[Q] Rooted Kindle Fire stopped working - Please Help

Has anyone else experienced this problem:
I rooted my Kindle Fire using KFU 0.9.5. it came stock with kindle 6.3 software. The rooting process was a cinch, and I installed GO Launcher EX and the Google Play store and many other applications that work great. I haven't installed anything in the past few days. It's been working fine since I rooted about 3 weeks ago. Now, all of a sudden, I go to open my fire and there's an android guy with an "!" Icon. I reboot. Get the yellow splash screen, and it goes to rebooting options. I select normal reboot. Goes to yellow screen, Goes to Kindle fire splash screen, goes to lock screen. I unlock with my PW and the device immediately turns off. So I try again, this time using recovery. Same scenario. Third time I chose fastboot. Now it sticks on the yellow triangle screen and does nothing. How do I get it to boot up? Please help.
Thank you,
Kyle.

There was a new update from Amazon causing problems. You can flash a different rom or get the new update from the Amazon website and flash it, which will make everything 100% stock again without root.

Ok. I got it to boot into recovery mode. when I go to reboot system now, it goes to the yellow triangle splash, then kindle fire splash (orange fire lettering, not blue), then it brightens up, and goes to the lock screen. then immediately powers off. reboots into the yellow triangle splash, then an android robot with a loading bar that fills about 25%, to a mini android robot with an orange ! triangle.
If I have to flash a new ROM, which would you suggest?
Thank you,
Kyle.

Also, in the CWM recovery, there's a factory data reset. Will that undo the root? Or will it just wipe the memory?

???
Please advise. Currently my Kindle is stuck and I'd like to have it operational again. Even if that means re-rooting it. Does CWM Factory Reset wipe the root or just delete the memory on the device. Is that even the correct route to go? Is there an easier way to get out of this boot loop? KFU won't recognize the device because it won't power up all the way.
Thank you.

Factory reset will only wipe your user data.
To break root and restore to factory original you have to flash the latest update from Amazon.
Google "Kindle Fire software update", it will be on the Amazon website.
Change the file extension from ".bin" to ".zip" and put it on your sdcard.
Flash the new update.zip in CWM

Ok, but I still cannot add anything to my device because it will not start up in any mode, so my computer isn't recognizing the device. How do I get the computer to see the Kindle while it's "off"
I've read http://forum.xda-developers.com/showthread.php?t=1552547 and it's not very helpful in that regard.

Can you boot into recovery? If you can, you're halfway there.

Soupmag, Sorry it took so long to reply; I had to pick my kid up from his mom's after work, and feed, bathe, and bed him, which is exhausting. I was at work earlier.
I can boot the device into recovery mode. The screen looks like this:
CWM-based Recovery v5. 0. 2 .7 FULL (By DooMLoRD)
Amazon Kindle Fire: v01-FINAL: Touch ed. by TUTRCHAOS
-reboot options
-Install zip from sdcard
-apply /sdcard/update.zip
-Wipe cache
-Backup and Rest.
-Mount & Strg
-advanced
-Power off
-Go Back

-----------------------------------------------------------------------------
I don't know how to get a new .zip on the /sdcard. The PC doesn't see the device, so I can't transfer. It won't boot normally from this (reboot options are norm., fast, recov.) so I'm left with trying to reinstall the .zip, but I don't know if I need to wipe b4 I try that. Or, factory reset and hope it starts in Kindle launcher. What happens next. Sorry this is so long. I just don't want to screw it up even worse or possibly brick it.
Thanks for your help and patience.

For some reason, the update will not install with CWM. I found that if you install TWRP, the update will install. I have used the commands on this page http://forum.xda-developers.com/showthread.php?t=1568340 to successfully install TWRP and then the update installs. After that, you will have to re-root.

When it says in those instructions:
adb push fbmode /data/local/fbmode
is that a command prompt window in the kindle dir? Or a KFU Option?
adb push fbmode /data/local/fbmode
Something completely different?
Please elaborate.
Thank you.
-Kyle

There's no need to reroot. I assume you're using Windows, right? Fix your drivers so you can use adb to push a new rom to your sdcard OR mount your sdcard in TWRP and transfer it like that.

