Used my device last night to do some reading and the battery was about half full.
Went to use it tonight, won't turn on. Thought something killed the battery, so charged it for an hour.
Held power button, nothing. Tried volume up then power, nothing. Finally got it to do something by pressing volume down and power. It comes up to the Odin screen.
I've never rooted/loaded any roms or anything, so anybody have any idea what the heck happened or how to get my device back to normal?
Thanks for any help.
Have you used the stock AC wall-charger to charge it up?
Yes, it's charging now while I am reading all about using Odin and downloading a stock firmware...
Not that I know what I'm doing <grin> I'm hoping it powers up after I charge it some more before I go mucking with it...
Thanks, Samsung! I'd much rather be having this fun instead of reading a book. Where is the damn ICS update? Honeycomb sucks.
I would let the battery go flat which is the same as removing the battery on a phone and hope that allows you to re-boot normally after charging then I would try a factory reset to clear any problems before going down the re-flashing road.
Well, looks like letting the battery go flat is my only option because after charging all night it now won't even go into Odin Mode.
Do you have a general idea how long it will take for the battery to die since there are no indicators? Should I expect days/weeks?
Sure wish I could pull the battery or use the paperclip trick like on other devices. This thing is a very expensive (imported) paperweight right now.
EDIT: Any idea why I couldn't get to the boot loader (volume up + power) to reset the device but the Odin mode worked?? I don't think it's the button, this device has been coddled. Just sits on my nightstand until I read a little at night and put it back.
Uh 九千., I'd thank you twice if I could.
So I go to pull the usb cable and wall charger behind my nightstand to bring to work and it's NOT the original charger. I forgot it came with the European power adapter so I had to use a generic USB charger.
I grabbed the Samsung wall plug from my 8.9 and now it shows the battery with a yellow exclamation mark. I'll try charging it and go from there.
Very strange, considering I've been using the other usb wall charger since I bought the device maybe six months ago...
I'm hoping for the best!
EDIT: IT BOOTED and it's charging... What a relief. Thanks for the help guys.
EDIT 2: So before, it was NOT charging... It got so low that only the Samsung wall charger could get it going??? Very strange.
So I was using the new Hangout app to video chat, ignored the 4% battery warning, and eventually the phone shut off due to low battery.
After that I attempted to charge it all night, using various USB cables, wall units, the charging orb, and without, and a PC, and nothing happened after leaving it all night.
Holding the power button does nothing, trying to load the bootloader nothing, and holding both volume buttons and power does nothing. Simply unable to boot it or turn it anyway on.
Plugged into the PC also shows nothing.
I called google and requested an RMA, but I'd like to see if there was a way to backup some pictures from it.
Is there any known solution for this? I feel like the battery died beyond the point of no return or something.

It is really drained then... You can fix it by Manually applying current to it so it can charge a little. That's the only fix I can think of. And if I remember correctly there is a thread here on XDA which demonstrates the procedure.
Charge it for 5 mins, unplug it, then plug it back in.
I heard an answer to this somewhere, if you browse the N4 forums for a while you might find it, bit I think it was charge it for a few hours via normal USB, then hold power for 30 seconds to a minute? You might need to charge it for a few hours again after and hold power for 30s again. Good luck

Same thing Happened to me.. it died overnight and I plugged it in in the morning and now I checked a few hours later and it didn't charge! Wont turn on, I've tried various button combos and different chargers and cables.. Help!!!
I'm alive! Phew. So After trying all the combos with it plugged in.. I eventually waited an hour or 2 hoping it would charge.. and then tried the same thing after unplugging it ( after giving up and running out of ideas). With the phone unplugged I did power+volumne down and within a few seconds I felt a buzz and got into the bootloader.. then I rebooted. Phone booted up but battery was at 0 so it shut off instantly. But now when i connected the charger back I got the battery icon - Yay, it started charging!
This worked for me so just putting it out there in case it can help someone else

