This worked temporarily, but by the time we got fff and twrp on my device, the battery went completely dead. It would not power the device, and a replacement had to be bought. I do not recommend using this guide unless you have absolutely no other choice.
PLEASE READ EVERYTHING.
This a guide for how to charge your Kindle Fire's battery if you are stuck with the 5 second bootloop and you have tried everything else This is a last resort, and it works by charging the battery DIRECTLY. I recommend reading all instructions before starting.
"tried everything else" meaning:
- Trying to charge for hours using stock Kindle Fire Charger.
- Same with a non-stock 5v charger with at least 1.8 amps (Not counting ipod/ipad chargers, as I've heard they have compatibility issues with the KF. If you have nothing else, try it anyways.)
- Any other method you may have read about.
This WILL void your warranty (which happened a long time ago for most of you, anyways), and I am not to be held responsible for anything that may go wrong when following the instructions posted here. It worked for me! But it is dangerous and I cannot guarantee that this method will work for you.
PROCEED AT YOUR OWN RISK
Now that you understand the risks involved, let's get started.
1. Remove the back from your Kindle. For assistance:
http://www.youtube.com/watch?v=IQ6xxveRJSw
Other various guides are available online. Google search is your friend.
2. Locate the large battery connector (it should have three red wires, a yellow, a blue, a white, and four blacks) and pull it from where it plugs into the board. See 4:35 in the video posted in step one.
3. Now, get the 5v, 1.8+A charger*** you tried (and failed) to charge your kindle with. NOTE: I used a 2.0A charger, which worked fine for me. Normally, higher rates than what's recommended shouldn't be an issue, but I'm not sure that this is still the case as we're charging the battery directly. Cut off the end that plugs into the device (the micro USB end. I recommend leaving enough length on the end so that you may reattach it to the charger cable if you need to). Cut open the case of the cable, being careful to not cut through the inner cables/wires. You need these! There should be one black and one red; these are the only two you need. Strip them. Now, separate one single strand from the rest for both black and red. tape off the remainders using electrical tape. You may also just cut off the extra strands, but you may regret doing so if the flimsy single strand you're using breaks and you have to start all over again with the wire.
4. You should have a 5V, 1.8+A charger with the end cut off, the black and red wires stripped, and only one strand of each exposed. NOW. Make sure your charger is not yet plugged into the wall. Plug the single black strand into the far left black port on the battery's connector (this is when viewing the kindle from the back, right side up. As shown in the the aforementioned video) and the single red strand into the far left red port on the battery connector. There are three reds; make sure you put this in the right one. When the cables are plugged in as securely as they can be and the two strands (black and red) are not touching. Double check this. Now, plug in the charger and wait. I left mine for about thirty minutes, reconnected the battery, and... POWER! Make sure to quickly connect a charger to the kindle fire via the standard charging port to let it finish charging; this just jump starts your battery. If you do not have another cable to charge your kindle with, strip the severed end of the charger and reconnect it where you initially cut it off. Make sure to cover the exposed ends with electrical tape. I do not know if it is safe to leave the device charging directly for an extended period of time. The thirty minutes was enough for me and I did not want to experiment any further than necessary.
I hope you found this helpful! Be careful and may your kindle live on!
*** When charging the battery directly, I'm assuming a 5v charger with less than 1.8A would also work, but I have not tested this. I assume you would just have to leave it charging directly a little longer to get it to a point where the battery can power the device on its own.
I`m glad you wrote this up many here make this epic fail with thier kindles and dont have the correct bootloader to rescue them from this situation. At the very least its better than nothing and then they can flash fff 1.4a and hopefully not deal with this issue again so thanks
I'm always thankful to find guides like this, so I'm glad to have an opportunity to give back and help others out a little bit.
Now that I have power, however, I'm having issues with the drivers. Oh, boy. I've tried re installing variations a million times, two different PC's, even tried the firekit multiple times (I was having this same issue before the battery died). Still stuck at fastboot... I don't think there's a single other thread I could read on here. Not sure what to do at this point, as the Kindle only shows up in the device manger under hidden devices (Unknown device!). I've read that letting the battery drain resets it so it'll show up as Kindle and you can try the drivers again, but I'm not letting my battery get that low again. Ugh, this is a pain. Rooting my kindle went fine, but of course, when I offer to help a friend with his, all hell breaks loose. And I'm going to have to buy him a new one if I can't fix it (I'm trying to get him to just take mine, but there is a single crack of significant size on the screen.
...Sorry, got really off topic for this thread.
This should be stickied. So many people making threads about the same thing. Lol.
Thank you and help?
First of all, thank you for your guide!!
I actually did this with my kindle fire HD because it was not charging at all despite everything I tried. Unfortunately for me, even the jump start did not allow my regular charger to charge the battery; however, I kept the leads on the battery for it to charge ~60% and it works just great. And if I charge it through that method again, it charges, and keeps charge perfectly...just refuses to charge via its own usb port.
This is where I need help. I need to figure out whether it really is a bad battery not charging or it's the machine's fault. I was wondering if someone can kindly measure the battery values with a volt meter? Now, I'm not asking anyone to void their warranty, but if you had the back case open for some reason, it would be wonderful to get some values - specifically the cable next to the 4 black ones (white on my KFHD 7)
Mine measured with battery into port & charger in: black (or gnd screw) - white: 2.20 v
with battery into port & charger out: black (or gnd screw) - white: 1.70 v
without battery into port & charger in: black (or gnd screw) - white: 4.20 v This suggests that the kindle should charge. But the fact that battery charges using the direct method suggests the battery is still good? This is where I need help . Thanks everyone!
please help..

