Try holding down vol up & down buttons and then the power button. Then you should be in the reboot/recovery menu. It should say start. Push power button to power up. :)

[Nexus 7 Q&A, Help & Troubleshooting] mattehunt:
I'm having the same problem, last night I tried to turn on my Nexus7 and had issues.

My device is locked and upgraded to 4.2

While booting, the device would get to the lock screen then immediately power down. While it was powering down the screen would fuzz over and glitch a few times. As soon as it turned off it would repeat the process. I eventually got it into the boot loader and I noticed "based version: N/A" I'm not sure what that means but I hit start and now all it does is get stuck at the multi-colored X logo.

Getting back into boot loader I tried recovery mode, the response is "No command". Tried plugging it into my PC and I get the little (ba dum) sound but no device or folders to be scene.

I think i'm in trouble. I wanted to see if I could root it just so the device works again but I can't access it on my PC.

Can anyone think of a step or process I forgot to try?

My Nexus 7 32Gb won't turn on either. I've been having since I got it the battery has been showing 0% since I turned it on. Regardless of how much charging I did it never changed. It ran fine and was told it might be to do with calibrating the battery but it then started to have problems turning on. It's gone off and I've tried the various power on options mentioned in this thread and nothing is working.

I guess it means a return to Carphone Warehouse. I had just got it all set-up as well. :(

I had rooted it and manually upgraded it to 4.2.1. It was running fine bar the 0% battery issue. I did the same thing to my Mum's 16Gb Nexus 7 and no problems at all with that one.

Thank You

I had been turning the Nexus on and off for the last couple of days, No "problems".

I tried to turn it on a couple of minutes ago and NOTHING. I even pluged it in and the battery charging icon did not turn on.

I also tried holding the button for 5 seconds but still nothing.

Fix:

I had to held the button for over 15 seconds to get it to turn on.

Thanks!:cowboy:
[Nexus 7 Q&A, Help & Troubleshooting] colmond:
Similar problem with my nexus 7. Battery charge shows up when i plug it in. If I try to turn it on while its plugged in, i get what looks like static and lines on the screen. When I unplug it, it dies. If I hold the power button down, and plug it in, it will boot normally, and everything seems to work fine, but the battery shows as dead, and as soon as I unplug it, it dies.Just got it, it came with 4.2.1 running on it, it was an open box from Best Buy, and developer options were already enabled on it. Looks like someone tried to root it, f'd it up, and returned it. Guess I'm taking it back and returning it as well. Just a major pain as it's 1.5 hours each way from where I live to the closest best buy and back.

My problem is an easy fix, return it. :D However, I'd like to know if anyone figures out a fix for this incase it happens in the future.

Thanks.

I always have to hold my power button of my nexus 7 for about 10sec to get it turned on but I thought this was normal?
[Nexus 7 Q&A, Help & Troubleshooting] ppp38:
Well my N7 screen doesnt turn on, I have held the power button for 30+ seconds to see it would reboot in addition to trying a factory reset. I spoke with Google and they are sending me a replacement. Im not sure what happened to it.
[Nexus 7 Q&A, Help & Troubleshooting] d3hilton:
That seems a bit long. I have noticed sometimes my case keeps the power button from depressing all the way, so I end up holding it longer. Perhaps its that?
[Nexus 7 Q&A, Help & Troubleshooting] billykxda:
Thanks to the OP for this thread.

I got my N7 for Xmas. It's been absolutely perfect. I charged it up, when to have dinner, came back to check email, and...yup,.. "dead" N7. I held down the power button, but not really for 20 seconds - I was too impatient and frustrated. So it really appeared to be a lost cause. I plugged power into it and tried again. Nothing.

Then I held down the power button a little longer and BAM, a "live" N7.

I came to this forum to see if anyone else had an N7 turn off by itself and I found this thread. Happy to see that this is not indicative of any terminal issue. It's similar to the SOD us GNex'ers get on certain ROM's.

