Nexus Won't Boot Up - Nexus 5 Q&A, Help & Troubleshooting

Help! My nexus 5 won't turn on after only having it for about a year now.. It's not a boot loop!
Here's what's happening:
-My phone boots up to the google sign and then the 4 moving color dots... It never gets past this screen.
-If the phone is plugged in, the phone will continue this looping process all night.
-If the phone is not plugged in, it will only occur twice when the power button is pushed.
-If I attempt to access the bootloader, I only see the screen for a split second until the google screen reappears and the loop begins all over again.
-I can get past the 4 dot screen by repeatedly hitting the power button on an interval of roughly once per second.
-If I do this, the next screen to appear is the "Android is upgrading.." "optimizing 0 out of 130 apps."
-This screen will not progress through all 130 apps however, unless i keep pressing the power button at the interval of roughly once per second.
I used to successfully make it through the start up process this way and be okay for the day, but now my phone will shut off once the home screen is reached. It seems to me that the power button was a bit too sensitive, but I took the phone apart and it is working fine. I did drop my, which cracked the screen, about a month ago. About a week ago is when the problems began to occur. The insides look good though, just the screen which is cracked. Any ideas would be greatly appreciated!
I'm trying to hold out for the Nexus 5 (2015)!

Dead power button it is.
In Indian LG service centers they replace out of warranty handset's power button for 330inr roughly 5usd.
I had the exact problem and thought is discarding the phone, but the repair fixed it.

Thanks, I'll look into this. Maybe try to do it myself real quick.

It's not easy to replace yourself, ad the button is soldered to the board. Best give it to a pro lab.

Bang it on a hard surface like a table. That is a temporary fix when my power button starts to act up. You can try hitting it on the palm of your hand, but that doesn't really jar it enough.

broken fuze. powers on as soon as battery is popped in

So I've had my fuze a little over a year now, no major issues. Used mostly energyroms, but about December time I switched back to a simple non-bloated stock rom for the stability.
Anyway today at work I was texting, and I press the power button to put the phone in standby. And the screen remains on and usable. I tried again and it would not go into standby (power button physically feels normal, it does not feel loose or abnormal.) So i let it sit for a few minutes, then i look at it and a message poped up asking if i wanted to turn the phone off (like as if i was holding the power button)so i press no, then it comes up again a few seconds later and aagain and again. So I soft reset the phone.
The phone resets but takes a LOT longer at the att/htc splashscreen, then it hangs at the htc screen and does not make it to the wimo screen, but instead an error screen saying:
"The device is unable to boot because you have either turned off the device incorrectly or tried to install an applicationa from an untrusted source, press SEND to reset your device or press any other button to cancel..."
I think it went through the hard reset this time because when it restarted it asked to calibrate the screen and install stuff. it resets again sometime after that, still takes forever at the splash screen and comes back up to the error, only this time no matter what button i press it wont go away and boot into wimo. It seems like none of my buttons work (they wont light up now) when i slide out the keyboard, it is not lit up like normally.
And heres the kicker, my only way to turn on/off the phone is to take out/put in the battery. As soon as I pop the battery back in the fuze turns on. Is my phone toast? Ive tried to hard reset and the phone does not reach the bootloader, it goes straight to the splash screen. Same with trying to reflash it from my comp, raphealwrapper cannot find my phone.
I've only recently encountered the exact same problem on my Touch Pro, but stock ROM and everything. As far as I can tell, our power buttons are busted and probably need to be serviced. One of the contacts must be stuck in the 'on' position somewhere inside :\ As a temporary fix, I've been using AEButton Plus and remapped double tap end call key to turn the screen off, and removing the stylus to turn it on.

