[SOLVED] Stuck on Kindle Fire screen... (and tried EVERYTHING)

1) Yes I checked search results.
2) Yes I've googled.
3) Yes I've tried the Kindle Fire Utility, the http://forum.xda-developers.com/showthread.php?t=1356257... links options.
With that being said, here's my issue;
Got a KF a couple days ago...
Yesterday, followed some online instructions to put GO Launcher EX on there to replace the carousel deal.
Followed instructions to the T.
Restarted. Got to "Choose your OS" screen (or whatever it precisely says...)
Picked GO... then it froze.
Now, when it restarts (yes, its the 30 second hard restart), it gets stuck on the Kindle Fire splash screen.
I have tried the above utilities.
I have hard restarted.
I have fully charged and ran the battery dry and tried again.
When I use the utilities, the problem is, my PC will not recognize the Kindle (it see's it as a removable storage device, but it doesn't click over to 'Kindle', and thus the utilities can't interact with the device itself, I suppose).
I've tried different USB ports and connecters (I have 2 regular kindles in the house, too). But I know all the peripherals work through cross-testing.
Essentially, what else can I do? (I got it from WalMart, and they're currently out of stock, so I can't return it till next week, but I'd like it fixed before then if possible)
I've tried several different methods from these forums too, but I *always* hit the same snag... whenever any utility is 'waiting for device', it simply will not find it, because the PC doesn't see it properly. It sees *something* (removable storage) but not as a kindle, and thus won't allow the utilities to interface with it.
Are there any physical things I can do to hard reset it without destroying any warrantys?
Any help appreciated!

there is no need to return it
from what you say i think you have a bad launcher on it and the kf tries to start it but can't
first i need to know if you have fff (custom bootloader - yellow triangle) on it ?
then do you have a recovery (twrp) on it ?
what os/bit of computer ?

In kindle utility go to bootmodes and enter normal (4000). Just had that problem last night.

awidawad - I've tried that. It stays on 'waiting for device' forever. Please explain step by step what you did? At which point did you power on the KF, when did you run KFU, etc, etc.
b63 - I hope your right!
no - I do not have the yellow triangle.
no - I do not have TWRP on it, i have tried, but cannot get anything onto the kindle.
my PC is window7, 64bit

Do you have all the kf drivers installed on your computer? I know that when I unbricked mine I had all the drivers installed but I had to reinstall them for some reason. If you do not have them I can post them later on tonight when I'm at home. However, I have TWRP installed on mine, and Cyanogenmod 7.2, so hopefully yours is able to connect to your computer.

In order to remove the bad launcher, you need to have your device connected to your computer to remove it using adb.

ok so b63 helped me out big time here....
about 2 hours ago we got on a teamviewer session (download this if you want these guys to help you with serious issues!)
took me a minute to figure out how to allow him/her proper access to my screen
anyway
i don't understand the technical stuff
but
what i had done wrong is that i didnt root the KF before trying to install the GO... software (i think)
b63 had a heck of a time trying to discern the problem with me being about as useful as a dead fish, but get there he/she did
after much fanangaling, b63 managed to install the TWRP and ADP on my KF, allowing it to fastboot, and basically allowing it to be read by my PC, and so fixed.
im sure it would have taken b63 all of 5 minutes in real time, but using the quirky teamview and my slow net speed didn't help
still, thanks VERY MUCH to b63 for fixing the **** out of my KF, and being very helpful and patient all along!
thanks

Just wanted to drop b63 a note here that I "thanks"ed their post above - not necessarily for the post but for going above and beyond. The people on these forums are (for the most part) really great. (Too bad there have to be a few who are demanding of the developers to get this feature or that fix done faster without taking into account that the devs do this all in their free time.)

YES, search finally led me here!
Euryon, I have the exact same thing happening with my KF right now.
Do you remember any specifics of how b63 carried out the steps you listed?
b63, any chance you could help me with mine? My issue is identical with Euryon's down to the letter.

Same Problem
Could someone please help me i have the same problem

same problem here! please can someone give a step by step? My fire is unrooted and I did nothing to it except try to install the go launcher and after I selected it as the default launcher it got stuck at the kindke fire logo.