How often does this happen to you folks?
[Nexus 7 Q&A, Help & Troubleshooting] DarkredD14:
Well sadly I am having this issue as well. Mine started after I flashed ParanoidAndroid 2.99 Beta 9.5 (i believe its 9 but i know its .5). The tablet was working fine even restarted a few times to make sure it everything was fine. Later I dropped it on the floor but the drop was not very high up maybe 2 -3 feet and it landed on carpet set it down but did not check the tablet. Later I tried to start it no go did the hold power for 30 seconds (unplugged and plugged) also tried applying both the volume up and down separately and together. When I plug it in the back light appears to work and if I hold the power button after about 30 seconds I can tiny white flashes in certain areas of the screen seems like its dead :(. So is my warranty voided and am I screwed? The tablets only maybe two to three weeks old.

HeyDarkred,

I don't need it now, but did you locate good instructions on how to open the N7? If I ever have my N7 conk-out on me again, I'll want to check the battery connection.

Thanks! And great to hear that you have resolved your issue.
[Nexus 7 Q&A, Help & Troubleshooting] DarkredD14:
Yes I did.

http://www.ifixit.com/Teardown/Nexus-7-Teardown/9623/

I did not have the tools they used. Instead I just used a razor blade to open mine and did not scratch it.
[Nexus 7 Q&A, Help & Troubleshooting] billykxda:
Thanks again Darkred.

Excellent instructions.
[Nexus 7 Q&A, Help & Troubleshooting] dottat:
Make sure you use some clear scotch tape across the internal connector to keep it tight. Also a piece across the battery to the side near the connector to prevent the battery from shifting around. Make sure you street clear of the copper tape. Glad I could help :)
[Nexus 7 Q&A, Help & Troubleshooting] billykxda:
Well, just had an interesting development. Maybe it will result in having to crack open the back and re-seating the battery connector - or maybe not.

I was just using my N7 this AM, knowing that the charge was getting on the low side, like 30%. At 23% my N7 went dead and would not turn on. When I supplied power to it, the screen cycled between displaying very slight static, and then going black. Holding the button down did not matter for the first 2 tries. The 3rd try started up just fine. But I wanted to troubleshoot some more...

So I let it go up to 24% and then I disconnected it from power. Without moving it whatsoever, my N7 went dead at 23% a second time. Since my N7 was not touched/moved during this brief time, I believe this dismisses the loose battery connector idea.

I reconnected power and sure enough, it did not respond to holding down the power button for 30 seconds until the third try. Here's what I think...

- I probably don't have a loose battery connector, given the N7 turning off at a specific power level, without being touched/moved.

- The power circuit/program needs to calibrate itself. The battery appears to be running out of power while the N7 thinks there's still 23% left

- When an N7 turns itself off, it may need up to a minute or so before it wants to respond to the extended power button press - mine did not respond the first or second time - only the 3rd time.

- I'll leave it plugged in well past the 100% charge level today, and I'll run it down to zero and watch the power level that the N7 reports. This may take a few cycles to calibrate.

I welcome your ideas - so give me a shout.

I am sharing my experience here, and will post back in the event what I discover might help other N7 owners.

N7 not powering up

Hello all

after breaking the screen and enough know how i sourced a spare digitizer.

it had been sat for about 5 weeks awaiting a cheaper spare so the battery must have drained itself..

I changed out the digitizer and all looked well.

Plugged in USB charger and i get the animation for around 5 secs saying charging but it won't switch on.

I have tried all the power/hold/ volume buttons for up to a minute and still nothing?

Please help.

Apologies if it been asked a thousand times.

[Nexus 7 Q&A, Help & Troubleshooting] raijeki20:
I got my N7 48 Hours ago. Works like a charm. Then I applied 4.2.1. The battery went as low as 15%, and charged it while turned off. Turned on normally after 90+% charge. Used the tab, and it went as low as 2% (yikes). I charged it, while turned on, then went to bed. After like 2 hours, my brother used it for a moment (he's comparing my N7 to his Galaxy Note 2) while charging, then switched off the display. I woke up an hour later to check, but what I got was the recovery menu. I selected "Start" to initialize it, but it just keeps going back to the recovery menu. It went like that for like 4 times.

