[Q] Bootloop after reboot - 7" Kindle Fire HD Q&A, Help & Troubleshooting

I was installing the 2nd Bootloader and TWRP using FireFlash and got distracted and did not check apply stack. This cause my kindle to bootloop after the reboot then shut off after 10 minutes. Now my kindle will not even turn on again to bootloop anymore. If i have a fastboot cable would i be able to put it into fastboot mode and run the KFHD Restore tool?

If your device will not turn on at all (i.e. no display, no sound, etc.), the only option you have is connecting the eMMC directly to a USB sdcard reader and connect that to your computer to restore the partitions with the correct images.
That probably sounds easier than it really is though:

[Q] Unbrick Kindle Fire HD

Hello,
While trying to upgrade kindle fire HD to Jellybean , I bricked my device. Now , when I switch-on it turns on but the screen shows black with backlight on. Sometimes , it shows lines on the screen but no logo or anything like that. The problem occured when I had installed Jellybean and then it never booted again.
I have factory cable now but don't know where to begin. Can anyone redirect me to any post which gives complete procedure how to unbrick the device?
Can I directly install jelly bean during this process.
Many thanks for your time and support.

Plug it into the your computer and then your KFHD. Fastboot should come on the screen. Now you know fastboot should be working on tablet. Now unplug and press the power button and hold for 30 seconds until the tablet powers off.
Now you want to head on over to the KFFA thread and read it a couple times. http://forum.xda-developers.com/showthread.php?t=2096888 Kindle Fire FirstAide will restore your tablet to stock (provided there are no major issues.) I would choose full restore to 7.2.3 because Hascode has a matching boot.img to make flashing a custom rom/twrp much less of a headache. http://forum.xda-developers.com/showthread.php?t=2128848 All the way down to number 4. Not step 4 of number 2, but number 4. This is if you are going to flash the rom. Otherwise, use his thread to get a rom installed.
First though, after a full restore, go ahead and root and and remove OTA from KFFA as well. This will be done with the USB cord.
Now back to the rom install. should you want to use FireFlash and flash use the boot.img explained above and use the TWRP image he has too as it is optimized for KFHD 7. Make sure to drop the rom on the root of your SD card before flashing it in case you bootloop into TWRP. This way you have something to flash.

I tried to use the tool . After installing the tools and setting. I connected cable between KFHD and PC and I could see fastboot on the screen. After that I open KFFA tool and choose the options for recovery.However, once the message "daemon started successfully" , nothing happens.
What to do?
I waited for sometime but it seems nothing happens.

Kindle Fire HD 7" Bootloader Damaged Help

I tried to flash twrp and install second bootloader. I followed all directions to the point but didnt realize it was a newer os than 7.2.3 So it rebooted into recovery as TWRP then i tired to reboot back to system and it got stuck at kindle fire boot. It keeps repeating and eventually shuts off. How would I fix the bootloader. Ive tried KFFirstAide with a regular micro usb cord. But it doesnt get recongized on the computer. Should I buy a factory cable and proceed? Or do I have all needed supplies. Also when i get the kindle up and running how would I go about installing the 2nd bootloader + TWRP? I was thinking of downgrading then flashing but I'm not sure how. Thanks in advance!

You are seeing the blue logo still right? Just turn it on and immediately start holding volume up, just keep holding it till you see twrp logo, from inside twrp you can push a rom to flash over adb using a tutorial i made, its in the 7" general section towards the top atm.

If your kindle fire logo never turns blue you arent getting into twrp. You will have to use a fastboot cable to fix it with kffa or srt.

Is there any way to fix the boot loader without a fastboot cable? Also what is srt I haven't heard back of it. I have kffa installed. So that is always an option. If there is no other way I will be buying a fast boot cable

you have to have a fastboot cable to get it into fastboot mode, not the case on the 8.9" models, but on the others it is, sorry. srt is Kindle Fire Sytem Restore Tool, does the same thing as kffa except the images come with it which is useful when the mirrors for the files that kffa use take the file down.

Kindle Fire HD 7 (Tate) bricked beyond my wildest dreams!!

Hey all,
I am in quite a conundrum. My Kindle Fire HD 7" tate device is bricked. Let me explain what I have done so far...
1. I first installed TWRP using the standard and I was planning to install CM 11 on it
2. I accidentally deleted the CM 11 rom files while doing a wipe on TWRP
3. Tried side-loading the rom but somehow ADB sideload didn't work and the device was not being recognized and sideload would hang for hang (tried waiting as long as 1 hour)
4. Then I tried to reinstall FireOS using the KFDH System.img Restore tool from the forums here and managed to somehow uninstall TWRP and get it into a infinite logo loop
5. So tried using various methods to reinstall either TWRP or FireOS and after some 3-4 different utilities that I found on the forums here, I finally tried Kindle Fire Utilitiy 0.9.9 to unbrick it. Tried changing the bootmode to recovery (5000) and have managed to brick it for good.
We are now in the present day (after step #5). As soon as I turn on the Kindle, it shows KF orange logo and then switches to Fastboot mode even though the Factory USB cable is not plugged in. Once I plug it in, it goes into infinite loop with screen going off and windows giving me a constant USB plug-in and un-plug sound. The device is being detected as OMAP 4440 (or 4400?) and I am unable to do anything at all. Have I gone to no-man's land? Or can I still salvage the kindle?
Looking for some help... Any help :crying:
You should plug in the fb cable with the Kindle powered off. See if that gives you a stable fb state wherein you can push your files via adb.

