[Q] firefirefire bootloop problem can you help?

I have a Kindle Fire that I have successfully rooted and using CM7.
I let the battery completely discharge and since then the device has been stuck in what appears to be a boot loop at the fire fire screen (I have a video of the problem but because this is my first post I am not able to post links, you could find it by going to graham dot doel dot org forwardslash kindlefire)
It won't turn on unless a usb cable is plugged in. When the usb cable is plugged in the apparent loop starts.
This is what I have tried:
1. trying to charge the device.
2. trying a hard reboot. Holding the power button for 20 seconds, doesn't make any difference.
3. connecting via adb, the device isn't seen.
4. Making a factory cable and trying to connect via that, but no joy there, the device isn't detected by the computer (windows or linux)
Could anyone make any suggestions about how to unbrick this device, I have searched high and low and have found nothing that helps or works.
Thank you

the repeatent on/off is typical - what happens:
kf tries to start - battery breaks down - kf tries to start - battery ...
the only solution i know is to charge with the wall charger for some hours (over night)
but if you plug it to the wallcharger it turns on
so press and hold the power button till it turns off to allow the kf to charge

Thanks. Pressing the power button seems to have no effect what so ever. Do you have any other suggestions?

i meant to hold the button till it turns off -> ~30sec
that it is off when on the wall charger
don't know an other solution - worked for a lot of others

I have tried this. the power button doesn't respond. plugged in or not.

Hello !
Same problem for me ... I let the battery completely discharge and since then the device has been stuck in what appears to be a boot loop at the fire fire screen... I plugged it (in the wall) pressing and holding the power button till it turns off to allow the kf to charge but there nothing ie no orange/green light... Do you have an idea?

Same problem here...
Here is my thread http://forum.xda-developers.com/showthread.php?p=22685015

Since it is quite obvious to me the device will never work again due to this POS battery, does any one want to buy it for parts? Or can Amazon repair it, even though its rooted with a custom ROM and recovery?

I have found a solution!
The problem was a power problem. I tired a different more powerful charger and It gave me enough power to turn the unit off and let it charge up.
Hope that works for others.

just for information:
the original charger is 1.8A - you should use one with nearly this power
i use a 1A and it's working fine - nevertheless i think that is the minimum
please mark the subject of the topic (edit first post) with [Solved]

I have this exact same problem on my stock KF. Powers on with wall charger plugged in (no light green or red), immediately shuts down when unplugged. Been through all of the forums guides KFFB and the linked ones by Kinfauns I purchased a factory cable attempting to make it fast boot on computer, no power at all. Doesn't appear to have any effect

I am at my wits end . Is there some type of battery failure that would account for being on charger for hours and not keeping the charge? or since it does boot up would it still be the software not in fastboot to allow a charge??? I plug in the wall charger, press button until it shuts off, and left it for several hours ( one last time going to try longer than overnight)

Guys please help me

ok so i was surfing the web on my kindle fire wich is running android 4.0 and it just shut off. i have twrp and adb on my kindle and noow when i try to turn it on the blue kindle fre logo comes on for bout a sec and then disappears it doesnt help if i hold the button idk what to do i tried using kndle fire utility but the status is offline please help i love my kindle fire.

Yeah you have a flat battery most likely hold power button for a minute plug into your computer via usb for a few hours and leave it alone it should charge when mine went flat I was able to use stock wallcharger with same method and it charged but usb is recommended

ill try it

Kindle Fire Charging Infinite Boot Loop

I installed the AOSP JELLY BEAN 4.1.1_r1 (http://forum.xda-developers.com/showthread.php?t=1765288) the other day and it was working fine. The problem is, I used it too much and the battery died on me. Fine. So I plugged it in to my pc via usb to charge it up. The Kindle fire boots to the TWRP triangle and then instantly shuts off. Well I thought maybe the battery is just really drained so I left it plugged in and went to work. Got home and it was still doing the same thing; boots to the TWRP triangle and then instantly shoots off and repeats. I unplugged the usb and tried using the outlet charger; same thing. Disconnected and tried to turn it on and nothing happens.
Figured I maybe bricked it somehow (even though i didnt update, delete, wipe anything). So I tried using the unbrick command lines...nothing. Tried the KFU cant find my device since it shuts off every 2secs.
I cannot figure out whats going on. Any help is appreciated. Thanks

Plug it into the charger and hold down the power button until it shuts off. Then wait for a 2-4 and check back on it.
Once it boots back normally make sure to update FFF and TWRP.

