My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).
Used my device last night to do some reading and the battery was about half full.
Went to use it tonight, won't turn on. Thought something killed the battery, so charged it for an hour.
Held power button, nothing. Tried volume up then power, nothing. Finally got it to do something by pressing volume down and power. It comes up to the Odin screen.
I've never rooted/loaded any roms or anything, so anybody have any idea what the heck happened or how to get my device back to normal?
Thanks for any help.
Have you used the stock AC wall-charger to charge it up?
Yes, it's charging now while I am reading all about using Odin and downloading a stock firmware...
Not that I know what I'm doing <grin> I'm hoping it powers up after I charge it some more before I go mucking with it...
Thanks, Samsung! I'd much rather be having this fun instead of reading a book. Where is the damn ICS update? Honeycomb sucks.
I would let the battery go flat which is the same as removing the battery on a phone and hope that allows you to re-boot normally after charging then I would try a factory reset to clear any problems before going down the re-flashing road.
Well, looks like letting the battery go flat is my only option because after charging all night it now won't even go into Odin Mode.
Do you have a general idea how long it will take for the battery to die since there are no indicators? Should I expect days/weeks?
Sure wish I could pull the battery or use the paperclip trick like on other devices. This thing is a very expensive (imported) paperweight right now.
EDIT: Any idea why I couldn't get to the boot loader (volume up + power) to reset the device but the Odin mode worked?? I don't think it's the button, this device has been coddled. Just sits on my nightstand until I read a little at night and put it back.
Uh 九千., I'd thank you twice if I could.
So I go to pull the usb cable and wall charger behind my nightstand to bring to work and it's NOT the original charger. I forgot it came with the European power adapter so I had to use a generic USB charger.
I grabbed the Samsung wall plug from my 8.9 and now it shows the battery with a yellow exclamation mark. I'll try charging it and go from there.
Very strange, considering I've been using the other usb wall charger since I bought the device maybe six months ago...
I'm hoping for the best!
EDIT: IT BOOTED and it's charging... What a relief. Thanks for the help guys.
EDIT 2: So before, it was NOT charging... It got so low that only the Samsung wall charger could get it going??? Very strange.
So I was using the new Hangout app to video chat, ignored the 4% battery warning, and eventually the phone shut off due to low battery.
After that I attempted to charge it all night, using various USB cables, wall units, the charging orb, and without, and a PC, and nothing happened after leaving it all night.
Holding the power button does nothing, trying to load the bootloader nothing, and holding both volume buttons and power does nothing. Simply unable to boot it or turn it anyway on.
Plugged into the PC also shows nothing.
I called google and requested an RMA, but I'd like to see if there was a way to backup some pictures from it.
Is there any known solution for this? I feel like the battery died beyond the point of no return or something.

It is really drained then... You can fix it by Manually applying current to it so it can charge a little. That's the only fix I can think of. And if I remember correctly there is a thread here on XDA which demonstrates the procedure.
Charge it for 5 mins, unplug it, then plug it back in.
I heard an answer to this somewhere, if you browse the N4 forums for a while you might find it, bit I think it was charge it for a few hours via normal USB, then hold power for 30 seconds to a minute? You might need to charge it for a few hours again after and hold power for 30s again. Good luck

Same thing Happened to me.. it died overnight and I plugged it in in the morning and now I checked a few hours later and it didn't charge! Wont turn on, I've tried various button combos and different chargers and cables.. Help!!!
I'm alive! Phew. So After trying all the combos with it plugged in.. I eventually waited an hour or 2 hoping it would charge.. and then tried the same thing after unplugging it ( after giving up and running out of ideas). With the phone unplugged I did power+volumne down and within a few seconds I felt a buzz and got into the bootloader.. then I rebooted. Phone booted up but battery was at 0 so it shut off instantly. But now when i connected the charger back I got the battery icon - Yay, it started charging!
This worked for me so just putting it out there in case it can help someone else

Yea, I got it working the same way also, why is it so iffy? The phone shouldn't even need a battery to boot if it's plugged in.
It should be able to bypass the battery power check to USB, and charge the battery in the meantime.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!
I'm currently having the same issue, haven't used it in 6 months and when I tried to turn it on, nothing happens

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.

I would be more than happy to take it off of your hands mate. Probably gonna use it for parts to keep mine running.
So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry
You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.
Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...
