[Q] Mt4G won't boot AT ALL

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.

Nexus 4 wont turn on

Hey everyone, Im having a problem thats making me worry. I was using my phone today and for some reason the phone wont turn on after I turned it off. I havent dropped the phone at all and it hasnt been abused in any way. The last thing I was doing before I turned it off was trying to send feedback for the Yahoo Mail app because it wouldnt sync automatically, but even that was unsuccessful because it wouldnt send. So I thought I should just reboot it but afterwards its not turning on at all.
I tried holding the power button for at least 20 seconds and still nothing is happening, and I tried plugging in the power cord to see if that would help but it hasnt. Has anyone gone through a similar issue? Please Help
Thanks.

Leave it plugged in for fifteen minutes without touching it.

Try holding volume up + power to see if you can get into recovery then reboot from there.
Also, give some more details about your setup...
Rooted/Stock/What Rom/Kernel?

Yea I left it alone for a bit and then I held the power button while holding down both volume rockers and somehow it turned on. I dont know why this happened but I'm just glad it turned back on, it gave me a good scare though. I just hope it doesnt happen again

Mine is completely stock, I havent done anything with it yet

And may I ask what was your battery percentage level like after the short charge? Maybe the phone drained it all just being turned off... There were some cases of this here...

i wanted to add that i had a similar problem with my phone not turning back on. However, I managed to fix what was wrong by just plugging in the usb cable. I know you've tried it, but just in case someone else stumbles upon this thread (like me!) and has a problem turning on their nexus, I wanted to share my experience.
I haven't done anything to my phone other than add my old apps to my Nexus since I received it 1.5 weeks ago. It's stock. I've never dropped it or gotten water on it or anything. I charged it overnight last night and stuck it in my purse on the way to work. I think I briefly saw a working screen after I unplugged it this morning. However, the first time I tried to access my phone today was after I got to work. It wouldn't turn on, though that pinkish light at the bottom was still blinking. I tried calling it and the Nexus wouldn't ring even though the call went through a few rings and then onto voicemail. I tried holding down the power button for a while and also holding the power button with the volume keys to see if that would work, and it did not. Finally I borrowed a usb cable to plug it in, hoping the jolt of power would wake it up. That worked. It gave me the charging symbol for a little bit and then gave me the startup/loading screen with the glowing x made of arrows. I checked my battery and it was at full charge. Well, it was at 85%, which is odd since I plugged it in for about 9 hours last night to charge and there has only been 3 hours of non-use since I unplugged it. Also, if it was really turned off during those 3 hours it shouldn't have ate up any battery. Anyway, I just wanted to throw in my 2 cents in case anyone else has this problem. My brother, who gave me the Nexus, told me that he only has 2 weeks to return it if there's something wrong with it or I don't like it. Needless to say this gave me a scare, since the 2 weeks is almost up.

Yes this happened to me the other night. I was making a phone call and accidentally hit the power button. I then tried to turn the screen back on in order to hang up the phone and it would work. I tried holding the button for 15 seconds, tried pressing the volume up/down keys, and still nothing. I then put it back in my pocket for a minute or so and tried again. When I did that the screen came back on and the call was still active. Very strange, and I hope it doesnt happen again....

Same thing is happening to me right now.
Running stock. Not rooted. Phone charge was around 70% and I was on twitter and the app force closed. So I decided to restart my phone then went to turn it back on and it wont respond. Tried holding down the power button for 20 sec. Volume up and power, volume down and all 3 at the same time. Still nothing. Leaving it on the charger for awhile and the screen is blank no battery logo or anything.
Not quite sure what to do now?

That's scary

I get the same. I use Dophin Browser . After that i reboot my Nexus 4.
I try to hold Power Button for 1 minutes or more. But nothing change. I
I try hold Power + Volum Down - or Volum + but get same result.
I plug in Adater and wait for it. I will check it 2 hour later.
My Nexus 4 use Stock Rom, Rooted. and this first i get this problem. Please advise me on this case. Thank
:laugh:

I'm having similar problems. Lots of random rebooting and refusals to turn back on sometimes, even though the LED at the bottom is flashing so i know the phone is still powered up. Also, sometimes when i have it plugged into a computer through usb it will get extremely hot and completely shut down, not turning back on for a long time. I called the google play store and someone is going to get back to me. I love my nexus 4 so i hope i can get this fixed or a replacement.

Nexus 4 crashed and would not power on

I had this issue too a couple of times playing Pandora through my car's Bluetooth. That was when the Nexus 4 had 4.2.1. I have not had this issue with Pandora since the upgrade to 4.2.2.
However, I just now had this issue with Movie Studio app and exporting a video I edited. It turned off its screen like normal screen timeout but then would not come back on.
I had to Volume Up + Power button for a few seconds and then release to get it to reboot.

