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 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] Nexus 4 now Hard Bricked, stock, It destroyed itself

Hello,
I have been having a few odd issues with my Nexus 4, random reboots, no sound from speakers unless a reboot. Anyway Last night I had it on charge and it started rebooting itself in a loop so I managed to break the cycle and I ended up on a screen with a android on its side with a big arrow pointing at the power button, so I pressed the power button and it rebooted and was sat on the Nexus 4 logo.
I left the phone doing that and when I came back a while later the phone was still on the Nexus logo (which was still animating) but the phone was roasting hot, I turned the phone off by holding the power button.
Anyway, now the Nexus will not turn on, when it is plugged into a power source I get a red LED for a couple of seconds and then it goes out. In device manager I have qhsusb_dload in device manager.
I have done many hours of searching, I tried a few things suggested on other posts using Ubuntu but nothing.
This was a stock device that had only ever been updated with official updates. I can send it back no problem but I thought I would try save everyone's time and effort and see if there was anything I could try.
Thanks

qhsusb_dload stands for Qualcomm high speed download mode. Theres nothing you can do, other than a jtag. Sorry

OPT Bootloop

I've looked online, especially on here, for solutions to my problem but they all seem to assume that I can access fastboot. Here is my specific problem:
I was using my phone and suddenly the screen went black. It rebooted once into the OS but immediately restarted and has been stuck in bootloop for 4.5hrs thus far. I have tried to wipe cache, enter fastboot, power down the phone but nothing worked and it kept looping. Even when I powered off. It's like the power button signal is malfunctioning because it doesn't always reboot at the same exact point in the boot cycle.
My phone is stock, no custom anything, and is encrypted. My only thought right now is to let the battery drain fully and try to boot again after that. I have not tried to enter fastboot while connected to a PC, but I have tried to do it just on the phone.
I have not been home yet so I do not have access to a PC I can actually do things with at the moment. Any help is much appreciated. Thanks!
EDIT: I am home now. Going on 6hrs of looping and nothing has changed.
EDIT 2: The battery was drained. It starts to charge but instantly tries to enter the boot loop again so the battery never gets enough charge to do anything; thus, I can do nothing to save the phone, I don't think.

If its some malfunction with power button, try to abuse the button gently. I used to do that with my Nexus 5 when its power button gets stuck inside causing bootloops.

The button itself is fine, it works as it should and is not pressed down; however, there might be some sort of internal problem causing the phone to think that it's being pressed.

Please Help! LG G2 Won't Boot Up

I had rooted my dad's lg g2( D802) and installed twrp using an app named autorec as it was recommended by many people in the internet and had very high ratings and downloads in the play store. Everything was fine for a few weeks till I noticed that the app had an update. So I flashed twrp again from the app hoping it was a newer version and it said it completed the operation successfully. Then I just used the phone for sometime and after that I switched off the phone to enter the recovery. After it switched off, I pressed the button combination for entering the recovery but nothing came up. Then I attempted to just boot the phone and kept pressing the power button but nothing came up. I even kept pressing the button for upto a minute to hard reboot it in case it was just a case of hanging but nothing came up.After that, I plugged it in for charging and attempted to boot again. After I kept pressing the power button for about 30 seconds while charging, the led blinked red 8 times, paused and repeated itself as long as I kept holding the power button.
The problem is that it even the screen doesn't turn on.
I searched for this issue and saw that many others were facing this issue. I tried the following solutions given by them which did not work:
1) Holding the power button for a long time
2) Keeping it for charging until it's full but nothing comes up and the phone got heated up very much untill I stopped it a few hours later.
3) Removing the back cover and detaching the battery power cable from the phone after after waiting for sometime, reattaching it.
My dad showed it to the lg repair centre but they told him they need to replace the whole board which is very expensive, especially considering that it is a 2+ year old phone. My dad is very angry at me and probably won't let me touch his phones ever again if I don't fix this. Please help me.
Thanks in Advance
Edit: the charge was at 45% when I switched it off. Don't think it is because of low battery

With the phone pluggged into your computer, does the computer recognize the phone? And if yes, what does Device Manager report it as being?

more info... what variant? phone does not boot.. can you press vol up then plug phone .. does download mode works... stay calmed this can be fixed..:fingers-crossed:

I haven't tried plugging it to the computer. The way to enter download mode is holding the volume up button right? Thank you for the suggestion. I'm away for a few days but I'll tell my dad to do so. I'll post what happens then. Variant is D802

OK I told him to do that. When he pressed the volume up button and then plugged it to his computer, 13 new partitions showed up in windows, and it is telling him that he needs to format the positions to use it. But nothing is coming up on the phone

Do NOT let Windows format the partitions(!)
Use the SRKTool instead to unbrick from qhsusb_bulk mode:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
Afterwards use LG Flash Tool 2014 to flash the KDZ for your variant:
http://forum.xda-developers.com/showthread.php?t=2432476
It's better to let the battery charge to full first. Shut down the phone by holding PWR button for 10 seconds, then plug charger. It should work even in bulk mode.

Did you try these simple things...
shutdown phone keeping powerbutton down.
Start pressing power button & vol down....when you see LG logo for couple seconds. Release fingers and press vol UP and vol DOWN, same time. No power button.

But the problem is, even the screen doesn't turn on while on download mode. I'll surely try out the unbrick tool but will it work since normally, the download mode screen comes up. That thing is 760mb. I think it'll take some time for it to finish. (Ultra slow internet connection )

Maybe the phone was updating and you brute force rebooted it.
If you are not DIY, you need to take the phone to a service center but that would cost money.

The Phone wasn't updating, many people are having this problem, me being one of them, here to the phone started lagging, so decided to reboot, and then It won't turn on. Tried all the tricks, ended up waiting 3 days and put it in de charger, after 5 minutes I I kept the power button pressed and it gave a sign of life, but showed the battery empty, waited 5 more minuted and tried again. This time it turned on, after a week exactly the same problem, after 3 days I could start it with the same procedure, at this time there was an update, installed the update, and tried to restart, it now turns off, does start, but I don~t have to wait dthe three days., after some time I can start it manually again, but it is a clear problem with the phone. ANd I expect it to be software related.

Phones have become complicated like computers, the phone was lagging because it was doing something for sure then you shut it down.
If you're able to turn the phone ON, I suggest you STOP trying wrong moves and do a hard reset.

Ok, last time I succeeded in turning on my phone, I went I to updates and feedback and send message with the logs of my phone. Today I got a reply, they have determined that it is the motherboard and they adviced me to take it to the nearest deviceocation and have it checked out

Your option was to "hard reset" the phone and that is what any repair shop will try as a first step.
Don't waste your time with incompetent and misleading scammers' replays because no shop will waste time checking a motherboard unless it's a $1,000+ phone BUT they will replace it anyways, they don't waste time checking it.
And do you have a Xiaomi or Poco service center near you?? LOL
I also sent a message and the logs to updates and feedback but they never replayed back, they also both Xiaomi and Poco NEVER replayed back to my e-mails and requests made on their Facebook pages, that means these companies are crooks and scammers.

Look at this thread...

What worked for me was waiting a few days to drain batter, then when I plug in and there is a charge icon I just wait and after a while(5 minutes or something) poco logo appears and after that when it goes back to battery icon I click volume buttons like crazy so it won't die, then when it shows one percent I hold power button while still clicking volume and it shows poco again(stop clicking now). It then shows miui and works fine
