When you say the screen went crazy I'm guessing you mean filled with static and wavy lines. Please correct me if I'm wrong.
If that's what you're experiencing, I had the exact same issue, but it occurred when I drained the battery to 0% while it was plugged in to my computer. Apparently, the USB ports on most computers don't provide enough juice to keep the N7 alive while using it. I just long-pressed the power button (for around 30 seconds) after it had charged for a bit and the N7 booted right up.
I solved the problem by charging the N7 from a wall socket (and not from a USB port on a computer) when I want to use it while it's charging.

Yes, that what I experience, yeah'wall socket helps but if u run something right after it just boot up, than the lines will dance again^^

If you kill the battery that far dead you need to let it charge 20 or 30 minutes if you're having issues like that.
I understand whats happening now.
OP, if you're going to use the computer and you completely drain it like that, let it charge a bit before you power it back up. Its apparently a habit, and I just don't think its a good thing to kill it dead, connect it to a power source and then immediately kill it again by drawing way more power than we have.

[Q] Nexus 7 - brick

Hi All,
I've gone over the forum and tried consulting some of the threads with no luck.
Two days ago I left me Nexus on and it run out of battery (I think, since its no longer start).
This led me to do the following:
1. I've tried connecting it to the charger - which made no difference.
- I've tried different outlets and two different cables that I had (the original and one that belongs to an HP touchpad).
2. When it didn't work I've tried connecting it to the PC - The USB wasn't recognized in any of the hubs.
- I've tried using 'Nexus 7 toolkit' and 'Nexus root toolkit' to install drivers and it didn't help, the device appears as 'Unknown Device'
with Error 43.
3. I've tried 'long press' on the start button for 30 seconds (and more) several times with no luck.
4. Then I've tried pressing on all 3 bottoms in two different scenarios:
- in my hand: nothing happened.
- connected to the PC: the computer tried to installed something called APX and failed.
then I tried to re-install it with drivers located in the 'Nexus root toolkit' and it installed it as 'Asus Transformer Prime APX Mobile'
and I don't know what to do with it.
5. I've tried recharging it for 10 hours! and the charger isn't even hot.
Since is a combinations of several threads that didn't help I've thought that I'll create a new post.
Can someone please help?
I'm stuck and run out of solutions.
Thanks

You actually are bricked.. Some how you got yourself into app mode which basically means your tablets a brick until there's a way to fix it but there currently isn't for the nexus 7, you could try sending it back to Google but Idkk if they'd replace it for you

What about OP's charged not even heating up? Even an APXed device charges, AFAIK.

why don't you think they replace it?
xfrancis14 & Awesoham Thanks for the reply.
xfrancis14, why don't you think that they'll replace it?
The device is still under warranty (bought it two months ago).
Awesoham, in both states the charger is not heating up. I don't know - maybe the charger is damaged.
I'll try connecting it to the computer, maybe it will charge it (as much as it takes).

I am having the same issue
I bought my nexus 7 back in July and I haven't had any issues with it until this morning. I was using it with about 16% battery left and all of a sudden it just shut off. So I put it on the charger for about 2 hours and tried to power it on. I have to hold the power button down for 20 seconds or so and after it gets to my home screen it will stay on for about 5 seconds before the screen goes crazy and shuts off. All of this done while plugged in to power.
Any ideas before I call Google?
This better not be a bad experience...

did you try connecting it to the PC?
maybe you'll be able to charge it from there? (that what I've seen suggested in other threads).
If you call Google, can you please update me about there solution? or if they replaced your device?
Thanks.

Well if you rooted or unlocked it, your issue is a software issue and they most likely replace a software defective nexus 7 if it's rooted or unlocked
Sent from my Nexus 7 using Tapatalk HD

Use something to pry open the back and remove the battery. Pop it out and in, let it charge and then try. good luck!

I haven't got around to root or unlock the device, so this is not going to be a problem.
The problem is that I leave in Israel and bought the device in the U.S, so it quite a problem
sending it to google.
This is why I was looking for another way to solve the problem.

Assuming you don't break anything. The cover isn't meant to be removable, but it is certainly easy to do. Just be mindful of the NFC Chip inside the plastic backing.

I've took the cover off (with the help of this guide: http://www.youtube.com/watch?v=XC2aGLseN64)
disconnected the battery plug and reconnected it.
I'm trying to charge it now (although it doesn't seem to be doing anything).
I'll update in a few hours.

Man what a bummer.
Maybe you could try to RMA it at Asus in Israel?
Have you checked their website?

I can give it a try.
I'll check the website now.
I tracked another solution: https://developers.google.com/android/nexus/images
Do you think that this might help?
I didn't change the firmware, but maybe it will be able to connect to the device in fastboot?

