*HELP* Nexus 5 unresponsive, any help appreciated

I recently purchased the Nexus 5 which has been a blessing up until now when it decided to shut off the screen and freeze or turn off without a way to power up again (there's no way to tell which).
I've tried everything I can think of to reboot the device including:
•Holding the power button
•Holding power button+volume up
•Holding power button+volume down
•Holding power button and both volume keys
•The above while connected to the charger
•Letting it charge for a\an minute\hour\multiple hours then repeating the above steps
Here's all the info I have:
•The phone was in a normal state being used as it usually would before the incident
•The battery level was around 80%
•Right before the incident the speaker used to play back music, video, and apparently allows you to use your voice to input text stopped working.
•Right after the incident the temperature began to rise exponentially (as if the phone was still on but frozen) before cooling and heating again randomly.
Again anyone's input or advice\help will be greatly appreciated! Thank you for your time and of course any suggestions will do so don't be shy.

Yikes. I'd RMA. Sounds like you got a faulty one.
Sent from my Nexus 5 using xda app-developers app

Unfortunately because Google requires another $350 authorization hold before they send a replacement I can not RMA at the moment.

If no button combination turns it on for you, even with the charger...
I think your next best bets are to:
A: Let it DIE overnight.
or B: Let it charge overnight and come to it when you wake up.
If that doesn't work, maybe give Google a good ol' ring?
Those last few words before death on your phone are kind of troubling sounding. Maybe something when haywire?
Was it a Stock Nexus 5?

All of the button combinations did manage to finally turn off the device. So no letting the battery die anytime soon.
It was a stock rooted android 4.4 KitKat.

[HELP] Stock 5.0.1 phone power up issue

Hello,
I flashed the latest LRX22C image on my nexus 5 today.Had flashed it clean,wiping data,cache and system etc except the Internal Storage.Then I flashed the SUPERSU 2.37 ZIP .Everything was fine for about 4 hours.Then suddenly when I pressed the power button to turn the screen off,it was not turning off and the "Switch off" mode was popping up instead .Then, when I got a call,it switched off.The phone won't turn on again.It starts,the Google Boot Splash appears and the bootanimation starts for like 2 seconds and it switches off.Same thing for bootloader mode.
Please Help me!
EDIT: Now its turning on by itself and switches off in 2 seconds!

Sounds like a bad power switch to me, but of course that is just my opinion. :good:

sounds like a mech issue.

I have the same problem on mine now... Basically my phone powered down around 45%. Battery. At the time i thought it was dead... But it wasnt. When i would plug into external power, either usb or through wireless charging it would power cycle continuously at the android splash screen.... (1 to 2 second intervals - even if i booted into fastboot) Interestingly it would never go to the battery charging mode. But automatically boot on charge... It did this for about 6 hours then i gave up and left it unplugged for a day. I plugged it back in and it started power cycling again, however this time on its third boot it came back to life . thats when i discovered i still had 40% battery... I dont know what exactly made it boot but it did. Oddly also on boot, it started optimising apps and finishing install again. I checked the md5 before I installed the update so no issue there. Since it powered up i have powered the phone off using the power button long push and let the phone power down. After doing this when i plug the phone in to usb charge it goes to the charge screen. No issue. That said, if i try to power up while tethered and charging it will not allow it. It just stays at the charge screen. As soon as i unplug the usb the power button allows the phone to power up and work... When booted up it charges as normal when plugged in. Im convinced there is an issue with the power management drivers or drivers for the button controls. My phone worked fine until the 5.0.1 update was installed. On my nexus 5. Anyone else or just us two? Ive had a hard time finding people posting on this issue.

[Q] xperia z3 not respondig

hello,
I had left my phone to charge at night, then this morning it was not responding. Power button was not waking up the phone. Then i forced to reset by power and volume buttons. Vibrated 3 times and completely shut off. Now it is not opening.
I already tried, reset button in sim cards slot. It is not working also. Please help me.

Did you try connecting it to PC Suite or FLashtool? Check that once and also try charging another hour and then force reset the phone. Also I think there is a reset button somewhere under the sim card slot. Try that one too.

Hold volume up and press power. Wait for beep three times. Give it a few seconds and then press power alone, should boot.

Thanks guys, i tried both but still i have sudden death. reset button and power+volume buttons not working. Also flashtool could'nt find my device.

Thats not good, any led when plugged in?

I had a similar instance after flashing unofficial cm12. Phone was cooling down from taking a run through an obvious cpu bug that really killed my battery. I shut it off to cool down with 20 precent still left in the battery. And the phone started to act this way when I went to power it on. No led power indicator or anything even with usb connected. My computer did respond to the usb being connected as if a device was there though. I waited about 10 minutes with the phone in front of some cool air and then did the volume up power button reset which worked then. Still quite a scary incident.

