I've got a Kindle Fire HD with stock FW that will not power on.
I've measured across all of the red wires on the battery connector to ground and I am getting 4.14vdc so I am assuming the battery is fine.
While 'charging' the KFHD, it is only pulling 1.8w/.03a from the wall.
With the back side off of the kindle the CPU area gets warm, but the battery doesn't
I've tried holding the power button down for 20-30 seconds and it still does nothing.
Would it be possible to pull the battery and cut and splice a usb cable and wire it directly to the battery port on the KFHD's mobo and attempt to power it on that way to make sure that the mobo is good? If anyone has had a similar issue please let me know.
Thanks in advance.
Sounds more like it's hard bricked, if it won't power on I'd most likely say the bootloader has something wrong with it. That can't exactly be fixed just her because we don't have the pin out of the emmc yet for the 7" HD model yet. If you can look it up there's a pin that if you from d it it would briefly show up as an omap device, if you can do that much at least then you could prove the motherboard works, but the omap device is useless because while on a kf1 we can use it to reflash the boot loader, on a kf2 we need a signed aboot that is signed by amazon to fix it.

Hey there. New around the Kindle Fire HD parts as I haven't actually received mine yet..
But, I was curious as to whether you guys could answer a question for me!
If you have your Kindle Fire HD turned off and then apply power to it through the USB, does it turn on? I mean on as boots into Android, not simply displays a charging screen of some sort.
Are you on Stock or the unlocked bootloader?
And lastly, I doubt anyone has tried this.. but I might as well ask! Has anyone tried to remove the battery from the Fire HD and turn it on using only power from USB?
Appreciate the answers.

Hey there as well. In answer to your questions...
1.) Yep. It does power on when you plug in USB. No charging screen, just the whole OS (unless there's not enough power to boot Android, in which case yes, there is a charging screen).
2.) I have the second bootloader installed, with Chameleon OS installed.
3.) As for opening up the Kindle.. that's a gray area for me. If I knew what I was doing, I'd open her up, but I don't know if I'd be able to get her back together. Lol
Hope this helped

When you say "unless there's not enough power to boot Android.." do you mean the battery needs some level of charge before the tablet turns on?
For instance, if I left the tablet on and drained it down to 1%, then plugged it in, would the tablet boot straight into Android or would I get a charge screen?

If you drained the battery (and some ROMs do that in a bad way), the Kindle will only show a charging screen (at least mine does). However, I can't remember if this was when I was on Stock OS or on a different ROM.
So yeah, it does seem to need some level of charge before Android will boot.

Awesome. Appreciate all of the info. I'll see if I can't set Tasker up to turn off the device when the power is removed. If that doesn't work, I'll go build my own version of Android that changes the battery shut off percentage to something high enough to make sure it will turn on as soon as power is applied.
Thanks again for all of the info!
I have an Amazon Kindle Fire HD 7 inch tablet. I tried to install cm10 and it would only boot about every four tries so I decided to go back to the Amazon OS. After I flashed it back with the srt tool, it now only boots with kindle fire logo for about four seconds and blinks the logo again in a bootloop. I bought a usb fastboot cable. I bout the n2a cable that was recommended in the forum but it still boots the same thing while plugged in. Am I out of options? Thanks in advance.
I forgot to mention it's the kindle 2012 version.

Hold the power button for 30 seconds until it powers off. Now plug the Factbook cord into the tablet and now you USB port. The tablet should energize into Factbook mode automatically.

Thanks for the reply. That's what I've tried to no avail. I've even removed the back and unplugged the battery to make sure it was off. It turns on to the kindle fire logo even still. I have the motorola/kindle fire fast boot cable. I would purchase scoprn's cable but I don't want to waste my money if it's not the cable. The fast boot cable I bought was used by others users in this forum successfully. It's weird though, everyone seems to suggest that if it boots and is showing something then it's not bricked. I just don't what my options are at this point.

I recomend the adapter by blackhat i think hashcode has posted in his 2nd bootloader thread, goes in between a normal cable and the plug on the kindle.

Thanks for the suggestion. That's the one I purchased over the weekend. Hope it works.
complete noob here looking for some help.
i have a kindle fire demo unit that i tried to run the utility program on using a factory cable.
the problem is that i did something wrong and now my kindle wont turn on and it is not seen by my pc.
can i fix this and get it working as a android tablet or is it now completely dead.
Shut it off completely by pushing the power button down for at least 20 seconds. Now plug in ur fastboot cable into the fire hd and connect it your computer. Does it get into fastboot mode? Do u remember how much your battery was charged before it stopped being detected on your computer? If it was less, you would have to look for a way to charge your battery first, as I don't think the device charges itself in fastboot mode. If you remember having plenty of battery and you are sure you have a kindle fire HD 7 2012 edition then look for a boot loader repair guide which we have on this part of the forum of the XDA. If you are capable of performing the mod, good, else find someone to do it for you.
Regards
I cannot seem to find any help with this one anywhere so I am starting a new thread.
Basically I have a Kindle Fire HD 7" Tate that shuts itself down after loading either the normal Kindle Fire boot logo OR when entering Fastboot. It stays on in Fastboot for about 3 seconds and then switches off and continues to loop while the factory cable is plugged in.
If I have the normal cable plugged in, boots to Kindle Fire screen (no animation) and then shuts down. Power button unresponsive.
Any ideas? I have managed to load the bootloader, recovery and boot stock via fastboot in time before it shuts down again but this has not helped.
I've requested that this be moved to Kindle Fire HD 7" Q and A

You might want to recharge the battery with normal USB cable.

Tried leaving it on charge overnight, still the same thing. It occasionally goes to red triangle in a boot loop so I don't think all is lost. I was wondering if it were possible to reflash the xloader partitions but I cant seem to find the file I need.
It seems that the battery is not charging. I managed to get the Kindle to stay on long enough for bootloader,boot and recovery to be flashed via fastboot but then the battery seemed to die mid way through flashing system. I am going to try and put the battery in another KFHD and charge it, see what happens.
Looks like I have found the problem, the power button board is faulty. The Kindle has suffered some water damage by the looks of it. Unplugged the connections to the headphone board and all is working and I am able to reflash via fastboot without it turning off
Has anyone been able to use a Kindle Fire motherboard through usb to PC?
My screen is broke, no replacement. The battery is disconnected aswell.
Just looking to see if it would be usable still with no screen.
Thanks!
