So I bricked my FireTV last night during an upgrade to rbox's latest fw...
Short story is, it got to the Amazon app optimization after the flash fine so I went back to the computer to start working on the second box while it did it's thing. I mistakenly sent the reboot recovery command to the box that was optimizing itself. I didn't notice I was sending the command to the wrong box until I saw that my second unit was not rebooting to recovery.
Needless to say, it now no longer boots to any logos, and does not turn on at all (no light when plugged in, not even for a split second).
What are my options to unbrick? I'm taking a guess that the SD reader/eMMC method is the only one. If so, is it possible to retain an unlocked bootloader/etc with this method? I've read you'd lose it, but I'm not familiar.
If someone could point me in the right direction that'd be awesome. I tried google but it's filled with loads of outdated or unrelated information (mostly debricking if the amazon logo appears) or info from when the initial hardware root method came out.
i am in the same boat. if you find anything let me know.
after following the downgrade tutorial, I executed the command as instructed adb reboot recovery
device reboots into recovery,
update starts..... after while reboots...
upon reboot
no light on device no logo on screen - black screen
connecting to win7 machine with USB cable it initially recognizes the box, but cannot connect with either ADB nor FASTBOOT - searching for device

At least you can connect with USB! I get no connection at all to the pc with a A-A cable.
I would suggest for you trying to get the timing right and initiate the fastboot commands right when the device is recognized.
You people need to reflash your partitions, this happened to me months ago. Can't search for the thread now, I think the steps were in the FireTV1 5.0.5.1 thread...
my device bootloader is not unlocked. I was following the steps to downgrade firmware in an attempt to unlock the bootloader.
in Win7 Control Panel > System > Device Manager the FireTV1 appears as QHSUSB_DLOAD - i think I am also going to try this ... http://forum.xda-developers.com/showpost.php?p=66961740&postcount=676
thanks for the advice ldeveraux, ill take a look.
Ordered the eMMC adapter from exploiteers. This is likely the only way I'll be able to fix this as the USB A-A cable is not detecting my FTV
Well I managed to get my device talking with an A-A USB cable while waiting for my eMMC adapter. So now to flash
Is there a way to recover with this method without losing the ability to unlock the bootloader? Bootloader was unlocked prior to the brick.
UPDATE: annnddd it didn't work for me. Was getting I/O errors while writing and now the device no longer gives me partitions in /dev/. The usb device still shows up however.
how did you get the /dev/ partition to appear ?
which linux distro did you download / install as I cannot see any partitions on my device
did you use the linux in a VM ? & did you have the windows drivers installed beforehand ?
thanks

I rooted my Kindle Fire about a month ago with KFU. Everything was fine until I turned it on one day and I got stuck at the Triangle screen. None of the reboot tricks work. The interesting thing which I think is what is stopping me from being able to successfully use other methods is that when I plug my Kindle Fire into my computer via usb, it connects, and then disconnects (the USB) about 2 seconds later. I've tried different ports, etc. Any help on this issue would be greatly appreciated. I've read over multiple things, but don't see a mention to the kindle being disconnected via usb so quickly, thus stopping me from being able to do anything.
Care to elaborate on what "reboot tricks" you've used?
What version of Windows are you using?

I've tried the rebooting the Kindle while trying to reset the kindle to booting "normally" within the KFU. I've tried holding down the power button on a reset, then pushing it again until it is orange, none seem to work. I'm confident I could get it to work again if the kindle did not disconnect from my computer so quickly. By this I mean I hear the "usb chime" when I plug it in, then within seconds the disconnect chime plays. During the brief few seconds it is connected, it shows up on my devices list, but obviously when the usb disconnect chime plays, it disappears off of the device list.
edit: I'm using windows 7 Ultimate.
Can anyone help me? I may add that My Kindle Fire was originally rooted with the KFU and worked perfectly fine. I literally turned it on one day, and it got stuck at the triangle screen. The connection issue of it disconnecting so quickly is what is stopping me from fixing it I believe. Please help.

