KF HD Stuck at Kindle Fire Screen

Hello, I have a rooted Kindle Fire (with bootloader) and tried to return it to original Amazon Stock OS.
I tried the steps specified on this page androidcowboy.com/2013/06/how-to-return-kindle-fire-hd-to-stock/
After this steps:
"Navigate to the folder where you unzipped the Kindle Fire SRT Tool and double-click on “SR Tool” file. Choose option 1 for “Restore-Factory Rooted with Superuser.apk”. Be patient as it’s very important. The file transfer can take up to 5 minute with no progress notification. If you interrupt the process in any way then you will BRICK your device. After the transfer is done then choose option 4 to “Erase cache and userdata”. Once it’s finished then choose option 6 to reboot."
It rebooted and seemed to be stuck at the white and orange Kindle Fire logo screen. I can turn it off and on by holding the power button, but my computer cannot detect it as a portable device or ADB. But I can enter fastboot mode by plugging the USB while it is turned off, so I don't think it's hard bricked.. I hope so.
Any thing wrong that I have done? Sorry I'm a noob when it comes to this. Help please?
Btw, my Kindle Version 8.4.1

Is it boot looping on the animated kindle logo or the static image one? Cause either way I'm guessing something went wrong with the flash, you should probably reflash the boot and system images, try using kindle fire first aid if the SRT doesn't work, I believe it has a stock rooted image flashing option like SRT. BTW don't confuse boot with bootloader, boot is where the kernel is stored. Just pointing this out because if you don't need to flash the boot loader then u shouldn't, if it corrupts you have a hard brick.

I do have KFFA, which option should I choose? And mine is stuck on a static image one.

Weird sounds like it doesn't want to even try to load the os, maybe some things wrong with the kernel, anyways I haven't ever used kffa, but there should be an option somewhere to restore system image. You will first need to get the device into fastboot mode, just open a command prompt and CD into the kffa directory, I should have a fastboot command, and run this: fastboot.exe -i 0x1949 getvar product
Then plug your kindle in with the power off. If for some reason it doesn't work, which it should because you seem to have flashed something from fastboot before, then u will just have to update a driver before it disconnects.
Edit: OK fixed sorry for the thread mix up.

Same problem
I have a KFHD 8.9 with the same problem as the OP. It's stuck on the static (orange) Kindle Fire logo. I have working drivers and I am able to get it into fastboot using "fastboot.exe -i 0x1949 getvar product". The problem is, I don't know any of the history of how it got this way. I have repaired a lot of Generation 1 KF's and I thought I would get started on the Gen 2's so I bought this on eBay this way. I didn't realize how much more risky it was to work on the Gen 2. I also have KFFA working but I can't figure out how to get the stock image onto the KF so I can flash it back to stock. When I go into fastboot mode and use KFFA to reboot to normal more it just stops on the static Kindle Fire logo. Also, I can't get ADB to work at all. Any help would be greatly appreciated.

There's an option in kffa to restore the system partition, should be a fairly obvious choice, if you can't find it try the kfhd system restore tool

Well I tried KFFA Option 7 - Completly Restore the KFHD 8.9 8.1.4 (Fastboot) but it didn't work. There is a problem in RunMe.bat with the wget command when trying to download the .img files from dropbox:
Connecting to dl.dropboxusercontent.com|174.129.21.126|:443... connected.
ERROR: cannot verify dl.dropboxusercontent.com's certificate, issued by `/C=US/O

Unable to locally verify the issuer's authority.
To connect to dl.dropboxusercontent.com insecurely, use `--no-check-certificate'
Unable to establish SSL connection.
So then, I Downloaded the KFHD_SRT tool and managed to restore the system partition but it still would not boot. Then I saw down at the bottom of the instruction page that to downgrade to 8.1.4 you also need to restore the boot and recovery partitions. After I did that -- PRESTO! my KFHD 8.9 booted up and is now working.
THANK YOU SO VERY MUCH FOR THE HELP!!!!! I will be sure to click the "THANKS" button.

[Q] Stuck on fastboot and need new ideas on recoveries

So I bought a 8.9 KFHD Demo unit. I gained access to fastboot through command prompt and have all the drivers installed. Stupidly, I used the KFHD System.img Recovery Tool for the 7 inch model on it and subsequently it boots up and says Kindle Fire for a few second, a red screen washes over, and then it says fastboot and stays that way. I then proceeded to erase cache and used the KFHD System.img Recovery Tool for the 8.9 inch version, the one I have. Sadly, it proceeds with the recovery but my kindle is still stuck booting into fastboot mode. Anyone have any ideas? Or did I break it for good.. Thanks for any help

You try "fastboot -i 0x1945 reboot"?

