[Q] Need Help With Fastboot - 7" Kindle Fire HD Q&A, Help & Troubleshooting

I am trying to install a second bootloader on my Kindle Fire HD in order to install the Kinology ROM. I am using these instructions: http://forum.xda-developers.com/showthread.php?t=2128848. On the 5th step, it requires me to be in fastboot mode. Do I need a special cable for this? I tried doing as the post said with the charging cable my Kindle came with, and instead of starting in fastboot mode, it boots to the stock OS. What am I doing wrong? Thanks.

To reboot your device into fastboot mode you need to enter this command in CMD wherever you have access to adb
adb shell su -c "reboot bootloader"
Then continue with step 5
and make sure you transfer kinology files to your kindle before you proceed so you can flash it right after you flash TWRP.
but note that if something goes wrong and you find yourself in a bootloop, then this command will not work since adb only works when the OS boots, and you WILL need a fastboot cable to get out, This is a special cable that can be made by making a simple modification to any micro USB cable like the one that came with the device, Believe me you will need one sooner or later.

[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

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!

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

A store demo Kindle Fire HD unit, how to root it and what ROM to use?

I am attempting to purchase one off eBay now and was wondering how I go about making it a real Kindle Fire HD. I have purchased two original Kindle Fire Demo Units off eBay, rooted and tried a variety of ROMs and really enjoy them. I was wondering how I go about rooted a demo unit Kindle Fire HD and what ROM I should put on it?

i brought my kindle fire hd off ebay as a store demo unit, the demo software is locked so you cant access the settings menu and adb debug is not enabled,
what i done to over come this is purchase a fastboot cable, when my cable came i power the kindle off plug the fastboot cable in and the device will turn on and be in fastboot mode, it will also say fastboot on the screen, install the drivers and then

No fastboot cable needed once rooted.
You don't necessarily have to buy a fastboot cable. Its far simpler to root your kindle fire hd:
here: http://forum.xda-developers.com/showthread.php?t=2069117
To enter fastboot mode once rooted you open an ADB command prompt window and type "adb reboot bootloader".
To exit fastboot type "fastboot -i 0x1949 reboot"
Now you'd want to install Hashcode's 2nd bootloader and TWRP to flash roms.
Follow the instructions here: http://http://forum.xda-developers.com/showthread.php?t=2128848
You can download the stock kindle fire hd 7.3.1 rom and flash with twrp and the wait for a proper CM10.1 release which is due very soon.
EDIT: You can also use KFFirstAide to boot into fastboot mode: http://forum.xda-developers.com/showthread.php?t=2096888

So I tried your method but my Kindle wont boot into fastboot. It will turn on when i plug it into my PC with the cable but just continues with the demo stuff. Should i try and get a new cable? I have the ADB drivers installed
You have to use a fastboot cord. This is a factory cord not the standard USB cord. You can make one of buy on for 10 buck or so off eBay.
First, you have to completely power down your KFHD. Hold the power button down for 20 seconds if nothing else. Now connect the KFHD 7 to the PC with the fastboot cord. You should see the word fastboot light up on your screen in just a few seconds.
Now follow the instructions provided in your quote. You can also try Kindle Fire FirstAide. The instructions provided are solid though.

For the Faint of Heart
If you're feeling really adventurous and know how to solder, you could try this. I may end up doing this as well, as I bricked my own KFHD and don't wanna drop $13 for a fastboot cable, and can't get the head off my spare micro-USB cable.
Buying demo units is nice, because you can buy the Kindle for less than half the price, put it into fastboot, and have a normal KFHD.
As for which ROM to use, I would go with @Hashcode's CM10.2. But that's just my suggestion. If you want to still have all of Amazon's media services, such as Prime Video and the Kindle Fire reading app, you can use Kinology.
So my fastboot cable will cause my Kindle to turn on when its plugged into a computer but it doesn't go into fastboot mode. Do I need special drivers on my computer for this to work? I tried it without any software on my computer and with ADB + Kidnle drivers and neither works. When I plug the cable into my Droid 4 and my computer it boots my phone into some sort of special mode, doesn't specifically say fastmode though. Do I need a new cable? Or did I buy an lemon of demo unit lol. Thanks
Edit: I'd like to add that i have the 8.9 version if it makes any difference...
Fastboot cables don't work on 8.9” models, those are much simpler to get into fastboot, at least from my standpoint, you basically just open a command prompt up and CD into he folder with fastboot and run "fastboot -i 0x1949 getvar product" and then after it says waiting for device you plug the kindle in while powered off with a normal cable. You might have to install the fastboot drivers though and that's kinda tricky because the device briefly appears as a fastboot device in the device manager when it first turns on and that's when you would have to update the drivers so it can communicate and send that command so it pops into fastboot. Probably is easier in my opinion to do it from an Ubuntu live CD after installing the fastboot command from the repos on13.10, but i only suggest that if you have driver issues.