I tried the Kindle unbricking utility but it cannot find the device even after I installed the adb composite interface

also, my fire is not showing up as a kindle - it is showing up as an android device.

thanks for replying, and I have no clue how to do that. I'll search and get back .
---------- Post added at 10:12 AM ---------- Previous post was at 09:57 AM ----------
okay, I already did that by editing the android sdk(as a prerequisite to rooting, which I planned to do eventually) - so when I connect my fire it first shows up as a kindle, and after updating the software through windows and installing drivers through KFU, it comes up as an android device and the interface is adb composite. Now if I try to install TWRP through KFU it keeps switching between adb composite interface and plain adb. And both KFU and KUFU keep waiting but are unable to find my device.

also, my fire alternately shows up as a usb composite device and an android device. PLEASE help

okay I solved it with KFU (finally!) although I have no clue how I did it as I didn'tdo anything I hadn't tried earlier so, managed to install TWRP and then wiped everything and finally my fire could be read - then I deleted go launcher and now my fire is back from the grave
A big thank you to all the helpful posts at this forum - u guys are the best

Same issue
Tried rooting my KF, but couldn't change permissions and thus could not install android market. Superuser didn't do anything other than show me a log folder that had no logs. Tried to change permissions on /system and /apps with one of the file management apps on amazon and it said the device *wasn't* rooted, despite GO launcher and android interface.
Did a factory wipe to try to reroot or fully(?) root the KF, and that's when it all went wrong. Got stuck on boot loop, but KFU helped me break out of that. Now it's stuck on the Kindle Fire splash screen with no animation. I read somewhere that this was the fastboot getting "stuck."
At any rate, i have TWRP 2.0 installed and can mount and unmount the device in its interface, but it is only recognized as ADB android device, or when mounted via TWRP, USB composite device. As such, ADB commands only work occasionally - all other times it simply says <waiting for device>.
I am running Windows 7 64 bit, and 6.3 on the KF. All restarts on the KF are hard restarts, except occasionally cmd lets me fastboot reboot.
I have spent the past 2 days trying everything I have found online (2 KF unbrick applets, 15+ tabbed browsers with different threads) to no avail. I am finally posting, pleading for assistance.
Thanks in advance for any (helpful) replies. Real thanks clicking afterwards.
edit: when rerunning KFU, i kept getting the message that many execs failed because "/system/bin/sh" directory does not exist.
I don't know if that helps narrow down what might be happening, but I saw that coming up a lot in the cmd prompt.

with an emphasis on post #2. You need to know what mode your device is in by looking at the device manager and make sure your drivers are loading correctly for that mode. If you can get to TWRP, you can mount your USB mass storage device, copy a new zip file of either the stock software or a custom ROM and flash it.

Thank you. I will be trying this shortly.

fully bricked
I followed the guide and got to a point where the Kindle Fire animation was playing. It loaded up to the unlock screen and then automatically shut itself down - would not stay on when either connected or disconnected. Tried installing a ROM but still shut down. Started the recovery and hit factory reset, still auto shutdown. Tried clearing a partition as described in the tutorial and now it's fully bricked. Will not turn on when connected to computer, to outlet, to another cable.
Thanks for trying to help.

[Q] Kindle stuck at static Kindle Fire logo

Hello all,
I need some help and guidance in fixing my Kindle Fire. Some background:
My Kindle Fire was on 6.3.1 when I rooted it, no custom roms, just root so I can get Google Framework on it since I use Google Docs and the Google Market. After about a week or so, I decided I wanted to go back to an unrooted Fire so I can get access to my stock book reading app and Instant VOD.
I had FFF and TWRP on my Kindle Fire as well, running Windows 7 64bit Home Premium
After much searching, every unroot guide kept pointing me back to flashing the stock rom. So I downloaded the latest update.zip through KFU, booted into TWRP, wiped, installed the update.zip, and rebooted.
After that, I hit the Kindle Fire logo, static, and it hangs there. I power off and on, still hangs. I don't have the blue/white FFF recovery anymore so booting into recovery wasn't an option. I then connected the Kindle to my computer, opened KFU, and tried to change the boot option through option 1, and every time I change it, Fastboot, Normal boot, etc. it sends the command, Kindle reboots, but then hangs again on the static logo.
I tried reinstalling FFF and TWRP through KFU to try and reflash, but it shows as preparing, then waiting for device, and nothing. Again, just hanging.
I even tried the manual shell commands I've seen around the forums and in the Kindle Fire for Beginners Guide, but I keep hanging on "Waiting for device" in the cmd prompt.
I don't know what else to do and I'm becoming more confused with the different types of issues that everyone is reporting, with each one have one detail different from my situation. I had no custom roms, just a root, and it seems I may have flashed a bad stock rom.
Any help is greatly appreciated. I apologize if this was solved somewhere else, but I searched numerous threads and guides, but they all dealt with something going wrong with a custom rom or people getting to the animated Kindle Fire logo, where as mine is just static.
Again, thank you for your time.

