[Q] Brick Fire HD 7 black screen after root - 7" Kindle Fire HD Q&A, Help & Troubleshooting

I rooted a friends HD 7 unit and loaded the img and twrp for the HD 8.9 by accident. Was told that it was a second gen however found out unit is really 43Z60 which is 1st gen HD 7". Did the following:
adb push stack /data/local/tmp/
adb shell
su
dd if=/data/local/tmp/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1
mount -o remount,rw ext4 /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
mount -o remount,ro ext4 /system
reboot bootloader
Unit OK after reboot to this point. Then did the following:
fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.3.img
fastboot -i 0x1949 flash recovery kfhd8-twrp-2.6.0.0-recovery.img
fastboot -i 0x1949 reboot
After this fastboot reboot the unit is now black and will not give any logo or power on. Tried the 20-30 sec power switch and running fastboot -i 0x1949 getver but no change. Device does not show up in device manager. Read some other posts that purchasing a fastboot cable may be able to recover it. Do you think that will help or am I screwed at this point? Should I try another method of recovery?
PLEASE HELP! Any comments appreciated. Otherwise off to Ebay to buy a used unit!

You completely screwed the device by flashing kfhd8.9 files to a kfhd7

I would try to get a fastboot cable to see if it goes into fastboot. that way you can double check before you purchase another device.

Strange, I thought flashing a bad kernel wasn't a problem, he never flashed his bootloader over so he's got that going for him, but I thought fastboot didn't rely on the kernel as I flashed an incomplete bootimg once and it kicked it into fastboot immediately. I would attempt a fastboot cable but seeing as it never even gets to the bootloader logo, I seriously doubt its going to turn back on, even though I thought the bootloader would have to hand off control to the kernel so Idk. You didn't flash the bootloader correct? Technically its possible to recover from a hard brick but we still need the pin out for the 7" model and it requires some very skilled soldering, i wouldn't have even thought of attempting it until I recently got an st7 bit for my iron.

>>Stunts,
I only did the steps indicated above and nothing else. I ordered a fastboot cable so I am trying that first. What steps do you recommend I follow with the cable if that works?
If that doesn't do it then do you have the procedure for doing the soldering? I am pretty good at soldering stuff.

If fastboot happens to work you can restore with kindle fire first aid or SRT, but the problem is I think you are more likely going to have to go for the soldering method but there is one big big problem with that method, we don't have the contact points mapped out on a 7" kindle HD for the emmc, I would assume at some point kurohyou will gut a 7" HD to map out the points but he hasn't yet. I have no idea how similar the hd7's motherboard is to the 8.9" models, it might be the same contact points, it might not, if it wasn't and the points were there you would probably short something out. If you are wondering why we haven't mapped the points out easily it because in order to do so someone(namely kurohyou) has to get ahold of a hard bricked kindle motherboard and desolder the emmc, once you desolder that you can with the battery disconnected do continuity tests on the motherboard from an emmc pin to a contact somewhere on the board, but chances of being able to put the emmc chip back on aren't that great, unless you get lucky with a toaster oven or have an IR soldering station(very expensive). This was probably a bit more in depth than you wanted but I was bored so I starting writing a lot, anyways hope this inform is informative.

[Q] Unbrick Kindle Fire HD 8.9 without a factory cable?

I made some changes to the build.prop and rebooted, and now it gets stuck at the Kindle Fire boot animation. I can't get it to boot into safe mode either. Is there a way to unbrick or restore it without a factory cable? I can't get it to show up with adb.
If there's no way, I could probably make a factory cable, but it would be nice to fix it without having to do that.

Yes there is a way to get the 8.9 into fastboot so you can restore it without a factory cable, as a factory cable does not work on this device.
Power down the device and unplug
Open a cmd prompt where you have access to the fastboot script from SDK
Enter this command (or any fastboot cmd as long as you include [-i 0x1949]:
Code:
fastboot -i 0x1949 getvar product
It will say "waiting for device"
Plug in the device and it will automatically boot into fastboot.
I have confirmed this works works when the device is in a loop and adb is not recognized. This does not work on the other models, a factory cable is required. Once in fastboot you can flash a backup image. I will be posting an update to the KFHD SRTool in the development section this morning to include 8.9" version

Tried that... The command you said just shows the help list, if I do a different fastboot command it says waiting for device and then the Kindle boots normally and gets stuck at boot animation like usual.

