the last couple of days I've been doing fairly CPU-intensive things like rebuilding the dalvik cache, installing many apps one after another etc. What happens is that the phone gets really hot then just shuts down.
Then I get a red (solid) light if charging. Holding vol+ & power or vol- & power to boot doesn't do anything, I have to open the casing and disconnect and re-connect the battery then it just boots fine.
I found today that if I plug the USB cable into a PC (instead of a wall wart) that I can get into recovery (vol+ & power) or download mode (vol+ & vol- & power) but it only appears for a moment then turns off again and goes back to the solid red light requiring the battery to be disconnected/reconnected.
I've opened the phone 3 times in 2 days to get it to boot up and It's getting tiresome.
Also I've managed to get the phone to stay on the battery icon (not the animated one, the one with the lightning bolt) by doing into download mode and then letting the phone reboot while connected to a PC via USB.
The battery is never flat, once I reconnect the battery the phone indicates it's got a good charge (which seems accurate, ie. it say 40% and lasts several hours after reconnecting)
when i rebuild cache after update or something, i put the phone above a cool surface, otherwise it will warm a lot

I went out for a while with my battery at 20%, when I came back it had drained out. I put it to charge, but when I tried to switch it back on, it refused to boot. On a normal power button press, it would vibrate 3 times and then the red notification light would start blinking. Same thing with power + volume_up. If I press power + volume_down, it would vibrate 5 times and the green notification light would stay lit. Nothing comes on the screen, whatsoever.
I was rooted with S=off, and was using the Operation Inferno ROM (which I have been using comfortably for the past month or so).
I did try some stuff with ADB, such as using it to reboot into bootloader and recovery (same 3 vibrate + red notification light), pushed the Operation Inferno ROM again to the sdcard and tried to restore the ROM from that location (for which I got adb: unable to open file /sdcard/backup.zip).
I haven't yet gotten around to downloading and installing the factory image some have suggested for the eMMC issue (PD15IMG.ZIP) but I wanted additional opinions considering most people with an eMMC issue have been able to open HBOOT at least.
When the phone doesn't power on, neither ADB nor fastboot will help you. There is no device on the other side, so all your attempts went to the drain, and it was expected. Nothing to do with eMMC issue or anything else. Your phone just doesn't power on.
Put your phone to charge, if the light turns orange - just leave it to charge until it's green, then disconnect and try to power on.
If the light doesn't turn orange, or it doesn't power on even after charging - remove the battery for 10 min, press Power button for 1/2 min, release the button, reinsert the battery, put to charge. And again, let it charge before you try to turn it on.
I did charge it earlier (for about half an hour or so) and the orange light does come, but it didn't boot after that either.
I'll just give it a try by charging it through the night and see.
I think a key thing is to take out your battery for 10 min, as Jack_R1 suggested. Then proceed with the charging.

Still doesn't work. I dissembled it and kept it like that for quite some time, then put everything back and charged it for hours. Still the same issue happening during boot.
Connect the phone to USB, powered off, see if the PC recognizes "QHSUSB_DLOAD" device. Try to power it on, see if it happens.
If it happens - it means your primary bootloader is screwed, in another words - no repair (actually, repair is theoretically possible, but no guide, no information and no sources exist for MT4G).

When its plugged in, its recognised by the ADB (even when powered off), and I can do some basic commands (mentioned in the first post). When I power it on the same thing happens as when it wasn't plugged into USB (ie, the vibration and the blinking LED).
I'm also worried about water damage, since a very tiny amount did come on it as I was sweating profusely. Although the indicators in the battery tray and on the battery itself don't signal damage (they're completely white) I've just decided to try and keep it opened up in a bowl of rice, just in case, until someone is able to come out with some idea.
As I'm in India, taking it to T-Mobile is not an option. If nothing works out, I might take it to HTC and see if they can help out.
Hi, so I've been doing a fair bit of reading, but I've not really found anything thats exactly like my issue.
So I got the Nexus 4 yesterday, today I've been using it for probably 3 hours, it was charged overnight last night to 100% and was still at about 65% when the phone randomly rebooted, no force close or anything. So it attempted to boot back up, showed the Google logo and then the nexus X, before going to a black screen.
From here I can't turn it back on, I've tried:
Power - up to 60 seconds
Power + Vol Up - up to 30 seconds
Power + Both Vol - up to 60 seconds
I then plugged it in to the wall (using the charger provided), there is no sign of life still, no battery charging screen, no flashing red led.
If I hold down the power button, while the phone is on charge, I do get the flashing red led.
Is this a case of leaving it to charge and assuming the battery is completely drained, or should I be contacting Google to start an RMA?
Should probably say, as I've only had it a day, no root, no custom rom, everything stock and on 4.2.2
Thanks.
Hi guys,
My battery went completely dead, left it to charge over night, now wont boot at all. If its plugged into the charger and I hold the power button the full battery symbol (black and white) shows for about 2 seconds and then goes off for about the same time then reapers. Any ideas?
Device status:
- Stock rom
- boot loader unlocked
- non-rooted
I've tried :
- Hold power for 30 seconds to a minute
- Hold power + volume buttons for 30 seconds to a minute
- no response form my computer when its plugged in
- no response when trying to boot into fast boot
I am aware this has already been asked. I've tried the other threads but no luck
EDIT
I got mine to boot. I have literally no idea how, I just tried the power button again and it burst into life, although the battery was empty.
I think this could be due to not letting the battery die enough. I normally let my phone (HTC One) so completely flat every month or so but i've never done it for the Nexus 10.
The same problem please help
Serious bump. Ive tried all of these methods, but it just shows the charge icon when plugged in. This is the first time for me that it wouldnt just turn on after going into that sleep state. Charged over night.