All red's and Black's wires are same. They only put 4 black and 3 red wires to avoid short circuit.
You can choose one of them, just don't mix them.
Dead kf 5th gen
Is there a guide to charging battery this way for the Kindle fire 7" 5th generation?
There are 2 black, 2 white and 2 red wires for the battery connector. Which ones do I connect usb wires directly to?

Cm ROM. Teenager sleeping with kindle plugged in. Has had charging issue for a while. I have four kindle fires, two cm7, one ICS, and one jellybean.
There was a father who had done some soder work in the usb area for his kid he was worried at one point he had made it to hot but it turned out to be ok I will search through some threads to see if I can locate his maybe it will have some insight for you...

I'm not quite sure what that means exactly.
The reason I'm wondering about which ROM the affected Kindle is running, is because the ICS and JB ROMs have had a similar charging issues from the very beginning. The latest version of the kernel was released last night with the charging issue fixed. You may want to upgrade before attempting anything like soldering on your USB connection.
Hopefully it is just the known ROM issue, which has now been fixed. I had difficulty charging my KF because the USB connector was coming loose from the mb. I had a hardware engineer attempt to re-solder it but he was not successful. The connector is very small and it is very difficult to re-solder. If it is a loose USB port, and you can get it back to stock, Amazon will replace it under warranty.

Go with the used board, but be sure that they match in serial number. The earliest releases of Kindle Fires used a different motherboad connector for the LCD, and are incompatible (found out the hard way). A good case opening kit helps keep from damaging the unit.
Motherboards are very hard to come by...
In that case, buy a unit with a broken screen on ebay. Make sure it's one that still powers on and charges (many will show the lcd working below the screen. More expensive, but you can keep the battery as a spare as well.

Not sure how to identify board revision on ebay?
Ask for revision number and/or serial number and make sure that they match. Even better, get a picture of the board so that you can see they are the same.

If it is just a kindle with a broken screen someone is trying to sell, they probably arn't willing to crack it open just to check the motherboard.
Don't buy without proper info. Buyer protection only works so well.

Thanks for all the replies.
It looks like if I had a nice hot air rework station I could repair it in just a few minutes. Right now just prying on charger connection to continue charging. I may just wait for it to die completely, afraid I will kill it with soldering iron.
if you make a TWRP backup and copy it to the computer, if/when you replace the motherboard (getting cheaper as the new Kindle Fire rolls out), you can copy this bac kup folder back to the new motherboard and restore. I have done this when I get a solid working JB ROM on a system, just so that I can go back to fresh quickly and easily. Also, suggest that you use Kindle Nullifire on any board bought from anywhere, as it will zero-write the internal sd card, and avoid issues more issues than you would imagine. It's worth the extra 10-15 minutes to do so.
Of Kindles and Chargers and Broken USB Ports
Kindle Battery:
Most of the inside of your Kindle is a huge battery. It requires a ‘hefty’ charger to charge it and keep it healthy.
Chargers:
While the Kindle Fire calls out for a 1.8 amp charger, I would recommend a 2.0 amp charger for the Kindle. iPad 2 chargers, 2.0 or 2.1 amp rating, with USB ports can be used with appropriate USB micro charging cables to work really well.
Many chargers are over rated and many have cheap thin wire that cannot deliver enough amperage to the kindle port and it will not "shift" into charge mode.
A Kindle will pull about 700mA from a charger, and the charger rating printing is mostly marketing and most of them do not deliver that wattage on a constant sustained level.
Charger/USB charger cable thickness:
If using USB to USB micro data cable make sure it is a thick wire cable that can push out the current from charger to kindle. Thin charger cables are conduits of squished electron flow and will not “shift into gear” the Kindle into charging mode.
Helpful hint:
If charger is not working, power down kindle and try:
Unplug charger.
Power off kindle
Plug in charger
Kindle should wake up in "charge mode"
Having fixed many Kindles lately, I am seeing charger issues, and plugging and replugging the USB cable in cause 50% of broken USB port problems.
Hope these hints will help.