Are you sure you typed that command correctly because the help menu comes up if a command is entered wrong, I just did it and it worked fine. When you enter a fastboot command for this device it has to have the- [-i 0x1949] after fastboot, that is a zero not an O. If that is not done it will boot normally
ie:
fastboot -i 0x1949 [command]
I've posted the update for the 8.9 restore tool in development section
It could be because I have an older version of fastboot. Any chance you could upload the newest version for me?

Here you go:
https://docs.google.com/folder/d/0B4lZEJI5lYeMdzJobG5jSk9QSEk/edit
If you need to restore the system image though, you should just download the KFHD_SRTool from development section for 8.9 and follow the instructions. It has fastboot included in the tool.
I've done the same thing with my kindle fire hd 7 (7.2.2 rooted, no TWRP), now its just stuck on the boot animation.
adb does not recognize the device. I tried using fastboot, (with the normal usb cable), it gets stuck with the '<waiting for device>' message.
The device manager does show the Kindle, but earlier it used to show 2 devices, a kindle and an adb composite
Were you ultimately able to solve this issue?

Turns out, it was a driver issue. Installed the proper Amazon driver, then it was detected by the adb. From there on, I was able to replace the bad build.prop with my backup

My Kindle Fire 8.9" SW v.8.1.4 is completely dark and unresponsive as the result of an unsuccessful attempt to root using KF utility 0.9.6. I suspect results would have been different if I'd had the sense to locate your tool and use it instead. Having downloaded KFHD for v8.1.4, I have tried to get the tool talking with the brick, and see only < waiting for device > eternally. I have charged overnight, held the power button down for >20 sec. to make sure the device was off, then bumped the power button. This should assure that the device is on, but in Amazon's wisdom there are no LEDs to confirm this. Do you have any suggestions for getting the device in a communicative state? I am perfectly willing to open the case. Please forgive the post if this is not the right thread for it, and point me to the right spot if you can.

I have exactly the same problem. This KFU-version seems to be a real KF 8.9"-killer.
My device does not respond to anything, regardless what I tried. Connecting to a PC does not trigger any response. The device is not recognized by the PC in any way. I believe that there is no USB-communication at all. I tried a factory-mode cable and this didn't work, too.
Any help would be appreciated, really!
Thanks and regards

Add another brick to the pile. Fire HD 8.9. Already rooted, OTA defeated, and Google App'd, but wanted the security of FFF just in case. Planned to used KFU 0.9.6 to set fastboot and then push FFF 1.4a once in fastboot. Instead, used KFU 0.9.6 to automatically install FFF. It appeared that KFU pushed FFF and then sent a reboot. The machine never came back to life after that shutdown.
Attempting to get into fastboot results in eternally <waiting for device>
I removed the back - there are no obvious 'fastboot' pads on any of the boards as there is for the HD 7".
Does anyone think that a factory cable would get this thing's attention? edit...apparently not. http://forum.xda-developers.com/showpost.php?p=20380015&postcount=9
edit 2...built a factory cable and tried fastboot, KFHD Recovery tool, KFFirstAide, KFU, and Linux Fire Kit. Nothing can see the device on the other end of the USB cable.
Well...there's always a 'motherboard' swap. Sigh.
Another one bites the dust...but hopefully not
Hi guys,
I tried the KFFirstAide tool to root my Fire 8.9, but after it ran, it just wipes red and then goes to the fastboot screen after powering up. I've used the KFHD SRT tool to replaced the system.img file, but still the same thing happens. Is it possibly because I need to restore the boot.img and recovery.img (which KFFirstAide overwrites) as well? And if so, does someone have a clean copy of those that will work with 8.1.4? Thanks!

anyone have a working link for KFHD_SRT? i can get into TWRP and into fastboot mode, but simply trying to boot results in a black screen after the blue kindlefire logo
Wait don't do it!

I hope you didn't swap motherboards... Like user onemeila stated, you do not need a fastboot cable on the Kindle Fire HD 8.9. Just make sure that before you enter the command "fastboot -i 0x1949 getvar product" that your Kindle is off and plug into the factory cable. Enter the command and wait for the message <wating for device>. Then turn on your kindle and you should boot into fastboot mode. If you see the fastboot screen on your kindle and Jem-PVT-Prod-04 in the command terminal, there is hope. The only problem I encountered is after each command, sometime it won't respond. So you might have to do one command, let it finish it's process. If the next one doesn't work, turn off the kindle enter "fastboot -i 0x1949 getvar product" command. Turn on the kindle and proceed with the next command to restore your kindle.
The way the device is setup, it's very hard to completely ruin the device.
Also read this page for reference by hashcode http://forum.xda-developers.com/showthread.php?t=2128175 and make sure to thank him. He helped me get my device going no problem. The top and bottom of the page should apply to you. If you need additional help let me know.