Another question [APX]
I mentioned that I was able to put the device in APX mode by pressing all 3 buttons while the device is connected to the computer.
I gave it drivers I've found in 'Nexus root toolkit' and it was installed in the device manager as 'Asus Transformer Prime Mobile'.
I've found this article in the site: http://forum.xda-developers.com/wiki/Nvflash
According to it, I'll be able to fix any brick situation. Any one knows how?
do you have a HowTo guide, or something more concrete?
Thanks

[Q] Nexus 7 won't Charge

After not using my Nexus 7 for about two months I plugged it in to charge it up. I came back to it in 30 minutes to check the progress and to doodle around while plugged in and it wouldn't turn on. There was no sign of life at all. I pushed the buttons on the side in multiple combinations with no results.
This thing has barely been used. A few pdf downloads; a movie; some writing's. Nothing major. It's bone stock except for the first upgrade on day one to the new Jelly bean.
Pretty frustrated.

Bump. Really? No one one this board has run into this or knows about this? I can't believe the Nexus 7 is that bad that letting it sit for two months would kill the battery. Would an Ipad do this? Just looking for a liottle help here.

I have heard of this. Seems some models don't take well to dying. Send it in for RMA. You will probably get the issue fixed permanently which I'm sure Asus is aware of.

Before you do that you might want to try a different micro USB cable if you have one and/or plug your nexus into your computer USB and see if it charges that way to check if your Asus charger is having any issues.

Tablet bricked itself?

Bought a refurbed 32GB WiFi from sears on Jan 2nd and had no issues except for a screen flicker. I was running a CM10.1 build from around Jan 26th and the latest Motley Kernel.
Yesterday I was using the tablet as usual, but I hadn't charged it in a couple of days
so the battery was getting low. After I got home from work I went to use it but the screen wouldn't come on. I figured the battery had died so I went to charge it, but I never got the powered down battery animation. I've tried holding down all 3 buttons for at least a minute and nothing is happening, and when I connect to my computer I get a USB not recognized error.
I have about one day to return the device to sears with the 30 day warranty, but I just thought I'd check to see if anyone else was able to resolve a similar issue before I do so that I don't lose all of my data, and the fact that if they do get it running again that its rooted and running CM.
Any suggestions, or should I just take it back?
Sent from my Galaxy Nexus using xda app-developers app

Sounds like the Nexus has had it, take it back is most likely the best option

AW: Tablet bricked itself?
One thing I learned from here, is that I never ever should let the nexus 7 run out of juice. Seems to be a death sign..
Jup, take it back.
Sent from my Nexus 7 using xda premium

Not a death sign.
You just need to let it sit on the charger for about 1/2hr, then it should boot right up. People panic when the device doesn't respond or screens start flashing, but it won't boot and they start mashing buttons and posting about their 'I think I bricked my device'. After a device has run down it might take a long press of the power button to get it to boot and/or sit on the charger for a bit.
Running the battery down should not be confused with the Sleep Of Death (SOD). The fix for an SOD is also a long press of the power button.

Dirty AOKP 3.5 <&> m-kernel+ a34(t8)

try connect to charger at least a half an hour, then press just power button for 1 minute. i had similiar issue, and it worked for me. if dont work, maybe you got battery connector loose problem. try search in general section about that.

[Q] Tablet bricked by USB OTG

Hey guys,
Well I screwed up and I think the only thing to ask is whether this situation is covered by warranty.
Yesterday I received my new USB OTG cable, because the other one stopped working as soon as you would turn it a little. I tested it with a mouse yesterday and it was running flawlessly. Today, I wanted to test whether it would be able to mount USB sticks, so I took the nearest one and plugged it in. The screen was locked, and after nothing happened I tried to unlock the screen, which wouldn't work. The rest is history and a lot of confusion and anger.
The problem might have been that it was a bootable USB stick containing Ubuntu 13.04, but I'm heavily doubting that this caused a brick. I mean, just plugging a USB stick in cannot brick a tablet? Wubi is an .exe-file an AFAIK Android cannot do anything with this by itself.
I was running PA 3.98/stock kernel and didn't have any program like stickmount installed. I cannot access the bootloader, charging the tablet gives no response at all and when I try to connect it to the computer, it just says that it cannot recognize the device.
Thanks in advance :crying:

Hmm, anyone? I guess I'll ask it in the Ubuntu forums tomorrow too.

Have you tried holding down the power button for 20-30 seconds to force a reboot? Is it possible it is suffering from the low battery bug? By that I mean is it possible it had a low battery or it thinks it had a low battery and freaked out?

Just wow, this really worked.
I feel so retarded now, I already tried holding down power for a while but nothing happened. Guess I was kind of freaking out and couldn't think straight anymore.
Could you tell me more about this low batt bug? Because my tablet was at 1% when it just booted and it was around 40-50 when it gave up.

Glad I could help, sometimes it's the simple stuff that gets overlooked in moments of panic. There is a sticky in this section and other posts as well regarding the battery bug.
http://forum.xda-developers.com/showthread.php?t=2090826

I guess most of the panic came from the coincidence that it shut down at the exact moment of connecting a bootable USB using a new USB OTG cable gehehe.
