I bricked my KF GOOOOD this time

I have had a Kindle Fire since they day they came out. I immediately disliked the stock Rom so I ran the kindle fire utility and installed Fire Fire Fire and TWRP, rooted it, and installed CM7 Rom which has been working great. Transferred files and programs between my PC and Kindle with no issue for months. Now with all the ICS roms available and working I decided to try and upgrade to one of those and thats when everything went wrong. Its in a bootloop and the triangle appears, fades, lights up again and immediately boots to TWRP. I have flashed the entire kindle using TWRP trying to get everything off of it. Upon plugging it into my PC BRIEFLY when the triangle logo pops up I get a "USB device not recognized" on my PC. I have tried using KFUtility to reinstall drivers, tried uninstalling n reinstalling drivers but the same thing happens. I cannot use TWRP to mount at all, nothing happens. Kindle Fire UTility keeps saying adb offline, CMD adb devices also results in 0 devices found. I have tried putting it on normal boot using both ADB and KFUtility and it says "wait for device" and nothing ever happens. Any idea? Not even sure if I have a rom installed on my kindle anymore but my PC wontread it so I cannot push another image to it. Got a plane trip on Saturday and would love to have this working to kill the bordom lol. Any advise would be greatly appreciated.

It sounds like your bootmode is set to recovery. An easy way to fix this is download FFF1.4 to your computer and use the mount function in recovery to place it on your sdcard.
Flash it in recovery as you would a rom except don't wipe anything. When you reboot, hold the power button like you're trying to enter recovery and you'll be given the option to reset the bootmode.

Thank you so much for your advice but there in lies the problem. Inside the recovery console i choose to mount it and nothing happens. My PC will not let me access the kindle in anyway at all, either mounting the SD Card or via ADB/KFUtility.

Generally, the only thing that would prevent adb/kfu from communicating with the device is the drivers. Make sure they're installed properly. You may have to uninstall them (delete if applicable) and reinstall them.
Follow the instructions in this guide to install and verify your drivers.

K heres the latest (we r making progress!)
I got my device to be detected by my PC and used KFutility to change it to normal boot. Now instead of booting into recovery everytime it boots normally.... to a black screen (guessing my rom is shot or I deleted it while playing with it). The issue is the ONLY time my PC recognizes my kindle is for a .5 second period when i first turn my KF on and the yellow triangle appears. I can use this window to change it to normal bootmode, reinstall TeamWin, stuff like that, but i cannot mount it so I can transfer or adb so I can push. You can watch device manager and it'll pop up ADB android phone or whatever it should but poof, a second later gone.

Get your device drivers working so you can use adb. Follow the instructions in the post below...
http://forum.xda-developers.com/showpost.php?p=26144447

That is excellent advice and I wish it would work but I cannot pull up ADB once in TeamWin. Keeps saying no devices. As i said my PC detects it and ADB will detect it for .5 seconds on the orange triangle. Once the orange triangle disappears and it either boots to blackness or boots to TeamWin ADB stops recognizing my device. But I will play around with your suggestions once I get off work and let you know what i find out. Thanks again for everyones support.

Frozen screen during rooting
Hi,
I am new to the forum. I have a kF screen stuck (where it says 'kindle fire') while I was trying to root it. I tried hard reset, charging for half hour, calling AMAZON...nothing works. The screen goes off if I hold it for 20 seconds but when I put it back on same thing. I was trying to root it with 'fastboot (?). Is there anything at all I can do? Thanks.