I think you meant 1949, and yah it just reboots it and it boots into fastboot mode, plugged into my PC or not.
Edit: I also saw your other post in a similar thread about restoring stock boot loader but requiring the check of md5sum... was going to try that but wanted to ask if I am checking that the md5sum of the stock bootloader is the same as the one i am downloading?

Well that's one way to look at it because they should be identical if its the same version boot loader, but the md5sum is supposed to match the md5sum listed on the download. Also yes I made a typo in the previous post, thanks for pointing that out. You can also try something like "fastboot -i 0x1949 oem idme bootmode 1". For the record I don't remember which idme number is normal boot on the 2nd gen devices. The original kindle fire's had a different set of numbers for idme, but I believe the 2nd gen kf's use 0-3, so you might have to try a few numbers to get it right. I looked it up somewhere before and I believe found which one was supposed to me normal boot, but I don't believe i can look far enough back in my posts to find it via the xda app I'm using.

Neither 0-3 do anything, on my kindle. Although, each one says finished in the cmd prompt. Should I go ahead and tr flashing the stock loader on? or should I of done that before trying your line of code.

You didn't necessarily need to flash the boot loader beforehand, and did it reboot after issuing the command I mentioned? If not did u try a simple fastboot reboot afterwards like I Initially said to do? You just need to be careful if you are going to flash the boot loader, like I said make sure to check the md5sum and of course make sure its the boot loader for your model.

None of those commands did anything but I did do the reboot command and it rebooted back into fastboot mode. I guess I will try to flash the stock bootloader now...

So after trying different recoveries I have gotten my kindle out of fastboot but now it is stuck on the Kindle Fire System Recovery screen asking me to reboot or reset to factory defaults because it failed to boot(neither option fixes it). I tried the KFHD System.img Recovery Tool to no avail. Not sure what to do now. Do i need to flash the complete stock OS to it?
I used KFHD First Aide to get to this point. After I use it though, on the recovery screen I get a bunch of errors saying it can't mount cache. On the KF First Aide bat file prompt it says it erased cache, then attempted to format it but it's not automatically formatted as the file system type is not supported. I am wonder is these things are related.

Try running kffa one more time, it usually goes to recovery when something is messed up with the system partition, so try another reflash.
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app

Same thing happens. Says it didn't automatically format userdata or cache and then when the kindle boots it goes to recovery and the errors says" E:Can't mount /cache/recovery (Invalid argument)
because kffa downloads the files it flashes do you think those were corrupted? It only downloads them once so when i run it again its flashing same files.

Ah well that could be the case, but this error seems to be an issue with mounting the recovery partition which is weird because recovery seems to work fine, at least I think its trying to mount recovery, though that is in the cache path so I have no idea. Might have to ask soupmagnet about this.

hi I have the same problem you once had I have kindle fire hd 7 I two am in this boot then red screen then stuck in fastboot how did you fix this any help would really help me many thanks

You should try reflashing the bootloader, just make sure you grab the right bootloader for your device and check its md5sum against then one listed on the download. If you don't check the md5sum you are liable to hard brick it. From there it should be as simple as flashing the rest of the partitions from fastboot and hoping it works.

[Q] Can't get ADB to communicate with Kindle Fire 8.9 HD

Hi folks. I've been studying the forums for a few days now and can't resolve my issue. Hoping you will tolerate a noob dilemna.
I have a KF 8.9 HD running CM 10.1 and play store with no issues. Runs flawlessly. In my attempt to try out the CM 10.2 I wiped out the internal memory, cache etc.
I'm using Windows 8.1 to communicate with the KF.
I can only see the Kindle and use the ADB commands if I boot into TWRP. It reports the number and recovery when I run ADB devices in an admin command window. I'm unable to use the ADB commands when the KF is running the 10.1 OS desktop. Windows device manager reports it as MTB USB Device instead of the ADB Composite Device I get when it's running in TWRP. No matter how much tinkering and uninstalling KF drivers, I can't get it to see the KF.
I've also downloaded KF FirstAide.I get all of the menu options but it hangs whenever I try any options. For example, it hangs after reporting daemon started successfully when I try to use the safe diagnostics. I can't get it to communicate with the KF.
I'm in need of restoring this KF 8.9 HD to Amazon stock OS. I've ordered a new one and will be passing this one on to someone that's looking for the Amazon stock system. Otherwise I'd leave it as it since CM 10.1 is running.
Really appreciate the help you can give me.

You have to enable adb in cm 10.1, click on the build number about 10 times under "about tablet" in settings, that should enable the developer menu in settings so you can enable adb.

