problems when you try to run adb. You either have to run adb as root, or use this guide...

and set things up so a regular user won't need root privileges to access the USB ports.

for real, I probably would have paid $50-60 too, it should be an easy fix with a factory cable. (which I already have one of after I bricked my kindle once)
Also, as a side note - Amazon will replace it for $100 "not under warranty" because you bricked it through the tinkering process.

Actually, it turned out better than I could have planned. I told the company whom gifted to me t did not work, they sent a bike ,messenger to exchange it for me! Naturally the first thing I did with the new one was fire up kfu .96 and it worked perfectly this time. Stoked on this hashtaag jelly bean ROM. Hate the keyboard tho. And Google cards are fc'ng.

[ISSUE] Kindlefire bootloop

I was trying to root my kindle today and decided to use the kfu.
I installed the drivers etc and started the kfu
http ://i.imgur.com/qNQgD.png
This is what the screen looked like, so i pressed 1
and then i pressed 2
http ://i.imgur.com/aAHRM.png
and the window said sending something and the kindle rebooted.
but now its stuck at the kindlefire logo screen. and anything you do in the kfu says it cant find the device.
i tried to use the firekit hoping it would fix the issue with the normal_boot script but all it does is hang at "waiting for device"
I know i probably did something really stupid, but if anyone could help me fix this i would be very grateful.

i tried :
Getting out of fastboot mode
To get out of fastboot mode, make sure the bootmode is set to something other than 4002 and reboot the device. The examples below will set the bootmode to normal and reboot the device.
With the stock bootloader...
Code:
fastboot -i 0x1949 oem idme bootmode 4000
fastboot -i 0x1949 reboot
but adb and fastboot don't recognize that a device is plugged in, in device manager it shows as Android Phone, Android ADB Interface
Hardware ids show
USB\VID_1949&PID_0006&REV_0100
USB\VID_1949&PID_0006
i have no firefirefire, or twrp and am on unrooted stock 6.3 if that helps.

Disconnect the KF from the computer
Make sure the KF is off by pressing and holding the power button for around 20 seconds
Issue the first fastboot command and it will indicate that it's <waiting for device>
Connect the KF to the computer and it will turn on automatically
The first fastboot command should get sent to the device as it goes into fastboot mode
Issue the second fastboot command to reboot

The fastboot executable you are using does not recognize the "-i" switch... notice it's not listed under options.
Download KFU and use the fastboot in that distribution.

What were you doing when it got stuck at the bootlogo? Have you tried some fastboot commands to see how it responds?
Even if it's not in fastboot mode, see if you can get it there...
http://forum.xda-developers.com/showthread.php?t=1668159
If you can get it into fastboot mode and issue fastboot commands to it, you can change bootmodes, flash a recovery, or whatever else to get the device booting again. There's also a part in the above post to figure out what hardware ID is getting sent to Windows. That will be important in determining what your KF is doing.

[Q] KFHD Boot Logo Problem

Firstly, if there is already a thread about this that I've missed, I'd be appreciative if you'd send me in the right direction to get information.
Anyway, my Kindle Fire HD, rooted CM 10.1, will no longer boot past the orange Kindle Fire Splash screen. I've tried using fastboot commands and all of the button configurations in any and all attempts to get a response from my device, but it remains on that screen with no looping or any kind of change. When plugged in (or turned on while plugged in) it's registered in Device Manager as the usual "Jem-PVT-Prod-04" when drivers aren't installed, and then disappears from the Manager within five seconds. I can't install the ADB drivers because it vanishes, so I cannot communicate with the device from my computer; therefore I cannot fastboot (as far as I can see) and have no possible way to recover it.
Is my last hope a fastboot cable, or is there something that I have missed this whole time? Thanks for any and all help!

Thats a kindle fire hd 8.9" model, fastboot cables don't work on them. A easy way to fix this is to boot a ubuntu live cd and install the fastboot command from the repos and run it. Latest ubuntu is 14.04 lts and i haven't checked the package names yet, but if it has the same name as on 13.10 then these instructions should work. Boot a ubuntu live usb/cd and open the settings and look for something like software updates and check off all the download form internet boxes. Hit reload if it asks, and if it asks ignore the first command in the next part of the instructions.
Now open a terminal and run these commands:
Code:
sudo apt-get update
sudo apt-get install android-tools-fastboot
fastboot -i 0x1949 getvar product
Now that it says waiting for device, plug the kindle in while its off and you should be in fastboot mode. From there you can reflash it from windows with kffa or srt, or just do it manually while in ubuntu.

So I used the Linux command to put my Kindle in fastboot mode, but now it says it cannot connect with MTP device, so I still cannot flash any type of recovery. Even though it is in fastboot mode, and the drivers are installed, ADB is still not working on Windows.... and I'm not sure how to do it manually on Linux...

MTP is irrelevant with fastboot, as is adb, you don't use adb commands with fastboot, you use fastboot commands. You can use kffa or SRT to restore it from windows once it is in fastboot, or restore it manually in Linux using SRT's images. You probably will have to use SRT, I have heard a report that kffa's downloads for the images are offline again, though I'm not positive on that.
