Major issue with my N7

Ok everyone I am having a major problem with my N7. This morning I noticed it was out of power so plugged i tin like normal, then I went to turn it on got the Google logo then it went to the Nexus logo. And it kept cycling through the nexus logo for hours and will not turn off. Whenever I try to turn it off it just restarts from the beginning. Now I didn't buy my tablet from the play store so I would have to go through Asus for a warranty replacement. Has this happened to anyone else in the past?
Some info. Stock, unrooted, locked bootloader, stock 4.2

Well this never happened to me before. Did you try removing the battery?

Well, to start, unplug your N7 from the power source and hold the power button down for about 15 seconds, this should force it off. From there, turn it back on and let us know what happens.

I don't see that you have tried holding down the power and the volume down. This should get you a hard reset.
Here is a short topic where a power and vol down worked for someone where a straight power down did not:
http://rootzwiki.com/topic/30101-reboot-tip/
it's the last post (#6)
Rather than trying to run the battery down, which is not all the way down when it shuts off and would take a long time to discharge just sitting there, you could pull the battery if you feel comfortable opening the case. It's not glued or anything and the battery has a ribbon connector.

So its in a boot loop? Reflash the image with Mskips toolkit option 9 after booting into fast boot mode. If that isn't the problem then do a warranty return. Not sure why you're stuck in a loop.

Nexus 7 Black Screen

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:

Stupid stupid mistake!

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.

Help Pls. My Nexus 7 2013 wont turn on.

It won't turn on even the battery icon is absent when I try to charge it. Also when I hold the power button for 15 seconds it only blinks/pulse 3 times(notification light). I bought this tablet at Best buy...and it's over 15 days now.
Can I still return. This one or get a replacement from Bestbuy/Google? My tablet isn't rooted yet with locked boot loader too.
Thanks.

Hold the power button for longer, like 30-60 seconds.
If that doesn't work, connect to charger and let it sit for a while, then repeat.

Thanks...it works now...and the battery was so drained it didn't power up for a couple of minutes ... . I checked the battery section and it was mainly caused by Vonage app...I don't know why ...it should consume about 50% of the battery... I just used it once . :/

I'm having the same problem I am completely stock with a locked boot loader. I had just took my device off the charger and it powered on and I saw Google so I thought it was starting up, when I looked back the device was off I've tried holding power for 30 seconds and even tried putting it back on the charger,but its not even showing the charging indicator.
Edit:I got it to work, I left it off the charger for 5 minutes and then tried charging it again and It started charging. I turned it on and it said I had 65% battery so I find it kind of weird that it didn't start up.

My Nexus 7 2013 wont turn on :'(

Don't work.

unplug it and leave it for around 10 minutes, then plug it back in again, wait a minute and hold down power for 30s until it boots. Should be OK after that.

Don't work

Good luck. But please do not make double posts and post questions in the Q&A forum next time, ok?

Always use the stock charter, and charge it over nigth, I think this solves your Problem.

Plug it for 30 minutes. Then restart.
If not unplug/plug battery by opening back cover.
Maybe battery was disconnected.

Did you try holding volume up + power? I had this happen to me as well and I did that combination while on the charger to get my N7 to turn back on.

I actually had this problem last night. My battery was at 20% a few days ago... left it idle, went to use it last night and bam, nothing.
Plugged it in for a few minutes and tried to boot, nothing. Left it for about 5 minutes and then just held down the power button until something happened, and finally I managed to get the battery icon to appear. It would stay for a few seconds then the screen would go black. Then it would return. Rinse, repeat. I couldn't even get it to stop doing that. Eventually gave up and just let it charge for another 10 minutes.
Looked at it after that and it was booted. Battery page shows it dropped from 20% to completely dead instantly. Not sure what's up with that.
The whole time I was doing this procedure, the notification light was pulsing in sequences of 5, if that means anything to anyone.
Anyway, tablet is fine this morning.