Ok Awesome. Soupmag, awesome. I don't want to un-root. How do I update my Drivers? I had the adb drivers working fine yesterday. I didn't change anything. I'm using the KindleADB drivers and when it worked. I plugged it into the PC (windows vista) it would show under ADB devices on device manager.
Thank you,
Kyle

Well first, see if you can get into recovery and mount your sdcard (Kindle plugged into the computer of course)

Ok, I'm on recovery CWN-based Recovery v5.0.2.7 FULL
There's an Android Composite ADB interface under Android Phones in Device Manager
USB plugged in of course
Edit: When I shut the device down the Android Phone>Android Composite ADB Interface is removed from devices in device manager, so it has to be seeing the device, right?

Command prompt window... from the directory where you unzip the files. Honestly, I don't really know if all the steps are required. All I know is that the process has worked for me.

While in recovery, select "mount sdcard". It should show up on your computer as external storage. Then use your computer to download whatever rom you want and transfer it to your sdcard. Just make sure its in .zip format.

Stuck in boot loop after failed root.

i was curious to get get android market on my kindle today.. and looked up how. i used the kindle fire utility to root it. then my KF it started to go into a loop of the boot logo. it just flashes on and flashes off over and over again.hard reset doesnt affect it at all, it wont even turn off unless i unplug it. it doesnt show up on my computer either.
i dont know if this helps but when i ran the Kf utility it said 'findstr' not recognized.. blah blah blah. and it didnt give me the 1234567 options on there. i just typed in '2' and pressed enter because thats what the video told me .-. it doesnt have a triangle, or a blue screen logo either just the kindle fire logo flashing off and on. I honestly am lost. please keep this noob friendly
i am running win 7. 64 bit.

It seems like your stuck in fastboot mode. You need to reinstall the drivers manually and then go into KFU. Press 1(bootmode)and 1(normal). If you still want to root it, when it gets to installing fff, and if it says <waiting for device>, you need to do a hard reset and your Kindle, unplug, plug it back in, and manually install the drivers. Then it will finish rooting.

How do you reinstall the drivers manually? and also when i go into the kindle fire utility it doesnt give me 1,2,3,4,5,6,7 options... it just says findstr is not a recognized as an internal or external command, operable program or batch file. and another thing i tried another utility on here and it said it said my device was not found when i plugged it in , is it because it turns off every 5 seconds?

First before you mess with your drivers shift+ right click on the tools folder in kfu select open command window here power your device off completely leave it unplugged type fastboot -i 0x1949 getvar product when it says waiting for device plug in your powered off kindle it should then power on in fastboot mode if you get the response product: kindle then type fastboot -i 0x1949 oem idme bootmode 4000 it will say okay hopefully the type fastboot -i 0x1949 reboot it should then reboot in normal mode
Edit: hit enter after each command

Sounds like there's some sort of PATH problem with your setup, which is why KFU won't work properly. You'll have to manually use ADB/fastboot commands if you want to get things done.
About it turning off constantly, it's probably out of battery. Use the stock wall charger (it provides a greater power output, don't bother with USB or a random clone) so it can refill some. The bootloops may be due to a bad boot mode, but it's a bit hard to pinpont with your description of the issue.

You might have corrupt drivers. Here's how to reinstall them:
Try going to your Control Panel >> Device Manager. If you see an entry for "Android Phone," (Android ADB interface) delete it (and any associations with Portable Devices >> KF or Kindle Fire).
Restart computer.
Then go to your KFU utility folder, open "install_drivers.bat" (right-click "Run Administrator"). This shouldn't take long at all.
You might want to restart here too after.
Then open KFU utility, plug in Kindle - if all went well here, you should read something along the lines of "Online" and "4000".

