Nexus 7 sometimes won't turn on

I bought a Nexus 7 a couple of weeks ago and decided to root it a week later. I used the Nexus Root Kit to unlock and root. The rom is stock though. Now I notice that sometimes if I turn it off, it won't turn back on with just pressing the power button and it won't charge either. I manage to get it on again by pressing the power button along with the up/down volume buttons. Has my rooting screwed it up?

I have the same problem, but never know what is exactly happening to my nexus 7.

U need to wipe it and flash cm or something ...it needs a nice wiping in any case

Hi, i dont think that the root is something to do with the turn on issue because i have mine rooted and i dont have Any problem.

Mine is not rooted and it just did this today, shut all the way down and was it would not even show the charge symbol, I plugged it into the wall charger and it had a "fuzzy TV" look to it, which worried me, so I unplugged it and plugged it back in a few times until that 'fuzzy TV' look went away and it was all dark. Then I held the power button along with pushing the up and down arrows, and finally one of the combinations worked and it turned on to the power charge screen.
Im thinking it went so far completely dead that it just needed to be plugged in for a little while but I see that others are having the same issue. I wish we could know more as to why this has happened.

bricked? red flashing led

Just got my nexus 4, and after it was left in cwm for about 10 minutes (while I was making breakfast) it went to a black screen and now just the red led notification led is flashing whenever plugged in, and on my mac in system profiler it shows "composite device", any suggestions?
Thanks!

Don't know if you want to do this, but you can open the phone and disconnect and reconnect the battery connector...

What was your battery level, I know in other devices some times the CPU(s) run at full speed in recovery allowing for quicker flashing this could discharge the battery rapidly. Also a flashing red LED when plugged in normally means the phone is charging but doesn't have enough charge to reliably turn on, leave it plugged in for about 15 minutes and try turning it on again.

Try holding down the VOL + and - keys along with the powerbutton (after turning it off by holding down the power button for an extended time) and see if you can get into fastboot. My friend's Nexus 4 kept bootlooping after he unlocked the bootloader but booted straight to CWM after, not letting it erase userdata first.

I have no problem doing this, the phone seems easy to disassemble, looks alot like a overgrown iPhone 4, 2 screws on the bottom. I just hope its an easy slide, I don;t want to mar it in case I have to exchange it.

I thought this as well, its been plugged in for at least an hour now.
Oh and now I don't even get the red led!
good times..

I've got the exact same issue. Plugged it in last night to charge and this morning it wouldn't turn on. Plugged and unplugged it and the red LED starts flashing. After a minute or so I'm getting the battery charge animation on the screen - so the red LED is power related. Now to see if it actually charges up and boots.

Hi nycbjr. I have seen a similar issue posted here, but I can't find the thread at the moment, try searching. If I remember correctly then he got it working by holding power, volume keys and then plugging in the charger.

Here seems to be a similar thread, maybe you'll find help there.

[Q] Nexus 10 (16Gb) completely bricked

- Steps to reproduce the problem.
I have seen a couple of other freeze ups from time to time, rather randomly, in various apps, not just Chrome.
In this case, I clicked the "All Apps" button in the lower right corner, and it froze.
- What happened.
The system froze, and then the screen went black. Now I am completely unable to restart the tablet. I does not matter how long I hold down the power button, either alone or combined with the volume up/down, it remains bricked. While connected to USB, it will show the battery charging icon in the middle of screen every 10 seconds (stays on for ~3 seconds) while I'm holding down the power button.
As of now the tablet is basically dead.
The tablet was running Android 4.2.
Does anyone have any ideas?

Power with volume up and down at the same time til you hit fast boot?

I know this will sound stupid, but are you sure you have battery?

Or try to hold the power button for about 20 seconds until N10 vibrates. That's it.

Keep it plugged in to the wall for a few hours and try again

How good are you with technology?

it may be worth reading this and possibly popping out the battery just to see if that helps.

did you resolve this issue? i just started having it. i know i was running out of battery and then my n10 wouldnt boot past the x screen after a restart. i left it plugged in but i dont know if it was charging. now it won't turn on and i get the same issue you have. i have it charging over night but i dont think it is going to help =(

Thanks for replying but after me thinking it was broken for 2 months it suddenly turned on on its own last night!
Not really sure what was wrong to begin with but when it turned on I had 0% charge for a few hours, really strange.

