Device won't start - Nexus 5 Q&A, Help & Troubleshooting

Hi everyone,
I read a lot this forum and always found what I was looking for to help me but today my searches didn't answer my questions.
So first of all, thanx all for your time and help.
My totally stock Nexus 5 D821 stopped to work yesterday.
It worked fine and went to sleep. When I pushed the power button to wake it up, nothing happenned. I tried all the "long press" and "press power + vol down" ... still no life in the phone. Not even a little "buzzzz" from the viber.
I thought the battery was dead (even I was sure the charge was OK) so I switch my battery with my son's Nexus 5. Didn't work.
Put my battery in his phone, the battery charges correctly and was OK.
So it's not the battery.
Switched all covers to make sure it's not them. Nothing changed.
Switched our motherboards, no change.
The power button ? May be but how can I test it ?
If you have any idea, let me know.
Thanx for reading.

[Q] Phone turns off

Hey guys,
I'd like to apologize, if this was already solved somewhere on this forum, but I couldn't find anything, so let me tell the problem.
I've had my Sensation for about 4 months and it is really great, but now it has really weird problems.
The first one is that when I press home button, it takes a screen, I found out that the problem is the power button, which is really sensible, but, here's another problem.
When I charge battery, everythings OK, my phone doesn't turn off, but when phone runs on battery only and I do not anything (screen is locked), it automatically shuts down and I need to remove the battery to turn it on again.
I use HyperSensation, so my phone is rooted. Could anyone help? Thanks.

unable to turn on my One XL

Hi,
i have very strange issue which i noticed right now. It seems that i can not turn on my mobile/screen. I have to say that mobile is bought less then month ago and no modifications are made like rooting or something like that. Today it worked without any problems and when i got home i left it on my desk but two hours later i wanted to check for my e mail but screen/mobile is not turning on. I checked on/off button and it's not jammed. What else can i do considering that i can not remove the battery

Charge the phone. Could be dead. Are you SURE nothing has been modified? Also, hold down the power button until you see the capacitive buttons flashing, and don't let go until they stop flashing and the phone reboots.
Battery probably died. This phone is known to lose power abruptly. It's happened to nearly everyone at some point--it will appear to have some charge left and then suddenly drop to 0%.
Just leave it plugged in for a while and see if it revives.
nothing helped from what you mentioned but it works now. When i plugged in the charger there was no sign of charging. When i pressed and hold power button also nothing happened. Then i tried to hold volume down and power button but also no reaction from the phone and then i pressed the mobile bit harder around display to check that maybe there is no loose wire and at this point mobile turned on by itself (boot screen) and after booting there was crash report. I have HTC phones for years now and such problem never occurred to me before but phone works for now :good:
thank you
Hopefully it isn't a defect, my one x has never went off on me at a random battery percentage, except for some ROMs he he
As mentioned, some people have had instances of randomly losing charge, or phone not seeming to take a charge after running the battery down. Leaving the phone on the wall charger (not USB, which takes much longer) for several hours (overnight) and then trying to power on seems to solve the problem. One guy here could not get any response (even after charging for hours) except by holding the power button while the phone was on the charger.
The issue seems completely random. So unless it persists, probably nothing to worry about.

HTC Sensation Power Button (On/OFF) doesn't work.

Hi everyone. Today i was chargin my phone at PC using a no-name usb cable. I've noticed while it was charging that the screen kept turning itself on and off. When i finaly took the phone, the screen was unlocked and when I tried to press the home button it did nothing but taking screenshots (like the power button was stuck). The power button was not wroking either.. After I took out the battery and restarted the phone, the power button didn't work at all. Tried to clean it off using this method but it did not work. Tried to clean the power off button using a method i've seen on google (can't post the link since i'm a new user) but its still not working
I'm desperate, please help
Are you sure, that the problem is only the power button? I have sometimes problems with this phone too. Sometimes you can't turn it on.
Try taking the battery out for at least one hour - then try to start it. I had always success with this.

The batter has proven me to be fcked in the last week, had lots lots lots of random turn-offs and restarts. But for more than 5 hours the power off button didn't work.
I'll let my batter out through the night.
Thanks for reply.
PS: I'm running ARHD 7.3.

The restarts can also result from a loose battery. Try putting a folded piece of paper between the battery and the upper casing of the phone, so the battery is pushed against the pins. This is a well-known issue. It helped me a lot. Before I had also lots of reboots.
Yep, did that in the last 1,5 year and the random reboots stopped. But as i've said, now it happens even tho' i have a paper that keeps the battery steady.
Lol just took the phone to see if the power button works and currently i'm talking screenshos pressing the home button .

How did you turn on your phone if the power button doesn't work?

I take the battery out, put it back in and after a few seconds the phone turns on.

Well, this isn't normal. Is your power button constantly pressed?
Try the following: Hold the volume down-button while inserting your battery until the phone boots up.
Does it boot into the boot manager?
Just woke up, plugged my battery in and the power button worked almost normally. Could've pressed it 5 minutes and after that and a restart it didn't work anymore.
This means I should buy a new battery and everything is fixed? Are the Anker batteries worth it ? Or do you recommend me a HTC EVO 3D battery ?

