Dead Kindle. Does not charge or turn on. Will not connect to pc.

I have searched and searched for three nights already. I actually opened the kindle in fustrsation hoping it was only a lose cable or something. No luck. My kindle was running ICS and one night it turned off. I plugged it in the charger and called it a night. In the morning I turned it back on but no go. And its been like that ever since. I have no idea how to get it to connect to my laptop. I tried everything and anything I found here and elsewhere online. Everyone says to connect or put on boot mode or something. But I have no idea if the kindle is even on or not. It just has a blank screen and thats it. I tried using the various tools such as kindle unblock utility and kindle utility but there useless since I can't connect the kindle cause i don't know if its on or not. Then I tried loading the drivers that came with unbrick utility but it says something about driver is unsigned. Scoured the web for an answer to THAT dilemma and nobody has a real solution. Seems every solution starts with, "connect device in fasboot or slow boot or snail boot" but the whole point of seeking a solution as far as Im concerned is cause the device DOES NOT CONNECT OR CANT CONECT TO ANYTHING!!!! Im at my wits end. Its three in the morning and my wife is on her 5th dream...again this week!!!! Please help!!! Im willing to ship this POS out to anyone that can fix it and I will donate a g2X rooted and unlocked for your time!!!! I swear I will!!! I just want to get this over with. PLEASE HEKP!!!!!!!!!!!!!
you need to use firekit.
it allows you to boot your pc of a linux usb live pen drive with some tools preloaded.
all you need is to shortout a contact inside kindle and insert usb cable into kindle at the same time.
ill post a link in a minute. just follow the instructions exactly and i'm sure it will bring your kindle back to life.
hope this helps

I was in the same situation as you were, i messed up my KF but was able to revive it using the USB Firekit (link in the first reply you got), just follow it carefully. This will require you to open up your KF.
Dont despair, it will work
if you have probs with firekit.
post as much detail as pos of what you've done and where you're at in the process.
its not too hard as long as you follow the post to the T.
let us know how you get on.
cheers

do you know what 3.0 kernel version you had installed. if it was #10 or lower follow the instructions below. my kf did the same thing and it's any easy fix. most likely your kf's battery is completely utterly dead.
NOTE: this may or may not work depending on what the kfu or unbrick utility did without you knowing.
1. plug your kf into the wall charger.
2. press and hold the power button until the light comes on. if this happens it will boot to a black blank screen but you will notice the backlight is on. let it sit this way overnight.
3. after it has sat overnight, unplug it from the charger and hold the power button until it powers off (light will go off as well ass back light lcd)
4. hold the power button until it comes back on. let it fully boot. you'll notice the time and date are incorrect.
5. power off again
6. download hashcodes newest 3.0 kernel #12
7. power back on and boot into recovery.
8. flash the newest kernel you downloaded
9. wipe dalvik and cache
10. reboot normally.
you'll then need to reset the date and time and you shouldnt have any problems after that.

I have it working now. But one issue. The Kindle boots up normally now first into FFF then to android. Everything seems to be working fine except my battery shows 0% charge all the time. It does not charge. I unplug it and immediately shuts down. Anyone know what I can do to fix this? By the way, thanks for everyone who helped or contributed some input. By the way if anyone wants to know the method that work led was the Firekit method using Ubuntu Linux and the short test trick. I tried it several times even had some help on Teamviewer from a very helpful member. But after trying as few commands, it finally booted to the yellow triangle and after that I went to recovery and reinstalled CM9. So yeah everything seems to work now except the battery basically acts like its not even there.

Just flash FFF 1.4a, plug it into a USB Port on your computer, and take a nap. It should charge enough that you can reboot into your system and let you continue charging it normally.

KFU is for the original kindle fire. Go post your problem in the KF2/KFHD QA. Most likely you have bricked your kindle. And factory cables don't work on that kf.
Whew. Didn't have to do anything elaborate on mine. Someone unplugged the wall wart and I didn't notice it for a few days. Held the power button for a minute or so as suggested above. Then tried a normal power on. That worked :good: Now I have it sitting in TWRP at 1%. When it gets over 10% I'll reboot into the OS.
THANK YOU!

[Q] Desire does simply nothing

Hi @ all,
I have a big problem with my Desire.
I rooted it and installed AOKP Build 39 on it. Everything went fine, no problem up to this time. I did several restarts, everything ok.
Now, today the phone suddenly turned black, no reaction to any command. So I pulled the battery, put it back again, and then, nothing happened.
My desire only shows a black screen, none of the buttons are working (even Vol- + Power or trackball+Power). Even more suspicious is, that the loading LED is not showing up, although my phone is connected to the loading cable.
I really don´t know what to do. Does anybody of you have an idea what the problem could be?
PS: right now ist started vibrating (endlessly...)