I am a similar situation
Hi Guys,
I rooted my KF with no issues, was able to copy the Jellybean and Gapp zip file to the SD and thought I flashed with no issues. Then rebooted. Now the KF is stuck in a boot loop. If I boot to recovery, that works and allows me the recovery options. if I boot up to normal, it constantly reboots, if I boot to fastboot, it displays the Kindle Fire logo and says "press power button to boot menu" at the bottom and does nothing else. My computer recognizes it as Android ADB interface but will not allow to access the SD ram. Any help would be greatly appreciated.

It's usually better to start your own thread here on Q&A.
Are you able to access the SD Card from TWRP? (Mount USB)
If so and the ROM is still in there, wipe cache, dalvik-cache, factory reset and system, then flash/install the ROM again (don't install gapps yet) and reboot. If it boots all the way to the desktop, reboot to recovery and install gapps.
You may also want to check the ROM's hash.
You haven't mentioned what versions of TWRP and FFF do you have, either. Hopefully 2.1.1 or 2.2 for TWRP and 1.4a (blue "fire" on the kindle fire logo) for FFF.

Thanks for the info and sorry for the incomplete initial info. I will check this as soon as I get home and can work on it again.

Thanks for your help. It turns out that I didnt even have TWRP installed. Thats fixed. I was able to get roms installed and have different problems. (Will start a new thread in another area) Thank you very much for your help.

Kindle Fire stuck in TWRP boot loop, wont mount, not recognized.

I foolishly let someone try to root my Kindle Fire, and now it is stuck in what seems to be the TWRP boot loop (the kindle fire is blue and white). If I leave it alone unplugged it will occasionally continue to the Kindle Fire orange and white screen but will not go any farther. From the Blue/white screen I can hit the power button to enter the boot menu where I get Normal Boot, Recovery, and Reset Boot Mode. I can enter TWRP recovery menus, but otherwise it just keeps rebooting. Once in the TWRP recovery screen I can only navigate for a short time before it locks up and I have to reboot by holding the power button in. The sd card will not mount, and they did not backup anything before they started messing with the os. Ive tried the Kindle Fire utility but it says device not found. The Kindle showed up in my device manager as Other-Kindle before I installed the android drivers mentioned in another thread, and now it is under Android Phone- Android ADB Interface. It doesnt show up in My Computer at all. I've read about the factory cable but cant find on in the US so it would take 2 weeks to get here from China. Any suggestions on how to fix this, or do I now have a $200 paperweight? Thanks in advance.

Maybe go into twrp and do a factory reset. Can you get to that menu? Click wipe and then factory reset.

I've tried the factory reset but it seems to have no effect on it. How do I do the adb push? I've tried using the command prompt to run some of the commands on other threads but I'm not doing something right. I always get an 'adb' is not recognized as an internal or external command, operable program or batch file error.
I'll apologize now for my stupidity on this one- I have never worked with android software before this.
The kindle fire utility reads:
ADB status: Offline
Boot Status: Unknown
I can get it to boot in normal and recovery mode, but each time I try to boot in Fastboot I get an error message 'Oops... something went wrong. We are unable to locate your Kindle Fire. Make sure it is plugged in and powered on.' The Kindle shows up in Device Manager under Android Phone as Android ADB Interface
When using the twrp, anything that involves writing to or wiping the sd card receives this error E:failed to mount /sdcard (invalid argument)
I'd appreciate any help I can get. I'm at a standstill on this one.

im in the same position you can open it as a USB by selecting mount in TWRP and selecting mount USB Storage

do you have drivers / ADB on your computer ?
I did manage to get my kindle go into a recovery boot loop by doing the root procedure for the original 6.3 original Amazon ROM while my kindle had the 6.2 ROM . After i realized that the root procedure (intended for ver 6.3) didn't work for me, I had to try the procedure for rooting ver. 6.2.
It worked but after a couple of resets, the tablet went into a recovery boot loop.
what i did was to use ADB comands:
enter windows - > start command prompt (start - > run -> cmd)
check if kindle is connected: adb devices
if the device is found then use:
adb shell
su
idme bootmode 4000
exit