I think this is the same issue that many (or a few) people are having. Mine, for example, will be at 100% charge. Then, sometime in the day (without using it) it will die. It will not power on. When I plug it into a charger, it will show the charge indicator on the screen, and I can get it to power on 50% of the time right away by holding down the power button for about 5-10 seconds.
When it boots up, the android tells me it is at 0% battery. If I leave it plugged in it will usually show 100% again after a short period of time, but until then, if i unplug it, the tablet powers right off.

Here is a pretty good thread to see the issue.

Here's a question for you:
Watch your battery life. At any point, does it begin NOT draining? Such as remaining at 60% for 2-3 hours during usage? If so, you may have a defective motherboard and require warranty replacement, as that was one of my symptoms.
I had dropped my phone in water, instantly took it and put it into rice, waited about 3 days and took it out. It won't turn on
I can plug the USB cable in, and the image that shows a dead battery with a lightning bolt inside it ( charging ) flashes on for about 2-3 seconds, and then quickly fades out and it will just constantly do that for as long as it is plugged in.
Holding Vol Up, Home, Power, flashes the Galaxy S6 Android screen , and then dies.
Holding Vol Down, Home, Power, I am able to get it into Download Mode, but not sure what to do from there.
Ideally all I would like to do is backup my pictures, and contacts from the device.. I already have a new s6 edge, but unfortunately my contacts and pictures were not synced to google at all.
Any suggestions? Any way to somehow retrieve the data from the internal memory ? Or replacing the battery somehow?
Hi all,
I'm struggling with getting my 2012 Nexus 7 to start and hope someone out there can help!
I think I may have let the battery become discharged, but anyway here are the symptoms:
Connected the power lead and the tablet initially showed the empty battery icon but then started to flash up the word Google but does not boot up. Left it connected for a couple of hours. Still no joy.
Did a bit of internet research in an attempt to reset the tablet via the button combinations.
With the power lead disconnected, holding on/off plus volume+ together eventually gives a blank screen and from there holding on/off plus vol- gives the Android figure with its belly open. Hitting vol+ scrolls thru the four options of start / power off / recovery mode / restart bootloader, however when I select 'recovery mode' and press the on/off button instead of showing the Android with a red triangle it simply goes back to flashing 'Google'.
From there, if I press and hold on/off and vol- for several seconds the screen gives a momentary blue flash and then the fours 'dancing blobs' appear, eventually to be replaced with the flashing 'Google' but still no boot up.
If I connect the power lead although I can get the initial Android figure, I cannot scoll for any of the options.
All of this sounds like a major fault, but funnily enough yesterday evening I left the tablet with a blank screen and disconnected only to find this morning that it had booted and had all my apps showing, all of which appeared to be working properly. so I connected the charge lead and it said I had 17% battery remaining however the battery charge graph showed a number of major gaps and also showed the wrong date (2 days behind). So I connected the power lead and left it for 10 mins to find that the charge state hadn't moved but also that the screen brightness was reduced as if it wasn't connected. So I unplugged and then re-plugged the power lead and it said it was optimising 1 of 2 apps then the screen brightness returned to full, any appearing to function ok.
So left if for around 30 mins at which point the charge had gone up to 21% and I decided to try switching it off. Bad move!! Instead of booting up it simply returned to the flashing 'Google'. Which is about where the story started.
I've had the back off and the battery connector hasn't shifted, but one thing I did notice is that there is a fourth key switch below the vol- switch but without a hole in the cover to actuate it when assembled. Is this part of the button-press combination to restore factory seetings with the back off ??
If anyone out there can make sense of what the tablet is doing, I'd love to hear from you!!
Mike