Yea, I got it working the same way also, why is it so iffy? The phone shouldn't even need a battery to boot if it's plugged in.
It should be able to bypass the battery power check to USB, and charge the battery in the meantime.
It appears dead. It's late at night so i've yet to try googling about recovery through a pc of some such, truth be told while i can flash a rom with instructions, i'm no guru or anything. It was running CM 10.2? the latest stable release for N10, think that's the one.
I was just browsing a forum, and after posting, the disply started to stutter as i scrolled up, when i stopped scrolling, the stuttering decreased, and then as i scrolled and scrolled fasster, the stuttering increased until display turned black (stoned curiosity...) and now i can't get anything out of my N10. Holding power, trying to reboot into recovery. Nothing. No lights, sounds, vibrations. None of the normal stuff.
anyone got any ideas for me to awke up to? I think that if i can't get any life out of it, then would it be a case of trying to sideload or such with ADB? as i say, i'm a complete rookie, just a couple of flashes under my belt.
Second question, i probably have the answer to, but am i right in thinking custom roms void the warranty?
edit: Plugged it into the wall a few minutes ago. It had had about 40% remaining, but when i plugged it in, i got the battery simbol on the screen (big white battery charging in center) and any time i press or hold the power button, or with volume buttons, i get nothing but the icon. I'll keep it plugged in for now and see what happens. But by the look of i assume if it can do that when plugged into the wall i sohuld hpoefully be able to connect via my computer in some manner
If by stuttering you mean blinking, this has happened to me when my N10 was on charger with a dead battery and it drew more power than what the charger could provide. When you scroll, the CPU frequency gets bumped up and the tablet consumes more power. After a while it just turned off for me (when I changed to an other app I think), when there just wasn't enough power.
So I would suggest leaving it on charge for a few hours, then try holding all buttons and see if you can get into bootloader. I've had the battery levels not display correctly on some custom ROMs, (for example I would do a reboot at 60% battery and after it reboots it only said 13%) so just charging it a bit might solve the problem.

Thanks. As of 5 minutes ago it got back to life. All battery apps showed 40 odd. Strange.
i think your battery has gone/ on its way out, exact same happened to mine, you need a pogo charger and the original wall adapter to provide enough power to switch it on. Only thing which worked for me, hope it works for you.

Might be the battery, might be glitchy software. Plugged it in via USB and it worked sometime later. Will be keeping an eye on it.
It will probably be fine. I thought I had a bricked N10 but turns out the battery was dead. It is fine now. THought I had a bricked N7 also, turned out the battery plug got loose, (screen would flash every 2 seconds with static on the screen) popped it open and oushed the plug in and that is fine now too.
If it continues to die around the 40-50% mark, you'll need to send it in for repairs. Make sure they don't just try replacing the USB port on it, the battery itself is the culprit.

Hi everyone,
yes this may seem at first similar to several other posts, but rest assured, I have googled from one end of the galaxy to the other and so far no solution has helped me.
Basically, my N7 a month ago was bootlooping loading android, this has happened before and usually i just re-load the factory image and i'm good for another few months. This time however, I was busy and said, no problem, i'll load the image in 2 days or so. By then, my N7 appears off and does not react to me pressing the power button or plugging in the charger. My assumption is it was in my bag and kept bootlooping and eventually drained the battery.
On my google searches, i've noted that there is a huge issue where when the battery drains completed, it is a pain to get it to turn on. Most people seem to be okay letting it charge for a while and holding the power button for 30 seconds or so. I've looked at google's official video about this issue and their steps to fix it, and i have not gotten any of this to work. I've held the power button for not 30 seconds, but several minutes until my finger became sore and it won't turn on. I've also done this holding down the power and the volume up button, volume down button, both etc. all combinations. I've left it on the charger for days and when i unplug and re-plug the charger, i don't get a hint of the screen powering on, let alone the battery charger icon you are supposed to see. I've tried this with my other chargers as well. The n7 charger is fine, i use it for other android devices no problem. If i plug this in the computer, i get a driver install failed error as well.
I've gone as far as taking off the back cover and double checking the battery connection which apparently gets loose quite easily and this is fine. I know my charger is fine, because i use this charger for other phones and they work fine, i've also tried using the usb cable to the computer and that does nothing either.
I would rule out an issue with the usb port on the device itself, because i have the dock which can charge the nexus 7 from the connections on it's side, i think it would be highly unlikely that both these pieces failed.
I am at my wits end, i really liked this tablet and want to salvage it as best i can. Only thing is i can't really do anything with it, all my google accounts are saved on this device and i'd rather not reset all my passwords if i attempt to sell this for parts.
I'd like to know if anyone has any other recommendations on what i could try, even if it is swapping out hardware inside the device. If i can salvage and sell this for something, i am willing to do that, i'm just not sure if it's something with the hardware at this point or if it's that dreaded battery drain issue.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