KF stuck at Kindle Fire white/blue logo; tried a few ways including Linux

Hi All.
I’ve rooted my Kindle device successfully before (during v6.2 – have the driver installed from this and cable worked successfully )
Now with the 6.3.1, I used the KFU v0.9.6 to do it – option 2 ‘Install Permanent Root with Superuser’
Followed the instructions as per http://forum.xda-developers.com/showthread.php?t=1399889
- On my XP machine, it detected my Kindle initially but it stopped and my Kindle Fire was showing the stock welcome screen but kept on rebooting.
- Then I tried on a Win 7 machine and ran option 2 again – it did something and now my Kindle is stuck on the FFF screen (Kindle Fire logo in blue and white – v1.4a).
- Now when I run ‘ran.bat’, pc it shows ‘waiting for device’
- The FFF screen was blinking initially but now it’s permanently on.
- I can off my Kindle by pressing the on button for about 20 seconds and when I connect my Kindle in the off state to the pc, it turns on and remain on the FFF screen
1. Installing the driver
So I figured the above is due to the driver.
- However, the Kindle is not appearing in the Device Manager with a yellow ! – hence can’t manually install the drivers.
- Tried install_drivers.bat – it says ‘Google, Inc. (WinUSB)…..Install failed (Unsigned)’
​- I ensured that the ‘Driver Signing Options’ is set to ‘Ignore – Install the software and don’t ask for my approval’ and ‘Make this action the system default’.
- So next, I tried to force my XP to install the drivers (Kindle unplugged), by using ‘Add Hardware’ and installing drivers from c:\kfu\drivers –
​- Installed all 3 drivers – Android ADB Interface, Android Bootloader Interface & Android Composite ADB Interface.
​- Received this message at the end – ‘The software for this device is now installed, but may not work correctly. The device cannot start. (Code 10)’
​- But when I plugged in my Kindle and run KFU it still says ‘waiting for device’.
I tried the above steps with:-
- 3 XP machines and 1 Win 7, and
- on different USB ports (tried both USB 2.0 and 3.0)
- and tried using 4 different usb cables
- Same results ‘waiting for device’
- One exception though – for the Win 7 machine – when I ‘install_drivers.bat’, it says ‘Google, Inc. (WinUSB) ….Ready to use’ – but still shows ‘waiting for device’, when running KFU.
2. Delete old drivers
Followed this (http://forum.xda-developers.com/showthread.php?t=1459116) to uninstall the drivers (including the Microsoft support page).
- But XP and Win 7 still did not detect the Kindle in ‘Device Manager’
- Tried to force install the 3 drivers again and still ‘waiting for device’
Additionally tried to download the Google Usb driver from Android SDK - same issue - no yellow !
And tried to connect via 'c:\KindleAdb\adb devices' (learned from the previous root exercise) - no devices appears.
3. Kindle Fire Unbrick Utility
Tried this next - http://forum.xda-developers.com/showthread.php?t=1428428
Tried the many options available. When it is executed, its says ‘error’, despite saying Kindle unbricked at the end.
4. Firekit LiveUSB repair kit 1.1
Finally decided to use the Linux method (http://forum.xda-developers.com/showthread.php?t=1430038)
- Created a USB Ubuntu and ran the program but suprisingly still the same problem – stuck at ‘waiting for device’ (see snapshot attached).
So I’m a bit confused right now. From the above it seems to me that the Kindle is not talking to the PC.
- But if in Linux, it doesn’t work (which from what I read doesn’t require a driver?) then it could possibly be my cable.
- But the cable did work when I rooted in 6.2 and it also worked initially when I used KFU. And also, I tried with 4 different cables.
​- Am not sure if the cables are ‘factory cable’ – but it did work initially.
I’m stuck here. Any help/advice would be deeply appreciated. Thank you.

A few things that might help you...
1) If you have FFF 1.4a, you can access its boot menu and have the device boot normally or into recovery. As it boots up, look at the power button LED and watch as it goes from a bright green to a dim green. As soon as it goes dim, press and release the button to bring up the menu on the screen. You can then flip through the menu options by repeatedly pressing and releasing the power button. Leave it alone for a few seconds and it will continue to boot using the selected option.
2) If you don't know whether or not you have a factory cable, you probably don't have one...
http://forum.xda-developers.com/showthread.php?t=1550999
3) For the computer to issue fastboot commands to the device, it must already be connected to the computer before booting into fastboot mode. That is... you cannot boot the KF into fastboot mode and then connect it to the computer. If the computer is <waiting for device>, try turning the KF off by pressing and holding the power button for around 20 seconds to shut it down completely, then turning it back on again. For more information on fastboot....

If the above suggestions don't work for you, make sure you are getting the expected hardware IDs shown in the previous link.

Thank you kinfauns for your immediately reply.

Unfortunately this doesn't happen on my KF. The power button is bright green. And the bootlogo is persistent and remain bright on the display.
I've tried repeatedly pressing and releasing the power button but didn't work.

I tried this method but nothing changes - when I turn it back on, it goes back to the bootlogo. KFU still says <waiting for device>.
Also tried 'Temporary fastboot mode' - 'fastboot getvar product' - still <waiting for device>.

My KF doesn't show up on 'Device Manager' - no yellow question mark or whatsoever.
When I manually installed 'Android ADB Interface' - it shows an yellow ! and even after I connect the KF it still shows the yellow !.
Current hardware ID (for 'Android ADB Interface' with yellow !): usb\vid_0bb4&pid_0c01
Device status: This device cannot start. (Code 10)
So I guess, I will wait for my factory cable, unless you have any other suggestions? Thank you.

I have no idea what that ID number is, but it's definitely not the one you should see for fastboot. That means you have those drivers installed on the wrong interface. I also suspect your bootloader might be corrupt or otherwise not functioning correctly. Using the factory cable will give you a better idea what's going on since you can (almost) be certain that the device has put itself into fastboot mode. Then you can focus on getting the drivers installed properly for the interface that appears in the device manager. As a last resort, you might have to open up the case and use USB boot (in Firekit) to flash a new bootloader.