Sounds like it's stuck in fastboot bootmode to this noob. I had the same problem at one point and used command line to fix with the simple bootmode switching commands - can't recall if I used fastboot or adb tools..but either should work. And if I'm reading your post right, you've tried these so this is likely above my meager skill level, heh. You are handling it better than I did, I might add.
If I may point out where you went wrong:

There are apps in the Google Play store that will temporarily remove your root status so you are able to use services that detect and shut down when root is detected. OTArootkeeper.apk is one that I've heard of.
And don't ever chose to lose fff once you have that as this is your lifeline to unbricking.
Hopefully someone with better chops than I on this will post up - continue with your patient reading and take a little comfort that this is most probably fixable.

First off, I applaud you for trying to figure out and fix the problem yourself using the guides available. Thank you. The information you provided will go a long way to getting the help you need.
So far it seems you've done everything right, but to be sure, you should check to make sure your drivers are in order (most likely the problem). The second post of the Beginners Guide will help you with that.
Once you have done that and you still can't change your bootmode, try using recovery to flash a custom rom. It's possible the stock boot image you have has been corrupted. You can use the "mount" function in recovery to push another rom to your sdcard. If that works you can stick with a custom rom like MoDaCo. It's the same stock stock interface with Google apps and services installed and you don't have to worry about OTA updates. OTA Rootkeeper will let you easily switch between "rooted" and "unrooted" so you can take advantage of Amazon's VOD.
And if you still want pure stock you can d/l a new copy of the update and try again.

Thanks for the suggestion. I did try OTA Rootkeeper, but when I went into my Instant VOD, it still had the buttons grayed out. I tried temp unroot, reboot Kindle, and still grayed out, so I assumed Rootkeeper wasn't working for me, thus, the looking for the unroot tutorials.
A little bit of extra information, when I hook up my Kindle Fire, my drivers says Android Composite ADB Interface. When I try to switch to Fastboot to have it switch to Android ADB Interface, it doesn't switch. It just stays as Composite.
Thanks again.

I followed the advice in the Beginners Guide, uninstalled whatever drivers I had, rebooted my comp, then installed the ones that came with the KFU download.
Are there any other drivers I should be looking for?
Also, a little bit of more information, I tried switching to Fastboot through KFU, received some messages to the effect of "system/some file name file not found (2)", (I apologize for not being specific, typing from memory), it then reboots my Kindle Fire, then I execute the commands:
fastboot getvar product
After that, it just says <waiting for device>
In fact, after any command I do in cmd, I get that message. So I believe it may be a driver issue, like was suggested, or my Kindle isn't far enough into the boot process to be found.

It definitely sounds like a driver issue. Keep working on your drivers.
If that doesn't work, you can try it on a different computer OR set up a Linux LiveUSB for issuing adb/fastboot commands.