Moto G Wont Turn On

I have upgraded my moto g from 4.3.3 to 4.4.4 and it wont turn on all it gives me is a white light flashing.
I relay need some help.
Thank You
Did the phone run out of battery power in the middle of installing the update?
Have you managed to resolve the problem?
I have had the white flashing problem before with Moto G, although it was nothing to do with the upgrade.
1) Ensure the phone is turned off
2) Hold the power button down and the volume button down at the same time. ( As in lowering down volume end not the increase volume end)
3) Hold both buttons down for over 36 seconds and you should see the screen turning itself on.
I know it's over 36 seconds as both Moto G phones did exactly the same thing to me and it was in regards to the battery.
This is the weird bit okay.... It may not work for at first and may not work the second time and may not work the third time.
Give the phone a break for a few mins...
Try number 1 - 3 again and this time - Don't hold it on for over 30 seconds...
4) Hold the power button down and volume button down for over 2 minutes - and MAKE SURE THEY ARE KEPT DOWN and don't let go at any point. You may on the rare occassion see the white light flash twice and then within the two minutes the power will come on!
Now if it doesnt come on don't worry at this point. - You can try number 4 again if you want... Sometimes it works and sometimes it doesn't.
Ensure the phone is switched off and leave it for a while.... If you sure you have enough battery power - don't recharge it unless you have to.
Give it a couple of hours of leaving the phone alone....
Press the power button down and the volume down again... Try it and you should be taken into the bootloader mode and just press reboot and the phone will reboot properly... It may take a few minutes to reboot longer than usual. But when the phone loads up all is back to normal again...
Do this occassionally as the longest period I had from it being unable to turn it on was 8 hours.
I know this may not make sense at all - But when I bought two Moto G 2014 4 G version when it first came out, and the battery was problematic and glitching I went through - 5 Moto G's all in all before I had a phone that stopped giving me these problems. That's taking it back and exchanging it and all that. Normally I would have given up, but Motorola went above and beyond during this battery problem and I couldn't fault them in regards to the phone being exchanged and their follow up emails in making sure all was okay.
Try the - If it doesn't work - You have two options - Take the phone back to where you bought it from and get them to sort it out. If no joy, contact Motorola and you will find them really helpful in sorting your phone out or even exchanging it for a new one.
Hope this helps....

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.

I broke my screen- how can I power down?

Like it says, I broke the screen (crushed in the frameworks of my recliner) but it is still powered up. I press the power button, and I can feel it twitch, but it never shuts off. Is there any multi-button way to power down? Not only can I not see my screen, but I think the touch is bad as well. I could not get it to answer the call when I called if from a land line.
I've pulled the SIM, so that all my calls go to vmail.
Good news- I got it to shut off. The only way to tell is to connect it to my PC and see if it enumerates in the device manager. It does not show up under adb or fastboot, so I must have deleted all those keys with the last OOS update.
If I just hold down the power button for about 30 seconds, it eventually gives one big twitch indicating that it is shutting down. After that, it does not enum in device manager any more, although the charging LED is still operational.
More good news- I have a new 7 Pro on the way as a replacement. Looking forward to that.

General Found A New Bug

Hello people,
This is probably the most annoying bug I have seen in my Pixel.
I wanted to take a screenshot when playing a video in Full HD on YouTube. It started, I took the screenshot right when I needed by pressing the Power button and Volume Down button simultaneously. It was in full screen mode. And then disaster happened. The screen just went completely freeze. It was stuck at the screen where color palette choosing options etc. are given as soon as you take a scrnshot.
I touched the onscreen buttons nothing happened. I held Power button to activate Google Assistant. Although the assistant responded to me I did not see nothing. I set my display to turn off after 30 secs. Shortly before 30 secs it dims. The same behavior was happening except for the screen never went off.
I had to search [using other device] and come to learn that pressing the Power button about 30 secs will turn the phone off/restart. Finally, the phone came back to normalcy.
No melodrama over here. Such freezing may occur. It is just that this is my 2nd Pixel Phone [the first being the 3A] and ever since I've started using a Pixel I never ever had to do such operation.
Has it occurred to anyone?
My Pixel is exactly 5 months old. I enjoy dailying it.