That didn't work. I plugged it in with the ac adapter and it wouldn't allow me to turn it off (i plugged it in then tried to turn it off). I let it sit for 8hrs and still boots up to the TWRP logo and instantly turns off and wont even turn on without it being plugged in. Thanks

Hold the power button down for 1 min it should shut off

it still does not work
Please post here some detailed instructions to turn on this device.
I'm tired of holding on and buttons in different combinations.
Sorry for bad English

If you have fff 1.4 a there really is no magic combination just simply power it off and plug it in via usb to your computer. If you do not have fff 1.4a then look here http://forum.xda-developers.com/showthread.php?t=1623244

Did u leave it to charge overnight.. cos i also had the same problem, which i primarily due to low battery charge..

bricked kindle??!!

Ok so i rooted my kindle and flashed energy rom with twrp. They were both outdated. So i was about to update them but my battery ran out. So i let it charge and it kept showing the twrp logo and kept looping in other words it was in a recovery loop. I can't acces recovery or abd i think fastboot works but im not sure i tried this http://forum.xda-developers.com/showthread.php?t=1428428 but it still doesnt work please help.:crying:

Try soupkit.

Forgive me if this sounds like an obvious question, but could you describe the "twrp" logo you are seeing?

See? There's no such thing as a stupid question.
Actually that is the FireFireFire splash screen. And I'm guessing that the "boot loop" you are experiencing is more like the FireFireFire splash screen flashing on and off?
Your device must to be able to boot so far before it can charge properly. It's kind of a screwed up situation but there is a way around it.
Every time you hold the power button to force the device to shut down, it performs a series of tasks before letting go. One of these I'm guessing is to enable charging over usb. The best way to do this is to plug the device in and immediately hold the power button until it shuts off, and stays off. Leave it alone for a while and it will charge properly.

omg ty couldnt find the awnser to this ty so much. ill let u know i it works

Not working. it reboots in 5 secs

Let it sit for a while (probably overnight) and try again. Unfortunately, short of replacing the battery, that is probably your best option.

Screen won't turn on, battery indicator light works

I recently installed Alien Droid for kf2 on my kf2 and everything was going smoothly so I doubt it was that, but I woke up this morning to a kindle fire that wouldn't turn on at all, the screen doesn't flash or anything and it just stays blank. I've done the hard reset where you hold power button for 20 seconds and still nothing. The battery indicator light comes on when I plug it in and it will turn off when I do the hard rest. Could this have anything to do with maybe the battery dying overnight?

While it's plugged in to the computer (given time to boot normally), are you able to communicate with the device via adb?

Nope, I've also left it to charge for about six hours. Now when I try to press power button it flashes green but the screen does nothing

I would suggest checking to see if it can be detected by Linux (lsusb). If not, your last available option may be to try and usbboot. I can't imagine what would cause the device to act such a way, but guess it's still remotely possible that the bootloader or bootloader partition got corrupted.
Hopefully, you're not looking at a bad eMMC.

I have a suggestion that your kindle has a bsod (black screen of death) hold the power button for 20 sec. and then press it another 3 sec. hopfuly i am right and your kindle will turn on. have this bsods 1-2 times per day.

It absolutely sounds out of power.
I know when my kindle isn't charged the light blinks like that. Maybe if the above suggestions don't work.. Try another charger

I just realized you have a kf2 and not a kf1, so usbboot is obviously not an option for you. Disregard my previous statement.
You' already tried the hard shutdown and you say you've let it charge, but have you tried letting it charge while completely powered down?
Outside of that, I wish I had a better suggestion for you. It's definitely an odd situation.