Trying to give new life to a friend's Kindle fire, but it seems to have a weird problem and she has no idea why. I've looked through the forums and I have found several posts that are close, but not the same (and the solutions won't work either) because the KF will just shut down the minute a cable is plugged in.
Here's the array of responses for the various attempts:
The device will charge if it is plugged in (USB cable and AC charger) but no light comes on at all under any circumstance. And it will shut down when plugged in to charge, and will not power up if on the charger. If it is just powering up and you plug it into the charger, the light stays on for a few seconds and the first screen that just says "Kindle Fire" shows up, then it shuts down.
The device will boot if no USB cable is inserted. The device will shut down when you insert a USB cable. The device will not boot with the cable plugged in (AC adapter or computer) and the power button never goes green. With a usb cable plugged into a computer, the computer will not recognize the device (and it shuts down immediately upon the cable being plugged in to the Kindle.) Also, if you just power it up, then plug it into the computer (just like with the power supply above) the light stays on for a few seconds and the first screen that just says "Kindle Fire" shows up, then it shuts down.
When I received it, I noticed that the case had been opened (or at least pried on.) Also, the USB connector was loose. I removed the board, re-soldered the connector (it appears to be intact now, but the connections are TINY so there is a limit to what I'm sure of) and reinstalled the board. Behaves the same way. I performed a 'power button' reset to the device and there was no change. I performed a factory reset and there was no change to the behavior.
Next I purchased the N2A fastboot cable thinking that would allow me to boot the thing and force a real reset (and install a non-kindle version of android), but I went through everything again and there is no change in how it reacts. The moment that USB cable gets plugged into the kindle, it shuts down. I think I followed the instructions properly (they aren't that complicated) but I'm having no success.
I've reset it a couple of different ways and several times with no change.
Any suggestions?
My goal is to get this thing working, install a 'non-kindle' version of android and get it back to her to use as an inexpensive tablet and e-reader, just not tied to Amazon (or BN).

Thank you for the reply!
I'd agree that it could have a hardware component. I don't think it's fatal though since 1) it charges, 2) it powers up and works, 3) the wifi works.
I'd guess that it has something to do with the USB (to serial?) hardware but I don't know where to look on the board (other than tracing the traces but it's a multi layer board....)
I'm comfortable working (or rather 're-working') surface mount components. I have not see any interior/board layout info so I'd have no idea which chips to be looking at or testing.
Any suggestions about what area might be affected or pointers to schematic designs?
Thanks again,
Grant

Grant you could attempt usb boot it acts different than any other form of booting the device and may actually fix what is broken do a Soupkit setup, and run usb fix parts install fff and twrp.
There is at least the potential that it could travel the course less traveled and rebuild partitions that may or may not be broken.
Soupkit is here http://forum.xda-developers.com/showthread.php?t=1850038 and you will use one of it`s components firekit.
Rather than attempting to do a physical repair to the board because the components are very small and packed so tightly together.
It`s a medium to high risk approach but if you desire it could lead to benefit.
Truthfully IMO some things are better left alone.

I think that is a good plan and I very much appreciate the advice.
The fire is nearly useless to her in the present state and she was going to 'toss it' when I suggested the alternative. So, at the very least it's an education for me, and at the very best I'm able to resolve the issue, learn something and get her a working tablet in the end.
If I can get it acting 'normally' that would tell me a lot.
I have a spare 8G thumb drive so I suspect I'm in good shape for tackling this and it will be an interesting change to run linux on something other than a raspberry pi or a server....
Thank you again!