Figure out what device drivers are getting loaded when the connect "chimes" sound in Windows. If you confirm that they are correct based on the contents above, you must stop the temporary fastboot, set the bootmode to normal using fastboot, and restart the device.
I suspect you've got more issues than just getting stuck on the bootloader though... If you are getting disconnect tones in the bootloader, that means it's attempting to boot into something, but obviously unable to do so.

The disconnect tones are from my computer, the same tone when you unplug a usb (since the kindle is plugged in via usb) I can't change the bootmode because the usb disconnect chime happens literally 2 seconds later, and the kindle is disconnected, all the while the kindle is still on and showing the triangle screen.

Have you checked to see what drivers are getting loaded? Do you know what device should appear in the device manager? Have you tried to stop the temporary fastboot countdown? Do you know how to stop the temporary fastboot countdown?
If you aren't willing to try out my suggestions, there's not much else I can do.

Yes to all those things. The device does indeed pop up in the device manager but only for the brief 2 second window before it disconnects. I've tried multiple usb ports on my pc with the same result. The kindle does not power off in any way when the it disconnects from the pc.

I've tried to reset the bootmode via the KFU method recommended in the guide posted here (normal, 4000 and trying to reset when it says waiting for device) The device pops up in the device manager as an "unknown device" which may be a problem with the version of the drivers im DLing. I'm using KFU version 0.9.6
When I first DLed them it seemed as if the drivers were installing correctly, when I plugged in the Kindle is said drivers were being installed but it failed because the device disconnected after the 2 seconds.
Rapid disconnects are nothing unique, they're simply driver or USB problems. Any malfunctioning USB device will give you that same sequence. Anyways, it's difficult to get out of a boot-loop without ADB so let's try to get that USB working again.
First, do you have a bootloader (like FFF) or a recovery (like TWRP) loaded? I'm not sure the USB driver will work during boot without at least one of those installed.
Second, boot into TWRP, then try to fix the USB from the computer end. Uninstall the drivers, download a fresh batch, reinstall drivers, reboot. Use explorer to check %userprofile%\.android\adb_usb.ini and make sure 0x1949 is there. Also check Kindle Fire Utility\drivers\kindle\android_winusb.inf and make sure whatever hardware ID is showing up in device manager is in there.
BTW, what device IS showing in Device Manager after the disconnect? Use right click, scan for hardware changes.
Third, the USB cable or ports themselves may be at fault. Try a different cable, and try a different computer. Also, reboot often.

Thanks for your response, I will go through these and report back when I get back home from class.
ok, now I have my kindle being recognized by my computer as "android phone" with the sub of "android adb interface." If I have read the guide correctly that means it is in fastboot mode. However when I open kfu it says the kindle is offline.
If someone would be willing to help me out through Skype I would gladly appreciate it. I'm really at a lose as to what to do at this point.
and no stupidly I do not have FFF or TWRP loaded, since I first rooted it when I was a super noob. The usb driver seems like it should be able to work according the the Kindle fire beginners guide, but KFU does not recognize the kindle even though my computer does.
Your guide sounds very good, to me. Hope it helps someone. I'm not sure it will help me.
I have searched here and google, in general for my specific issue. It may be available but, after 4 hours, I haven't found it.
While attempting to use TWRP to change from Cyanogenmod 9 to 6.3.1 from a TWRP backup, I was running Wipe and fat-fingered System Wipe. By the time I noticed it, to late. Now the KF will show the Kindle Fire boot logo, flash it a couple of times and hang.
WinXP will give the welcome "Beep" when I plug the KF in. KFU shows the device is off line and WinXP does not show it: please insert disk in drive F: is the dialog.
drive F: shows up when I plug the usb cable into the Win system so the usb is at least recognized.
The KF will power on when the usb is connected to my Win system.
I have used KFU to try to get to fastboot. No joy.
adb shell does not work, since adb does not see the KF
I have reinstalled the drivers for adb, twice.
adb get-state does not see the KF. KFU does not see it, either.
I have followed several of the suggestions from XDA forum and nothing has helped.
Am I stuck with a brick?
Thanks in advance for any assistance.
Note: I asked the mods to move this post into the Q&A section.
Your device can be fixed. It's not permanently bricked.
The problem is that you currently have no easy way of getting the device into fastboot mode. The stock bootloader does not enable temporary fastboot mode and with a broken system, you will not be able to set the bootmode to tell the bootloader to enable fastboot mode.
Your next best way of fixing this is to get a factory cable. The factory cable will tell the bootloader to enable fastboot mode. Then you can flash a new recovery and use it to flash a new system.
The last way to get into fastboot mode is to build a Linux system, open up the case, and use Firekit to send a new bootloader over USB and use it to enable fastboot mode.
Most people would probably opt to buy a factory cable than open up the case and tinker with the motherboard, but the choice is up to you.
EDIT: Unless you changed the setting there's a good chance that TWRP is still there since TWRP doesn't backup/restore the recovery partition by default. When you get the device into fastboot, all you'd have to do is set the bootmode to 5001, reboot into TWRP and restore your backup. Either way, I'd recommend installing a custom bootloader so it's easier for you to get into fastboot mode the next time around. Take a look at FFF...