Hey when I plug it in to the fb cable it boots up into the orange and white kindle fire logo and goes into fastboot and then starts re-loading in windows. After plugging in, if I shutdown the device by pressing power button for 15 seconds, the re-loading in windows stops but after than adb doesn't recognise the device - says error no device
"reloading in windows"? What do you mean? It should be powered down when you plug it in, then when it boots into fb mode, you're ready to adb.
OMAP 4400 is a hard brick. You flashed KFU and now the bootloader is screwed. You will need to look up how to flash the emmc on here.

Hard Brick? Or not?

Here's a longshot as this forum is close to its death, but I was building PA (wanted the old memories) for the Kindle. Fast forward, everything built and it gave me a flashable zip like it should. Upon flashing the zip with TWRP 2.8, I rebooted and now it is just on an infinite loop with the Kindle Fire logo. Not the blue one, but the original one. I am unable to get into anything, not fastboot mode or recovery? Any thoughts or solutions? Thanks!
Edit: I should also mention that the original Kindle Fire logo shows up for a few seconds, then turns off and does it again hence the loop.
When you say you can't get into fastboot or recovery, is that via the device? Have you tried via adb?

ADB is useless at this point - it only works if you're booted into Android or in TWRP and connected to a computer previously authorized for ADB via Android.
OP - did you use a fastboot cable? Also, can you verify the drivers are installed properly? You'll need to disable driver signature enforcement on Windows 8+ before the drivers will successfully install.

A hard brick is generally described as a device that won't do anything at all. Since your device is showing the kindle logo on the screen, there may be hope.
Hold the power button until the screen goes blank, than plug in a fastboot cable. If you can boot into fastboot, then you are not bricked. If you can't get it to fully power off, then you may need to disconnect the battery, which I have no clue how to do since I've never taken apart one of these devices.

If you've got the kindle connected to a computer with working ADB and fastboot, you can also type fastboot -i 0x1949 poweroff to turn it off, if I remember correctly.

Some help I stuck on the 'Kindle Fire' logo bootloop (tate x43z80

Dear specialists from XDA:
I'm from Brazil, and I bought a Kindle Fire HD 7 (MODEL x43z80 'tate') with the last original Fire OS, and the Amazon universe don't have a lot of things in Brazil, so I decided to put a Cyanogenmod based on Marshmallow. My guide is the Tekify Channel, and I got it.
But, after a soft reset, because I want to give a gift to my wife, I have the TWRP bootloop issue.
After a 1 week from search in XDA and a lot of English tutorials in youtube, today I have the kindle in stucked in the 'Kindle Fire' logo bootloop.
So, I search here in XDA wha I have to do, and I stucked.
I don't have a fastboot cable, in Brazil Amazon sold just the basic kindle e-reader, and I want the Kindle Fire good again... :crying:
Someone help me? I try ALL the aplications here, like: KFHD unbrick, Kindle Fire 1st Aid, but I1m stucked in the Kindle Fire logo.
I can't access the ADB or Fastboot, because the computer don't recognize the KFHD, and I can't access the TWRP or any screen, I tried a lot of times the command POWER+VOL DOWN, but I return to the 'Kindle Fire' logo.
Thanks for the help.
J.C.
From powered down condition, press power button, then hold POWER-UP, until blue fire logo appears and continue to hold for a couple of seconds, then release. It should go into TWRP. From there, ADB should work. If not, try powering up while connected to PC with USB cable. Hopefully it will boot into fastboot mode. I use linux because windows has too many problems with drivers.

hi,
i have Kindle Fire HD 7" after some issues i try to flashing, voip all data and delete backup etc, my WTRP V.2.7.8.0 changed to v.2.6.3.1 and stuck in kindle fire logo and not connected to pc or not show storage in my computer.
please help me and restore my kindle fire tate. thanks a lot (i am using Ubuntu 14.04 LTS)
Can you boot into TWRP? You need to update to at least V2.8.7.0. I'm running V3.0.0.0 but I can't find the download link anywhere. If you're in TWRP 2.6.3.1 try going the the boot menu and reboot to bootloader. This should put you in fastboot. Next, connect to PC via USB. Type fastboot devices to see if it's working. Now fastboot flash recovery /(path and filename to TWRP 2.8.7.0) Once you have the newer version installed, remove usb cable and reboot to twrp and make sure mtd is enabled in the mount menu. You sould be able to connect usb cable and drag and drop your chosen ROM and gapps into the internal storage where you can install them with TWRP.

Make sure USB 2.0 or less on PC port. Try a different cable. Try another Android device just to make sure everything works on the computer.

Thanks again to you
Kindle show in my laptop but connect see pics.
Try installing mtp USB many times but not successfully installing in my laptop.
you need a newer version of twrp. If fastboot won't work, I don't know how you can flash a new recovery or bootloader.
The last thing to try would be to update adb and fastboot from Google or the Ubuntu repositories. https://developer.android.com/studio/releases/platform-tools.html
Try: fastboot -i 0x1949 getvar product
Try with root: sudo su
I have never used a fastboot cable. It hasn't been necessary but it may be in your case.
