[Q] Backlight on when charging - Kindle Fire Q&A, Help & Troubleshooting

When i charge my kindle fire the fff bootmode charging for low battery screen comes up. then it turns off and continues charging, and then goes back to the low battery screen. i found out it was because the backlight was still on. Anyway to fix this? I cant charge my battery without it dying because of the backlight. Ive tried usb from multiple devices(my wallcharger wont work...)Please Help! I have nothing without my kindle fire!!!
EDIT: Thepooch - what do you mean. hook it up and then press the power. it doesnt work. neither does the hard reset. please help if you see a solution. thanks
Edit: Thanks! @Thepooch I connceted it via USB and when the backlight srltayed on, I did a 20 sec hard reset. In the morning it was fully charged even though it didn't indicate it was being charged.

When its hooked up to usb power it off

hope kinfauns wont dislike my quoting him. You actually need to leave the device connected to a low amp power source like a computer's USB port for FFF to enter this charging state. It will bypass the low battery charge if you connect it to a wall charger.Turn off the KF, connect it to your computer. It will try to turn on and go into charging mode. It won't turn on the backlight, but you will see that the power button has a dim amber light. Just leave it alone for a while (half an hour to an hour) and when it has enough power, it will get out of charging mode and continue booting. When it's able to boot and stay booted into the system, you can connect your wall charger and continue charging the battery. What bootloader are you running?

[Answer] How to Charge your phone when you think you have bricked it

ok there are far too many topics about people who think they have bricked their HOX.
not to say i told you so but its a bit of a stupid idea to be flashing things with a low battery anyway
well here is what to do to get it charging
1. hold power button for 10 seconds to power the phone off
2. power on with volume down held to enter Hboot
3. press power button to enter Fastboot
4. scroll down with volume down and select Power Off
5. Plug you phone into the wall and you will see the red charging light come on
6. wait a few hours or until you get green light
now you can do whatever it was you was trying to do before
flash rom / fastboot flash recovery / flash ruu (whatever)
that technique does nothing, now my battery is too low to do anything, wtf

Plug it in and leave it like that. When my phone was discharged fully, red light didn't light up for first 15 mins (or more) of charging.
i left this thing on the charger all night, it will first open the fastboot screen about 5 secs after i plug into the wall, then the red light will blink but nothing charges. On what screen do i hold down the power button for 10 sec? i can only do anything on the fastboot screen. and from there as i said, I get NOTHING.
And even with the phone off, it turns on the bootloader as soon as i plug it into a charger
Yep. In my case, when it was fully discharged, I plug cable in, there is no red light. Then, after some time, red starts blibking. After some more time, it stops blinking and continues to charge.
ok i will give it another go. was the wall charger making your bootloader start each time? Even when i power it down, if i plug in wall charger it goes to bootloader

No, I discharged completely to 0%, then phone shut off by itself.
Then I plugged in, nothing happened. No bootloader, no red light. But it was charging. After some time, red light started blinking. After some more time, red stayed lit. Thats when I turned it on manually. And it continued to charge to 100%.
So if your phone turns on, do not unplug. Try to shut off somehow, by some menu option to shut off or by press-holding power for 10 secs.
So i left the phone for a couple of hours, i come back and still nothing, no red or green light. only thing that happens is the bootloader will load and the red light will flicker on and off. it does not stay turned off no matter what i do if i plug in my wall charger

And no way to shut down the phone from boot loader?
If not, someone said that if you unplug and re-plug charger, red light will blink again and it will charge some more. and you keep doing it until there is enough charge to flash. That's what I read on one of the posts.
Get into recovery and plug up to ac power. The light comes on for a min. Or so then goes off. When it goes off unplugg it then plug it back in. Keep this up till you have some juice. Then fastboot flash the stock recovery relock bootloader, then get ruu 1.26.707. Run that ruu and it should boot. After that you can flash all the roms you want.

well it does say Power Down. but that doesnt do anything as soon as its plugged in bootloader will start back up

even if you power down while still plugged in?
If i power down while still plugged in nothing happens, it just sits there. i waited about half an hour and still didnt see any lights come on.
Well if i power down it actually will boot all the way to the screen unlock but will read 0% battery and shut off
Solution:
If you have a working ROM and your battery is at 0, just wait a bit until the LED flashes red. After a few minutes it will go solid. Then turn on the phone and boot into the ROM so your phone can charge. Do not turn device off while charging.
If you do not have working ROM, boot into fastboot, flash stock recovery (this will allow charging while phone off). Turn phone off from fastboot menu, and let charge. Then when LED goes green, flash clockwork and then flash ROM.
I have been in both scenarios so if you need help let me know.