After that, it was just blank - no display, nothing. I performed the Volume up + Volume down + Power but no go. Also tried holding the power down for more than 30 seconds multiple times, but nothing still. I left the tab charging for an hour and repeated the steps, but no go. I removed the cover and checked the battery cable, seated well. Disconnected the battery, did a couple of long power presses, and repeated the steps above, but still no result.

I'm leaving it for a while, hopefully, it will magically turn on after some charging.

I'm at wits end. Any suggestions?
[Nexus 7 Q&A, Help & Troubleshooting] billykxda:
Sounds like you tried a handful of methods. Right now, I would make sure that it's powered off and I'd keep it that way for a few hours while it's plugged in charging. Report back with the results.
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Beat the pulp out of your brother, and then make him buy it from you.

But seriously - if you bought a toaster or a alarm clock that wouldn't turn on 48 hours after purchase, you would be taking it back to the store for a full refund or exchange.

If it's not rooted, don't mess around - go get yourself a replacement.
[Nexus 7 Q&A, Help & Troubleshooting] chismay:
yeah sounds like your brother did a little more then "compare" to another device
[Nexus 7 Q&A, Help & Troubleshooting] raijeki20:
I left it be for like 6 hours inside the box (coz it ticks me off everytime I see it) and charged it for an hour. Still the same. :(

Yep, replacing it/ASUS fixing it would be the best next thing huh? Well, worse:

1.) I got this from Office Depot in San Jose, CA, but I'm currently here in another country (Philippines to be exact). Would they still honor the warranty here? I don't like waiting :|

2.) It just struck me that by the time I was prying the back of the Tablet open, it caused me to put some small dents at the metallic side of it. Would that void my warranty?

I've been fixing PCs for decades, but never felt this powerless over a Tablet.

BTW, Thanks for the insights guys. :fingers-crossed:
[Nexus 7 Q&A, Help & Troubleshooting] chismay:
it shouldnt matter i the marks are very small , unless it was a large dent apparent of dropping the device they may get funny about it, but they should really just replaced as its a broken product u havent really used
[Nexus 7 Q&A, Help & Troubleshooting] raijeki20:
I sent the Tab to the Service Center, and THEY VOIDED my warranty mercilessly! I almost wreaked havoc back there. :mad: :mad: :mad:

Moving forward...

Some 3rd Party tech friends of mine and I are looking to fix this by all means possible. Hey, the warranty has already been voided, so no harm dismantling the whole thing, huh? Anyway, the Technician at ASUS told me that the Motherboard needs to be replaced, but in checking the motherboard, it seems that its still getting power, and a certain IC is causing the whole mess. It can also be just about the battery itself, since if the board won't let the battery charge, certainly, it will account as a no power issue. We will continue checking this further, and I'll post updates as soon as we get results.

Hey guys! I'm sorry if this has been answered already, but i have a T-mobile GS3. I got tired of waiting for the JB OTA update, so i decided to root my phone and try out CM10. I followed the instructions on how to do the one click method using MSkip's Toolkit. I made a full Nandroid backup thru ClockworkMod before and thought we'd be good. After trying CM10 I wanted to restore my backup. After doing so, I have NO DATA connectivity thru the phone. It worked fine on CM10 initially, but now, no matter what ROM I use or backup i restore to, it still wont connect. All i have is EDGE network.

All i want to do now is use TriangleAway, unroot, and OTA update to stock JB for now. Strangely enough my app's that are already on the phone WILL update using EDGE network, but wont allow me to access the PlayStore. I'm in over my head now, so I'm asking for help. It's been over a week now searching thru forums, but i cant find any solutions. Geez...I'm a NOOB...i know.

I dont have an EFS backup. :(