You are pretty much screwed. Sorry to tell you. You've flashed over the bootloader, the problem is with one that doesn't work. So your device won't even boot into fastboot no matter what you do. There was a way to do it on the original KF by removing the back and grounding the usb boot pad, then you could usbboot cmds to install the bootloader. But I'm not sure if it will work or ever been tested on this device. Good Luck, look on the bright side you can turn it into an extremely thin planter box, that still serves no purpose
well
I didnt read everything carefully but succeded in rooting my KHFD 8.9"
then i tried to install FFF using KFU and then it restarted and i couldnt power it on
well i have tried using FireKit .. but it says waiting for OMAP device..
then i wanted to do the shorting trick !!
i have searched for two days and couldnt find any where the how to USB shorting of KHFD 8.9
please help I am getting frustrated..

[Q] KFHD Boots to Kindle Fire Logo then shuts down. Possible Brick?

Hello all so took it upon myself to try and help my father out with his tablet. Tried the steps outlined in this post http://forum.xda-developers.com/showpost.php?p=45946493&postcount=3004 The unit wasn't on the 7.2.3 bootloader so i proceeded to flash that before following the steps outline in that post. Not the tablet will try to boot but not stay on. Is there a way for me to save it or is it done?
Tried the following:
This relies on you having a working device (as long as it can boot at all, you're good). If you wish to enter fastboot mode to flash system images like new versions of TWRP or restore Amazon OS 7.2.3 if you've got freezing or bootloops, then you need a regular USB cable that came with the device, or any other mini-USB cable that fits the device and the computer. Again, you need to have Android SDK installed before you can use fastboot. Turn the device off, and leave it unplugged. Go to your computer, open command prompt, and type this:
Code:
fastboot -i 0x1949 getvar product
Hit enter, and it should return with <waiting for device>. If it doesn't, your fastboot drivers aren't working. Install Android SDK and go from there. If it does, connect your turned-off Kindle to the computer. Two things will happen: one, the command prompt will show "Tate-xxx-xxx" (something there), and two, your Kindle should reboot into fastboot mode. To exit fastboot mode, after you finished flashing what you needed, type this:
Code:
fastboot -i 0x1949 reboot
If you can fully boot into the ROM, you can use ADB to boot into fastboot, but you must still use the same command above to reboot out of fastboot mode. Then make sure ADB is turned on through settings, connect the device to the computer using a regular USB cable, and type this:
Code:
adb shell su -c "reboot bootloader"
And that's all for the basics! Let's move on to the actual process.

Still nothing the tablet boots to the logo and shuts down. Will i need to purchase one of the fastboot cables or a nexus 7?
If it's a kfhd 7" or kf2, then a fastboot cable is your best bet, the fastboot getvar product command only works on a 8.9" model unless you have 2nd boot loader on the other models.

Damn well that's better then having to pay for a new tablet. I put it on the charger after reading that it may be a charging issue. I know it only trickle charges through USB. It still does the same thing but where the screen would be black behind the kindle fire logo it is green with lines running through it. I will let it charge try again and then buy the cable if anything. Any other thoughts or ideas?
Uh I hope the boot loader isn't damaged too bad, I haven't heard of green lines going through it before, usually if something goes bad with the 2nd bootloader installation process(aka not downgrading first) it results in a red screen. This is probably due to a bad download of the boot loader, that's why it is always key to check the md5sum of the boot loader before you downgrade it.

Lines in the screens, good LCD screen not withstanding, are not good. Normally this is a firmware issue that required Amazon to send a replacement. Let's hope KFFA restores everything for you.

I let it charge overnight and booted it and it is still only booting to the kindle fire logo and shutting down. Luckily the screen is black now rather than the green I mentioned. So is my best course of action the fast boot cable and then KFFA? I will try the fastboot commands again when i get home. Is KFFA only going to help me in the sense of restoring the files or will it potentially help me with the fastboot process as well? The above method that I used with the fireflash 11 is that proper or should i be doing it some other way?
I personally think the fire flash method is the easiest, some people brick though because they don't follow the instructions properly, I don't think this was the case with you though. That kindle is more than likely not going to go into fastboot with commands, that typically is a 8.9" thing unless you have a successful flash of 2nd bootloader. I know kffa restores the system partition and recovery and boot, but I am unaware if it flashes the boot loader, and I am pretty sure you definitely need to reflash the bootloader since it had lines through it.