Thanks Stunts. That should get me closer to figuring this out. The {} Developer Options are now visible on the KF. Root access is set to Apps and ADB. Uninstalled KF Win 8.1 device drivers again and rebooted both KF and computer. Still doesn't see it in Win 8.1 when I use ADB Devices (doesn't report any devices).
The Windows driver is still reporting MTB USB Device. When I try to update the driver using androide_usb.inf windows reports there is no compatible software driver in that folder.
I'll keep messing with the Developer Options on the KF. Any other suggestions?

Stupid question but did you check the box to enable adb? I didn't see that said you did only something else so I thought I'd ask. Also the MTP device is desperate so you shouldn't have to update it with the adb drivers, it should be a desperate device usually under its own android debugging category if I remember right.

I gave up on getting it to work in Windows 8.1. There must be something about the way it handles the drivers that prevents the device being seen when CM10.1 is running. Very frustrating. I must have tried 100 different variations but I can only get it to see the KF in Portable Device Player, not the Android Composite Device it sees when I'm running in TWRP mode.
I ended up using my daughter's netbook which is running Windows 7. Installed Java Developers Tools, KF First Aide. I can now see finally both the device as the portable media player and the Android Composite Device. Yeah!
One last problem to overcome. I want to wipe the KF clean and install the stock Amazon system. KFAide now communicates with the device in CM10.1. I was able to do a backup but it still hangs when I try to restore the stock system.
Is there a place a can get the stock image files for KF 8.9 HD? 8.1.3 or 8.1.4 should be fine (I don't remember which I was running before installing CM10.1). Ideally I want to transfer the stock images to the SDCard directory and then use TWRP to reinstall. Sound reasonable?

If you want full unrooted stock just download the latest update from Amazon's website for your device, put it on the kindle's sdcard and change the extension to .zip, and wipe the system, and do a factory reset then flash the amazon update, it should remove twrp and 2nd boot loader as well

Thanks again Stunt. Want to make sure I do this correctly.
Do I just check off wipe system in twrp or other items like internal memory etc. I'm thinking just system.
Is the factory reset from within twrp?
Finally, do i flash while in fastboot mode?
Sorry for all the questions. Appreciate the help

When you hit wipe I believe there is a factory reset button, and after that you would do another wipe and check system, then install the amazon update zip file from within twrp, not fastboot.

How to Disable Driver Signature Enforcement to allow installation of Windows 7 Printer Drivers on Windows 8 http://www.fotoclubinc.com/blog/how...on-of-windows-7-printer-drivers-on-windows-8/

Crap! Now it hangs on the Kindlefire screen (orange color not the blue rooted color).
I can use KDFirstAide to get it back in fastboot mode. I tried the various options to restore su, erase cache and user data etc, but nothing. It continues to hang at the KindleFire screen
Any suggestion? Are there any Fastboot commands I can use to restore and use twrp again?

You need to run "fastboot -i 0x1949 getvar product" with the kindle unplugged and off then plug it in when it says waiting for device, that should put it into fastboot so kffa can restore the system.

Tired it and ran KFF. KFF prompts me that the Kindle Must be Powered on to the Desktop to do a restore of the system. Can't get to the desktop at this point. If I select no at the desktop prompt it starts the deamon and hangs at that point. Probably because it's trying to use ADB which is not active in Fastboot mode.
I was successful in using KFF to do a backup restore, but it is still hanging on the KindleFire screen.
The only thing I can do right now is get to Fastboot mode using the KFRecovery utility and Enabling Fastboot to get to Fastboot mode.

Something didn't restore right then, have you tried kindle fire system restore tool? http://forum.xda-developers.com/showthread.php?t=2011126
Is fastboot mode working as far as you know from running the command I mentioned? It should report something back with jem in it .

Fastboot is still working. I did run that command you posted: fastboot -i 0x1949 getvar product. It reported Prod: Jem-PVT-Prod-04.
I have tried the Recovery tool you linked to but it hangs when I try to restore the system (using any of the options)
Update: I was able to get KFFirstAide to complete it's recover using 8.1.2 option. I got a full red screen then it booted to the Fastboot Mode Screen. I feel I'm getting closer. I held the power button for 20 seconds, then release for 5 and power up again. It's still going into Fastboot Mode. Any advice?

Try restoring the system one more time, if that doesn't work you might have to reflash the boot loader. You can try "fastboot -i 0x1949 reboot" or "fastboot -i 0x1949 OEM idme bootmode 1" possibly followed by the first command. I have my doubts that command will work though and I'm not positive if system is 1 or not because the numbers used to be different on the original all and I'm not too familiar with the numbers on the hd models, but I think its 1.

