EDIT: I got it working after using the phone to charge for a few minutes
not sure if this fixes or helps anyone else but i got bootloader working
Same thing is happening to me. Two days now. I have followed all the instructions i found online saying
Drain off all the juice from your Nexus 7.
Connect your dead Nexus 7 to the charger and press the Volume Down and Power Button simultaneously. By doing this, you’ll head over to the Bootloader menu of the Nexus 7.
Scroll down to the “Power Off Device” option with the help of Volume Down Button.
Select it by tapping the Power button and disconnect the device.
Quickly connect the device to the USB charger again.
You’ll now see the Battery picture on your screen making your device working again.

However when i get to the bootloader i cannot scroll through the options or select anything. It just says "Start" and none of the hardware buttons respond.
When i do let it boot as above poster said it saw connect to charger and shutting down
weirdest thing is that it says "Connect to charger" and if i jiggle the usb it changes to "Charging 0%" but shuts off
I've tried multiple cords and chargers so the issue seems to be with the nexus
i'm at a loss and i've had the device since launch so returning it isnt an option..
any suggestions or help is greatly appreciated

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.
Hi for some reason I cant get my TF to turn on! It was working fine all day. I left work and placed the TF in sleep mode (hitting the button) When I got home about 15 mins later, I hit the power button and nothing. I read about the Sleep of Death but this is the first time Ive had this. I try holding onto the power button for 10 seconds and then releasing it and then held it for another few seconds and nothing. I even try holding the power button for one mins and then releasing it and hitting it again and nothing. I had bout 35% battery life before heading home.
I plug it into my notebook and i get the prompt the auto play message on windows 7. double click on the TF TF101 icon and I cant see any folders. On the asus sync program it tells me no device is found. While its plugged into the notebook I held onto the power button and I get that sound coming from windows (usb sound) then I get a sound coming out of my TF and the auto play message pop up. I cant even get it to go into recovery mode (vol down + power) I am on 3.1 leaked and no root. Any other suggestion before I call Asus. Thanks
Try charging it for a few hours, the battery might've drained due to some apps keeping wifi on for the whole time (using WakeLock)

Thanks. Doing it right now. Its weird when I have it plug into my notebook. While holding the power button it will disconnect from my notebook (no longer visible in my computer) then pressing the power button again its pop up with the auto play message and i get a sound from the speakers of the TF...one of those default sound on the TF. (new email alert sound) but the screen is still black. I also trying hooking it up to my TV to see if I could get a picture and no...
OKAY got a picture now with the hdmi input but no picture on the TF. I have the pattern lock screen. do i disable it? I am able tole move around but trying to find out how to disable the pattern lock screen.
yea maybe you just drained it too much. i bet a long chargewill remedy this

I am at 50% and still no picture on the tf. Now when I try to enter my pattern for the lock screen its turning red not green like before....wtf reboot and still cant get in.
Just to share, a similar but less drastic thing happened when i got mine.
Tried it at the shop for about 5 minutes just to check everything worked fine. Packed it back into the box and took it home. About half a day later, at night when i officially unboxed it,it refused to turn on. no sound, no lights, nada. when i turned it off at the store, it still showed about 50+% battery remaining.
Same thing if i attached it to the dock.
So i left it stuck into the dock (just so i can confirm that it's charging) and left it to charge for about 15mins (while worrying that i might have a DOA TF).
The light was a steady amber from the get go, meaning >95% charge.
Anyway, left it to charge for about 15-20 minutes while trying every combination i could think of, short, 10 seconds, 1 min, more than 1 mins..
Long story short, after a while, it booted up with a 10second press of the power button.... left it to charge overnight (>8 hrs first charge) and it's been fine since.
Good luck with yours.
Okay reboot again. and its not take my pattern for the lock screen. touch the first circle and its red. and it tells me to try again...wtf....normally its turn green on the circle (the first one) now its red.
Looks like my screen is dead....smh.. I am able to see the lock screen via hdmi but its not taking my lock pattern. Every circle I hit turns red (error I guess) I dont know what else to do. I try doing a factory reset (volume down and power button at the same time) but I cant get a display on my tv when i am trying to access his mode. I called Asus and got a RMA... Just wondering do i need to send in the wall charger and usb cable too? Before sending it in does anyone know what else I could do??? Thanks
Today I picked up may Nexus 7 and noticed it will not turn on. I let it charge for an hour or so, but then when I tried to start it up, I saw just a black screen. The screen turns on (backlight turns on), but still just a black screen. I read something on the internet about pressing the power button for a full 30 seconds, so I tried that. This time, I got it to flash (for a fraction of a second) the word "Google", and then it was back to the black screen of nothing.
I've never rooted, never tried to do anything fancy with it. I've factory resetted it once after an update to the OS happened.
Is there anything I can do?
You sure it gets juice? Does your charger feel hot after charging some time?
I had this to once, but got it fixed by holding the power button...