FIX for Kindle stuck on logo
Finally I FIXED MY KINDLE FIRE!!!!
Issue : Kindle Fire stuck on 'Kindle Fire' logo and never moves after that.
Hello All,
Just like others in here, even I tried to upgrade to new version of Android on my kindle and I messed it up very bad.
I have read a post where, some-one just updated that it is because we have enabled fast boot on it and we need to move to regular boot.
However, none of the solutions suggest on this website worked for me (am not saying my friends are wrong in here).
Finally the work around that WORKED for me, and am sure this will be help you all.
When you are wiping/erasing the data/SD card, please do not wide the ROM. If you delete the ROM - Booom!!, you are cutting off the branch yo are
sitting ON )
Now if you have already done that.. please follow the steps.
You have intall/upgrade to a new version of Android.
Make sure you have the TWRP 2.1.x or 2.2.0 installed << which you will have, using that only you wiped off your kindle )
Now download the latest version of Andriod Jelly Bean and Google app on your computer from the following link
http://forum.xda-developers.com/showthread.php?t=1778010
1. Now, boot ur kindle into recovery.
2. Connect your kindle to your computer, if the computer recongnise your kindle paste both files onto kindle, and move to step 6
3. If your kindle is not recognized (like in my case), go to mount option in recovery
4. Choose mount USB
5. Kindle will be recognized in computer, and copy the files.
6. Disconnect Kindle from the computer
7. Wipe data/factory reset
8. Wipe cache
9. Wipe dalvik
10. Install ROM <install Andriod Jelly Bean> Do not install Google Apps
11. Reboot
Once you do a normal reboot, your system will boot into Andriod Jelly Bean edtion. Go to file manager and reach out to Google Apps and install the
application and reboot.
Yes!! you have the complete recoved Kindle
Only known issue - Your battery bar will not move when it is charging (but actually it is charging).

I am stuck at the very same place you are. I was in an endless bootloop after trying to flas back to the Stock Amazon ROM using TWRP. Once i got the drivers sorted out and ADB could see my device i used KFU to "Install permanent Root with Superuser". The KF went to reboot into fastboot and the screen said "waiting for device" for about ten minutes. Now the KF is stuck at the white and orange "kindle Fire" boot logo. Windows will no longer see the KF as an android device. It only shows up as an "unknown device" in the device manager.

Try this

Ok, I dont know, how to fix this (as I was not in this situation). Try following the steps - Download update.zip through KFU. Connect your Kindle to PC and install the android driver. If your PC detects the kindle copy update.zip file to kindle and try to install that.

Im in the same boat you are. I have tried everything stuck on same logo device is recognized in devices as android phone and adb interface but cannot connect to unbrick utility or KFU and doesnt show as a drive either. tried to search devices in cmd using fastboot commands and nothing shows either. I decided to purchase a factory cable today on ebay. Keeping my fingers crossed because after reading everything I could find I think it is my only option.

No, your problem is as "simple" as fixing your drivers so the computer can communicate with the device through adb and fastboot. KFU relies on those two tools to do pretty much anything. Unfortunately, Windows is stupid and is not very effective when dealing with certain USB devices.
In order to, say, install TWRP, you need adb to change the bootmode to accept fastboot commands, and use fastboot commands to overwrite the recovery partition. In the process of going between different boot modes, Windows had a hissy fit and decides not to communicate with the device at all. Hence the need to fix/reinstall the drivers. It doesn't always work out that way and you get stuck where you are right now. A factory cable will put you in fastboot, but it wont make Windows communicate with the device. You can continue to fight with Windows drivers and hope to get lucky, or you could try other, more effective options...

[Q] Downloaded GO Launcher w/o rooting.

"1) Yes I checked search results.
2) Yes I've googled.
3) Yes I've tried the Kindle Fire Utility, the http://forum.xda-developers.com/show....php?t=1356257... links options.
With that being said, here's my issue;
Got a KF a couple days ago...
Yesterday, followed some online instructions to put GO Launcher EX on there to replace the carousel deal.
Followed instructions to the T.
Restarted. Got to "Choose your OS" screen (or whatever it precisely says...)
Picked GO... then it froze.
Now, when it restarts (yes, its the 30 second hard restart), it gets stuck on the Kindle Fire splash screen.
I have tried the above utilities.
I have hard restarted.
I have fully charged and ran the battery dry and tried again.
When I use the utilities, the problem is, my PC will not recognize the Kindle (it see's it as a removable storage device, but it doesn't click over to 'Kindle', and thus the utilities can't interact with the device itself, I suppose)."
***
That is my exact problem. I downloaded GO Launcher w/o rooting my Kindle Fire. When I tried to open the app, I set it as default. My KF froze and now is stuck on the shining logo. I have downloaded KFU but it will not find my device. Nor will my computer.
How do i get my comp to recognize my KF again?

Have you tried reinstalling your drivers? What version of Windows are you using?

no idea
I downloaded KFU today, and that's all ive rly tried. It wont read my device. I don't understand all the tech stuff. I have no idea how to hceck my windows version. I need detailed instructions or a video.

