In noticed that after the 4.2.1 update my Nexus 7 won't boot anymore.
Somtimes i had to try it over and over again for 30 Minutes ore more.
Then i figured out that after pressing the power Button my Nexus needed >20 sek. before the google Logo shows up.
That explaind my "won't boot" problems.
But after i got a friends Nexus 7 for a couple of days i recognized that his Nexus 7 just needs about 2-5 sek. between pushing the power Button and the appearing of the google Logo.
I thought there might be a problem with the Update on 4.2.1 and would like to know if there is any way to flash the factory stock ROM to my Nexus 7 without unlocking the bootloader ( maybe something like KIES from Samsung )?

My N7 was flawless until some days ago.
Usually to turn on, I had to press the power button for 4s and it would turn on, never ever failed. Also on the boot sequence (the X of nexus), it took relatively low time, even when I had all of my currents apps installed (nothing changed).
For the last days, it's happening that sometimes the device doesn't wake up after pressing the button. I've checked and I have to press it for 20-25s in order to see the "Google" logo and have it start booting.
Also, the nexus "X" boot animation also randomly takes like 4x longer, and it seems to not have any relation with the 20s pressing issue, since it happened me both with the 4s and 20s pressing power-on times.
But both of those issues came together.
Anyone else with the same issue? Would a factory reset solve the problem?
Thank you in advance.

How much memory is free on your N7? I've seen posts from people who have had similar issues when they came close to filling up the memory on their N7.

16 GB model, more than 6GB left.
It has been like that for the last 2 weeks.
My screen glitches (think of TV static, but striped and colored similar to the background image) about 5 seconds after booting into android (after the nexus logo loads.
The tablet is fully functional doing the 5 seconds. After that, the screen glitches like above, and I can hear a faint sound from the nexus 7 that grows in pitch until it bursts and the device shuts down. Then, it tried to boot again and this process is repeated.
I don't know what caused this - I haven't used my nexus 7 for few weeks or so, and the last time I used it it was working.
The bootloader is unlocked but it is running stock 4.2.
I have tried booting into recovery mode and wiping data, but that doesn't fix anything.
Anyone know how to fix the issue?
I have a Nexus 7 tablet running 4.2 official, stock, OTA 4.2. The device isn't even rooted and somehow i turn it on today and it's stuck at the Nexus splash animation and has been for hours. I JUST fully charged the battery, i've held vol up/down and power until it resets, i've done everything and i can not make it turn on. Is it still possible to use like a Toolkit or something on an unrooted device? I don't know what happened to it. Any suggestions would be appreciated.
Thanks in advance!
Well if you haven't done anything to it just call Asus and see what's up and try and get a new device

I was using my Nexus 7 (2013) this morning surfing some sites, when all of a sudden my touchscreen just up and died. No laggy response, no jittery response, just nothing. I can't even unlock it when I wake it up. I can't power it off (as far as I know), since after I hold the power button down, I can't select Power Off.
I'm rooted running a stock 4.3 as fas as I know. Any ideas of where to begin? Thanks in advance.

I had the same issue when I didnt use it for 4 days. Touch would respond and when the power off dialog came up I couldnt touch it but just hold the power button longer and it will reboot. I held it for about 15 seconds maybe 20 and it will restart
Well, if that previous posters suggestion does not work, or any software-related solution, my first suggestion would be to send it back for a replacement, barring that, it sounds like something could have come loose, if you're the type to try it, you can see how that is addressed with the 2012 version:
Google for "How to Fix Nexus 7 Touch Screen Problems", the video is by Tampatec.
Happened to me too once but i was on a custom rom and kernel. I freaked out when the touch wasn't responding!
I held down to power button to power-off/reboot. It seemed to result in a bootloop and i wasn't exactly patient because i was freaking out a bit!
So, i powered down the device again, booted into recovery (TWRP) and to my relief the touch worked!! I just rebooted back to the system and everything was fine.
This happened to me on stock android 4.3 twice. I believe it is a software issue with the last one or two factory builds of 4.3 for this device. As previously stated, my problem was fixed by holding down the power button for about twenty seconds until it rebooted.

I got it to reboot and that seemed to do the trick *crosses fingers*

Had this issue too a few days ago. I connected it to my PC and rebooted it via adb reboot command.
Occasionally I get this issue after switching the screen on running completely stock 4.3, but I can solve it by holding the power button - not to reboot, but just so the menu comes up. That alone wakes the touchscreen up for me.
I used the nexus toolkit to unlock my nexus 10. I allowed it to reboot from the software interface and it failed to boot into fastboot. Now it is stuck in boot loop. I've tried 100 times to press power and volume buttons to access stock recovery and all it does is vibrate. What am I doing wrong?

How do I get into fastboot? I've tried holding down power and both volume buttons but it doesn't seem to work.

Is your device charged enough? Or doesnt it show anything at all when plugging in?

When this first started yesterday it was fully charged. I believe it is low now but I have it plugged in. It shows the battery charging icon at the moment.

Maybe it was too discharged? Have you tried after about half an hour?

Just tried again. It's been charging for 4 hours and still does the same thing. I hold all the buttons down and it vibrates about every 5 seconds or so. It's strange, I've installed custom roms on several tablets and phones but never had this problem.

Hi,
I hope you figure out how to solve the issue with your nexus by now. If you have not then I would like to tell you that I experienced the same issue. I used nexus toolkit to get back to stock room after rooted with the toolkit and then flashed Cyanogen nightly. But when I tried to boot up, the screen stuck in a bootloop. And I tried the button combination many times, all I heard was the vibration after 5 seconds. I spent days reading on the xda and Android forum but could not found out why. But then I read about Flaws in Nexus 10. One of the user mentioned that he could not get into the fastboot mode with the button combination and he returned his device as a defective unit and Google accepted it and replaced him with a new one. His conclusion was that the device actually was in fastboot mode even the screen wasn't on.
So I thought my device was suffering the same defect, so I plugged it in my laptop after hearing the vibration, my laptop recognized it and I was able to flash the stock rom. After all this, I still not manage to get into fastboot mode on my Nexus 10. A friend of mine tried to fix my tablet, he kept it for a month and only twice he managed to get the fastboot screen shown up and that occurred after when he had been playing with buttons for more that 3 hours.
I do hope that you have fixed your tablet by now, if not I hope this info will give you some clues, and sorry if you don't understand my English. It is my fourth language and I'm really not fluent at all.
I have Nexus 5, and nexus 7 2013. The button combination to fastboot works fine no problem at all.