I think that you can begin with construction bussiness, cause you have a nice and expensive brick...
Sent from my HTC Desire via flashes and thunders
Trackball + power isn't supposed to do anything, back button + power is.
But anyway if volume button + power doesn't work and that one neither, I think it's a brick as nlooooo said. Also because the LED isn't working. What does it do when connected to PC? Nothing I assume?
Yes, unfortunately connecting it to the PC does nothing.
What do you think, any chance to get it replaced?
if its still under warranty then u could chance sending it back to htc, just say u tried turning it on in the morning and... nothing just black screen. do NOT say anything bout s-off etc etc. im mean if ya cant even access hboot or no led lights or anything how will they know mite aswell try
dont forget take out ur sdcard incase they look at it n find a rom lol

No battery is not the problem. The same thing with another battery.
I´m still in waranty period, so I´ll have a try
Thanks for your help.
Can anybody imagine why this happend? I mean the rom was working proberly, no errors during flashing, etc. And can a faulty rom/flash cause a fail of even the loading led?
I always thought that such "simple" things as loading are done directly by the hardware without any influence of the software installed on the phone (especially as loading has to work even if the phone is switche offline)

I think it's a big hardware prob. Can u boot into android, even if the screen's dead? Maybe u can provide the devs with a logcat.
Our G7 can be troublesome sometimes......
Maybe it´s a problem of the mainboard. As i cannot even switch on the phone. when I press the power button nothing happens. So, no logfiles.
I´ll send it to the producer tomorrow.
Did you get it fixed?

[Q] KF2 battery problem after CM10 install

Hi, new here but I've been lurking for a while.
I followed Powerpoint's guide to instal CM10 on my KF2
http://forum.xda-developers.com/showthread.php?t=2105077
Everything was running great and has been since I first loaded version 3 a few weeks ago, and last week i went to version 4 of powerpoint's rom with no problems. Then a couple days ago after i had been browsing the internet on it for maybe 30 minutes, I set it down and when i came back the screen was off and wouldn't turn back on. so i figured the battery was just dead, so i plugged it in to the wall charger. At first the charge/power light wouldn't come on at all. Then after several plugs and unplugs the orange light started to come on but would only stay illuminated for 30 seconds-ish. So I tried it on my phone charger and the orange light came on and stayed on, so i decided to let it charge overnight. The next morning the light was still glowing orange so I unplugged it and tried turning it on, but still nothing happens. But when I plugged it back in afterwards the light came on green. now it has been plugged in for almost a day with the green light on but it still wont turn on.
Anyone else have this problem? Any ideas what i can try? for obvious reasons i can't exactly ship it back to amazon lol
p.s. I have a final on friday and the text book for that class is on the kindle. So urgent responses will be greatly appreciated.
Nevermind guys, I figured it out. Power button for 20 and it booted right up

I've had this a couple of times on both 10.1 ROMs. As you stated the only way I got it working was to hold the power button for 20 secs, then power on normally.

It just happened to me again, seems to be a recurring problem. Anyone have a clue what's causing this?
on a side note, perhaps this problem could be dealt with simply by installing a battery management app like juicedeffender. any thoughts?

Wow, for once I can completely and knowledgeably help with almost no guess work!
The issue is Sleep of Death.
The cause is unknown, and due to the nature of how to reset it, it's been difficult to get logs. It happened to FMK not too long ago and last I heard he was going to get the logs (to find what causes this) and get those to Hashcode to look at potential fixes.
It's not battery related....well in the sense that, if it happened, you reset the device, and looked at the battery, it should be at a similar level to what it was before.
TO FIX
You guys were right on fixing it mostly.
If you ever press power a few times and it won't turn it, don't bother fretting about it. Just do the hard reset, which is holding the button down for 10 seconds. After you do that the device will reset to the point where if you just press the power button once, it will boot up like normal.
I would hold it down for about 15 seconds just in case, or if you have headphones it, you can here when it does the reset and can get used to the timing.
I would say....in a few weeks with the device, I've had the issue around 5-6 times.
I've also NEVER had it happen while I'm doing things, so it hasn't caused issues besides making me a wait a bit before using the device, which is good. If it happened during doing things I would want this fixed ASAP, but so far, no major issues.
agreed, if it was happening while i was trying to do stuff it would be problem. As it is though, I just consider it a minor inconvenience. Glad to know I'm not the only one experiencing this though.

I wouldn't call it a fix. I would call that a workaround. We need a fix, and I think if anyone could get an effing log to hashcode of it happening, we could fix the problem. I think it is a kernel problem, what with the recent merges and such. I think something is incorrectly copying from kf1 to kf2... if anyone understands what I'm trying to say, it makes sense..

I wonder if pulling the log cat via adb would work, I.e. wait till it goes wrong' then connect it to a PC to pull the log. The issue is its very random and being at a PC to do it when it goes wrong could be tricky.

[Q] Galaxy nexus wont boot

Hello ,
yesterday my troubles with my Gnex started , my power button stopped responding (only a small percentage of times it worked) which meant unlocking/locking my phone was hard. Today the problems got worst I am not able to start my phone at all anymore. I've tried multiple solutions shown on the internet for example the solution of taking out the battery , plugging my phone into my pc and then putting in the battery and turning it on.
Does anyone have any solutions to this problem.
Hope someone can help me ,
Thanks in advance Dendroo