This same thing is happening to me. Haven't found a specific cause...

Just got the same issue
Today got mine not turning on.
Managed to turn it on by holding volume up and power button together for about 30 seconds while phone was on a stock charger. After that I saw blinking orange led. When I resolved buttons there was a battery pictogram. After pressing and holding power button I finally got turning on vibration and Google logo.
The only things a made after the charging were making few photos of my cat (from the lock screen) viewing them in gallery. Then I locked the screen and put the phone on a shelf. In a hour I was not able to turn it on.
My phone has stock rom and only few third party apps installed.
I got muy Nexus 4 on 21-Dec-2012. 4 days ago I flashed to Android 4.2.2 which phone dowloaded itself. After flashing phone was rebooted.
What I noticed is that it shows 70% battery. But It was fully charged few hours ago.
30% in 2 hours! In my opinion some service/app drained these 30% by using 100% of processing power that caused overheating and/or hanging.

I too have just had this problem. And I've had it previously when making calls, the screen simply won't respond at all, its quite annoying.
This morning my alarm went off and the screen wouldn't turn on, it went on for so long I almost threw the phone across the room. I eventually held the power button and volume down/up button and then the led blinked orange a few times and the phone reset, now it seems fine.
Its a very annoying problem, and could be very serious depending on what you are doing, might have to phone the play store and tell them.

This has happened to me twice now. First time was a month ago and the second time was this morning. Phone was at 100% just woke up checked my messages turned off phone 10 min later it will not turn on. Un plugged cord re plugged cord nothing finally pressed up/down vol and power for about a minute (long minute) and the phone rebooted. YIKES!
Every thing seems normal now but I hate that scare and the fact that it has happened to me twice. Full Stock, not rooted.

Happened second time.
I was able to turn it on again by following the same steps. But this time I got some strange issue: after resolving vol+ and power buttons I saw battery pictogram with some frame with a blue background; when phone finally booted up this frame and blue background were visible through the my desktop background an screen itself was much lighter with pure colors. Only after about 5 soft resets screen seems to became nice again. Each reboot caused blue frame to become less visible. I'm confused and worried.
Also during all these reboots this frame with blue background was visible even in behind "Google" and "X" logos during booting up.
Another strange thing is that on screenshots I made this frame is not visible.

That would have to do with LCD or software..
As the battery & Google are just pictures that change. If you understand what in saying lol ?

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?

I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...

Have you tried pulling the battery for a couple of minutes?
Sent from my Nexus 7 using Tapatalk HD

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.

You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.

Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.

I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.

How did that 'fixing itself' happened to you if i may ask? And how long did it last?

Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.

You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

[Q] N4 only turns on when charging

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?

[Q] Is my Nexus 4 dead? What can I do to recover it?

Hi,
A few days ago my nexus 4 stopped working on me, I haven't found anyone having an identical issue so far.
Essentially, my phone does not turn on any more. I have tried holding volume down and power and this produces nothing. The only thing I can get is the red LED turning on if I hold power for about 10 seconds with it plugged in, it lingers a bit if I release power., but immediately turns off if unplugged.
It stopped working while it was plugged in and at about 60% battery, I had not had any problems with the device in the past, it worked flawlessly up to that moment. The device was running stock without any third party firmware.
Does anyone know what happened, and what I can do about it? I somewhat suspect a battery issue but I'm not sure, any help would be appreciated.
Thanks!

Hi, I'm having the exact same issue. My Nexus 4 (stock Lollipop 5.0, not rooted) died while the battery was 80% full, and the phone was charging. Shortly before it died, it restarted several times within a few hours. The phone doesn't respond to power button, neither it responds to power/volume button combination. When the phone is connected to a charger, nothing happens - no LED, no screen. If the phone is connected to a charger, and I press the power button (or power/volume) for >10s, LED starts blinking in red. The blinking pattern is weird - it blinks steadily 10 times, and gives one short blink. Any suggestions? Or any hope to get the data out?

You can possibly fix this by holding either power up or down for 15+ seconds and then connect the phone to a computer with USB. This has worked for me.
The problem might be that the battery is dying, because I've only had this problem when I've let the battery discharge, and then turned it on again. It's probably a mechanism to protect the battery from becoming "too" discharged, which might break it.

Everytime I had this in the past, I was able to fix by plugging into a very high powered charger (1000mA <) and holding down vol up + power. Eventually, it seems to trickle charge and then start. Once it's started, give it 20 seconds to get a boost then switch it on.