Thanks for sticking with me Stunts. I tried reinstalling it already. Tried both variations of the fastboot commands you listed. Is it possible the second one is missing an argument? When I enter it by itself it comes back as listing all of the fastboot options (I usually get that when I type something wrong).
So it sounds like I just need to get out of the Fastboot Mode. It always shows a full red screen before entering Fastboot Mode

Odd, I suggest reflashing the boot loader then, download the boot loader for your device here: http://forum.xda-developers.com/showthread.php?t=2128175
Its the 8.1.4 boot loader listed, make sure you check that the md5sum matches what's on that page or you could hard brick it.

Appreciate the help. I tried that recovery tool a few times. Just curious, which option should be selected in that tool? I think I tried them all already, but which one should be used to completely restore? Option 1 enables fastboot (got plenty of that...lol). Option 2 restores SU. Option 3 restores SU and other stuff i don't recognize. Option 4 had google stuff I don't recognize. But I did try all of them.

[Q] Stuck in fastboot mode

Hi, I successfully rooted my KF HD 8.9 with instructions found here
http://androidroot.org/watch_video.php?v=A7HRK4M23YG7
But am now stuck in fastboot mode (displayed on screen). I did have twrp installed and got the blue logo, but not anymore.
I tried KF First Aid, under the option “Display Fastboot Status” I get
“product JEM-PVT-Prod-04
6498000040002FFF fastboot
If you see output above it looks like fastboot is enabled”
Device Manager shows under “Kindle Fire > Android ADB Interface”
Have I bricked my Kindle?
Any help greatly appreciated

Its not bricked, though I would attempt to restore the system partition with kffa since 2nd bootloader is gone. You should be in fastboot mode so that's good at least.

Download Kindle Fire First Aid, find the option about restoring, and if it asks something about is it in fastboot already say yes(or if it asks to put it in fastboot mode say no as it should be already).

tried that exactly as you said, everything seemed to go ok, but when it rebooted it sticks on the kindlefire (orange) logo

Try using SRT instead. Ignore the adb command it lists, that's only for if you have a working kindle that can boot up fully, just stick it in fastboot again and use this utility and see if you have any luck.

Hi, I've tried about 10 times to download KFHD_SRT_v2.0.zip which seems to be for my device, but it fails every time
with message ' the source file cannot be read'. I have downloaded KFHD_SRTv1.3.5.zip, which appears to be for the 7" kindle.
Can I use this, or will the imgs be wrong? There are 4 in the images folder, boot.img, recovery.img, system.img, and systym2.img

The 7" version is not for the 8.9 version, you would probably brick it even worse using that... The ones on that link I sent you are the compatible ones.

that is the one I'm having trouble with, KFHD_SRT_v2.1.zip. While in Kindle Fire First Aid I checked adb and got the message 'adb drivers not installed' so removed and re-installed adb drivers from Amazon, but I still get same message.

Since removing and re-installing drivers my device in device manager now only shows as 'Kindle fire > Fastboot Mode | HD 8.9. It used to say 'ADB Interface'

Kindle Fire Stuck on Loading Screen

Hi, about a month ago, I installed the GO Launcher EX on my stock 6.3.3 Kindle Fire 1st Gen. The same day, I decided to make the Launcher my default Launcher. Later, it began to start running slowly so I hard reset it. It now does not boot up and is stuck perpetually on the loading logo.

Didn't install twrp?
If not is logo animated/changing or not.
If animated may need a fastboot cable

Then you can wipe data in twrp or reinstall stock.

I've tried to find my Kindle in KFU and it shows Offline at all times. Does this affect anything?

Kindle Fire Utility does not Root or Install TWRP/FFF with latest update, only thing KFU is good for now is Installing Drivers and Google Apps
What step are you on, what have you done?

I am stuck on the same step. Not sure the number, but I rooted, installed go launcher, and was going to install twrp with a utility (I forget which one because I have tried to use so many of them to get out of the mess I'm in) and when it rebooted my device into fastboot/recovery, it stuck on the splash screen that says kindle fire, the 'kindle' text is white and the 'fire' text is orange. My device manager says Android Phone > Android ADB Interface. From what I have read and understand, I need to have the driver showing Android Phone > Android ADB Composite Interface. I can't seem to find the appropriate driver anywhere.
The worst part about this is that I started this for my mother in law so she could have a fully functioning tablet, and now it's a warm fancy paperweight.
I appreciate any help, or just point me to the correct thread. Can't seem to find anything anywhere.

No when in Fastboot it should just say Android ADB Interface
follow my Using Factory/Fastboot Cable to Flash FFF Bootloader and TWRP Recovery
You don't need the fastboot cable, just start with step "Download ADB/Fastboot.exe Files from"
