Story time, fellas:
There I was, using my phone. All's well. Battery about 50%.
I put it in my pocket to eat. Time passes.
I go to check it after I eat.
Nothing.
Absolutely nothing.
Volume up+down+power doesn't get so much as a flicker of the screen.
LED doesn't light up when I plug it in to the wall or PC.
I don't think it could have run the battery dry as quickly as it did, or I would have noticed when it got hot in my pocket (which it's done before), but I'm not ruling it out. The battery health is decent; it's never jumped any significant amount or powered off below 1%.
I'm going to work on making a Moto factory cable per the instructions here, and to try and flash stock firmware but I don't know what else to do. In the meanwhile, I've just got it plugged into the wall, hoping it might charge a bit.
Is there anything else I can do?
Fwiw a Samsung branded cable is about the easiest for making a factory cable most micro USB cables lack pin 4

Silly question.... Front or back pocket? I noticed you said vol up+ vol down+ power did you try just power+ vol down held for 10-15 seconds? In the event that does nothing try the power and volume down for 10-15 seconds while plugged into the wall and look for the led to flash green...

Front pocket.
I just tried what you suggested: unplug, power+vol down 10-15 seconds, plug in, power+vol down 10-15 seconds. Nothing. This is trying to get it into the bootloader, yes?
The power+vol down for 10 seconds is the simulated battery pull... No response tho... Has it been plugged into the wall this whole time...? I was asking about which pocket to see if there was a chance at damage to the screen/ digitizer...

It's been plugged in since I made the thread. I'm gonna let it sit overnight, as if that'll make any difference. Thankfully I never trashed my old Gnex so I've at least got a phone that'll make and take calls.
Any luck?

Nope. Double checked the cable and made sure it was built right, tried that, and nothing. I bet it's that the motherboard just went bad or something.

I was using my phone like a normal person texting, using the web, watching youtube, then my battery died so when I went to recharge the phone it just stays looping at the "Stick Together" screen, so is my phone bricked? Or could it be the battery? I dont have another battery to try it out! Please Help!!!!

Odds are that one of your battery connection pins are bent. Check them closely, there should be 5 of them, like this, all straight and even:
ll l ll
if its not a bent pin, it could simply be that it isn't able to start because the battery is so flat, but every time you plug in the cable it turns itself on, thus preventing it from starting to charge.
Take teh battery out, plug in the USB, and then put teh battery back in. It should start to charge (after a pause, sometimes) without trying to power on.

Yes, and make sure you're charging on a wall outlet rather than on a PC USB port, you'll get a much higher current that way.
If your phone still won't boot, with all the other suggestions, you will have to hard reset it. (I have had to do so twice already, after just having had the phone a couple days!)
Make suire it is completely off. Press and hold in both the Volume Up and Volune Down buttons. While holding them, press and release the red End button. (But keep holding down the two power buttons.)
Until--you get a message about the hard reset. Then you can release those two buttons, and follow directions on what to do next.
Any data, settings, etc. on the phone (not the storage card) is lost in a hard reset. Fortunately, both times I had recent backups to restore from, after the hard reset. (Moral--back up often with this phone.)
Thanks for your help guys!!! It was the battery connectors that were bent, everything is all good now!

No problem, it's one of the most common causes of that problem, but not the only one.
I think samsamuel and I are going to start a pool every time that question gets asked
hah, if only we'd started 6 mths ago
I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:
you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.
I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.
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.
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.
I'm running Omni rom with eas kernel and just yesterday my phone ran out of battery, and now I can't turn it on at all. At first when I held the power button, the phone would vibrate after about 15 seconds but it wouldn't do anything. Now it doesn't vibrate or show any signs of life at all; no charging led no nothing. If anyone knows a way to get into recovery or fastboot that would be enough for me to flash a new rom but I can't even get it to fastboot or recovery. Any help would be greatly appreciated.
Thanks.
What happens when you have the charger plugged in? Is it stock charging cable and brick? Have you tried checking what happens when you plug into a computer? If it is the stock cable check the end of the cable (phone side plug) to make sure there are no burns.
You can try holding the volume-down + power.

It has been charging for hours on the stock cable and brick. There are no signs of burns anywhere, plugging it into the computer doesn't change anything either. The computer doesn't detect that it is even plugged in.
Ran out of battery? Like 1% was left? That's no good. You're never supposed to let a lithium-ion battery get that low. You might have to replace the battery. Just keep attempting to charge it and boot it up again, use different outlets, different cables and adapters, etc. This is a common issue--people are stupid and just let their phones die instead of being vigilant about charging them. And there's plenty of stories about and advice for Android phones that won't turn on after being completely drained of battery life. Google is here to help you.
Did you try what slgooding suggested?
I tried holding down the power and volume down button. I usually don't let my phone die but I went camping and left my phone in my car and I forgot to power it off I guess. Still I've never heard of this happening to anyone else.

This is a real bummer. I would suggest trying another power brick and cable. That may be your best bet. See if it has any indication it is charging.
Try a different cable to charge and press and hold that power button till it boots(2,3, 5min...) it happened to me the other day... I love my LP3 keeps me entertained...lol
