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...

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...

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.
Love life.

Bricked and will not reboot!

This is my gf's kindle fire and she wanted it rooted to have the google play store. This is completely untouched Kindle and on windows 7 pc. So I downloaded the KFU latest release 0.9.6 and proceeded w/ option 2 to install permanent root. Let it sit for about an hour with the please wait and waiting for device messages at the bottom of the screen. I wasnt sure how much longer this would be so i just let it sit. Couple minutes later my gf comes and let me know that she unplugged it accidentally while vacuuming. Im now stuck on the TWRP screen and will not reboot at all. If it try to reboot i get a message saying " E: System in not installed - preventing reboot! " which makes me think that the OS got wiped somehow. All I can do is let it run out of battery. Now in the KFU abd status: Offline and boot status: Unknown. Although that Windows will recognize the device as its showing up in device manager under Adroid Phone: Android ADB interface. What can I do?

not showing up.

Letting your battery run out would be one of the worst things you can do. I don't know where people get the idea that running the battery out of a device is a miracle cure, but it's ridiculous.
First, use the "Mount" function that comes with TWRP and mount your sdcard. Choose a ROM and transfer it to your sdcard to be flashed in TWRP. Once you have a ROM installed, select Reboot > Reboot System.
If you want the stock based software, install MoDaCo. No need to root or install Google Play Store.

Mount function not working either. I hit the button and never shows up on my comp as a storage device.

Yep, that's a problem. In order to fix it, you'll need the command line. To use the command line, you can either fix the Windows driver problem that is causing the "adb offline" error, which could be a very painful process, or set up a LiveUSB to run Linux (recommended).

Could I just remove and reinstall the driver? Weird thing is that its still showing up on the device manager Adroid ADB interface.

In a perfect world, yes, that would work every single time.

Well i managed to get the driver working and got to flash the latest update from amazon on and renamed it update.zip to get it to flash. Now it seems like its in a bootloop just showing kindle fire in the orange letters. Connecting it to KFU it shows ADB status: online , but still showing bootstatus as unknown.

You need to fix your drivers again.

Now i cant get into anything other than the kindle fire screen. I just made a Factory cable but not sure as to what that is supposed to do as i dont notice anything different when i plug it in other than it powers up by itself instead of having to press the power button. I cant get into twrp anymore. Trying a few other things i keep getting a - exec '/system/bin/sh' failed: No such file or directory (2) error message.

You're in fastboot so adb commands won't work. You can only use fastboot commands in fastboot mode. As for installing TWRP, go to the TWRP website and download the actual TWRP.img file. The file that comes with KFU is nothing more than a broken link (2kb I think?) and it doesn't work. Put the file you downloaded into your KFU folder and rename it twrp.img, just to make things easier. Then "Shift" + "right-click" on the folder containing the newly downloaded twrp.img and select "Open command window here". In the window that opens up enter the following commands:
fastboot -i 0x1949 flash recovery twrp.img
fastboot -i 0x1949 oem idme bootmode 5001
then hold the power button until the device shuts off and start it up again. It will then boot into recovery.

Awesome thanks for the help Soupmangnet!! I got it in twrp recovery now. I would like to just have it back to stock at this point and have the latest update downloaded from amazon on the sd card. Im just worried that this will put me back into the same problem as before. Do need to download or fix something else?

Make sure you change the file's extension to .zip as before, and above all else, wipe System and "Factory Reset". Everything should go well for you.

You sir are awesome! Everything works great! Now to get play store.

You could have simply just flashed modaco instead of going through all he hassle of flashing update.zip and wiping out fff and twrp...

[Q] Bricked KF2 - no OS, fastboot & TWRP available

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.

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.

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?

