[Q] KF Possibly Bricked

Just got a new KF today and tried loading Go Launcher EX. Got to the point where I rebooted the KF and told it to always boot to GO Launcher..... BIG MISTAKE... something had gone wrong in the go launcher install and Not I have a pretty Kindle Fire Logo on my screen that will not go away.
I have downloaded KFU and Installed the drivers. With my KF on and plugged into usb my device manager shows. "Android ADB Device" which if i read correctly is what it should show.
But inside KFU it does not seem to connect to the device.
Is there something i have missed or is it truly a brick ...

I tried that ... Uninstalled device (made sure to remove driver) refresh device manager.. update drivers on kindle device... Then tried KFU
All I keep getting is waiting on device...
On the main screen it says:
ADB Status: Offline
Boot Status: Unknown
When I go into the Bootmode Menu and select 1 it sits on a screen saying waiting on device.
This is pretty much where i have been stuck at all day ...

Power your kindle off by holding the power button for like 30 seconds its very likey that adb will not detect your kindle it cannot while its in fastboot But first try this shift plus right click on the tools folder in kindle fire utility select open command window here power your kindle off and enter the command Fastboot getvar product (hit enter)Plug your kindle in it will power on in fastboot If you get the response product: kindle then we can move on.
if you get the response product: kindle Type fastboot oem idme bootmode 4000 (hit enter)fastboot reboot (hit enter)
Nothing.?then Then next time try fastboot -i 0x1949 getvar product (hit enter) when it says <waiting for device> plug in your powered off device if it says product: kindle type fastboot -i 0x1949 oem idme bootmode 4000 (hit enter)fastboot -i 0x1949 reboot(hit enter)

Fastboot getvar product
fastboot -i 0x1949 getvar product

I tried both of these. Each time i unplugged the KF, held power for 30 secs(using a timer),typed command then hit enter, then plugged in KF.
both times it powered on and went to the Kindle Fire logo and the command window just said waiting on device. A side note is that during power on but before windows beeped as if it had recognized the device the KF logo blinked a few times.

Don't unplug it.
I've found with mine, whenever I'm stuck in fastboot I do the following:
1. LEAVE THE KF PLUGGED INTO THE COMPUTER AT ALL TIMES!
2. Uninstall all instances of the Android Device in Device Manager.
3. Power off KF by holding the power button for NO LESS than 30 seconds. Even when it looks off, keep holding it and count to 30. (keep plugged in)
4. Power on the KF by simply clicking the power button once. (still plugged in)
5. Once the KF is back at fastboot, the computer should automatically install the drivers from the KFU folder, if not then manually point it there.
6. Open KFU and start run.bat
7. At the menu, regardless of device status (mine says offline/unknown when in fastboot mode), press 1, enter, 1, enter.

so are you suggesting i do the command line stuff?
EDIT.... any way i cut it im getting the same Kindle Fire screen ...

one I used this -i 0x1949 one I didnt because sometimes it doesnt matter but lelandfried is suggesting to try to use kfu to reset your bootmode which is logical and keep working with your drivers which also makes 100% sense keep trying you could get lucky and something will work its windows darn drivers that are killing you another option is this http://forum.xda-developers.com/showthread.php?t=1670405 then you wont be messing with the drivers anymore add sudo to the front of all your fastboot commands.

If I have ubuntu running on a VM can I do this through there? I have mixed success using usb devices

whoops sorry soupmagnet will know if it will run on a vm ask him he can give you the best advice

No problem. Im going to give it a shot... I have done everything i can think of to get the right drivers on here in windows. As best as I can tell from the chart on this thread http://forum.xda-developers.com/showpost.php?p=23747671&postcount=2
I have the ADB driver loaded for Recovery,Stock SW or ROM (USB Debog On)
I think I will try the ubuntu thing for a bit .... Frustrating .. very frustrating

I gave ubuntu VM a shot. I was able to connect to the device via usb in the VMWare console then i tried to run the two commands given earlier in this thread ... but i was never able to get anything but a <waiting for device> message in the terminal window.
Hopefully someone can give me some new guidance. Or show me where im going wrong so far. I feel like its something dumb that im missing ...

did you use sudo before all your commands and plug in your prepowered off kindle in when it says waiting for device?

Soupmagnet said he had problems getting the KF to work with VMWare in fastboot mode. YMMV. I use Parallels Desktop and have no problems with it.
The most telling thing you said in this thread...