Ok, well...
I'm Korean, and I've searched almost every Korean tablet forums, yet can't find the reason :crying:
So I came to here, XDA.
The problem is, my Tab Pro 8.4 won't charge at all.
It's looks like an usual charging problem of Tab Pro 8.4, however, mine's little bit different.
With the charger plugged in and tablet is on, I can see the lighting shape on the battery icon at the status bar (which appears the charger is plugged in) ,
but no matter how long I charge the tablet, it's 0% and turn off after like...10 secs.
With the charger plugged in and tablet is off, I can see the battery pic appears on the middle of the black screen.
BUT, like the former situation, no matter how long I charge the tablet, I turn it on and it dies quickly.
SO, my problem is this, and i can't find a tiny reason why my tablet got (or how to fix) this battery problem.
Never seen a battery problem like I have right now.
I got several ideas about this. (Hope this will help you to fix my situation )
1. My tablet's rom is not pure. (But not rooted.)
As far as I remember, I applied the Ukrainian version about 3 weeks before.
Is it possible the this is the reason?
If so, wiping the original rom and applying the new one would help me?
2. Is it possible that the battery and the tablet connection got a problem?
If so, open it by myself and re-positioning the battery would help me?
3. The battery charger part might be damaged.
Then it leaves me the one option {GO TO THE SERVICE CENTER} ?
4. well...not 4.
have no idea.
Using same charger which is official SAMSUNG's.
I will keep monitoring this thread.
Little help to poor man would be really grateful, THX
PS
I just tested download mod.
With the charger is plugged in, it's working.
to see if the charger is bad, fully shut tablet down and then try to plug the tablet into a USB port on a computer and wait about 8 hours, then unplug it and see if the tablet holds any charge (battery might still be low but it should have enough charge to run awhile), if above works then it means you need another wall charger (5v 2.1A).
if it still just powers off or dies then it means the battery is bad or not connected or something else is wrong with it.
1. Try another USB cable
2. Try another 5v 2.1A wall charger
3. Try charging on a PC
4. replace battery.
To verify your tablet is charging, you need this little tool

Current should be 1.5 to 1.7 Amps, voltage should be 5 to 5.2 V
If the charging current is under 1.5 A, you should change different USB cable or adapter
If cable and adapter are fine, the next is charging port, it's easy to replace if your is defective.
Never use usb port on computer to charge, it only supply 0.5 A and your tablet needs at least 2 Amps for charging properly.
These are basic steps you need to do, without basic information I cannot tell what is wrong with your tablet: not charging or bad battery, or the worst: bad main board.
The one you have to verify: your tablet is drawing normal charging current around 1.5 to 1.7 Amps when plugged in. You can not troubleshoot problem just by guessing.
The most common problem of Samsung tablets are cracked Battery connector, a simple re-solder will fix the charging problem.
There are many unknowns, you have to eliminate charger, usb cable, usb charging port as the source of problem first. Then next look for battery or battery connector.
Otherwise, you will confuse yourself and others what causing the problem. Elimination is the key to figure out problem from many unknowns, one by one at a time. There's no short cut , otherwise, you can not figure out where the problem comes from.
I see many users send their tablets for service and the problem just comes from a bad cable because they have no idea what's wrong with their tablets.

You can charge from a computer fine just as long as the tablet is fully shutdown first (so you see the battery icon scrolling), this will ensure the 500ma will go directly to the battery and not running the tablet and os, it will charge very slowly but it will eventually reach 100% as nothing is drawing power from the battery to drain it (though I would only charge to 20%, to see if it holds a charge), however this method is just for diagnosing if the charger is bad and have no current alternatives, obviously this should not be a long term solution and never used when the tablet is running, but rather to see if the battery can hold any charge at all.
if you have another 5v 1+A charger laying around then use that instead., if the charger is the problem you can pick them up pretty cheap off ebay (make sure the hallmark icons and model number match to avoid knockoffs)