Many thanks! I have started on the cable modification. Now to see if my soldering skills are still there.
The KF is a great device that can do much more than Amazon has set it up to do. I was very happy with CM9 but it was a battery hog since the display was persistent at 100%. Any idea if there is a better ROM available until CM9 is complete?
I will post when I get my KF back up.
Thanks, again.

Good luck, sounds like you have been given good advice already...
To answer your question about ROM's, I am running the latest gedeROM 1.35 on mine and the brightness issue is fixed and battery life isnt bad once you turn down the brightness. Rarely do I need mine brighter than 50% and that is using it some in my car during the day.
Hi. I am really in a jam here. I have read a lot of documentation and still am not getting anywhere. I bought my sister a Kindle Fire for her birthday, and after reading the Kindle Fire for Beginner's Guide, I was able to successfully install Cyanogenmod 10.1 It was working fine, but I gave it some thought and decided she would be better off with the stock software, so I followed the instructions here to revert.
However, somewhere in that process I bricked the device. I went through the installing the Amazon software again in TWRP and told the device to reboot, but it is now stuck on the boot screen and will not respond to adb commands I send it.
I used the Kindle Fire Utility to install TWRP again, and it said it was successfully installed. I tried to boot into it through the Kindle Fire Utility menu, but it is still stuck.
It just so happens that I have a fastboot cable for this, so I plugged it in and tried to boot into recovery by issuing
C:\kfu\tools>fastboot oem idme bootmode 5001
It just says:
<waiting for device>
and nothing happens.
I don't know what else to do. I do think this factory cable put me in fastboot mode because the Windows device manager is showing "Android ADB Interface" (which according to Kindle Fire for Beginners is what it is supposed to say if the drivers are good and I am in fastboot mode), but I do not know how else to make use of this.
I am really stuck here, and I hope someone will take the time to help. My sister's birthday is in two days and I need to get this Kindle fixed and in the mail

Thank you for your reply! I ran the Kindle Fire unbrick tool with the option "Stuck at logo," and it said "Congratulations, your Kindle should be unbricked. However, nothing had changed. So I ran it with the option "Other . . ." It said:

I have left it like that for ten minutes now and nothing is happening. Do you think it is working? I'll leave it alone for an hour or so I guess but I'm wondering.
BTW, for this I just used a regular USB cable and not the factory one. Is that right?

I was thinking the same thing. Unfortunately I don't have another PC running Windows. All my others are running Linux, and I don't know how to get the drivers working.
I think I will borrow a laptop from a friend tomorrow and see if it works. It is my sister's 17th birthday today and her present is late!
In the meantime, though, does anyone know how I am supposed to use this fastboot cable? I have looked around and I see a lot of tutorials about how to unbrick without a fastboot cable, but none saying how to do it WITH one. I thought the cable was supposed to make it easier?
Thanks for the help.

