Does anybody know how I might be able to go about testing what component may have failed on my Fire HDX 8.9" 3rd gen? I was using it last Friday in the morning and noticed it was a little sluggish, so I held the power button and turned it off the normal way to clear the cache. I plugged it into the original charger that I've always used, but when I came back to it, it wouldn't turn on. The device was only around 62% battery life when I turned it off, too. My device isn't rooted and is running the standard fire OS. I opened it up and tested the battery with my multimeter and got a reading of around 3.8V so I'm not entirely convinced the battery is the problem. When I've tried various combinations of extended presses of the power and volume buttons, it still hasn't responded; nor is it being recognized when I plug it into my computer. Is there a way to test if it's a bad power connector or if one of the boards might have fried? I'd hate to lose this thing seeing as I've had it for the last 6 years and would like it to continue to accompany me on work trips.
I love the HDX for its computing power and screen so much, I decided to upgrade to the 4th gen, even though it's still 6 years old. Ironically, the day that my 3rd gen bricked is the same day that my "new" 4th gen arrived... Maybe it was jealous?? Lol.

Looks like it was the motherboard. I purchased a used 16gb HDX 8.9" 3rd gen and swapped the boards. Next thing I know, my kindle works and the rest one didn't. I just wish I could recover the old one so I can increase my storage capacity. Too bad there's only one motherboard listed on ebay and its a 16gb as well...

I have a Kindle Fire HDX 7" that I purchased a couple of months ago for my son. It was rooted and running Thor with Gapps. He plugged it in before going to bed and when we looked at it the next morning it had the Google X showing. We unplugged it and now it will not power up unless it is plugged into a wall charger. It will boot into safestrap, but bootloop before it gets into an OS. I bought a ChargeDR to up the power output on the USB, but as soon as I try to switch to sync it will turn off again. My theory was that if we could get it to fastboot with sync on then we could ADB, but that is out. Not sure if there is any way to salvage this one or not. What is odd is that safestrap still thinks it has 67% battery, but calibration must be off, which is why this happened to begin with.

If I read you correctly, you are assuming that you have not developed a hardware problem, but that the software is preventing the battery from charging. That seems highly unlikely.
Sorry for the confusion, I would say there appears to be a hardware issue as well. I am concerned that since it has safestrap installed that if I were to return it to Amazon for repair it would not be covered. Without being able to access it from a computer, I cannot remove safestrap. I have thought about force charging the battery by opening up the case, but it sounds like a complete disassemble would be in order. I cannot find any information about other occurrences of this problem.

Not to worry. If it's still under warranty, tell them it's broken and they'll send you a new one. They don't ask about the software you may or may not have installed.
Thanks. It should be under warranty, it is nice to hear Amazon isn't taking such a hard stance on development for these devices.
It was on 4.5.3. I used this thread to roll it back to 3.2.8 and was successful. It booted up fine.
So I open the browser and go back to XDA The next step is to updated to 4.5.2. The battery is at about 70% at this point. Before I do anything else, my son asks me to play catch with him, so I set it down and I go out for about an hour.
I come back and the kindle is dead. Won't even begin to turn on or make any noises.
I tried holding the power button for 30 seconds, tried holding the volume buttons and then power, charging it for a while, nothing makes any difference. And it's out of warranty.
Anyone have any suggestions? Wife is gonna be pissed that I broker her tablet, lol.
Try charging it for a long time. Make sure your charger is working.

Thanks for the suggestion.
It's spend the last few hours on a working 2A charger.
Still no life.
Crap.

This seems to be the recent fate for many who have rolled back to 3.2.8 and not blocked OTA using HDX Toolkit or an equivalent blocker (renaming otacerts is not reliable). It appears Amazon attempts to push an update that ultimately corrupts the boot partition. Not much you can do to fix it with current techniques/exploits.
If the device is still under warranty Amazon will likely replace it. Just say it died during an update.
That does make sense. Unfortunately it is not under warranty. Guess it's time to get a new tablet. Seems I can't even recover what's on this one.
Hi. Please forgive me if the answer's out there and I've missed it. I've been looking but don't see an answer to my problem.
My unrooted Kindle HDX 8.9 was on whatever the newest software was as of two weeks ago. One day it was fine, the next it wouldn't start up. I can get it to boot into recovery occasionally. I tried factory resetting it from recovery. It said "erasing" then rebooted and said it was updating, then nothing. The screen turned off and nothing else happened.
Sometimes it will power on and the first two kindle screens will appear then it goes black and nothing else happens. I can still get it into recovery sometimes. Mostly it just says "kindle" for a few seconds then goes black.
Is there a way for me to reinstall/flash stock kindle software?