Just because the charger light comes on doesn't mean its charging. I thought it was charging while off but then my phone drained to 0
Iii goooootttt the reeeeddd liiiiggghhhhtttttttttttttttttt !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thaaaankkksss!!!!
...it's really NOT possible to charge the phone atm when you flashed a custom recovery. Doesnt matter, if you are in hboot/fastboot/recovery or shut down your phone.
And yeah, also when the LED is red means NOT that its charging.

you can still boot up your phone, right? but its constantly rebooting because teh battery is too low when its booted up!?
...I heared reports that its possible to boot into recovery, and put the charger in.
Led shall light up but goes off immediatly then, put it out and tehn in again...repeat that several times...seems that it charges the phone for a bit while you pluggin it in.

Thanks!!

Battery Won't Charge!

I know there are other posts about this but my battery won't charge. I rooted it and it completely died. Now when i plug in the stock charger, it turns on, boots up, then dies, and repeats. I plugged it into my computer, and the orange light is dim. After about 20min, I got a message from fff saying: "Battery is too low to power on, wait a few minutes and try again." or something like that. After that it just stays dim and when i press the power button nothing happens. This has happened to me before, but i rebooted the system(with TWRP) and then i got the same message, but it charged fine. Please help.(BTW i am using it USB right now, because Stock charger still wont charge it.) Please help!!!
EDIT: Right now it goes to the Screen indicating that it needs to be charged and then it continues charging. After awhile, it will turn on to that same screen(charging screen) and i realized the backlight was lit after the indicator turned off and i cannot turn it off!!! Ive done the 20sec. hard reset but still it stays on. Help needed!!!(BTW it is the FFF bootloader i think)
http://forum.xda-developers.com/showthread.php?t=1694798
Maybe try booting into twrp and then when its fully charged boot it again to system. Can you boot into twrp or does it instantly just go to that screen again? I dont want to start speculating about the condition of your bootloader or anything else based on the info you have given. All I know for sure is theres an indication that it needs to charge. I would try quicky plugging it into the wall charger from a powered off state. I would hold the power button for 20 seconds to verify that it is indeed powered off. Most of these are likely gestures of futility. I can only say what I would do myself. Lastly I would remove the back and unplug the battery then after 5 mins or so plug it back in or plug it in via usb without the battery in and if it booted correct carefully reconnect the battery but Im not recommending you take this approach. Give it time charging via usb hopefully it will somehow break from this cycle that what the bootloader is supposed to do in the event the battery has been drained to below 4%.
Whether it is stuck like that I cannot tell you.

[Q] Kindle Fire powers off after displaying blue/white FFF logo for two seconds

I've been scouring threads and trying to solutions for this problem for the last 3 days.
After wiping the ROM and restoring the stock OS, I was about to run the Amazon update to restore the stock bootloader but as I was charging it past the 40% point, it turned off without warning. It was at 37% charge at that point. Now when I turn it on, the blue/white logo shows up and then the device shuts off almost instantly after that.
The only thing I think might've caused it is that in order to charge the device recently, I've had to wiggle around the power cord a LOT to get it to the charge, and the device turned off while I was doing do.
What happens if you go to recovery? Does it remain booted? If so do a wipe factory reset, wipe cache and wipe dalvik then select reboot. See if it will boot to the system from there.

I can't get to ANYTHING, it turns off literally 2 seconds after powering on.
Are you positive it shuts off and doesn't just boot to a black screen? Some of this sounds like a 5 second bootloop but not entirely http://forum.xda-developers.com/showthread.php?t=1623244 from what your describing it should have more charge. Turn it off plug it in via USB describe what happens.

Yeah, I've read that. I hit the power button, the blue/white Kindle Fire logo shows up (at the bottom it says press the power button for the menu) but then it shuts off right after that.
You say you restored stock by what you're saying this was a backup correct?
Yeah...what's getting me is that it was all working fine until I tried to charge it by the aforementioned wiggling the power cord in the charge port. Unless that was just a coincidence and is irrelevant.

My thoughts..
1) Its just a coincidence
2) Did you try charging the kindle overnight and then try running the KFU and change the bootmode to normal
I think Kinfuans is trying to tell you that your battery is flat. Power it off by holding down the power button for twenty or so seconds, plug it into your computer, set your computer to avoid sleeping then let it sit a few hours or overnight. It should eventually boot.
As soon as I plug it into the USB, it goes into an endless cycle of powering on and off. Even if it's off already, plugging it in makes it attempt to turn on.

With the device turned off completely, plug it in and let it power on. Immediately hold the power until it shuts off. If you're lucky, it will power off completely, then you can leave it alone to charge.

Not so lucky as it just immediately tries to turn back on. I think the thing is just toast.