Nexus 5 Android Power UP

Hi,
First I hope I'm posting this in the right place - to get assistance/direction that will help my situation. If not my apologies - please send me to the right place.
I have a Nexus 5, Android 5.0.1, Rooted.
- My device was charging then suddenly went into boot cycle - showing the Google logo then powering off and repeating the same. Trying to get into recovery mode was impossible - would power cycle out of there too.
- I have tried doing the multiple fast press, and sticky button clean solution (actually taking the back plate off etc.) posted out on the net but that has not resolved my issue.
- Left my phone to charge overnight. The problem still persists. More accurately. Turning it on without it plugged in to the charger does nothing.
All the following is the behavior when its plugged into the charger:
- Without pressing any button just shows a full battery charge icon for about 8 sec then the screen turns black for two seconds and that keeps on repeating. If I press the power button it shows the Google logo for a 1.5 seconds and shuts of, going back to the battery charge icon flashing cycle.
- Now if I press the power and volume down button It takes me to the fast boot mode screen where can cycle through the menu's <Start, Restart Bootloader, Recovery mode, power off>. None of the options work. No matter which I chose the phone shuts of and goes back to the full battery icon cycle.
- I was thinking a battery issue but, when in recovery mode the phone will not turn off. I can use the volume buttons to go through the menu as pointed above but using the power button just takes me back to the battery icon cycle. Now I'm not sure, battery, power button or software. What could it be?
I am thinking, try a new battery or, damn buy a new phone (my phone has outlived its warranty). If there are any ideas on fixing this I'll appreciate your opinions. If i have to get a new phone is there any hope of salvaging data. I have a 4 month backup on my computer, but my latest is stored on my phone.
Thanks.

If you run into this issue and none of the solutions in my original post apply, read on in case my final solution helps you out (you might not even have to get paid help if you know how to work on the fault I was experiencing). If not - nothing more for you to gain if you read on.
As it stands:
I took my device to a reputable cell repair shop. After describing to them the symptoms of my device the out ruled the stuck power button issue and tentatively diagnosed it as a firmware bug or nand memory corruption issue which would require a nand mem flash which they had the tools to do. I went for it.
When I went to pickup the device. They reported that the device was functional and they did not even have to do the flush. My data is safe. Issue was a loose battery contact which they detected and fixed. It's been 8 hours and all looks good. These guys were going to charge me a $80 bill to do the flash if the recovery was successful, but I had to leave a $56 deposit after tax for them to begin the work and pay the balance if the procedure was successful. When closing the deal they just gave me the device and said since they did not have to do what they anticipated, the deposit I left them was satisfactory.
I have my device back and working (at least for now) and have the chance to make external backups incase the issue reoccurs. I'm happy. Cheers.

Dead GFlex2: get LG logo but no startup (or Recovery)

My LG G Flex 2 H950 was working fine, running google maps and playing music, plugged in to the car charger. Within minutes of leaving the car the phone was dead - I could not power it on. I can usually get it to show the LG logo by trying to start in Recovery Mode (holding the power and volume-down buttons for several seconds) but then the logo just disappears after a few seconds and the phone does not power on. But sometimes when I try this the red LED blinks on the phone screen and the logo may or may not appear. Sometimes (50%) when I plug the phone in to my Windows 10 desktop, the computer plays a tone to indicate a new device has been connected, but no icon appears in the list of hard drives or devices.
I think the battery is charging normally - when I connect the phone to a USB volt meter it usually (but not always) shows a normal amount of amperage flowing, and just now when I tried to start the phone it showed the battery charge icon on the phone screen (it doesn't usually do this) and showed 100% charge.
Is there anything else I can try, even if just to get the phone running long enough to backup my text messages etc?
Is there any way to test what's actually wrong? I'd hate to spend money on a new battery or charging port etc for a slim chance to temporarily fix a phone that seems like it's dying.
Thanks for any advice or suggestions...

Hey, i've got the same problem since today. i was watching youtube videos when the phone suddenly stopped working. did you already find the problem?
Sorry for my bad englisch ( Dutch)

No - not solved, phone still dead. Still would love to hear any advice...

I used to have the exact same problem as you - bootloops at the LG logo, no recovery etc. After some reading it seemed that the battery was the root of the problem, and after replacing the battery my phone was back to life - no issues ever since. I recommend you check if the battery is the issue by connecting it to a normal charger (i.e. not charging from a PC) and powering it on, by holding the power button at the battery charging screen. If it powers on normally then it's most likely a battery issue, which can be easily fixed. Cheers!