You must have a fastboot factory cord, not a regular USB. Watch this video to make sure you have your ADB driver set up right http://www.youtube.com/watch?v=oaNM-lt_aHw Use KFFA to restore to 7.2.3. Choose that option as Hashcode has a 7.2.3 boot.img that will match the firmware you will be using, reducing the chance or bootlooping a great deal.

[Q] FASTBOOT Issues - Not booting into

I have Kindle Fire HD 7 - 11.3.1.0
I am an adb users. I know how to use it. If that helps. My problem is that I cannot get the device to boot into fastboot. I run the command adb devices and it sees my device.. I reboot it, shell, etc. But when I run the "fastboot -i 0x1949 getvar product" command it stays on wait for device. I am using the factory cable that came with the device. It is new. I have run out of ideas... I start with a powered off device (adb is enabled in the settings).. I run the command on the command line.. its now sitting on waiting for device....I plug in the cable .. it powers up.. but just boots. I was able to root the device.. but will NOT boot to fast boot...
Please let me know if I am missing something..
Thanks

If its rooted run this
Code:
adb shell "su -c 'reboot bootloader'"
What exactly are you trying to achieve with fastboot, that's a 2013 HD, we only have root access so I don't know what you want to use fastboot for.

I want to flash it back to the earlier version .. is this not possible.. it seems to be...reading that it needs to be reverted to 7.3 or something..

Woooo, slow down. You have the 2013 Kindle Fire HD 7 and there are no exploit for the bootloader yet. You're gonna brick your tablet. That exploit is for the 2012 Kindle Fire HD 7 only. Stop now and know there is only root available for your tablet at the moment.
Hi.
I've got the same problem - but got 2012 device ( no. D059, camera on left (or right/down/up if you like ) side of screen )
I use typical usb cable, got root acces, adb see my device. But when I plug after typing "fastboot -i 0x1949 getvar product" its normally booted up to system
any advices?

Woa there don't attempt that. 2013 kindle fire hd's aren't supposed to run a 7.x.x os, that's the version used on the previous years, your is supposed to be 11.x.x.

anybody?
I look for factory cable, but in Poland it is unavailable anywhere is there possibility to do something with normal usb cable?
"adb reboot bootloader", also what are you attempting to do with fastboot, just wanna make sure you aren't trying to downgrade to an os not meant for your device (aka anything besides 11.x.x is not meant for your device and will brick it).

I want to flash custom rom.
Read my first post in this thread - my Kindle is 2012 device.
But problem is same that adkg12's so I post here, altough write new one
Eh I would just use the fireflash method as it doesn't require fastboot access, though if you don't see the checkbox next to the red text and leave it unchecked your kindle will have a red screen that only a fastboot cable can fix. Might be less dangerous for you to just use the method you are using then, as long as you check everything's md5sum then its a lot safer for you since you can't get your bands on a fastboot cable.

First thing is to download the SDK package and set the environment up. Here is a great video tutorial https://www.youtube.com/watch?v=oaNM-lt_aHw This will allow you to use fastboot command which is what you will do to push the images you need onto the bootloader.
To make sure your computer issue fastboot commands, open up a comand prompt as an administrator and type "fastboot -i 0x1949 getvar product" with no quotes and it should return Tate-xxx-xxx. If you don't get that response, do not move forward.
Once your at this point, download this tool http://forum.xda-developers.com/showthread.php?t=1951254 and either use it per the instructions or extract the files and CD from inside the folder and manually flash the 3 images via fastboot issuing these commands
fastboot -i 0x1949 flash boot "image name here" include .img at end
fastboot -i 0x1949 flash recovery "recovery name here" include .img at end
fastboot -i 0x1949 flash system "system image name here" include .img at end
Now give some time as the system image is quite large
when done, type fastboot -i 0x1949 reboot
Profit

Never, i get bootloop before turning.
I'll be honest I was a complete book at this first I couldn't use fast boot to save my life what so ever, I found a way where I didn't need to use fast boot commands and it was noob proof, quick question do you by any chance have a fast boot cable?
If so I'll be able to help you save your Kindle Fire

I don't have a fastboot-factory cable beacause the shipping time is very long and i'm worried about the customs.
Anyone knows a place that send this cable in europe quickly?
EDIT: Jserrano56, your method requires a factory cable, too?
@HylianHero
Europe...? Dude I got mine from eBay and it was here in 3 days, you'll need one no matter what, without it you have a brick, a paper weight, it's practically useless
Long shot, but maybe a final resort without a fastboot cable?