Same issue for me on 32Gb model.
I had a flicker screen once last week and today it doesn't boot up. I connected it for an hour but all I get is the fully charged battery icon when I press the power button, sometimes with a flicker screen or red/blue/green dots all over the place. It doesn't vibrate, it's not recognized by my Windows 8 computer.
I bought it through the eBay US deals and it sucks cause I'm in Europe...:crying:

Call +18553926398 from Skype. It is a Samsung Nexus Repair Center. From Skype it's free of charge line. I had problem with battery in my nexus 10 32gb. I had to send it to US on my cost. I spend on it (from Poland to the US) about 70euro(by UPS), from the US to Poland about $50 (by DHL). But Nexus came back repaired on warranty and it took about 1 week only. It easy and It worth to try. Important: Samsung Repair Center can send your fixed Nexus only to the US (to the US it's for free), so I used MyUS.com for 'a proxy' to send it to Poland (and this part cost about $50).

So..my nexus 7 won't turn on..

Recently updated my n7 to 4.2, haven't done anything beyond rooting. I woke up this morning, watched an episode of Prison Break via Netflix and went to work. I always plug it in before I leave, and it was saying it was charging before I left.
I get home from work today, and upon trying to unlock the device, it doesn't turn on. I unplugged it, checked the plug in it was using, even tried multiple different electrical sockets. Plugging it in usually brings up the off charging animation, but nothing. Anyone know what might be going on?
My sincerest apologies if this has been asked/questioned before; I did a little searching before I posted this and couldn't find anything about it. Thanks in advance.

Try holding down the power button for 10-20 seconds.
If that doesn't work, try leaving it plugged in for a couple hours and check back on it.
Also try plugging it into the computer and seeing if your screen has gone bad, the Nexus 7 should still come up if it's on.

...I really can't believe I made a post for this..rofl. Thanks a lot, I guess I'm just a little too impatient to hold the power down longer than five seconds.
If mods wanna delete, feel free.

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.

Had the same issue today...thanks to all for the quick and easy fix...feel like such a dork!

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, wont turn on anymore either i charged it , it was very low went down to 11% battery so i turned it off and charged it, saw the battery on the screen and now.. It will not turn on, unit feels very warm when charging. It started to lag a bit , before i turned it off.. its normal software as supplied by nexus. so..> no matter how long i hold the buttons.. its off and screen stays black..
doh....asked for RMA number..only used it for a month

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.

Hold the power button for 10 seconds or more.Happened to me just yesterday.
Plugin Nexus 7 does not bring up the charging animation.But after holding the power button for about 10 seconds,the boot animation finally appeared

New Nexus 7 Died after 2 Hrs Use
Nexus 7 shut off after only 2 Hrs of use and placed on USB charge. Tried holding button down for 30 Seconds and up/down combination with Power and nothing worked. Opened back cover carefully and patiently with Plastic Opening Tool I already had. Disconnected battery for thirty seconds then replaced connector without removing battery. Snapped cover back on. Hit power and it turned on. Do not use metal on case to open. Hope this helps. I got the idea from Youtube Video. I'm a new user and Not allowed to post links yet. Nexus 7 Teardown Review.

Thanks a lot I holded power button for more than 15 sec it got powered on thanks for your information.I am Happy now.

Man, I was just freaking out. Just got the wifi 16 on Monday. Rommed it as soon as I got home. Was using it at my local watering hole, and it suddenly just would not respond. Black screen, yadda yadda.
15 seconds of holding the power button and boom. Google logo, and then SmoothROM's boot ani. *wipes forehead* Never been so happy to see Jessica Nigri's face! lol

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!

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. However, I'd like to know if anyone figures out a fix for this incase it happens in the future.
Thanks.

[help] red light, plz help <<Solved>>

hello all,
i have a nexus 4 whit 4.4.2, mahdi rom last build and the AK karnel; I run antutu and my phone went into a coma, no button combos were working and when I plugged in my phone I got the flashing red ligh ( like my video)
plz any one can help my??
i have traid this but no result :crying::crying::crying:
1. Unplug phone from charger
2. Press and hold the volume UP button plus power button for 60 seconds.
3. Release buttons.
4. Plug into charger
5. Wait about an hour for it to charge.
That's it. This is a documented and published fix from LG and Google. The pressing of the buttons does something to simulate a battery pull - probably some sort of flushing of any remaining current out of the phone or tripping some sort of e-fuse like feature.

you will need to remove the battery and charge it for at least half hour, then connect it back to the phone.

Leave the phone on the charger for an hour....your battery may be completely drained to 0%
my friend's asus memo pad turned itself off from 60% to 0% because of wakelocks and it took it 1 hour to fill up from 0% to 5%

I was afraid of this method! but I played all out
the point is that my phone is saved!
thank you very much to you too

I'm glad your Nexus is still alive. Cheers
