[Q] nexus 7 completely dead? - Nexus 7 Q&A, Help & Troubleshooting

Hi,
I have a nexus 7 2012 and it worked fine and runs CM 12. The other day I powered it off by pressing the power button then clicking the power off option in the power menu. When I turned it back on it didn't boot up and I ended up having to hold the power button for ages. Powered if off again the next day (only use it occasionally) and when I went to turn it back on it didn't boot again. This time though no matter how long I hold the button for or leave it on charge nothing happens.
I've tried everything from trying different charging cables, plugs, plugged it into laptop, pressing power + volume down and even pressing all 3 buttons. I've popped the back off and unplugged then plugged back in the battery. Nothing works there's no sign of life at all, no screen flickers no nothing I'm stumped. Think when I powered it off it was at 15% battery if that makes a difference?
Only conclusion I can come too is that the charging port is broke or the circuit. Sadly I don't have anything I can use to try and charge it using the four pin connector at the side to test it. Only thing I haven't tried is to "jump-start" the battery. Just take out battery and strip a usb cable and plug the power wires directly into the battery for half hour but not to sure whether to do that or not and wanna make sure I have exhausted all other options before trying that.
Any ideas?

[Q] Please help Droid X won't turn on when pressing power buttom

I turned my DX off for a few minutes and now I am unable to turn it back on. I hold the power button and the screen remains black, no M logo no boot, no green LED light, no activity of any kind, just a black screen.
Battery was at 100% when I turned it off ( 20 minutes ago)
GB leak rooted working fine
Tried: Pulling battery, holding power and home buttons then the camera, volume down and power buttons with no response of any kind.
Please help.
Hold down both volume keys power and home key until you see a brief flash, then let go, can you get the bootloader screen to show up? Have you pulled the battery?
It did not work.
I pulled the battery and left out for a few minutes with no results.
I also remember that before this thing happened when I pulled the battery and plug in the wall charger the screen would show a battery icon with a question mark, now I got nothing but the black screen.
The only response that I have noticed when trying your tip is that without the battery when i plug in the charger the green led blinks once.
I am starting to feel that this is hardware related.
Keep the battery out. Plug in the WALL charger, not through USB. (yes, I know it's a USB cable that goes into a converter to use an electrical outlet; the point is, hook it up to an actual electrical outlet)
If you don't get the big battery indicator for charging coming on the screen, hit power once. Still not, hold power down a solid 5 seconds. If still no go, then you have a hardware problem. Also, try using a different USB cable just in case if this doesn't work.

I just tried your instructions by the letter and on top of that I also used a straight (non USB) charger. No response.
I have a dead fish that is going back to the store.
thanks for your help

Ghost power on during re charge

ok, the nook im using has had a tough life, and for 6 months I thought it was completely dead.
Then it came back to life and seemed to be doing well for 3 months then it started going down hill
bottom line issue: The NC seems to be turning itself on during the night while I have it plugged in and charging. Then when I unplug it in the morning its less than 50% charged.
I had cm9ICS on it and other than poor battery life everything seemed ok, someone here suggested I go back to mirage to haelp the battery so I did.
I went all the way to a full format (cache apps, everything) then started building with Mirage, everything seemed to work just fine.
Then when I went to shut down it just reboots.
So I try pressing and holding the power button in all the way, until it completely powers off, and it looks like its ok, but then this morning I got up and went to unplug it, it was already on and the battery was down at the 50% mark
I really like the NC I have 2 others at home, one fr the wife one for the child, plus I have given 3 more as gifts to friends. BUT it just is not looking good here...
any ideas would be appreciated.
thanks

Try your wifes power cable and see if it does it too.
thanks,
ive actually tried 3 of them
same thing on all of them.
now I have noticed that it only completely powers down about 1 out of every 4 tries.
If I use the soft power off option (press and hold for 5 then select power off then yes) the other times its just one big reboot
anyone had THAT?
To power off the nook when charging... attach to charger... press power button... select shut down from menu.
If you hold power button in to hard shutdown with it connected to charger... it is going to power cycle.
That is normal... and functions the same way if you put B&N stock rom on it.
dizzy
i didnt know that aboout the hard shut down when plugged in. but once again last night took 6 attempts to get it to go off and STAY off w/ the menu
any ideas?
anyone
bueller?
Are you also using the stock wall adapter? In addition to the cable you need to have sufficient output from the source you are plugging the cable into. Most older usb ports only have 0.5A output and the Nook needs ~2A usb port (usually say iPad compatible).
If the Nook is running on a low charge it will have start up and shut down issues until it is sufficiently charged. It sounds like you may have issues other than that but make sure you are getting a full charge after plugging it in overnight and go from there.
yep, matter of fact just to make sure I have tried swapping between all 3, no difference,
i may end up with a novo aurora if I cant figure this one out

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:
you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken displayā€¯ units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.
I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

[Q] My Aquos Crystal appears to be bricked after complete discharge

Hey everyone,
I don't know what happened wrong with my interaction with AQUOS, but the phone appears to be bricked.
Here's what happened.
Bought my phone from Boost, successfully switched carrier to Ting
Have been using the phone for more than a month without any problems at all
Yesterday, I left the phone without charging and it fully discharged
I plugged it to charge and came back to turn it on after a few hours later. This is when I noticed it wouldn't turn on.
I tried a couple things: holding the power button for a long time, and a hard reset (volume down button + power button). But the results were the same.
The screen doesn't turn on. While holding the power button or power + volume button, the only feedback from the phone is a series of prolonged vibrations (~10 seconds) separated by a brief pause (~1 second).
Have anyone experienced this problem?
Any advice/insight into this problem would be greatly appreciated.
I've had similiar issues with tablets where it completely drained and wouldn't charge via USB. At most it'd just give off a single vibrate and then die before even flicking on the screen. Try this, plug a USB cable in for a full 24hours before you hit the power button. Then give it a try. If it pops on to the screen where its charging after that let it get a full charge before fully powering on. Hope this helps and also hope its not due to the switch to ting.
Best of luck
PHONE OFF
This could be due to a bad usb connection. some usb when broke will actually discharge your phone or tablet so try to use a different usb. PLZ POST BACK IF THAT DIDNT WORK I HAVE MORE SOLUTIONS

Galaxy S8 Won't Charge

I have Galaxy S8, my problem is I flashed a custom ROM, and it's bricked (stuck at boot logo). I still charged my phone, and suddenly it turned off, I realized that since then my phone aren't charged. A black power logo (charging screen?) now comes up but the LED indicator for charging is not turned on while I connect my phone to charger. What I have tried:
1. Using original cable and charger. Using another cable and charger does not work too!
2. Connect it to my laptop. Does not work.
3. Use different electric socket (2-3 sockets). Still no luck.
4. Power. Not work.
5. Power + Vol Down. The device is turned off, but then the charging screen comes up again, still, I cannot power on my device.
6. Power + Vol Up + Bixby. Not work.
Is there any suggestion what should I do now? Please don't tell me it's a hardbrick. :crying::crying::crying:
Hi; try to change your charger. For me it's that the problem.
Could be that it's deeply discharged. Had that problem with my HTC one m7. I let it charge for a day and that did the job pretty well. After that, I could charge normal again.
I would try HOLDING the Volume Down + Power for at least 7 seconds.
Supposedly, this simulates pulling the battery, and gives you a few options, including rebooting or factory resetting. If you're thinking you're bricked, a factory reset might be best. Good luck.