Kindle Fire 2 7" Stock Restore

Guide not available any more
Restoring from CM
In case i wanna restore to the original FireOS, is it also possible to boot into fastboot via "adb reboot recovery" and follow your instuctions? (In case of no fastboot cable and not beeing in a bootloop)

I have had some problems using ADB fastboot before but on the other hand I have successfully carried out this restore using it too. As long as you flash the correct files to the correct partitions then you will be able to restore still if something goes wrong. The only thing that can go a bit screwy is after flashing boot and recovery, a fastboot -i 0x1949 -w should be carried out before flashing the system file. You do not need to fastboot -i 0x1949 -w AFTER flashing system.img in this case.
Cool, so i should be on the safe side when i restore to stock
Going to try it out later and give you a feedback!

Sorry for late feedback, was too busy last weeks.. weird thing, can get the kindle to reboot into fasstboot ?!
Tried it via shell on the Kindle itself (su, then reboot bootloader), tried it vie adb (adb reboot bootloader) also i also tried it with a root shel opened via adb and then reboot bootloader).
Seems like reboot command sets bootmode always to 7, at least thats the output of the shell regardless which option i give reboot

Have you tried "adb reboot fastboot" rather than "bootloader"?

Writing new vars to temp area
You must reboot before new values will take effect

Ok, the reason this is not working for you is I think your Kindle is not currently rooted, which is why the bootloader does not kick into fastboot.
There is a post to access fastboot via adb but I think it is for KF 1st Gen so I would not personally try this. Failing all this, why not have a go at making your own fastboot cable? I have made several now and it really is easy and it can save you a lot of bother if something goes drastically wrong?
Let me know how you get on

Strip down a micro usb cable and make your own factory cable, I promise you it will end all your troubles
Hello I am trying to restore my Kindle Fire 2 using your instructions. I have a factory cable and boots up to fastboot just fine. All goes well until I get to "fastboot –i 0x1949 –w" and receive this error message:
erasing 'userdata'...
OKAY [183.180s]
formatting 'userdata' partition...
Erase successful, but not automatically formatting.
File system type not supported.
OKAY [ 0.120s]
erasing 'cache'...
OKAY [ 70.971s]
formatting 'cache' partition...
Erase successful, but not automatically formatting.
File system type not supported.
OKAY [ 0.116s]
finished. total time: 254.386s
Then when I reboot the device I come up to the red triangle logo and do a restore to factory settings but now the kindle is stuck on a bootloop.
I hope someone can help as I have tried all sorts of things to try and get the device to work.
I got stuck with your instructions, but in the end it was something simple.
I had adb drivers setup etc, a proper fastboot cable which works perfectly, but every time I tried to send any of the commands it sat there "waiting for device".
What I was doing was copying your commands from the guide, from Win 7 Wordpad.
Once I manually typed the commands they worked perfectly, even though it looked exactly the same in the command prompt!
I tried this on Ubuntu 14.10 and two Win 7 PC's, and they all did the same thing. As soon as I manually typed the commands everything worked.:good:
that write up is spot on. thanks.

Edit - I have edited the instructions file as the fastboot -i 0x1949 -w command needs to be done BEFORE flashing the system.img file otherwise you can get stuck in a boot loop in rare cases. This should now work 100%.
Ok, after weeks of reading these forums I found that because of the sheer volume of help available for people with faulty or bricked Kindle Fires, it can be a little overwhelming for someone to attempt to repair their device and in some cases they can take the wrong course of action and end up making matters worse.
I thought I would write a guide for a specific common problem which is a Kindle Fire 2 stuck in a boot loop. The boot loop being that the Kindle Fire logo flashes on the screen, stays for a number of seconds and then the Kindle restarts and the same thing happens over and over. Now I know there are other similar threads around and even some programs that have automated utilities to do this but I found that most of them were not successful and I ended up doing this my way anyway. This guide is also assuming that you can enter Fastboot mode on your device.
I have attached all files needed for this guide so you don't have to go looking over the internet and clicking lots of links to get what you need.
Download the following files and follow the instructions in the word document.