Hi all, I'm having a problem with my Kindle Fire. It is automatically booting into TWRP no matter what I do.
I have wiped everything, and installed the stock ROM, and when I reboot it just goes back to TWRP.
There is always a message of *verifying file system and *verifying partition. I can mount it and move files via USB.
In the fire utility it reads
ADB Status: Online
Boot Status: Unknown
If I try to change the bootmode it comes back waiting for device. I then got into the command line.
Doing "adb devices" shows it as being in recovery. I can reboot it from here, but goes right back to twrp.
I tried to do the adb shell--> su--> idme bootmode 4000
but after I do the shell it comes back that "su" isn't valid. I'm assuming I am doing something wrong, but I can't
for the life of me figure it out...any suggestions? Thanks in advance!

At startup hold thepower button untill you see the bootmenu come up and select "normal boot"

On the Kindle itself you mean? There is no bootmenu. I get the Kindle Fire (Orange) text, then goes straight to twrp, and if I do normal reboot from there, just straight back to twrp.

Tried it, no go.

This is what I get in the command line

The "<[6n" is likely the result of pressing the up or down arrow with number lock turned off and it is causing the command to be unrecognized.

Regardless, there's no need to use the "adb shell su -c..." command to get into fastboot. Instead use Pokey9000's bootmode binary "fbmode".

As you can see, the "adb shell" command is successful because of the change in the prompt.
~ # <-indicates the shell is working and active, so the actual /path of adb is irrelavent.

Cant mount SD card on kindle fire.

So I was messing with my kindle and it was trying to upgrade it to jelly bean and i guess i missed one of the steps and bricked it. I was going through the process of unbricking but when i was trying to do extract the update.zip folder it would not allow me to because it could not mount the SD card. All i need to figure out how to do is get the SD slot mounted. I am slowly picking up on command prompt and still trying to figure out adb shell but that is all i need help with.
I can unbrick it if someone knows how i can get my kindle to mount back to my computer!
Any advice or step by step for it would be very helpful, Thanks guys

Forgive my redundancy but please describe the "boot loop". Does it just sit at the Kindle Fire logo? Does the Kindle Fire logo flash, or change brightness? Does it make it to the boot animation? Black screen?

It will go to the kindle fire logo and then it would go to a black screen. It makes no boot animation. It will change some brightness. The words kindle fire are in white and blue. It flashes where is needs to do the boot animation and then just goes to a black screen

The image shows a very low battery. The behavior you describe suggests a low battery. You're in a boot loop caused by no power.
Let it sit for several hours (better...over night).

It might be a good idea to consider installing TWRP rather than using CWM. CWM is known to have problems with some newer ROMs.

Hey were u able to fix it??
Had the same problem with mine when I used TWRP to format my SD card..but was able to solve it..
What I did was a very simple thing..got the kindle recognised as a drive..used windows partition manager to format it
It worked.. I tx the stock and installed it
Try it and let me know

I had the same problem before and only had to reboot the kindle.

Nothing is working. i have given up all hope. Like this is crazy. It is screwed up for good. I cant get it to mount. If anyone wants to take a shot at it just shoot me a pm with an address and we can discuss something about trying to fix it or what the hell i did to it. Its crazy! and really messed up.

I have an Idea. If you have fastboot working on your computer. You could try flashing a rom from your computer by typing
fastboot -w(wipes device)
fastboot update <path to rom> (flashes rom)
If it works, you can then fix the sdcard easier with adb/shell/partition manager. Its worth a shot.
I also found this on a website
ROM update without SDcard
If you don't have an sd card, or your slot is broken you can try this trick, but you will need a custom recovery like Clockwork.
Boot up your phone to recovery. And move your rom file to the adb directory, and start a command line ( cmd )
adb shell
mount data
adb push D:\custom_rom.zip /data/
Wait until the push finised, and restart your device to recovery again with "adb reboot-bootloader"
mount data
mount /data /sdcard ( mount the data folder into your sdcard folder, so your recovery will think that you have an sdcard installed )
Locate the ROM .Zip file you wish to flash.
Confirm the flash by following the on-screen instructions (ie: pressing the trackball, pressing the call button, etc.)
If no errors arise during the flashing process then the ROM flash was successful, Reboot the device.
With some root file explorer, remove the rom file if you don't need it anymore, to free up space.
Or use adb to remove the custom recovery
adb shell rm data/custom_rom.zip