[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.
Sent from my Amazon Kindle Fire HD running CM10.1 Tablet UI using xda-developers app
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.

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?

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.

If your going to use FireFlash, you can go to seokhun's thread and read uo on flashing the 2nd bootloader / TWRP http://forum.xda-developers.com/showthread.php?t=2271909
Some great info about this on Opemsystem's thread as well. http://forum.xda-developers.com/showthread.php?t=2347170
Hashcode's thread has the files you need to flash. If you choose 7.2.3, use boot.img 7.2.3 located right below step 4 of Hascodes thread. Not number 4 of step 2, but right below step 4 and the TWRP 2.6.1.0 in his original post. http://forum.xda-developers.com/showthread.php?t=2128848

Kindle Fire HD7 red screen

So I was trying to install TWRP to my Kindle Fire HD7. I had successfully rooted and was using FireFlash to flash the bootloader.
When I pressed boot to recovery the device rebooted showed the kindle logo and then a red screen.
I tried making a fastboot cable but could not get the device to show up in ADB devices. Am I totally boned?
I have links to the directions I followed and a gif of the logo and red screen but I cannot post them since I'm new.
I had this issue also, I just made a fastboot cable, plugged it in and flashed stock files, I then rerooted, installed TWRP, 2ND bootloader, then CM11, finally with PAC-rom.

I can can agree with wire55. Have to have a fastboot cable to fix this. Reflashed stock then created my own personal port ROM.

I made a fastboot (by jumping pin 1 and 4 on a microusb) cable but it shows the device as disconnected in Device Manager.
Here is what it looks like when I turn it on i.imgur.com/TSUHsjW.gif
you dont use adb commands with fastboot mode, you use fastboot commands with fastboot mode. Try "fastboot -i 0x1949 getvar product" and see if it reports back. If it does all you will need to do is flash the older bootloader for your device first(check the md5sum plz so you don't hard brick), then restore with kffa or srt. Fireflash method should work fine now for sure once you have flashed the older bootloader.
concerning rdwidam
It says <waiting for device>
I will try again tomorrow, my friend is bringing over a fastboot cable that we know is working.
I'll report back if there is progress. Thanks.

ok that's good, if the command still doesn't respond after it says fastboot mode on the screen, then go to the device manager and look for a device with a yellow triangle next to it, once you find it download my drivers in my signature, extract them somewhere, and right click the device and hit update drivers, point it to where you extracted mine and let it install. If you are on windows 8 you will have to disable driver signature enforcement first.
OK, I got a fastboot cable but still no luck. Nothing shows up in device manager and no response to fastboot commands. I think I'm going to throw my self on the mercy of Amazon.

So the fastboot cable isn't throwing it into fastboot mode, it is staying at a red screen? You are positive the fastboot cable is a fastboot cable? And i have to ask this even though its stupid but you are positive it was a kindle fire hd 7 and not an 8.9"? The fastboot cables don't work on 8.9" models is why i'm asking, those will go into fastboot with the command i mentioned but its slightly more complicated than that, the device would show up for a brief moment then disappear when turned on.
It is possible our fastboot cable is not working. I will try another one today. I measured the kindle and the view-able screen is 7 inches diagonally, while the whole body including the bezel is 9 inches.

Ok, success! I got out my soldering iron and made a working fastboot cable. Now my kindle turns on and shows a fastboot logo on screen, and I have a device called Tate-PVT-08 in Device Manager. So I installed the android drivers to allow me to use fastboot commands. Then I used KFHD_SRT tools to restore the Recovery and Factory image.
Thank you everyone for all your help and knowledge. I was freaking out a bit, but all is well.

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.