You're plugging into USB correct?
Correct.
Well, getting it to shut down while plugged in, might be your only option toward getting it to charge. I've had that same problem and that's how it got fixed. You might want to leave it alone for a while and try it again. Just remember to hold the power button as soon as you plug it in, and hold it for at least 30 seconds.
No joy, whatever I do to make it power off so I can charge it is useless; it just automatically tries to power up as long as it's plugged in. I think the charge is too damaged or something.
Hey keep it on charge..sometimes it happens cos of low battery..
If u charge it enough it will work

i am having almost the exact issue. except i didn't do anything rootwise or anything really. i used it as i normally would (facebook, web browsing etc.) battery got to like half so i plugged it into a wall charger and left if for a few hours. came back and it had turned off. now it will only turn on if it is unplugged with the same results as op. 1.4a blue and white logo screen for like 2 seconds then it turns right back off. i can't get to recovery i can't do anything.
edit: when it is plugged in i can't turn it on at all.
edit2: i let it charge overnight on my computer, still the same thing. this is very disheartening.

Phone doesn't boot

Hi.
I left my Arc S went out of battery and now it doesn't boot.
I put it charging on my pc by usb and it turn the green led on. Pressing the power button, it does nothing at all. If I take the cable it when I press the power button it just blink the red led and doesn't boot.
I'm on trip and need my phone urgently. How can I fix this? Could the battery be dead? It shouldn't turn on just even without battery?
Thank you!!

Does it show the battery charging on the screen?
My arc shows the charging battery icon on screen when charging it while being off.
I think you might need to leave it charging for a while before powering it on. Another thing, try a charger instead of the pc.

Don't panic. Just connect it to the charger and wait for few minutes and see after a while it starts up or not. If it doesn't, if you can, try to turn it on with another battery.
Thanks a lot. It doesn't show the charger screen.
I don't have the charger with me, just the usb cable... :/
I'm on other island, where I'll stay until the end of the week...
So do you think that charging by USB it doesn't deliver the necessary power to boot the phone?
Thanks a lot!!
BTW, is the led turning green as soon as you connect it to the cable?

Yes!! On the begin it just blinks the red led, but in a few seconds it stabilize on the green one. Do you know what that means?
Take out battery
Hold powerbutton 30 sec
Insert battery
Connect it to the usb
Dont touch it at all and wait minimum 30 minutes
After 30 min, tap the homebutton.
Did it show the charging icon on display?

New pixel C not charging - can it be charged in recovery mode?

This is the third new pixel C I've tried this week(!) and they've all had the identical problem.. It would be incredibly bad luck to have 3 defective devices so I'm wondering if this is a known problem and there's something I can do to fix it.
The device will never go further than flashing the google logo very briefly. The light bar shows all red for a fraction of a second, then nothing. After this point the display is blank and the light bar is dead and does not respond to tapping.
If I go into recovery and select 'turn off device', the light bar is responsive but just shows a single red segment.
I've also tried the usual 10-20 seconds power off and the volume up/down/power switch combinations.
Is there any way of getting the device to charge from recovery mode?
Wonder if it's reasonable to assume that recovery mode consumes less power so the problem is a deeply discharged battery and I think that is a significant issue with Lipo cells. I assume your " 10-20 seconds power off and the volume up/down/power switch combinations" are those recommended at https://support.google.com/nexus/troubleshooter/3337561?hl=en-GB&ref_topic=6023299
Is the Pixel C charger "intelligent" ? - try a basic charger or a PC if you have a usb A/C cable?
Booted to recovery, powered it down from recovery and left it 2 hours. After a couple of attempts it booted :victory:
I left my pixel c on charge for the night (usb charge hub, 5v/2a, way I've used to charge since I got it), pixel c keyboard attached in the laptop position.
This morning I got up and press the power button to check it is charged and it was sitting on 0% saying it was charging... Power it off, leave it plugged into the wall charger that came with it and 3hrs later still nothing.
Recovery, turn off, closed it up so the keyboard is in put in the bag move, now checked it is charging, 1 red segment flashes. See what happens next. Never had an issue in the previous 7 months of using this device. Very odd, hope it is ok soon... Best Android Tablet I've had, don't really want to buy a new one...
Edit: looks like it is all good. Phew!! Bit strange.
Just Recieved and the same
Another one here with the same "issue" or strange thing that it does before start charging
I have the same issue. I can't get the thing to turn on at all. How do I even get it into recovery?? All I get is the google logo for 1 second, then the bars turn red and everything turns off.
Power button does nothing. Power+Vol Down does nothing.
I have a similar issue! Welcome to 2021. I plug in to charge, lightbar goes to Google colors and then red. It'll do that back and forth without turning on. Any ideas?
Had same Problem. Press vol up and down and then Connect the charger. Then I coud boot in recovery mode. From there rebooted in Android and charge up