I will give it a shot. Only thing is i dont think there is even any software on here. when i try to get it into fastboot mode here is what it says.

Then you need a factory cable to get into fastboot.

- exec '/system/bin/sh' failed: No such file or directory (2)
It means you don't have access to the shell in order to switch bootmodes and access recovery, which is needed to fix this type of problem. The only way to change bootmodes without access to the shell, is in fastboot. Unfortunately, you need access to the shell to change the bootmode to fastboot as well...catch-22.
For this, you need a factory cable. The factory cable will tell the device to boot into fastboot without the need for a shell. Even with a factory cable, and access to recovery, you'll still likely need to either reformat, or repartition your sdcard in order to get it to mount.

Can't mount SD card on kindle fire
I was in a similar situation and after reading the various forums i came across this action "hold down the power button until the kindle goes off and continue to hold for about 30 seconds I believe this resets the kindle and then tick debugging and mount usb storage the sdcard will open on your pc" and then you can go from there. Worked for me so good luck.

Erased EVERYTHING

I accidently erased everything from the KF2, all I have on it now is the recovery.
How can I get a rom back on the device?
When I plugged it in the computer under Device Manager it says Portable Devices >> F:/
When I go to my computer to try to enter f:/ its inaccessible.
How can I fix this?
Thanks!

Same issue here. Understood the instruction to wipe everything before installing ROM to mean "System" and "Internal Storage" as well. Now the downloaded ROM and "gapps" zip files are gone...
Found something called "ADB Sideload" in TWRP, could that help?
Like the OP, would appreciate some help. Kindle is a brick for now...

Back Up & Running
First You need a Fastboot Cable.
Run The Recovery Tool. (Options 1 then 2)
When its completed unplug the Fastboot Cable and press and hold the power button until the KF2 turns off.
Turn it back on and you are all set to Root it!
Rooting

OK, thanks LEGEND94, that helped !
Only difference to above: did not use a Fastboot cable to get into fastboot mode, rather fmkilo's technique here: http://forum.xda-developers.com/showthread.php?t=2117224
Held off button to shut down and restarted without having to do anything else, did not have to type any command to get out of fastboot mode.
Am restarting root and ROM flashing, hopefully will work this time.
Thanks again,

even though legend was OP, his method was a bit overkill, but totally fine.
Once you have recovery, or even the bootloader, you should NEVER need to restore. From the bootloader you can get into fastboot now, and from fastboot you can get the recovery.
As for putting files on, I'm not sure. I could look it up but you both got your issues solved. If someone coming here does need the help, PM me and I can look it up, but from what i remember on other android devices, usually the recovery somewhere has an option to mount USB like a storage device (probably bad wording there) but basically just like when you "turn on usb storage" in the android OS.
I am ASSUMING TWRP has something similar, and if I'm wrong, I'm sure you can always ADB to push the files onto the device from your PC in fastboot mode.

Unfortunately usb Mount doesn't work in the kf2 twrp. I would love the option.
You CAN adb sideload from twrp though.

What I did above is the easiest way, the sideload didn't even work!

One change to the above statement. I did have to get out of fastboot mode, but it was confusing how because the terminal emulator was now gone.
I did this instead via a command window with the Fire plugged into the computer. I sent the "fastboot -i0x1949 oem idme bootmode 1" command while in the root directory for the KF2_SRT_10.2.3 restore package, there is a fastboot.exe file there.
Hope that helps.