As you probably gathered there is no easy answer to your problem. It has characteristics of a power problem (bad battery) where the device will only run for a few min/sec before shutting down. It could also be overheating. I would engage Amazon if the device is still under warranty.

Interesting, thanks for your input. I was actually wondering about the battery but wasn't convinced that was the problem.
It was at 60% battery the night before the issue, and then next morning I plugged it in. I took a shower, got out, the battery icon said 100%, and then it just stopped working. It wouldn't connect to wifi, so I shut it down to restart it. When I restarted it, nothing happened. I tried to restart it several times. It would occasionally boot to the first "kindle" screen then go black. After that, it ran down, I assume because of rebooting/hanging on one screen and then no battery icon would appear when it was plugged in. After a few days, I plugged it in and a big red battery did appear on the screen.
This stupid device was ONE WEEK out of warranty and Amazon would do nothing but offer me $20 off a new $400 Kindle. Fool me once, Amazon... Luckily, I bought the kindle with my Mastercard and they have an extended warranty policy. They sent me a check for the cost of replacing the Kindle and I bought an Ipad. Eff Amazon. I'll never buy anything from those jerks again.
I still have the Kindle but am no longer invested in trying to fix it. Maybe someone will give me a few bucks for it on ebay. It's in perfect condition other than the not working thing. Never been dropped, rarely left my house, no kids, no smoke or pets, etc. I'm pretty pissed at Amazon. There are 20 or so HDX reviews in the last month that say almost the same thing.

Agree with the shoddy treatment from Amazon. Although technically out of warranty (by a week!) one would hope for more than 5% off retail. Enjoy your ipad.
I bought a 7" HDX on ebay a few weeks ago , got it running on the Fire Nexus ROM, and love it.
So, an 8.9" came up on ebay for cheap money, dead, and I took a gamble on it. It looks physically fine. I charged it and nothing happened. Tried resetting, etc. Nada. Took it apart and confirmed the battery HAS a good charge ( 4.3v) .
What else can I do? The seller said it had been working but quit. ("The battery stopped holding a charge.. We do not remember all the specifics.") No signs of violence - screen looks good. Should I be looking for another motherboard or could there be any other thing I can try?

- tether device to known good power brick/supply (not USB port)
- long press power button for increasingly long periods up to 5 min
- if no signs of life you'll likely need a replacement main -and- daughter board
- trouble with those is you don't know condition; could be dead as well
- not an easy job due to the use of copious glue during original assembly
I connected it to a working Kindle (5 amp) charger and held the button for 5 minutes. Nothing. The battery holds voltage so....
It was my impression that the 8.9 isn't so glued up as the 7. But I will need to find parts and probably don't want to put loads of money into this.

Correct on HDX 7 vs 8.9 disassembly; there is more wiggle room in the latter for gently prying components to release the glue. Downside is larger panel is easier to damage given no additional reinforcement. It's possible the power button has become disconnected although that should have been revealed when the device was tethered (assuming hot line) as it will initiate a boot sequence. Might be worth openning as a check for physical damage that is easily repaired.
Any good news with yours?
My Fire HDX 8.9 suddenly stopped working today while charging. I opened it up, both batteries have 4.33 volt just like yours. I tried all the power/volume button combinations, but none worked.
Good news? No, and it gets worse.
I bought another on eBay that "was working fine until the battery ballooned".
Sure enough, it came and the battery was toast. It was impossible to remove the battery, so I swapped the second motherboard into my first unit with a known good battery.
No joy.
Swapped daughter board. Nothing. Swapped power buttons. Nothing. Swapped displays. Nothing.
So....I guess I have had it...will the third motherboard be the charm?
The screen on my Kindle Fire HDX 8.9 suddenly went blank while I was using it. The battery was not very low. I tried pressing the power button for 20, 30 and 50 seconds but nothing. I connected it to a PC but did not detect anything. I thought the battery died, so I bought a new one and installed it but no luck. My Kindle just won't power on anymore. I don't hear any sound either which makes me hesitant to buy a new replacement screen.
Is there a way to fix it? Which component(s) could be dead? Or is it designed to fail after a number of years ? I thought only the screen and/or battery could die with age. My Kindle is 6 years old, but I have been taking care of it.
Thanks.

Likely a component on the main or daughter board took a dump. Not much you can do about that aside from replace and hope. Probably more cost effective to grab a lightly used one off eBay or another auction site.
