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.

What is the device name that comes up?
What command did you send to stop the countdown?
What did it output as a result of the command?
What makes you think that it should power off when you disconnect 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.
I looked at almost every thread I could see that sounds like my case but in every one the device is at least being recognized by USB on the computer, in my case it has absolutely no recognition.
I had custom gedeROM. gf didn't like it and so I decided to go back to stock.
within TWRP I did Factory reset, then installed the stock bin file that i renamed to update.zip. Install went through properly so I restarted.
Now it is frozen on Kindle Fire boot screen, and it won't go further. Attaching it to a computer with USB will power the Kindle on but the computer will not detect it, tried on 3 computers, Windows 7 and Linux. I have tried to use all forms of unbricking, everything except opening the Kindle. But since the device isn't being recognized by USB at all on any system I don't know what to do.
With a Factory cable help with this?
Thanks for any help.

Did you have adb and fastboot setup on linux when you tried?
I'm pretty sure I did, I used the firekit and that didn't work as well. how do I check if adb and fastboot are for sure running when in linux?

Installing Amazon's stock update.zip gets rid of FFF and TWRP, so at this point, your only choices are either getting a factory cable (recommended) or cracking open the case and resorting to the USB short trick + firekit.
OK, I have an order for the Factory cable coming so hopefully that will do the trick. Thanks
I have a kindle fire which wasn't doesn't connect to the computer. I get an error message such as "USB device not recognized". I had rooted the kindle fire and I thought that this problem could have been because of the rom or some kind of kernal error so I installed the stock rom thinking that I will just re-root if however the connection problem still was still there. So now I have kindle fire which is not rooted so doesn't have google market and I want to root it however cannot find a way to get it connected. I have tried 3 different computers and many different cables however still no success. I have also tried reinstalling the drivers, turning off and on the kindle fire with the cable plugged in. Could the port on the kindle fire be broken even though it charges fine. Also, would a factory cable help because I don't want to order it if it doesn't work. What other options do I have? I live in UK and this kindle fire is the 1st gen which was only available in US so cannot send it to amazon for checking.
Your help will be appreciated :good:
Do you have TWRP installed? If so, try connecting it to the computer using the USB mount via TWRP...
I have 3 Kindle Fire tablets that I installed a JB ROM on for some friends, and one will not connect to the computer (except via TWRP). I never did figure out why, but I could copy a ROM and Gapps to it while in TWRP. I set them all up the same, and that one still doesn't connect.

Plug the device in and manually uninstall the unknown device that shows up in Device Manager. Then Find the directory where the 'android_winusb.inf' is stored (somewhere in your WINDOWS directory), delete it, and start over.

If this is the stock OS, then I would say that is definitely a problem. You may have some system files missing for detecting USB devices plugged in as UMS. Are you able to access any flash drives?

Yes, my computer detects my galaxy s2 and other flash drives perfectly. Is there any way of rooting the kindle fire without connecting it to the computer? Because all i want is to have the play store on my device
The new version of KFU seems to have a much more effective driver install. You should try looking into that.

I am having the same issue with my KF2. USB Comms disappeared in terms of the device being recognised by XP but strangely fastboot worked and I was able to load CM11 on the device after downloading it via wifi and installing TWRP via fastboot. Still no USB on CM11 but its briefly recognised for a split second when it first boots. Monting the volume via TWRP has not effect either.
Have tried a variety of cables and have tried connecting the Kindle to an XP netbook, downloading fresh drivers etc etc etc.
Any ideas out there?

I just rooted my kindle fire and then i wanted to add some ROMs to it like Android 4.0 or 4.1 and when i went to plug it in the driver doesn't show up. I looked online but i can't find any answers! I tried using other cables. rebooting my computer. doing a hard reset on the kindle. i even did a factory reset on the kindle fire!!! The Root is still on it though!!!! Ugh How can i make the driver show up?!

First off, did you use KFU?
OK, either way, make s sure the drivers from that are installed.
Probably restart your computer after you install drivers.
If that doesn't work, reboot your kindle, go into TWRP, mount your sd partition with it connected to your computer.
Hopefully one of these work.

Did you try different USB cables? Is ADB Debugging enabled under Developer options? If so, you might try disabling it and then plugging your KF in. That may fix your recognition issue.

Go into Settings -> Storage and select "USB computer connection" (may have to tap on the settings button in the top right to get this option, depending on what build you are using). Make sure you have Mass storage checked.
I've found some of the earlier CM builds had USB issues, but the newest ones work just fine (CM10.1/SG7 definitely works, as does Smooth ROM 1.5+). If all else fails, go into TWRP and mount your SD card from there instead.
nice catch, @zerbey. I didn't even think of this. personally, MTP works for me and mass storage doesn't work. experiment with both to see which works.

So, I think in my haste to remove root and go back to stock, I have bricked my firetv. I can no longer connect via ADB. I have tried using a usb-a male to male x-fer cable to connect via computer, to no avail.
My firetv just sits at the white amazon logo. I have connected a keyboard and tried the alt-i-print screen (numerous times) as well as hitting the home button. It appears as if it is just completely unresponsive. I have even tried loading a rom onto a FAT 32 thumb drive, renamed it update.zip and hoped that it would pick up the file upon reboot (I got this idea from another thread here)....also to no avail.
I think the thing is beyond hosed and may have to swap one out at the local big-box store.
Does anyone have any other ideas, because I'm all out.
Thanks!
When you connect an A-to-A USB cable, does it show up listed when you type "fastboot devices"? (Note that you should connect the cable while the Fire TV is powered off, then plug in the power with it already connected to your PC.)

It does not. I've tried several times to reboot while connected to the computer. I believe the transfer cable to be good because it is brand new and the software/drivers run/get installed when the cord was plugged in. The firetv box, the best I can tell, is just completely unresponsive. Beyond 'booting' to the amazon white logo, it does nothing and responds to nothing.

Nothing obvious. I've expanded every node and see nothing other than some generic USB hubs and controllers, but nothing different when the devices is attached to the transfer cable than when it's not.
