So, I had this problem which I posted a thread about it a few hours ago
( http://forum.xda-developers.com/showthread.php?t=1619564 )
and I tried this steps http://forum.xda-developers.com/showthread.php?t=1394238 to restore stock.
When it finished, it booted and everything was fine, I think, and now it's stuck on the mytouch animated logo. I've been like this for like 10 minutes now. I am afraid to take off the battery and brick the phone, again but in a position where I can't fix it. It's like loading and loading and loading. I can't turn it off.
Btw, it didn't give me any error and it's not giving me any kind of error.
What you should do, if its been awhile as you have said, & by my calculations its been well over an hour, then take out your battery for about 5 minutes. Then put it back in, hold volume down then press power and hold them both til your phone boots up. If everything goes well it should attempt to update again.

I attempted the update again and it gets stuck on bootloader while it says "updating".
Maybe a bad download, try to download the PDIMG15 again

Hey XDA,
I received my 16GB Nexus 7 from Google 4 days ago. I immediately updated to 4.2.1, rooted, and then flashed franco.Kernel. I was running the latest update to franco's kernel, and had left the settings untouched from the defaults with interactive governor. Yesterday I flashed the latest nightly for Cyanogenmod.
I was using the Facebook app when my tablet ran out of battery (I intentionally let it die), and after it powered itself off, I plugged it in with the charger provided to me by Asus/Google. Because I am new to this tablet, I wasn't aware that plugging the charger in meant that the device would power on. Anyways, it did power on, and I had no plans to turn it off now that it had turned itself off. I went to turn the wi-fi off so that it would charge with less power drain, but just before I turned the wi-fi off, the device began to power down again (The charger is still plugged in, and it didn't become unhooked at any time). I begin to walk away to do other things while it turns off again, but I stop when I hear a weird grinding noise. It's hard to explain, other than it sounded like a kettle getting progressively louder and then shutting itself off when it reaches its desired temperature, only it sounded like gears and not a kettle.
A little worried, I wait a bit and then I turn it on. I'm relieved when I see the Google logo appear, and then the Cyanogenmod logo appear. After a long boot, I'm greeted by a black screen with what tiny white flashing dots randomly appearing. I turn the device off, and restart it. Same thing, only now it seems like there may be more flashing white dots than the last boot. I unplugged the device from the wall, and force shut it off (power + volume keys).
I've never heard of this happening before, which is why I'm hoping someone can give me some advice. Obvious things for me to do would be to flash stock 4.2.1 onto my Nexus 7. The reason I haven't done this is that I'm worried that my device may now be dangerous (battery melt, processor malfunction). Does XDA have any recommendations before I phone Google? I'd like to avoid Google because I've voided my warranty with them by rooting and flashing a custom kernel, so any other help is MUCH appreciated.
Thank you so much for reading my essay, and for taking the time to help,
Robert
Do your very best to revert it back to stock os and kernel and re lock the bootloader. Yes it is possible. Look for the nexus 7 toolkit. Then send it to google/asus. Best I can think of dude.

I have heard people with similar issues start device in bootloader and leave it there to charge to prevent the on/off loop and after a few hours when charged boot normally.
Hope this helps

The screen with white dots has turned into what appears to be a screen with no signal like you see on tv's.
This is even happening while I'm in recovery mode, it'll just randomly happen.
What's going on?
Can you get it into fastboot? Does it still respond to adb?

Thanks, that's actually what I'm using =) The issue I'm having is getting it into recovery mode. I am always able to do it prior to this incident, at least after two tries anyways. Now every time the Google logo displays and I hit the down volume, it just begins to boot into Android ignoring the fact I hit the volume down.

Make sure the device is off. Hold the volume up, down, and power for 2 or 3 seconds. Then let go of the power button while holding the volumes. That'll bring you to the bootloader. From there you can also get into recovery mode. By selecting with the power and volume keys.

I'm going to leave it charging for a while and see if that will give me enough time to do what I need. I'll report back here either within an hour, or sometime tomorrow around this time.
Thanks for the help so far!

Anytime man! PM me if you have anything else man.
It's 4 days old. Send it back as defective.
turn it off, let it charge for long time, after tha download toolkit and revert it back to stock.
You should be good to go.
I'd bring it back, as it is possible to cause an injury to you. Better to be safe than sorry.
Its new so just bring it back (or send) and get a new one.

Try to relock it and flash the stock rom.
After that, phone up Google and explain what happened AND ask for a compensation. This could have harmed you, and Google/ASUS IS responsible for it. Unless, of course you have messed something up while rooting or flashing the custom rom.
Anyway, you should be able to get a compensation, maybe a 32GB version.
This is not something that should happen to a 4 days old device.
did you void the warranty by flashing? i don't actually know.
granted, this sounds like a hardware malfunction (again, i don't know, could be a kernel), but, modder beware. this is a risk we take.
I'd put it back in the box and return it if possible. Save some time. If they are jerks about it then proceed:
If you can flash anything to it through recovery, download the updated Galaxy Nexus (Samsung) JB Bootloader and flash it.
I have a Galaxy Nexus and a Nexus 7. I killed my first N7 by getting confused and flashing it to my N7. It won't even power on afterwards. That should screw up your partitions enough where it won't be recoverable without a full format/reflash.
I had this issue when my battery died. I took off the back cover and unplugged the battery and plugged it back in. Put it back together and charged it up for a few hours. All has been well since, I'm pretty sure its a common issue with N7's when the battery gets low.
Had a similar issue once after letting it discharge to 0 and plugging it in and trying to boot right away. Mind you I didn't have the noise, just the snow effect. My solution was to turn it off and let it charge for a few minutes while off. After that it worked fine.

Do your best to revert it back to factory and call them up about that possible firecracker before something else can happen
keep us informed about what happens too if thats ok
Stock - and the same problem...
Hi, my N7 is two months old and worked perfectly. It's clear stock - never rooted, modded etc. Today I suddenly can't run it - it boots, battery level is 24% (on bootscreen), and after few seconds shows 1% and starts to snow - sometimes with sound. I haven't installed anything new for few weeks, so I'm sure it's not a virus, trojan etc. WTF?
PS. Sorry for my English...

I confirm that. I had this issue already a lot of times. When the battery is completley discharged it seems that the display or the graphics hardware is not able to start as expected. I just left it powered of (or in that charging screen) for some time (>1h) without using it. Then it started normal.
But also for me, no noise, just the screen like on an old TV without signal.
I have had a nexus 4 for a while, and I rooted it about 2-3 months ago, but today for absolutely no reason, it won't turn on (please note it was fully charged when I left it). I have tried to leave it plugged in for a while, and after I tried turning it on nothing happened. When I connected it to my computer it showed up as QHSUB_DLOAD. I don't have any custom rom or kernel, all I have is an unlocked bootloade on my rooted nexus 4. I tried holding the power button for over 30 seconds (it was suggested on another post here at XDA) and it still wouldn't do anything. Please help me, I have no idea what happened or how to fix this.
PROBLEM FIXED!
jonapunk sent me a message with a simple procedure to solve this:
"Try volume up and power for 20 sec. Then press power button one more time"
I have put his message up for everyone to see in case they encounter the same issue.

There are several threads already dealing with this.
Got a new replacement Nexus 4 from google today and turned on phone and the colours were all fuzzy. After turning screen off, it doesnt turn on. Doesnt go into bootloader mode. Tried all the button combinations also.
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.
