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?

I did that and im doing that now it does a never ending cycle the light turns green it turns on fire triangle that says press power for recovery then shuts off then does it again then shuts off over and over it did this all night it
doesnt respond to the power button the only time i get any type of response is when i plug it up to the outlet or usb cord on pc then it does the never ending loop like i explained
i tried the oem charger and another charger also tried another usb cord plugged to pc does the thing every time

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] kindle doesnt have enough power to boot

I'm using the factory charger but I have twrp.when I boot it it shows the triange then shuts down then back up in a loop, what should I do.I had the charger plugged in then the kf just died
Please help

I am seeing more and more of these threads of the kindle "not charging" after TWRP is installed. I am wondering if it's user error or something deeper.
I would let it charge for a bit and see what happens. Also press the power button a few times when you turn it on until the light turns orange. If it does turn orange and boots into TWRP then you know at least the kindle is not "bricked" and you can restore a backup.

Thanks but it won't charge at all I know its not charging because when it turns on a little later it shuts back down,then it boots up and shuts down even faster than last time.

Have you try to press and hold the Power button for more than 30 seconds?

I think I need to take the battery out and charge it separately,but how would I charge it once its out?I need help.

I have also used TWRP with Energy CM9 Kang ROM. In generally it is okay with a few non-major issues.

mad at myself
I am so mad right now...I got it working by making a charger that is one volt stronger.It booted up, but then i was going to take a picture of it to put on xda and when i plugged my charger in the seond time, the device shut down.NOW WHEN I CONNECT A CHARGER TO IT IT WONT EVEN TRY TO TURN ON,BUT IF I CLICK THE BUTTON IT TURNS ON FOR 2 SECONDS THEN TURNS OFF. I am so mad:

i assume you meant Ampere not Volt ?
usb charger has 5V - if build one with 6V (don't know how) - you will damage the device !
it should have ~2A - let it on the strong charger over night

I'm pretty sure that will work, if you can get that far. Otherwise (assuming you've already opened it) unplug the battery cable, start the fastboot command, plug in USB, then when (if? not sure it'll work) fastboot completes plug in the battery.
Changing the charging voltage won't help because the charge controller has a built in regulator. IIRC it will take something >12V, but there are probably other things on the USB V+ that might get fried at those levels.
I do remember from the tiny bit of battery charger documentation I'd seen that the Fire's charge controller does not have the flat battery recover feature, that is, provide a trickle charge by default if the battery is too low to power up the CPU. Which is flat out stupid on a consumer product.

[Q] Phone Not Turning Up

Hello all,
My phone is not working and I am not sure why. Last night, I was at about 30% battery and I was charging via usb from my computer. It was working fine. I later plugged it into the wall charger for the night and powered it off. This morning, I tried turning it on and it didn't boot up. I tried plugging into different chargers to make sure it is not the battery, but the phone didn't show the battery status when plugged in. This makes me believe it is a broken USB port. I already called google and initiated an RMA.
Has anyone had a similar problem or know how I can fix this?
Thanks.

Did it show a red blinking led light when you plugged it in? Also did you try hard reboot(hold power for 10sec). Or try getting into bootloader(hold power + vol down)?

When I plugged it in after discovering it wasn't turning on, it did not show a red blinking light. I tried a hard reboot with no response. I just got into the bootloader (with the power and vol down) and it turned on. Thank you for the help.
Is there anything I can do to avoid having this problem? Also, what would cause the phone to not boot up?
Thanks.

Were you using a custom kernel with UV capabilities? If not than I'm not entirely sure why this would happen. Do you normally shut your phone off and plug it in overnight? Try airplane mode at night maybe. Possibly something glitched while the phone was off and plugged in.

Interesting. I was running completely stock (no root or unlocked bootloader or anything). It might just be a bug. I'll try out the airplane mode next time. Thanks for the help.

[Q] Battery issue or bricked? full symptoms list

From what I've read, a bricked phone and the known battery issue seem to have very similar symptoms.
Long story short: I was running a benchmark and the phone turned off and would not turn back on, and there was no red charging indicator. I let it charge overnight and now I have a blinking red charging indicator and I can get into Bootloader and Recovery while plugged in to the stock charger (5V 1.2 amp), but not when plugged into the computer (5V 500mA). I tried restoring AND full wipe/ fresh install and it still won't boot. When plugged into the computer I can get to the bootloader for about half a second and it will turn off. Also I can get into "download mode" on either connection, and I did not have "USB Debugging" enabled when it first turned off. What is download mode and how do I use it?
What do you guys think?

I have the similar issue, I can't charge the battery, while charging there's about 3mins RED LED last(not flash), hold the three buttons, but just a black screen, no bootloader no download mode.

bootloader is power button + volume down

How? I can't get to fastboot while its hooked up to the computer. It will only go into the bootloader when its hooked to the stock charger.