To see what is wrong with charging problem, you should never use wrong charger like 5V, 1 A or a USB port on computer. If using a 5V, 2A charger and a correct USB , any reading is under 1.5 A, there is something wrong with charger, or USB cable, or USB charging port, or battery connector. Even wrong USB cable, the one has only max of 1A, also is the source of slow charging.
His issue is not with slow charging, it was as soon as he unplugged it the tablet instantly powered off, in this case if the battery is 100% dead then damage is already done and once a lithium battery is completely discharged then most likely no charger whatever the mA is will bring it back...this is why I was saying to charge it from whatever source since you need to get a charge into the battery before it's irreversible damage.
However after re-reading ops post I think it's safe to rule out the charger as the problem because he said he could run the tablet with it plugged in (so that means the Charger is providing enough power to run the tablet) according to my mA reader this alone is around 500-700mA in standard use / full brightness
This also mean we can rule out a bad Micro USB port on the tablet since a broken one wouldn't allow power to the tablet.
the problem likely lies with a bad battery or a bad battery connection, the probably only option at this point would be for him to have samsung service it or take the chance to replace the battery.
(BTW I have all the tools nessasary and I know what can and can't charge this tablet)
Yes I know it needs a 2.1a charger to charge it while it's actively running since a good portion of that power will go into running the tablet and LCD if needed, it does not need a 2.1A charger when it is powered off and 500mA to 2.1mA will still charge it.
Three is a thread here talking about reseating the battery. Look it up. That may help.
Agree with otyg. I recently had a similar problem. My galaxy tab s 8.4 would power off immediately after being removed from power. It would register as having 100% charge while turned off, but once powered on, the tablet would show 4% charged or lower. Another thread on this site mentioned that the battery contacts on the motherboard have cracked for some owners creating symptoms like ours. I resolved the issue by applying a low resistance conductive adhesive to the cracked pins linking the battery to the motherboard. If this happens to be your problem be very careful because there are other contacts next to the battery pins. Good luck!
Hi everyone,
A few days ago, this problem started to show on my device.
When I'm charging it, it says "charging", but even the slightest movement can stop the phone from charging.
Sometimes it even toggles *charging*/*not charging* without me moving it at all.
For example, if the battery is on <15%, the phone will vibrate - so when I charge it when it's below 15%, if I touch it, it vibrates every 5 seconds or so.
It's really terrible... I once left the phone to charge for a few hours just to come back and find out it wasn't charging.
I've tried different USB cables, power sockets, chargers, so I guess it has to be a problem with my device.
I'm pretty confident it's a hardware issue, and I bought it around 10 month ago, so warranty should still be up. However, I don't remember anything particular that could damage the charging port, and this started all of a sudden (a day earlier it was charging perfectly).
I'd like to hear some opinions, solutions, and if any of you have had this before.
Thanks,
Barak
It's definitely the charging port, maybe it was faulty from factory, send it in warranty
Get a dress making pin or something tough and really pointy and carefully scratch inside the port. Be careful of the plastic inside. Do not bend it or snap it off. Do not scratch or pick at the pins on the top of the plastic. Only scratch around the plastic.
Shine a torch in and see if you can find any loose debris that you may have dislodged. Keep doing it until you can't get no more fluff etc out of it and try plugging the charger in again.
It should have a nice solid clunk as the plug goes in and seats properly now.
Hey, thanks alot for your replies. @shivadow I've tried cleaning the port like you said , this maybe helped a little but the problem is not solved.
P.S : I noticed that there is a position which is problematic.
When the phone is connected to the charger, if I hold the cable with my hand, and push it upwards (I exert force on the cable in a direction vertical to the screen). This is when it stops charging. Just stating this if it might help you diagnosing something specific.
Anyway I think I'll be sending it back to the lab this week or next week, thanks a lot for your help!
Either a faulty cable, plug or socket. If it happens with other cables it'll be the socket. If you know for a fact that the plug is seating correctly but you still have the problem then either worn pins or worn socket.
So it turns out that when I tried to check whether the charger, or the USB cable is to blame, I tried 2 different cables, but they were both faulty, which made me think the problem is with my HTC.
Now I tried changing phones and still had the same issue, so I tried more usb cables, and voila! Works like a charm
Thanks for the help @shivadow, much appreciated.
Always blame the cable first!
Hello there,
I got my Pixel 3a XL for a week now and since yesterday I'm not able to charge it with the original fast charger that came with it. With a different USB A To C cable it works, though very slow.
When I plug in the original charger one of the following happens:
- Nothing. I have to flip the cable like in the old USB days (wtf)
- It charges in a one second Interval. Meaning I hear the sound/vibration when it starts charging, but then it immediately stops charging, starts chargings, stops charging... and so on.
I already factory reset my phone, which didn't help. I tried a different charger from a galaxy phone. Same happens there. Only with a USB A to C cable which is plugged in a PC I am able to charge...
What could that be?

First of all, is this a new, used, or factory refurbished phone? If it's new or refurbished with a warranty, get it replaced under warranty. If it was used and/or has no warranty, look at the port on the phone to see if it's dirty. Carefully clean it out with whatever will fit in the port without damaging it. Pay special attention to the bottom as debris tends to get compressed and eventually gets thick enough to keep the cable from going in far enough to make a good, secure contact.

It's brand new. I did just clean it (but nothing came out or was visible) and now charging works again...
That's weird. It was clean as a whistle and I just thought "just clean it even though it looks clean"... weird!
But thanks anyway
Do you know anyone who has a QC 3.0 adapter and cable USB 3 end? Try it on a different charger... If it fails on multiple chargers/cables, then you device is likely defective and you will need to get it repaired/replaced.
Sorry, no quick fix here...