I think you may need install the firefirefire utility first to help you out of bootmode sucking. After you successfully reinstall the TWRP using unbrick utility, you need change the fastboot mode to normal boot, the firefirefire can help you choose,

Well, now the Kindle Fire is no longer being recognized by my computers. I borrowed another Windows computer like I said I would, but when I plug in the Kindle, the Device Manger does not even register it. Also, usually when I plug it in, the computer will realize I have plugged in a usb device and respond with that little pop up at the task bar, i.e. to let me know it sees a usb device and is trying to install driver, was not able to install drivers, or whatever. But now nothing. The computer doesn't even see it.
I have tried it on two different computers with three different cables and it's the same thing. I have restarted the computer and reinstalled the drivers over and over again and there is no difference. What is going on? It was seeing the Kindle fine before I tried the Unbricking Utility.

I'm assuming you know for sure this was a 1st Generation Kindle, right?
I had this problem once and basically formatted my computer. The driver was the issue and I couldn't uninstall it completely. Using my drivers solved this. I get the feeling you're still trying to use the drivers that came with the utility (don't they're often trouble)
However, assuming you are using the correct drivers (the ones I linked for you).... Boot into TWRP and wipe everything. Don't just use the general, click the advance options and wipe everything (selecting all options manually).
No connect your Kindle and don't worry about it not showing up yet....
Mount your SSD (should suddenly find your kindle) and upload this ROM
http://forum.xda-developers.com/showthread.php?t=2211872
Now if you can't even load TWRP (when you turn on the Kindle, you'll need to hold the power button to bring up the menu, then quickly hit it a few times until its on recovery).... But if you can't load TWRP at all, its time to get a factory cable.
If you have a factory cable and still can't find the device (and assuming you're using the right drivers, on a fresh install) .... As someone else who knows how to do this. Because past that, all hope is lost.

Hi, My name i Jonah and i have a Kindle fire (5th generation) That came stock with Amazon's Fire OS Bellini 5.1.1. I tried to flash Cm12 with the app FlashFire (https://www.youtube.com/watch?v=NaCBSuUuhRE&spfreload=10) and during the installation i noticed it stopped for a while and didnt do anything. So i waited then 10 minutes later i decided to turn it off and turn it back on to fix it, when it started to boot up it showed the Cm logo just like as if it was running Cm12. So i waited, maybe 5 min at the most and it still would not turn on. So i turned it off, went online to see ho to get out of a bootloop. Rootjunky said to Turn your Kindle off and run ADB and Fastboot as a command from where you installed your drivers. Then he said he said to enter Recovery mode by pressing vol down and the power button. It is suppose'd to say Recovery-Mode in the corner but it just kept showing the Amazon logo. Im worried i screwed up and broke my new tablet, i can't return it because it's against Amazon's policy to root or mod any content of Amazon's, Plus ADB isn't working i can only access fastboot. I tried fixing it with the stock charger also but how do i know what kind of Android charger should i use?

My son is trying to get his kindle fire back up and running. With not much success. He was reinstalling the software and must have wiped the device clean as now he cannot get back into recovery mode. When installing FFFF it says that there is no exec directory. He ordered a factory cable adapter from black hat under the impression that this would force the device into fastboot thus recovery. When he attached the adapter all that happened was that it went back to the kindle fire logo and is now showing offline status unknown. Before at least it was showing online. Are we mistaken that it should go to recovery (blue and white) kindle logo. We are a little tired of messing with it and are thinking of calling it quits. Any suggestions would be much appreciated. We have turned off and on, installed drivers, and switched cables to no avail.

