Boot into TWRP... then follow my other directions.

From the op of KFU thread:
Known Tricks
•If you end up stuck at the yellow triangle, in KF Utility select Boot Normal, wait for it to say <waiting for device> and then press and hold the power button 20 seconds until the fire turns off, then when its off turn it back on. This sometimes happens, I have yet to find a clean solution
•If you end up stuck with a yellow triangle, do not EVER unplug it. Leave it plugged in. Check the windows drivers to make sure it isnt showing as "kindle" again. Fastboot is different and can cause this.
That fixed my issues in fastboot when I was trying to install TWRP the first time. If that doesn't work then [URL="http://forum.xda-developers.com/showpost.php?p=20945694&postcount=506]check out this post[/URL]

I cannot boot into TWRP because the kindle keeps shutting off because it is dead. It isn't read by the computer.

Plug it into electrical outlet and leave it alone for three hours.
While waitin for three hours assess your problem and find the solution. Search.
Then execute solution after fire is charged.

Will it charge even when it keeps turning on and off?

Yes it will keep charging.

It did not charge... At least I don't think it did..

When you plug it in do you get a solid color or is the light flashing?
When it's plugged in to the wall and the light is solid you should perform a hard reset by holding power for 20 seconds. This will fully shut down your KF and it will accept the charge

If by flashing you mean turning on and off by itself than yes, it is flashing.

Please help..I'm losing it
Same problem here. It does not seem to charge when plugged into either wall or computer. The green light flashes on and off repeatedly and the recovery screen (yellow triangle) just comes on and off (it eventually just goes black while the green power light continues to turn on and off)
in order to help myself I have done a few things
1: KFU isnt working.
I updated the drivers through KFU
I tried to change bootmode to "normal" and it hung on "waiting for device" I tried hard reset here and nada
2: I tried booting into normal fastboot 4000 through command prompt and hung on "waiting for device" tried reset..nada
So just like the poster above I cannot get into TWRP as the computer never truly recognizes the KF. This all happened when my wife turned on my kf and didnt know what the TWRP was and hit the power button for recovery. It loaded back to the stock kindle set (I had been using CM7) and since then I've been eating FUBAR soup as it doesnt work
Seriously..im pulling my hair out here...any help? I'd try to return the kf to Amazon and save myself the pain but I think we know what would happen when they plug it in and see the flashing triangle...lol

1. Plug your kindle in to the wall for 3 hours like someone mentioned previously (it will charge) The issue with the device being in a boot loop has nothing to do with the kindle fire not charging, this is perfectly normal if you have modified system files and the system can't boot the Android OS. It is also normal to never get past the Yellow Triangle if for some reason that you have changed to FastBoot mode. (Some people may be misinformed thinking that FastBoot does what it sounds like it does (boot fast - not the case), that's how this usually happens)
2. After you know the kindle has been charged for at least 3 hours on a known working power outlet. Press and hold the power button on the kindle for 20 seconds or longer until the device powers down completely.
3. Press the Power button to turn the kindle fire back on, and be ready, as it comes back on press the power button as soon as the Yellow Triangle (firefirefire) logo first appears. Press it up to 5 times rapidly. If you get to TWRP then you can relax. - If you get to the Yellow Triangle and you have pressed the Power button a few times but it is still stuck in a boot loop before giving up try one more time to shut down completely and reboot while pressing Power button rapidly.. You want to be sure to do this before the Yellow Triangle screen goes dim .
4. When you are in TWRP you should be able to use KFU or ADB. You may want to change the boot mode if it is not already to "Normal" if you are having this problem with "Normal" then try to reflash the Kindle with a recovery image or a new ROM.
Hopefully you can at least get to TWRP by following this, so that you can at least flash the kindle with a different update.zip. Good Luck

Charged like you said...still no charge. Flashes on and off and when you pull the power cord goes to black like its dead and will not turn on at all whether you hold it down or just push it...
Never had a problem like this before, could always at least get it to turn on or off not a mix of both lol. Thanks for the help...any more ideas on how to get it where I can at least get it into recovery?

I'm experiencing the same thing.

I'm still confused... are you guys trying to charge it while it is in the boot loop?
Have you tried turning it off (holding down the power button for 20-30 seconds until the screen and the power button go dark and stay dark)? And then plugging it in? I wouldn't expect you to see the firefirefire triangle if the device is off while charging.
The other thing that you might want to look into is the factory cable. Supposedly charges the device and can access it w/o any battery power at all - if I understand that thread correctly.

The point is you can't turn it off, it's dead. If you try to put it on charger either through wall charger or USB, it blinks on and off repeatedly and the power button does nothing at all. The computer won't recognize (tried several diff ports and pcs)
I'm beginning to think the factory cable is my only option to bypass the bootloop and fix it, just hoping I wouldn't have to wait so long for a cable or drop 40 bucks on it. I guess that's what I get for messing something up!