Sounds like a charging /battery issue if the 30 sec power didnt work.Did you try a different charger?
Some people have reported weird issues like this that have been rectified by a prolonged charging.
Thanks
It acted strange, but it came back from the dead:
It said "google" for 10 seconds, then a few seconds of black screen, then another 10 seconds of "google", then it booted just enough to tell me that it was going to shut down because of low battery. I let it charge another hour and then it was fine!

Quirky little buggers aren't they? Mine did it once and not since.
I just goy my N7 today, plugged in the wall charger, and I'm stuck at black screen, I did the 30 secs hold power button but it's still and black screen. Also I tried this:
1. Plug-in your dead N7 to a wall charger. (Jump immediately to step 2.)
2. Immediately after plugging it in, press Volume Down and Power at the same time.
3. Once in the bootloader menu, use Volume Down until you see “Power Off Device.”
4. Choose that option with the Power button.
5. Once your device is off, unplug the charger and then plug it back into the device.
Still at black screen, any advice???
I'm sorry for posting in this old thread.

I just solved this, I opened my N7 to check the battery and it turns out it wasn't correctly connected... Just unplugged it and plug in again correctly to make it work!

Boom!
I was having the same problem. Plugged it into a power source, backlight would come on with a black screen. Got it to show the Google splash screen a few times, but it just wouldn't boot. Tried ADB, but it wouldn't even acknowledge the thing was connected to the PC. I tried a pile of stuffs. Then I read this post. I never thought to check if the thing was actually connected, it wasn't!
Fully functional device now. Thanks for the idea! :good:
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.
Hi all,
I'm struggling with getting my 2012 Nexus 7 to start and hope someone out there can help!
I think I may have let the battery become discharged, but anyway here are the symptoms:
Connected the power lead and the tablet initially showed the empty battery icon but then started to flash up the word Google but does not boot up. Left it connected for a couple of hours. Still no joy.
Did a bit of internet research in an attempt to reset the tablet via the button combinations.
With the power lead disconnected, holding on/off plus volume+ together eventually gives a blank screen and from there holding on/off plus vol- gives the Android figure with its belly open. Hitting vol+ scrolls thru the four options of start / power off / recovery mode / restart bootloader, however when I select 'recovery mode' and press the on/off button instead of showing the Android with a red triangle it simply goes back to flashing 'Google'.
From there, if I press and hold on/off and vol- for several seconds the screen gives a momentary blue flash and then the fours 'dancing blobs' appear, eventually to be replaced with the flashing 'Google' but still no boot up.
If I connect the power lead although I can get the initial Android figure, I cannot scoll for any of the options.
All of this sounds like a major fault, but funnily enough yesterday evening I left the tablet with a blank screen and disconnected only to find this morning that it had booted and had all my apps showing, all of which appeared to be working properly. so I connected the charge lead and it said I had 17% battery remaining however the battery charge graph showed a number of major gaps and also showed the wrong date (2 days behind). So I connected the power lead and left it for 10 mins to find that the charge state hadn't moved but also that the screen brightness was reduced as if it wasn't connected. So I unplugged and then re-plugged the power lead and it said it was optimising 1 of 2 apps then the screen brightness returned to full, any appearing to function ok.
So left if for around 30 mins at which point the charge had gone up to 21% and I decided to try switching it off. Bad move!! Instead of booting up it simply returned to the flashing 'Google'. Which is about where the story started.
I've had the back off and the battery connector hasn't shifted, but one thing I did notice is that there is a fourth key switch below the vol- switch but without a hole in the cover to actuate it when assembled. Is this part of the button-press combination to restore factory seetings with the back off ??
If anyone out there can make sense of what the tablet is doing, I'd love to hear from you!!
Mike