You almost got it right. The error you received means the shell is no longer accessible and therefore unable to send necessary shell commands, like those used to change bootmodes. In order to fix the problem, a factory cable is needed to access fastboot, which gives you an alternative method of changing bootmodes (to access recovery) or flashing partition images (i.e. installing recovery) by use of fastboot commands. But the factory cable does not actually boot the device into recovery on it's own though.
Here's where it get's a little tricky though. Unless you know what to look for, it's difficult to know whether the device is actually in fastboot because the only thing that will be displayed on the screen is the Kindle Fire logo. You'll know if the device is in fastboot because the Kindle Fire logo will stay brightly lit, indefinitely. If the Kindle Fire logo flashes and/or gets slightly dimmed, then you'll know the factory cable you have is defective. With that being said, however, just because the device boots into fastboot mode, doesn't necessarily mean the computer will communicate with it. For that, you need working drivers.
Long story, short...you need to confirm whether the device is actually in fastboot before you can go any further.
Thanks for the reply. I looked at the logo this morning and it came up brightly lit with no change so I am assuming it is in fastboot mode. That being said the device, in device manager it comes up as unknown usb device. Before it would come up as kindle and I would install the drivers and it would come up as an android phone adb composite. I went into device manager and tried to update the driver manually and windows tells me that the correct driver is being used for this device. I did unplug the adapter and go back with a regular data cable and that made no difference. Do you need to force it to use a different driver. I am trying to use the drivers that came with the KFU I downloaded.

Kindle drivers are notoriously touchy. Try uninstalling/reinstalling them a couple of times. I predict they will suddenly start working and you can proceed with installing custom recovery/rom.

Thanks for the respone, I have installed and uninstalled to where if I here the computer connect and disconnect one more time I might throw it against the wall. Are there specific steps that I need to take other than ordinary to unintall/install the drivers correctly or maybe drivers that are more sccuessful than others.
Ok, after sifting through a number of threads. I read where adb and fastboot are mutually exclusive and adb will not see a device that is in fastboot mode. Is that correct? And when you install the drivers with KFU does that contain the fastboot drivers? Or should you download SDK platforms tools which contains both? And then run fastboot commands to flash a recovery? If so, is there a good tutorial for someone that does not follow directions well?

Yes, adb and fastboot are mutually exclusive but the same drivers should work for each. You can try the drivers located HERE, or read the topic on understanding driver installation located HERE.
Of you are still unsuccessful in communicating with the device in fastboot while using fastboot commands, you may have to restore it with Firekit using the "shorting trick".
OK, here is an update. I was able to get the device into recovery and TWRP. Not sure what I did differently other than maybe standing on one foot, facing south and staring at the stars, but it worked. When all of this started it was right after my son updated the software to 6.3.2 via wifi, maybe something went wrong. So last night I was able to flash 6.3.1 back to the device and was told that it was done succesfully. Using adb I can see the device in recovery and the shell lsiting is ~ # ←[6n which I guess is good as it said there was no shell before. So now my question is could it possibly be a corrupt bootloader on the device as well as it was hung at the fire logo. If so, do I need to reinstall the stock bootloader and if so where do you find it or does it come with the software flash?
I have succesfully got the update file on the kindle, did all the wipes selected install and now seems to be hung at veryfing filesystem and partitions sizes. Can someone tell me how long a flash should take or is something wrong? Since I have never done this before I have no idea.
Sadly i had to come to the painful conclusion that my problem relies at this point on the data detection of the phone itself.
I have read tons of tutorials pointing to adb or fastboot upgrades and different stuff and methods to update. I'm stuck in 2.20.40.139 and cannot find an update within the OS. I will enumerate now the things i see in order to clarify this situation.
_USB debugging on or off makes no difference.
_MTP or the other mode returns nothing. No detection on device manger in windows.
_Phone always charges when plugged to USB ports.
_Tried 4 cables and 3 pc's all of them tested with other phones and tablets.
_On fastboot mode nothing happens and device is nowhere to be found.
_ADB is the same. adb devices shows nothing for this.
_Recovery returns an error as if it tries to update something that isn't there MOFD_SUPDATE.zip
_after that error i get into recovery pressing power+vol up for a few seconds.
_did a factory reset on the phone and wipes in recovery.
_copied file in root of the phone. Detected the update. failed when trying to apply.
_bootloader in fastboot shows unknown. serial is 0123456789ABCDEF or something like that (serial was ok before i used the bootloader unlocker from ASUS website)
i can't think anything else for this right now... it's really driving me crazy since android works without an issue. Phone is not rooted or even has been tried to root.
If someone knows or can think anything regarding this please help me out. There's nothing i like more to share thoughts and ideas to have this updated.
Thanks in advance,