I left it bootlooping for like 6 hours on the charger. Unplug it and you can't turn it on. Plug it in and it bootloops and you can't turn it off. So is this just bricked for good with no possible fix?

You may want to PM SkOrPn, http://forum.xda-developers.com/showpost.php?p=23024666&postcount=108, seems like he has them for $15/$19 depending on length (if your location is accurate.)

Kindle fire turning on and off by itself and won't charge
The only way I know around that problem is unfortunately to remove the back cover and remove the battery with a good adjustable power supply apply 3.7V to the battery for a 30 to 60sec it will draw approx. 3.4A and over the 30 - 60sec the current draw by the battery will drop. Be very careful as you don’t want to blow it up. Put the battery back in and you should find the kindle will charge again. Good luck

Hmmm, I wonder if the factory cable would be an alternative as last I checked an adjustable power supply (if you're without one) can run 70-100 bucks which is half of the kindle itself, I'd almost just take my chances sending it back in to amazon. Thanks for the help though from someone who has had the problem

Problem with kindle fire

I hope this is In the right area I rooted my fire and installed a custom rom added fff and the recovery ect well yesterday when I press power nothing happens when I plug it up to power it turns on flashes the press power for recovery square then shuts down flashes it again it does this over and over never ending it wont stay on long enough for me to do anything I tried letting it charge all night I tried different power cords when it plugs to my pc it does the same anyone have any ideas

Also want to add I rooted it with the utility over 3 months ago it was working fine til yesterday I made no changes to it

I would suggest trying this first as it sounds like you are in the recovery loop. Another useful tool is to "re-stock" it using this utility. Maybe not the best idea if you haven't done a recent backup but if you have tried everything else these usually work to get you going again.
Also it can't hurt to go through this thread and see if someone else has suffered the same problem. Between these 3 threads you should get your kindle working again.

You have a dead or near dead battery. Plug in the oem charger and see if it will charge up.

Try this and when you plug it up via the OEM charger does it turn on or does the light on the bottom at least light up?

Odd if it's turning on your PC should be able to make a connection long enough to adb it. Have you tried pressing the power button a few times to get into "recovery" mode? The exact instructions are "press the power button when the light dims green" however I have noticed it works for me if I just gently press the power button a few times once I turn it on.
Also have you tried a "hard reset"? Basically you hold the power button down for 20-30 seconds until the kindle turns completely off.
Barring this I am drawing a blank. I am only just now learning the ins and out of this system.

If it won't charge on its own, you're probably going to have to make/buy a factory cable and try it this way...

Good luck.
EDIT: You might actually be able to do the above without a factory cable since you have FFF installed. This is all just "in theory" to me because I've never encountered this exact problem.

Try this:
Unplug your device
Get your command prompt ready (make sure you are in the directory that fastboot is located)
Type the following command ( but don't hit enter yet):
fastboot -i 0x1949 oem idme bootmode 4000
Plug your USB cable into your computer first, then your device
When it comes on, within the first few seconds of seeing the yellow triangle, hit enter, then reboot.
Plug it into your charger.

Sounds like a problem I had, unfortunately it was because I had completely submerged my kindle in water on accident and the battery got fried. It would boot, I would see FFF then it would restart... gotten your kindle wet at all?

[Q] Help, please! KF turns on and off when plugged into usb :(

I used KFU to root my KF (with v6.3) and somewhere in downloading the twrp, something went wrong. The next thing was that it asked to press any key to continue; when I did, the cmd prompt disappeared. I disconnected the KF after some time which was the biggest mistake. When I plugged it back in, win 7 cannot recognize it anymore. I tried to install device drivers but it couldnt get through to the device. I ran the Kindle Unbrick Utility v1.1 and it also couldn't find the device. Now, when I plug it in the usb, Windows recognizes it as Kindle but it turns on and off so fast.
I would appreciate any help, please!! Thank you.

Your battery is probably dead and USB doesn't provide enough power. Plug it into the wall charger for a while then fix your drivers/bootmode etc.

Thanks for replying, soupmagnet
I am charging my KF now just to see how it behaves when it should be fully charged. It seems to turn itself off when I take out the charger even after a few minutes of charging. I'll give it a few hours... I'm already missing my KF (

Help me with my Dead nexus 4 (hibernation mode?)