If the logo "blinked" a few times, then it's not in fastboot mode. It is most likely past the bootloader stage, loaded the boot partition and trying to start up the system. At this point, your best hope is to send it some adb commands to get the KF into fastboot or recovery, but it might not be far enough along in the process to accept adb commands either.
Read the following post about fastboot mode...
http://forum.xda-developers.com/showthread.php?t=1668159
Most people in your situation end up buying a factory cable.

Okay. thank you to everyone for the help so far. From within Ubuntu I was able to use this guide http://forum.xda-developers.com/showthread.php?t=1414832 to get into fast boot mode. From there I installed TWRP Recovery then rebooted into recovery mode. Then I installed FFF, Rebooted into recovery mode and reset to factory.
When I rebooted I got the FFF boot screen and let it boot like normal to a factory reset KF.
Again thank you all for your help .

I'm glad you got it going just make sure you do all the right things if you start flashing roms don't be afraid to ask questions its better than getting messed up again always make backups and do proper wipes just don't wipe your SD card or let your battery die good luck

I dunno how to do adb thru Ubuntu, even though I have it on my desktop. I do all my adb stuff through my Windows laptop.
Glad to hear you got it going. I'm bookmarking this thread for the Ubuntu links and info, Thanks!

[HELP] KFHD 8.9 Red Screen

Hi all,
First off, this is my first post :victory: and I need some help.
Last night I used this thread to successfully get root access on my Kindle Fire HD 8.9".
Then, wanting to install CyanogenMod 10.1 on the Kindle, I tried to install the second bootloader and TWRP Recovery. At this point, the Kindle began to reboot. When it turned on, the Kindle Fire logo appeared, shined a few times, then blank red covered the screen.
I can turn on/turn off the Kindle, but all I see is this red screen. Anything I can do?
I've looked at factory cables, hopefully there are some things I can try before I buy that...?

A factory cable won't work on the 8.9
Disconnect the USB cable
Turn the device completely off (hold power button for 10 seconds)
Enter: fastboot -i 0x1949 getvar product
Reconnect the USB cable
As the device powers up, if your fastboot drivers are working properly, the device should boot into fastboot mode. Use it to restore your saved partition images.

Thanks for reply
Hi soupmagnet,
Where do I enter the command "fastboot -i 0x1949 getvar product"?
In command prompt on the computer?
EDIT: Self-explanatory It worked perfectly - thanks!

HAVING SAME PROBLEM KFHD 8.9 2nd Gen RED BOOT.
I have the same problem. Can boot into fast mode with KFFA, but restoring stock settings seem to be Impossible. I have tried to restore with ADB, ADB (Fastboot), KFFA, and KF SRT. No matter what red boot screen will not go away and device can only fastboot. Any help?

Red screen is also considered a hard brick. Sometimes restore does not work.

Same happened here
Today I rooted my kindle fire 2nd gen10.4.8 using vroot I also installed a boot loader that as soon as I tried downloading shut my kindle fire down and when I tried unsuccessfully to turn it back on the red kindle fire symbol came for a second and then the careen was red

http://forum.xda-developers.com/showthread.php?p=46154263 follow this and you should all be away from that red screen

same here but worse
My kindle is rooted and when i flahsed a recovery it asked if i wanted to boot into recovery after i said yes then when it booted the kindle fire logo appeared for about 1 second then a red screen slid in from the side now it wont boot into recovery fastboot or normal mode and i have reinstalled kindle drivers several times as well as fastboot.exe and also adb.exe and nothing works the computer sees it for 3 seconds if i hold power volume down but then it goes to red screen

You need to run this on the computer: fastboot -i 0x1949 getvar product
Once it says waiting for device, plug the kindle in while it is off, if the bootloader isn't too damaged it should kick into fastboot. Hopefully you also installed the fastboot drivers previously or your best bet might be a Linux live distro like Ubuntu.

fastboot doesn't recognize if there is a way to fix this or a way to keep the kindle connected for more then 3 seconds i would appreciate it

What does the kindle show up as for those 3 seconds? Because usually it shows up as a jem device (without the driver installed) or a adb device (with fastboot drivers installed) and in those 3 seconds that command gets it to go into fastboot mode so you can fix it. All that needs doing is the bootimg needs to be flashed or erased and fastboot should be more cooperative.

I ran the fastboot command like you said, and got my kindle to go into fastboot but i have no idea what to do next.
should i run certain files?if so please tell me where and how?