Is my new Kindle irreparably bricked?

Okay... so I did something stupid.
I rooted my new Kindle Fire HD 8.9" ...and every worked perfectly. But then I installed Nova Launcher and encountered a number of bugs--the worst of which was that trying to move icons would result in the screen flipping upside down. So here's the stupid thing: I tried to unroot it without looking online.
So, first, from the Kindle Launcher I restored the system to factory defaults. That god rid of a lot of the stuff I'd added, but the system was still rooted.
So then I looked online and tried a few things to no avail. Then I finally tried the "correct" method to unroot--b4nary's binary utility--but was unable to do so. I looked online further, found nothing remotely helpful, and then decided to re-run the binary utility under the assumption it'd be like reinstalling software... (yeah, guess that's not the case).
So, anyway, that's what I did.
I ran the .bat, chose restore my data, and then the Kindle rebooted in it's super-sluggish form.
And that's where I'm stuck.
After the unlock screen I get a "complete action using" window for Home (default launcher) and Nova, and an error message on top of it saying "Process system is not responding. Would you like to close it?"
If I choose Home to launch, for example, I get another error window saying "Activity System is not responding. Would you like to close it?"
And I can still access all of the directories on my Kindle via My Computer.
...
So, I've heard that so long as your Kindle is at-all responsive, it's not bricked... but at the same time, I can't seem to find anyone else in the entirety of the Internet to have had the same problem. I was stupid, I know that... but does anyone have any ideas on how I might go about resolving this problem?

Personally I would try reflashing the system partition, because I don't know exactly what broke, never seen the system process crashing. Might be fixable using a different method, but unless someone else knows exactly what happened I would reboot in fastboot and use the kfhd restore utility in the 8.9 inch kf android development the section. It will be pre-rooted though and without the alternate launchers installed, but you can always put those back on.
You have rebooted the kindle right?
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app

Okay... I've made some progress. I was able to boot up Nova without getting any non-responsive errors, and from there--slowly, haltingly--was able to wind my way to the settings menu and select "reset to factory defaults." So that whole process went through and I now (finally) have a responsive Kindle.
I can boot into either Nova or Home.
The problem is, I'm missing many of the programs/applications that were part of the rooting process.
At this point I think, since I can't get b4nary's tool to unroot, I'm best off just trying to re-install everything (all that Google stuff post-rooting) and try to make the best of things. It doesn't look I'll be able to unroot without buying a special cable.
Is there any way to... I don't know, run like a diagnostic of the OS to verify that everything is functioning properly?

Okay, so I installed the various Google utilities needed as a prereq. for Google's Play Store... but quickly found I couldn't use ES File Manager fully.
As far as I can determine, the chief problem I am facing now is that the Super User application--the one that's installed on a properly-rooted Fire--is no longer on my machine... and AFAIK the only way to put it on there is to use the .bat utilitity that was the cause of all these problems in the first place.
EDIT:
Messing with the Kindle further, there's some weird stuff going on. In addition to not being able to fully use ES File Explorer, I cannot uninstall the Nova Launcher... which will not function in the first place without rooting... almost like it's only half-rooted.

U can't uninstall it because its on the system partition, and has to be for the kindle to let you use it. The system partition mounts in read only mode by default and needs root to remount in read/write mode so you can delete it.

So... what do I do now? I've been able to install Chrome, but can't install Google Play Store w/out being able to use ESFE to move stuff around inside the partition explorer, and I can't use the batch file to unroot the Kindle because it's only half-rooted and doesn't have the necessary SuperUser program (and d/ling Super User and Super SU .apks hasn't helped anything)--and, of course, trying to re-root via batch half-bricks the thing.
So... would reflashing the system partition effect anything, and if so, how exactly would I go about doing that?