Just quickly skimmed over your thread but have you tried holding down the power button for a minute or so and then powering it on? I would tend to agree with kinfauns that somehow your bootloader is broken if so a factory cable will do nothing only firekit will remedy a broken bootloader that's why I ask about the long press power off attempt...

I pressed power button for more than a minute - tried 2 ways:-
- with the KF on - it switches off and remains switched off.
- with the KF off - it switches on for a bit and then switches off and remains switched off.
I'll just give the factory cable a try when it arrives - will update here again. Hopefully I don't have to open up the case.
Thanks kinfauns and Thepooch.

Just to update - the factory cable didn't do the trick. KF still stuck at KF blue/white logo - the bootloader must be corrupted.
Hence am going to try opening the case and flash a new bootloader. Wish me luck - will update again soon. Thanks.

Please help me My Kindle is stuck at black screen after Kindle Fire logo. I have Android Composite ADB Interface driver installed, but when I plugged my Kindle Fire to my PC, it detected as a USB Mass Storage, and won't connect as an Android device so I couldn't do anything with adb commands or KFU...

Can you tell me how u fixed the problem.I am having a similar problem after my using the kfu to root the device.It got stuck at <Waiting for device> during the root process.It had been shown online in the ADB status before that.I removed the cable after it got stuck at the <Waiting for device> during the root process.Now it is stuck at the kindle fire logo after turning on..I tried to reconnect the device and run normal bootmode but cant do that as now the adb status shows offline.Waiting to receive any help possible.

I have found in some cases if things haven't gone to far there are two things that will sometimes work. Firstly rerun the driver bat with the device connected sometimes you get lucky. Secondly if standing to long <waiting for device> simply hold the power button till it turns off, then power it back on while connected and it should then detect it to continue the process.

Hi
I also had the same problem when i tried rooting my kindle.. but was able to solve it and root it.. Try following the below steps.. it should help you..you need to have the drivers installed
1) Check the device manager.. do u see USB Composite Device (with yellow exclamation)
2) If you see that uninstall the driver and restart your kindle too.. once your kindle restarts it will come up as Composite device (with yellow exclamation) under other devices
3) Right click this device.. update driver.. Select install from a list or specific location (Advanced).. click next.. select Dont search I will choose the drivers...
4) Click next... select Android ADB interface drivers.. it will show a popup.. accept it and carry on
5) Now if all goes through well ur device is detected..
6) Next step is download the KFU from the forums.. Run the executable.. select option 1..and select normal boot..
7) Your kindle will reboot and start working normally
Try and let me know

[Q] PC wont recognize my kindle fire 1

Hi,
I get almost new kindle fire 1 but computer won't recognize it. I tried with another one and computer recognize it fine. It's stuck in a boot logo. I don't have any more info about it. Any chance to get it work?

I've had this issue before as well, you should be able to get into recovery. Just make sure your fully charged and keep trying to get into recovery by pushing the power button down in order to select 'recovery' if you've got TWRP.
With your PC though, if it's never been recognised by that computer before then you need to install the drivers for the kindle fire. They should be around this forum somewhere, probably in the stickies if I'd have to guess. And if that still doesn't work for you, download a program called 'moborobo' which should automate all the steps for you and allow your computer to 'see' your kindle.
Good luck.

Hi,
Yes i find solution for my problem by making the Factory Cable and i get it in the fastboot mode. After that I tried to install FFF and now it is completely dead
I don't know why this happened at all... My kindle even doesn't show the power led end it stays off. Later tried with Firekit but with no luck

[Q] Kindle fire HD 8.9 will not boot, can not see in my computer

I can not get my wife's fire HD 8.9 to boot. When I turn it on the Kindle Fire screen appears for about 5 seconds, then the Kindle Fire goes out, but the screen is still backlit.
This device is completely stock with no modifications. It did this when I turned it on one day, no previous problems.
I tried holding the power button down for up to 2 min. After I hold the button for 10 seconds the backlight goes out and the kindle is completely off. I tried letting the battery go completely dead, then charging it for several hours with no change. I tried running fastboot, but it is stuck at <waiting for device>. My computer does not see it at all. I do hear the chime that something was plugged into the computer immediately followed by the chime that it was disconnected, but nothing shows up in my computer at all.
Is there any hope for this Kindle, or is it bricked for good?

So I assume you're on windows. That beeb you hear is the fastboot mode you need to load drivers really quickly during that beeb. At that point fastboot shoukd work and you can issue a command to get into the factory restore.

I got it working again.
The problem was simple, I did not have any drivers installed on my computer for the kindle (I have never plugged it into this computer before it would not boot). I found the drivers to download here: http://forum.xda-developers.com/showthread.php?t=1890413
I was then able to get it into fastboot and recover it with instructions from this thread: http://forum.xda-developers.com/showthread.php?t=2011126
