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.

I think my N10 just died.......

Hi All,
I was browsing the web a couple of hours ago and my N10's screen started flashing on/off and after around 10secs the thing crashed/turned itself off. Being an N10 this was not an unusual event! However when I try to turn it back on nothing happens. I can hold the power button / power button with volume buttons pressed and nothing happens. If I plug it in to charge I do not get even get a charging icon.
If it makes any difference I was running the latest Rasaber with Franco's r11 kernel and I know I had at least 40% battery left when it died. I have left it plugged in to the stock charger for around an hour hoping that something might happen but still nothing.
Has anyone ever experienced anything like this?
There was not a sad enough looking Emoticon to convey my sadness over the possibility my lovely Manta is dead......

no man ... it s impossible . nexus 10 its the best device ever . acording to some gurus here
your device its dead . now you have to stay on your knees to google replace it . good luck

Something similar happened to me but I'm totally stock. I Googled and the solution was to recharge the unit via my PC USB instead of plugging it into an outlet. I have no idea what happened but after a few hours of being connected to my PC it was back and working. Hope that helps.

I'm running the same rom and kernel combo. No problems or anything weird happened. It must be hardware related.

Did you try the holding-the-power-button-for-a-minute routine?

I would try to leave it plugged in on the charger for a while and see if it gets fixed. That usually solves all sorts of "wont turn on" problems

is it possible for the tablet to get overheated?

I have had that happen on stock.
My theory: it is linked to the 'battery status not updating'-bug. Your Nexus thinks the tank is still half full, while in fact you are running on fumes. It does not realize this, so no dimming of screen, no low power warning, it just goes full steam ahead, until the battery is totally and utterly and completely depleted.
Then, obviously, it won't start but it will also have trouble charging. You need to charge it for quite some time, sometimes try a different charger, and sometimes keep the power button depressed for a full minute for it to come back to life.
Now when I use my Nexus, I keep an eye on the battery status. If it does not go down, I know I need to reboot for the battery status to be read properly again. It is a bit of a bother, but not too much. The bug only kicks in after the tab has been lying around for a while sleeping. So if I want to watch a movie, I first reboot. As long as I keep using the tab (i.e.watching the movie), the bug won't 'activate' and the tab will shut off properly when it senses the battery is low, in stead of continuing and deep depleting the battery.

My Nexus 7 is doomed...

A few weeks ago, i flashed a stock rom on my wifi nexus. I was happy with it until last week. Charging became incredibly slow - 30% over 8 hours. I threw it in my bag and wheb i got home 8 hours later, the battery was depleted completely. I couldn't turn it on. I plugged it in over night and it stayed at zero percent. I booted into recovery and reflashed my stock rom abd wiped my data. Still didn't charge. I tried going into my bootloader and hitting power off and then plugging in, but it still wouldn't charge. I can't flash my backup because it's on my card that i lost, and even if i had it, i wouldn't be able to keep it on long enough to flash it. ADB won't run on my pc and i don't know how to use the program anyway. What can i do to save my device? Please help.....

Not the average flasher knows how to tear apart a device - including myself. Anyways, this thing won't power up at all? You tried leaving it plugged in and booted into bootloader? If so, sounds like a hardware issue or the battery is defective.

I would be willing to bet that your battery connection came loose. Start at your USB port with a thin piece of plastic, such as a guitar pic. Work your way around the device and remove the back.

Sounds like my device... only I even can't get into the bootloader nothing... Someone suggested that the battery got so far depleted that it will nor recharge.
However seems you at least can run the bootloader... for me it just stays black ..... nothing nopes nadda

I heard that was a good site. I'm more scared of screwing up any hardware than doing the actually tearing apart.

I can boot for like 30 seconds and then it shuts off. I've tried the solutions in the thread link above; however, i still think it is a software issue. I've used other roms that had really slow charging, but i was able to switch to another one before the battery got depleted. So i think my best bet is to somehow get a new rom on my device somehow. ADB won't run on my computer. It just flashes a command prompt on the screen for like half a second and closes.

What kernel are you on? The kernel is what does the charging operations.

I had a similar situation in that after the battery died, I got it to the point where I could boot up, but after a screen timeout, it would be dead again. Finally, I got it booted again (while plugged into power) and immediately went to developer options and checked the Stay Awake, never sleep while charging. Keeping the screen awake kept the N7 on and it charged up.

Funny my Galaxy Nexus started doing this crap on me too after I updated the rom and kernel. The phone and battery are only 2 months old replaced in April.
Occasionally it won't take a charge. I have to **** with the battery, removing it several times. Then all of a sudden it starts charging again after 10-15 resets.
Haven't had a problem in a while. Typically hits me like every 2 weeks.
No problem on N7 though but it happens. First thing is to change your kernel and rom to something else. If still draining, flash stock and relock, unlock, relock, wipe. Boot, upgrade to 4.2.2 and test.

[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.

Touchscreen dead on wake, reboot fixes

Anyone got an issue where after some time (can be one week plus), you pick up your tab and the touchscreen is completely unresponsive on the lockscreen, can't even press powermenu? Reboot fixes. I had it on JSS1J and persists into JSS1Q. Hard to isolate as it may not happen for say a week of uptime, seems to be no pattern or consistent trigger

I been getting the same thing. Charging over night the tablet wakes but touch is unresponsive. I'm on Clean rom and Elementalx kernel. Yesterday morning after 8 hours on battery and unused it woke and touch was fine. This morning after 6 hours on charger, over night, it woke and touch is fine. Need more testing.
Note: yesterday afternoon I update Elementalx kernal to 1.3

Yeah elemental or stock it happens

I see this from time to time on mine. What sucks the most is when the damn alarm is going off and I can't do anything but hold the power down to reboot. Wife loves this "feature" in the early AM.
I have an unlocked bootloader but I'm running stock kernel (3.4.0-g6537a16) and stock JSS15Q. I do see random reboots as well, seems to be related to the screen going to sleep by itself but I can't reliably reproduce it.

Happens to me as well. Annoying.

I had this on stock locked so its nothing to do with bootloader or custom kernel/ROM.
Curious if a CM based ROM will affect this i.e. not stock JSS1Q based.

Is everybody facing this touchscreen issue? I am planning to get the new nexus 7 2nd Gen from canada. Is it something you can discover in the first week itself because the person who is bringing it will get the tab a week before her return.

If you're lucky it'll show up in that time period.
Others have gone 10 days.
Have them put off buying until the last second....

Same thing happening to me. The screen becomes unresponsive. Happens in the morning when the alarm is going off and have to reboot. I just updated to ElementalX 1.4 and hoping it'll fix it. I'm hoping Google comes out with an update soon because my screen sensitivity sucks sometimes. It's not registering my taps.

It doesn't lol it's either hardware or something in 4.3base

My one, after 10 days, dead, the touch screen has no response at all
sent back to repair for over 1 week, still no news on when can return..
really bad feeling with this Nexus 7 (2013),
only Nexus 4/7/10 has no problem and still working well till now.

I faced this as well. But it solves itself.

I experienced the same issue here. However, I am not able to reboot as I am still running on stock and don't have the debug option enabled. Pushing the power bottun for some time only brings up a menu where i may chosse to shut down. As the touchscreen is not working, I cannot do anything. Unfortunately, my battery is almost completely charged. Any ideas how to reboot?
Coincidence: The touchscren went unresponsive after the alarm clock went off. Maybe there is a connection?

Here's hoping JSS15R fixes this (fat chance hah)

Hold down the power button until it reboots.
I had this issue exactly once since I got mine, and it's been fine since. I suspect it's a hardware or driver issue.