Well let's put It this way, reflashing the system partition isn't going to wipe many of then apps installed or their settings or the contents of the sdcard, all it does is reflash the system partition to stock rooted, no launchers and I think it also doesn't come with Google play and its framework, so make sure to install kindle free before you do this, makes life easier after you flash it to get Google play back up and running. Since I believe the kfhd doesn't work with a fastboot cable simply plug the kindle in with USB debugging turned on, and run the command from an command prompt that's cd'd into the same folder as an adb command, like the folder binary's root comes in, and run the command in step 2 of the kfhd8.9 system restore utility. On another note, when the kindle boots into fastboot, if your PC doesn't find many drivers compatible with the device, download the drivers from my signature, and go to the device manager and there would be a device with a triangle or something on it, tell it to update driver and point it to my drivers. The rest of the instructions are in the thread the utility comes from lemme get a link to it for you.
Edit: um ignore some of my instructions as i thought the 8.9" version of this tool's page was a clone of the 7" models page with a 8.9" set of images and I was wrong, its even more straightforward than i thought. Just shut the device off and when u launch the tool hit enable fastboot, then in plug you device in. Tell it to restore the kindle, and it even has the option to install the Google play store and framework for you. Here's link: http://forum.xda-developers.com/showthread.php?t=2011126

Hm... that seems very promising, but no luck so far.
I run the batch and get stuck with it "waiting for device," even long after the Kindle shows up in My Computer. Guess I'll try re-installing the drivers and retrying the batch file a few more times.
EDIT: Well, re-installed drivers and rebooted. Now My Computer isn't recognizing the Kindle at all, and the tablet is displaying a USB Compatibility error and informing me that some computers require third-party software to interact with Kindles.... it's almost funny how every single thing seems to be going wrong for me.
EDIT2: After playing around with it some more, it seems that the PC will -ONLY- recognize the Kindle (and the Kindle will ONLY not give me the USB compatibility message) when I have the drivers that auto-install from the Kindle Fire itself... using the ADB drivers results in the opposite, and SR Tool does not recognize the Kindle in either case.

Okay, several installations and reboots later and I got the drivers working properly and was able to run the SR Tool.bat utility. I was able to run 1, 3 and 4 no problem, then hit 5 and during the reboot got stuck on the loading screen.
Did it again and just did 1 and then 2 and then ended with 6.
*BTW. the options were:
1. Enable Fastboot
2. Restore-su/Supersu.apk only
3. Restore-su/Supersu.apk, Apex Launcher, phonesky.apk/vending.apk
4. Erase cache and userdata
5. Install GoogleServicesFramework.apk
6. Reboot Normally
0. Exit
Once again, rebooting takes me to the loading screen and I stay there. It's quite frozen.
Since this utility is able to do fastboot, is there any way to just clear the whole system out--get rid of all the rooting stuff and return the Fire to its original unrooted form?
EDIT: the terminology I keep see used with the SRT is "flash the system," but what does that even mean? Which of those 5 options flashes the system?

Odd maybe this isn't the right utility, it was labled the same in the android developments all about the kindle fire HD 8.9" page, lemme see if I can find the right utility.
Edit: on second thought just use kffa, its more universal, and it does what you need. http://forum.xda-developers.com/showthread.php?t=2096888

I tried to install twrp and now my kindle fire hd 8.9 and now it does a boot loop

I tried to install twrp and now my kindle fire hd 8.9 and now it does a boot loop. I've tried to get into the fast boot or use the kindle fire unbrick utility but the reboot doesn't let it get a chance to connect. I believe I used the wrong twrp version and or messed up with a setting in the kindle flash app. I bought a factory/fastboot cable and want to know how to fix this. It's not here yet but I want to know how to fix it despite this. I've tried the majority of methods including the kindle utility. When I go to recovery it just hangs on a black screen. My computer recognizes it but ADB/Kindle Fire Utility do not. my PC recognizes it with a funny name and lets me open it and it's files. It's rooted and I don't know how to check bootloader. Thanks in advanced!

I am new at this myself, I was stuck in a bootloop myself & I to had trouble getting ADB to work, sounds as tho you don't have the drivers installed yet. The part in the directions that seems to be left out is to click on "show all" then click next. I waited forever for the list. So, control panel> device manager> (right click on the troubled device) >update drivers> pick from list> click " SHOW ALL"> hit next then at the bottom> wait for it, wait, waiting. When the list comes up, go down to Google and click it> click next, i think it was, then you should see ADB drivers. If it worked you should now see your device in the device manager under Android device. Now I don't remember where I got the files to bring it back to stock but, I think under one of "DragonFire's" post he had perfect directions to recover back to stock, I think the files might be there as well. I hope this helps you, I too have yet to get a rom to flash right and have used the ADB to reset a few times now. Time for me to try to again