Use kindle fire first aid or system restore tool for the rest once it is in fastboot mode or flash a backup of your boot image with "fastboot -i 0x949 flash boot boot.img", that should fix a red screen/bad loop scenario where fastboot is not working well, etc.

thats the problem

i cant tell what it shows up as because by the time it shows up in the device manager the kindle disconnects
how do i flash a boot.img if the kindle is only connected for 3 seconds and fastboot isn't working

A ubuntu live os probably would do the trick

[Q] Fastboot looped Kindle, unresponsive to fastboot commands

Hey guys,
After trying for the past two days and a lot of hours to get a good enough grasp to undo a hasty attempt at rooting my kindle, I've decided to come to you with a request for help!
It all started when I installed the amazon usb drivers for kindle fire and then loaded up KFU. It read that my kindle was in boot mode 4000 (normal boot mode) and I told it to root my device. It seemed to be working fine, until all the sudden, it froze as it was trying to load TWRP onto my kindle. AFter waiting some amount of time, I finally just cancelled the job and tried to reset my kindle.
Ever since my kindle is stuck at the stock loading screen. No FFF, just the regular kindle fire logo and it never dims in light, which is a clear indication that it is in fastboot, and isn't going anywhere. Well at that point, my windows drivers failed me and ceased to recognize my kindle. Well, I tried everything to get windows to recognize the device but it failed. I even tried creating a bootable ubuntu partition and using the linux drivers with firekit. It didn't really work as well as I'd have liked.
Recently, I used my roommate's macbook and fastboot to try and see if there was any hope for communicating with my kindle.
The "./fastboot -i 0x1949 getvar products" command returned "product:kindle" suggesting that the macbook recognized my kindle.
YAYY!
but when i tried to reset the bootmode to 4000, it just sat there with three dots and did nothing. i tried to flash TWRP again, same thing. Each time i would cancel the job and then when i went back to try and recognize my kindle, even the macbook had lost it.
Ideas?

Hold your power button to shut it off, then start it up again. Does the display stay brightly lit?

[Q] KF stuck at "Kindle Fire" screen, details inside, pls help?

So here's what happened.
About a year ago, I rooted my Kindle and flashed CM 10.1. Everything worked out great.
Fast forward to a few days ago, I thought it'd be cool to give the KF an update. Total mistake. I wanted to flash CM 11, but figured it'd be important to install the latest version of TWRP as well. Before I knew it, my Kindle Fire was bricked. In the process of updating TWRP, I downloaded and flashed the most recent img file (using Flashify), and after the device rebooted automatically, it wouldn't move past the silver/orange "Kindle Fire" screen. I've since tried a number of things, including powering the device on and off, and holding the volume up button to boot into TWRP, but nothing seems to work. I always end up getting stuck at the same screen.
I've also tried using Kindle Fire Unbrick Utility, but I get a "device not found" message. My computer makes a noise, as if to recognize the KF when it powers on, but within seconds, loses communication.
Am I screwed?

Can you get into fastboot? Did you restore your backup?

Don't worry you must have flashed TWRP for the wrong kindle generation.
Connect your kindle to your pc with the normal cable that is provided with your kindle. Now turn your kindle off and type the following in your cmd
fastboot -i 0x1949 getvar product
now it should show
< waiting for device >
then turn on your device
you should be in fastboot now.

I had a feeling that must've been the case.
I followed your directions, but can't get past the "<waiting for device> message in CMD. Turning the kindle on or off doesn't seem to make a difference. Am I doing something wrong? Are there other alternatives?

Did you follow the steps in the right order
Turn of Kindle
connect the wire
type command
when waiting for device is shown then only turn on your kindle

I have a similar problem. I try to give the "fastboot -i 0x1949 getvar product" in windows cmd but it just gves an error. Do I need to install something to fix this

My guess is you don't have the right drivers installed. You have to install the driver while the device is attempting fastboot. If you have the device manager up you'll see it flash for a second when it boots. Right click when it flashes and install the driver.

Kindle 8.9 8.5.1 Brick using Flash fire now stuck in bootloop

When you used Fireflash, did you get TWRP and second bootloader installed? If you did, power your device off, then power back on. When you see the gold Kindle Fire logo, hold the volume up button until the logo turns blue, keep holding for 3 more seconds, then release and you should boot into TWRP. From there should be able to connect to computer and transfer files using ADB if needed.

I belive i did not. Everytime i do your method it just show the screen on but just black.
I even have a factory cable to fastboot it and it also dosent work /:

USB Drivers
You just need to change the drivers on windows to get it detected properly and access to fastboot
I posted a quick how to here : http://forum.xda-developers.com/showpost.php?p=59900685&postcount=4

Install Android SDK, if you have not already.
Put the kindle in fastboot mode.
Download The Twrp files for kindle fire hd.
Flash The Files
Reboot Into Recovery
Try to see if you can boot into your os
If not, use adb to push a rom into your kindle.
Flash it
You should be good.
