I've got a significant problem - my nexus 7 won't charge. I have tried charging the thing overnight connected to its original charger (though not with the original cord, which I can't seem to find).
Basically, when I turn it on, it will immediately Shut Down at 0% battery.
I have tried the first option listed here: https://support.google.com/googleplay/answer/2668668?hl=en but - I am able to boot into the bootloader by holding power and volume down, but when I do so, the bootloader appears to be frozen, and will not respond to presses of the volume up / down or power key. Once I get in, the only thing I can do is hold the power button for about 15 seconds, which forces it out of the bootloader.
Heeeelpppp!

Anyone having boot problems?
Waiting the case, i have put my tab in his box moving from a place to another, when i took it i saw a green andoid image with the message "POWER RESET or UNKNOWN UPLOAD MODE".
Now it is blocked in this message state. Can't turn off, reboot ...use it...
Anyone know the way to reboot (key combination)? if galaxy tab has a recovery system? or something in order to resolve this problem?
Just to know, no root attempts, only some application normal installed from the market...
hi, i think if you press the power button and leave it pressed, it will reboot.
after the battery charge finished and the recharged all work fine...
i think the "block state" has been caused from the home+volume keys that probably were were pressed in the box..
it would be usefull to know these key-press effects
They are standard android combos. Google is your friend.
I stumbled across this screen while my Samsung SGH-I897 (Captivate) was powered down, hooked up to my PC using the USB cable and the battery was half way charged. I held down both the power and volume up buttons for a few seconds and got to this screen before the unit attempted to boot. It remained there until I held down the same key sequence for about 5-7 seconds. It's now back to a powered off state, still hooked up to my PC via the USB cable, and the display has the standard large battery icon showing it at about 50% charged. Leaving the Captivate idle will continue to charge my phone via USB (abeit slower than having it attached to the power adapter) and the screen shuts itself off. It practically looks like it's fully off or fully dead like this, but it's not.
It seems my Nexus 7 seems to be hosed.
It was running the latest android os as pushed out by google (maybe 4.2.1?) Not sure what I did, but I am in the APX mode and I cannot exit it. The screen is completely dark, and I am not sure it is working when I press the buttons.
I have held:
Power button for 60+ seconds
Power + volume up
Power + volume down
Power + volume up + volume down
If the device is plugged into my laptop, I get a beep after holding any aforementioned combination indicating that the system detects the device but it shows up in the device manager as APX with a question mark.
I have opened the back, and disconnected and reconnected the battery.
Prior to noticing it was not working, I set a torrent download using µtorrent. My initial guess was that the battery discharged, but I have been charging it now for a few hours without any resolution.
Please help! I am past the returns for Walmart, and I do not want to ship it to ASUS to have it repaired.
Bump.
This is frustrating. I have never owned an android tablet before, and I had no intentions of rooting it. Now I have no idea if I can even recover it. Other threads are saying I am hosed because nvflash does not work on the nexus 7.
Any ideas besides throwing it in the garbage?
Try letting the battery die.

Hi guys,
My battery went completely dead, left it to charge over night, now wont boot at all. If its plugged into the charger and I hold the power button the full battery symbol (black and white) shows for about 2 seconds and then goes off for about the same time then reapers. Any ideas?
Device status:
- Stock rom
- boot loader unlocked
- non-rooted
I've tried :
- Hold power for 30 seconds to a minute
- Hold power + volume buttons for 30 seconds to a minute
- no response form my computer when its plugged in
- no response when trying to boot into fast boot
I am aware this has already been asked. I've tried the other threads but no luck
EDIT
I got mine to boot. I have literally no idea how, I just tried the power button again and it burst into life, although the battery was empty.
I think this could be due to not letting the battery die enough. I normally let my phone (HTC One) so completely flat every month or so but i've never done it for the Nexus 10.
The same problem please help
Serious bump. Ive tried all of these methods, but it just shows the charge icon when plugged in. This is the first time for me that it wouldnt just turn on after going into that sleep state. Charged over night.

I think this is the same issue that many (or a few) people are having. Mine, for example, will be at 100% charge. Then, sometime in the day (without using it) it will die. It will not power on. When I plug it into a charger, it will show the charge indicator on the screen, and I can get it to power on 50% of the time right away by holding down the power button for about 5-10 seconds.
When it boots up, the android tells me it is at 0% battery. If I leave it plugged in it will usually show 100% again after a short period of time, but until then, if i unplug it, the tablet powers right off.

Here is a pretty good thread to see the issue.

Here's a question for you:
Watch your battery life. At any point, does it begin NOT draining? Such as remaining at 60% for 2-3 hours during usage? If so, you may have a defective motherboard and require warranty replacement, as that was one of my symptoms.
After my NX4 was upgraded to 4.4.2, I have some problems.
I was getting the "X" loop, so I reset the phone with the root toolkit and reloaded kitkat 4.4.2 KOT49H.
Now I have the following issues:
1. The power button won't switch the device on.
The only way to power on is to go to the boot loader and press START.
2. When I power off, the phone won't charge (no charging indicator).
When I power on, battery status shown 41% - Not charging, even though the battery symbol shows that the power is connected. (the battery is only a few months old).
By the way, usually when the phone in powered down, you get a vibration when it finishes shutdown. This no longer happens.
Can someone please help?
This is my first post.
I'm quite technically minded when it comes to PC's, but noob when it comes to phones.
I own a Nexus 7 2012. It got full discharged over the weekend. So i put it for charging and wait for several hours. The tablet won't boot and neither any big battery symbol would come on the screen. I kept it for charging for more than a day and still it doesn't power on.
Tried power + volume down combination and nothing.
I am using original charger and cable and they work with other android phone so they are not defective.
How do I revive my nexus 7 ? Any suggestions ?
The tablet is not rooted, if it helps in any way.

Hello,
Below is listed a few troubleshooting steps that can power on a Nexus 7 when the battery has been completely discharged:
1. Charge the tablet from a wall outlet for one hour > Unplug your Nexus 7 > plug your Nexus 7 back in within 10 seconds > Hold the power button for 15 seconds.
2. Connect your Nexus device to a computer’s USB port while the computer is on. > After 10-15 minutes, disconnect the USB cable from your Nexus device and reconnect it within 10 seconds. > After 1 minute, check to see if a battery icon appears on the screen. > Press & hold the Power button for at least 15 seconds to see if your device turns on.
3. Press & hold the Volume down button. At the same time, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen. > Press the Volume down button until the screen shows the option to Power off. Press the Power button to select that option. > Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen. > Once the battery icon appears on the screen, allow your device to charge for at least 1 hour before turning it back on.
I hope one of the steps listed above helps you power on your Nexus 7. If you need any further assistance please email me and place case number N140904697 in the subject line for reference.
