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 display” 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.
Yesterday my phone died. I started the tom tom application, the screen froze. Pressed the power button for some seconds, phone turns off. No success trying to turn the phone back on. It was plugged in to a car charger.
The phone has been attached to a wall charger for >10 hours. The phone just looks dead, when it's plugged in and I press the vol down + power button I get a blinking red light after about 15 seconds, but notting happens.
Is my phone officially dead?
Red light doesn't necessarily mean your phone is dead. Maybe it's a problem with the battery, some users have solved the problem removing the back cover.

RMA it and get another one
Couldn't find any response or anyone with the same problem here. If it's the right place. Please, let me now.
I only can use it when it's plugged at the wall charger. And sometimes I can enter fastboot and recovery using the laptop. When I take out the cable, it dies again.
Tryed all stock versions (4.2, 4.3, 4.4 and 4.4.2) and all the same.
Tryed three new batteries and then go from 0 to 100% in one minute the go back to 0 and starts charging again.
I noticed that every time I try a new battery, it show the red led, and to start charging, I must hold power 10-15 sec then i can see the battery icon with the flashlight then charging. But when I press power after 15 hours of charging, the red light appears again. So i keep pressing and it turns on, but with the same result.
Any idea?
PD. Sorry about my english.

I am curious, how are you able to so easily swap out the batteries?
Has it always behaved like this (from new), randomly one day or after you changed something for example ROM, Kernel, some hardware etc?

After the first one, you are able to open and close it in 2 min.
One day it turned off and never woke up again. :crying:
Nobody? I'm about to put it in the garbage.
I've got a similar issue to the OP, I can force my phone to start, and have left it to "charge", but as soon as i disconnect the charger, the battery percentage goes down about 20%. if i then turn the phone off, I get a solid red notification light for about a second. to get the phone to turn on, i hold down the power and volume down buttons. If i hold down the power and volume up buttons, it appears to start charging, but never actually does. Any suggestions on how to get it to charge?
Hi,

Can you turn your device on? If you plug in the charging cable, did it charge? And what about bootloader mode?

Nothing :/
the device wont turn on, the device wont charge (i have tried different socket/desktops, and also different chargers), and i cant boot into bootloader / recovey mode.
Note: when i performed the steps on the internet, when i plugged in the cable, the Red LED light in turning on for about 15-20 seconds, and then turning off.
what can i do except for going to a lab?

You can try this, if you didn't have already:
- Plug your phone to the charger while holding down the volume down button. Your device should boot into bootloader mode.
- If the above doesn't work, then let your phone charge for half an hour and try it again.

i have tried it and it didn't worked.

also, when i tried you steps, the Red LED blinked a few times when i inserted the cable in, and then its turned off.

When you plug the cable in, you must press down the volume down button simultaneously. Not just only plug the cable in.

Is the LED always on or only when you plug in the charging cable. I may have a slightly presumption...

since the LED truned on i didn't disconnected the cable from the device, and the LED didn't turned off.
i dont know if to remove the cable right now, because if it is finally charging, i dont want to stop it and mess it up again.
so what now?
edit: i didn't disconnected the cable yet. but the Red LED turned off.

You are charging from the electrical outlet, are you?
Just let it charge for at least two hours, it is a good sign that the LED went on.
Furthermore this red LED also known as 'red light of death' is a common issue of Nexus devices. It's an indicator for the batterie not to charge or because there was a thermal shutdown cause by too much heat and you only can solve this by screw off your device.
I hope you dont must go this far. Just be patient and wait what happens after the charging period.

i have just noticed that the phonr is not charging at all.
its like before the Red LED turned on for a few minutes..
Did you also try to charge it with another cable? Try again to press down volume down key and plug in the cable.
By 'not charging at all' do you mean, there isnt this batterie logo when charging?
Edit: Try this volume-down-plug-in-cable a couple of time. It may not work the first time you do it.

search "red light of death".
leaving it on the charger might fix it. taking off the back cover, disconnecting the battery, then reconnecting the battery is an almost 100% fix.
Hello,
I was on a phone call earlier today and my 6P (Nougat 7.0 stock, EX kernel, 90% off charge before the call) turned itself OFF and the notification light was blinking red. I tried starting it as usual, using the power button, to no avail. I tried plugging it in to the OEM power cable, also to no avail. I plugged it into my computer using the OEM USB cable; still nothing. Nothing I did would elicit any response from the phone at all. I checked online, and tried power button plus down volume technique. Nothing. Even after keeping it connected to the stock OEM charger for more than an hour, the screen is still blank and notification light is still blinking red.
Q: Is the battery or motherboard dead? Should I leave it for an over night charge and see if it boots backup? Or should I RMA it without warranty?
Any help on this would be extremely helpful.
I have only had that issue once where the phone said 40% but suddenly died and blinky red light but plugged it in and then screen flashed that it needed charging then was able to turn it on after a minute. Maybe your charger is not working or that you need to RMA if you have rooted your phone or anything I've never had an issue of it destroying warranty. With Nexus or HTC.

I did an RMA and sadly, no I couldn't find out what went wrong. If your device has the R.O.D I suggest you RMA it.

My Nexus 6P did the same thing... Just turned off and the notification light blinked red. I can't turn it on. Charging seems to work since current is passing to the phone (via USB current meter). But won't turn on. In your post, what is R. O. D.? Did you ever figure out what went wrong? Should I get a technician to look at it or just buy a new phone? My warranty expired about a month ago and Huawei wont do anything for me. Thanks
FWIW - i fixed mine...
Perhaps different set of variables but i woke to find my 6p doing the red blink shuffle. power button, 2 blinks i believe, plug to charge, constant blinking.
what worked for me- unplugged, help vol + and power for 15 seconds, blinked once maybe 10seconds in. afterwards, plugged to power, showed charging icon, no blinks. let it charge and all was back to normal. (this is with unlocked bootloader, not sure on other specs as it was a backup device and i have forgotten. when i get home, if anyone requires, i can post exacts on it, though doubt it will be necessary)

I have the same issue but tried the steps you said and no dice. I even took it to a local service center recommended on Hauwei's website and they didn't have a clue. Any recommendations on where to sell it for parts?

Literally the same thing happened to me. Constant blinking, when I hold down the power button 2 blinks. *Heart Attack* This frickin happening 2 days before my holiday, but doing what you've said above worked. Observing it going from 0% to 9% in the bootloader as I type this.
Could this be a symptom of something worse? Like the charger part of the motherboard giving out? Because I've had this phone on charge for a few good hours through the night, where it managed to die and stop charging.
old thread here. but just to add to it for any new folks that come across this problem. I bought a new battery and replaced it. And still only get the red light of death. So it has to be something other than the battery.
Same for me, new charge board and new battery and no change.
The power and volume trick doesn't work for me.
If I plug the charger in the red light stops blinking but it still doesn't turn on.
If I leave it unplugged for long enough it goes back to the red light blink so it's obviously draining the battery even thought it doesn't appear to be powered up.
This only happened to me once. Battery died and the phone shut down. Charged it for an hour on oem charger and it would only flash the red light. I had to charge it from my laptop usb port and for some reason that did the trick