Hello everyone.
3 days ago, I was charging my nexus 4, I checked and it was at 80%, and after a while, I rechecked it to find it dead : no boot, no charging icone, nothing. Even if im familiar with this problem (happened to me once before I replaced the battery), I tried different methods to resolve the issue : pressing volume down and power button and plugging charger or usb cable million times, letting the phone charges over night, charge it on computer, taking off the battery and trying to charge it seperatly (saw a thread on this forum), nothing happened, just a blinking red LED whenever I press volume down or up and power button over 10-15 sec and plug it. I even checked the battery with a multimeter and it emmites voltage, so I think the battery is good (1 and a half months old).
Please help me with this.
P.S: the charger used when the phone died was a faulty : if u touch it or expand (till tight) the wire, it stops charging, and u have the press the head tight so it goes back to function, and the one I used for testing all I said above was a good one.

No1 to provide any help? Come on XDA !

Did you try under volt using any kernels? I've heard this causes the issue not sure though
Sent from my Nexus 4 using XDA Free mobile app

No I didnt flash any new roms nor kernels, the phone runs stock android 5.0.1

May be the faulty charger caused it.. And if you are using charger other than the original make sure the output is same as the original, because I used Sony charger and it took ages to charge, so what I think is may be the charger you are using fails to provide enough out put to get it charged, if still no luck then service center is only option left

yes that's what Im thinking.. I dont own an original charger but I used a sony one that has a slight difference with the original LG one (in the Amps : Lg : 1.2A and Sony : 1.5A) but the phone is still dead :/ the repair store said that it needs flashing the stock rom --" Idk how --"

Is your PC able to detect it? Try the method of rebooting to fastboot (neglect if you screen is blank) and check if it detects flash factory firmwares
Sent from my Nexus 4 using XDA Free mobile app

for pc, I hear the "new device" sound and the LED turns red for abt 3 seconds or maybe 5 but its not detected and then the LED turns off, and if I plug the phone while holding the buttons volume and power, It also make the same thing and after that I hear the disconnect sound, and if I maintain the press I hear the disconnect sound every 10 sec or so with the LED blinking continuously.
How do I fastboot in this case? and IDK how to install the ADB things and get it to work, I did a lot of this on my XPERIA P but for the nexus I never did and I couldnt grasp well some of the explainations out there + It's meant to ppl with normal devices and not broken ones (enable debugging mode etc..)

For almost any device download minimal adb and fastboot, install drivers, connect the phone and type adb devices and check if it gets detected,if no then hold vol down and power button to boot into recovery and then type fastboot devices and check if still not detected, right click in my computer and select manage devices and check if there is a device which is not installed then install it manually , and repeat adb and fastboot steps if still not detected then I can't help you

Nexus 7 Dead (as in, totally dead!)

Hey guys, I signed up here because I'm desperate for help!
To cut a long story short, I upgraded my N7 (wifi 2012 model) from 4.4.4 to 5.1.1 which was an awful idea as performance was through the floor. So I used the ADB tools to flash and downgrade back to a stock 4.4.4 image from the google repository.
Unfortunately, after flashing I tries to get to the recovery mode (was on the boot loader) and it said "error", wouldn't let me go any further and just kept me in the boot loader menu. I rebooted the device thinking it might have just needed a gentle shove, but it didn't reboot...it turned off after using the power off command.
Now when I "try" to turn the device on I get a black screen and nothing else. To confirm, this isn't the usual battery related "black screen" with grey static and the enabled backlight caused by long term discharge. The screen is totally black, no matter what key combination I use there is no visual response. The only time I can generally see any sign of life is when It's plugged into my laptop - windows plays the "new device detected" chime, but ADB can't see it and about 90% of the time windows states there was a device error. At this present moment the device is powered on (again, no visual sign) just a chime and an active driver showing in devmgmr for "Android ADB Interface".
ADB - Any attempt to use ADB fails and shows "no device found / connected", I've tried multiple solutions such as the nexus root kit but they all have the same issue, they just can't talk to the device. I know it's not the laptop at fault because it was detected fine multiple times prior to flashing it?
There is something alive in the device in terms of powering it off and off as holding the power+vol down button does do enough to trigger the windows chime to indicate it's powered on, but windows can't do anything with it at all. Note the device was 95% charged during the flash so it's not like it crashed mid way.
Any help would be appreciated, it'd be a shame to bin it
Thanks
Lawrence

Take the back off and disconnect the battery. Press the power button to discharge any leftover charge. Plug back in the battery, then try powering up in bootloader mode.

Hi Psiphi,
I did as you suggested, took the case off and disconnected the battery cable - pressed and held the power button in different combinations to make sure it discharges any remaining power.
Sadly, no change - any attempt to power it on results in the same lack of response
Anything else to try?
Thanks

You might try forcing a flash using the Nexus Root Toolkit, but otherwise I am out of ideas short of buying new hardware.

I agree use nexus toolkit, use the force flash mode... I recovered mine about 6 months ago it was dead... Nothing worked...