[Q] DUH, rooted otter2 but forgot to copy ROM and GApps first

Ok so I screwed up.
But I should say I'm not a complete newbie at rooting KF and KF2s. I've successfully rooted and put custom ROMs on a number of these devices before. Yes KF2s are harder to root and customize than KFs, I understand that.
Here's what I did.
Checked stock Kindle OS version (10.4.x). Turned on ADB etc before starting.
Rooted as per this page: http://forum.xda-developers.com/showthread.php?t=2075959
Booted up into Kindle OS.
Connected to PC, ran elevated CMD.
adb push stack /data/local/tmp/
adb shell su -c "dd if=/data/local/tmp/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1"
adb shell su -c "reboot bootloader" (with fastboot cable attached)
fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin (to install more hack-friendly bootloader)
fastboot -i 0x1949 flash boot otter2-freedom-boot.img
fastboot -i 0x1949 flash recovery otter2-twrp-2.4.4.0-recovery.img
fastboot -i 0x1949 reboot
Ok so here is where I am at. I can boot to TWRP, no problem. I just have no ROM and GApps to flash.
If I do adb devices, it does not give me an error, but lists no devices, I just get 'List of devices attached' with no list of devices.
If I try:
adb push cm-10.1.3-otter2.zip /sdcard/
I get
error: device not found
despite the Android ADB Device being listed correctly in device mangler, and apparently working properly.
I tried to mount the data partition in TWRP, and tried
adb shell mount /sdcard
but still no joy.
So anyone any idea how I can copy the ROM and GApps to the sdcard partition on the KF2 using adb or some other way.
The device won't boot and recovery to factory defaults doesn't work either, I get the boot loop to the red triangle that others have.

I'm confused I thought you said it would go into twrp recovery but the red triangle is stock recovery, if its stock recovery there is no adb, you will need a fastboot cable. If you are getting twrp then try uninstalling the adb device and reinstalling it with the drivers in my signature.

I can get into TWRP without an issue. If I let the device try and boot the Kindle OS it reboots a couple of times then I get the triangle saying it can't boot.
I guess I can try reinstalling the drivers.
Thanks.

When you can get in to TWRP you can use "adb sideload" or "adb push" to transer your data over to your kindle.

No, I can't.

Your drivers worked, thanks!
Although I am not sure why the previous driver I had installed didn't work, since I've had KF2s hooked up to this same computer before.
In any case, I booted up the device to TWRP, plugged it in, installed the driver, and used adb push to copy the ROM and GApps over.
Thanks again.

[Q] TWRP flash failed but firefirefire installed, now I can't get to fastboot mode

I've been trying to root my Kindle Fire running 6.3.3. I bought a fastboot cable and got it to boot into fastboot mode to flash TWRP and firefirefire. I ran the commands and TWRP failed but firefirefire installed. Now when the kindle boots I get the firefirefire bootloader but it cant boot into the recovery because the TWRP never installed. Also, I can't get it to fastboot anymore, not even with the cable. Can anyone please help me get TWRP installed? I've read many forums and tried about everything I found.

FFF bootloader supports fastboot commands, but the flash command is now
fastboot flash recovery file name
ie drop the -i 0x1949
Code:
fastboot flash recovery openrecovery-twrp-2.6.3.1-otter.img
because the fastboot mode window is short
with kindle connected to pc, power off kindle, enter commands, then power on kindle

I've been trying this for about 30 minutes or so with no luck...I even downloaded a different version of the twrp image. Do I have to wait for the fastboot screen to start the command or do I start the process before powering on the device? I'm not really sure what I'm doing wrong here.

Should be able to do it either way but I press enter, before the power button
This will not work if drivers are not correct
could try
Code:
fastboot devices
as a test should get something like
Code:
123456789 bootloader
back in command prompt

I finally got it to work and I can't thank you enough. You were right. I knew my computer recognized the device with adb in normal boot but my computer wouldn't recognize the device in fastboot mode until i reinstalled the android driver while it was in fastboot mode. Now I have a custom ROM running Google Play apps! Again, thank you!

Hey, I don't know if this will help others, but I had a hell of a time trying to get my kindle to recognize while in the bootloader/fastboot mode... It frustrated me so much that I had to write about it.
I recently switched to Windows 10, so it seems like my computer is relearning drivers and stuff...
My kindle was fine when on, and I could issue adb commands from the main screen, but when in fastboot mode, I couldn't get it detected. I knew the drivers were an issue, but I couldn't figure out how to do it. I looked at Amazon's support pages, went through the SDK route, tinkered with the adb.ini and so forth... to no avail.
Post after post said that the easiest way to install the drivers was through the Kindle Fire Utility, but for some reason, the drivers in the .bat file kept failing and would not load. It took a good few hours to figure out the solution.
When I asked the Web why the drivers kept failing, I came across a post that said Windows was actually blocking unknown drivers from loading onto my system. I really wish Windows had told me that instead of just saying "Fail"...
I had to hold down the shift button and click restart on the start menu, and when the computer restarted, I when through: troubleshoot -> advanced options -> startup settings and clicked on Restart. It eventually gave me the option to disable that signature verification [F7]
My explanation is crude, because I want you to look it up properly. Just search for "disable driver signature enforcement" and you should be fine.
Hope this helps others out. I may have to revisit my own post just to see how to do this again.