You can use the battery from the Sensation XE, which has 1.700mAh instead of 1.520 (or 1.560). At the HTC-Store they are about 50 € here in germany.
Always buy original batteries! Not the cheap ones from eBay. They usually don't have a temperature sensor, so the phone can't shut down, when it gets too hot while charging. This can be very dangerous.
I haven't got any experience with Anker-Batteries - sorry.
Pressed the volume down button and it got me into the boot menu (just like the power button is kept pressed).
Do you think that if I change my batter it will fix my problems ? Also noticed that my battery is altered, aka its not flat but swollen.

If it is swollen, it is definitively broken. Mine had the same symptoms...
I'm pretty sure, the powerbutton-problem isn't related. Does the button feel normal, if you push it? Or is there no "click"?
Maybe you can repair it with a needle by lifting the foil a tiny bit.
i dont think you need a new battery, same problem occurred with my phone, done some DIY fix and written that in a post for fellows like you in search of help.
here is the link to it:

A new battery has fixed it.
No problems with the phones until now. It works perfectly

Unbelievable!!! Thanks for the link above - it worked for me, the power button is fixed...

Xperia Z3 Sleep of death / Won't respond to anything

This should help anyone with a Z3 or Z3 compact where their phone doesn't turn on or do ANYTHING.
In my experience I was using my 2 week old Z3, no problems, until one day I locked the screen using the power button and it wouldn't turn back on.
I tried everything, soft reset, hard reset, yellow button next to sim card tray, plugging it into my computer etc etc. Still nothing.
I knew the phone was working because it started to get quite hot towards the top of the phone.
Eventually came across a fix that worked for me and hopefully will for you, so don't think you've got a shiny new ornament just yet.
I don't know what is required and what isn't but this is what worked for me:
1. Hold the volume down button for 30 seconds
2. Keep it held and plug your phone into a power source (wall or computer) using the USB cable. No response?
3. Let go of the volume down button. Now press the volume down button and power button together for 5 seconds. Still no response?
4. Press the volume up button and power button together for 10 seconds. This should cause your device to vibrate 3 times and then show the battery charging screen.
5. Turn the device on using the power button as normal.
Alas!
I was ready to send mine off to Sony's awfully long repair service which last time took nearly 8 weeks (I could've personally driven to Japan/China and back from the UK)
Hope this works for someone!
I think the last step is all that's required. Holding the volume up button & power button for a few seconds (5? 10?) will cause it to vibrate 3 times and reset. It gets you out of pretty much anywhere; learned that from messing with my Z1C's bootloader.
Having the same problem
I'm having the same problem, my Z3 compact is nearly 4 weeks old.
during 5 in the morning, my battery is at 80%, then I lock the screen and went to sleep.
then I woke up around 4pm and my phone is dead as ****, doesn't respond to anything
I do. I've tried what you've said in this post and nothing happens.
I have few APPS in my phone and I never tried exposing my phone into water. can somebody please
help me

One pretty important feature you left out here, which is as close as you can get as a battery pull, open the microsd slot, and inside is a little yellow button, push this in will 9 times out of 10 power cycle your phone.
Same problem

I am having the same problem. I just bought the device through Amazon DE and i am thinking in returning it. Any way to solve this ?
I have noticed that in my case, at least, this is always happening when the battery percentage is getting close to 50% (half of the battery is consumed). I have KitKat 4.4.4 and i expect this problem to be solved with the new Android 5.0 Lollipop upgrade.
Sleep of death companion... other issues?
Hello all,
Xperia Z3 (Tmo D6616) since January. Super happy with the phone, especially being able to run long distance without worrying about sweat damage, listening to music in the shower, and other shenanigans otherwise impossible before. Anyways, yesterday morning i was showering, phone was alright. After shower dried the phone with a towel and put it on a shelf in the bathroom. Forgot about the phone for thirty minutes, came back and noticed that the camera had fog condensation inside the lens. Ohhhh! crap, so I open the ports and put the phone near a fan. Also, phone wont turn on... So my first thought is water damage. So I packed the phone in dry rice for a few hours. Take sim and SD card out. Next i decide to power cycle the phone with the yellow button on the sim port. Phone buzzes three times. But after that... nothing. Phone has been stored in rice since. When i plug it i get rapid red led blinking. I called Tmo and dude tells me that he has the same phone, and that it souds like deep sleep, not water damage, due to led and buzzing. Problem is i can't replicate buzzing and no combination of the above seems to work. At a loss. Any of you know what the red led blinking means while the usb charger plugged?
PS: condensation gone from phone, or so it seems.
Same problem
Hi all,
After 4 weeks my new Z3 would randomly shutdown and I would turn it back on, until of course it refused to switch back on.
I have attempted a hard reset using all 3 combinations of the power and volume buttons. The only response was 3 vibrations from holding all 3 buttons whilst plugged into a charger. The red light would flash intermittently whilst on charge, and constantly when either buttons are held down.
When plugged into a PC, the USB connection would repeatedly connect and disconnect.
Is there any hope? I need to recover photos from my mothers funeral.

FYI, currently in RMA process through Tmo... gonna get a refurb... not the happiest camper with Sony's approach, however, this begs the question: Given the spate of issues with Z3's maybe a refurb would not be such a bad idea, especially if it addresses the issues that are most common... Anyone received a Z3 refurbished? Would you mind sharing your experience?

Doesn't help you, but as a side note, I had mine replaced twice using Jump and both times I received a brand new phone sealed in the box. BTW, last one has Dec 14 build date and the assembly is much better than earlier ones I had.
super thanks!!!

hello, at last i found the answer,! tried all the suggested actions i searched on the blogs, but this one really worked for my xperia z3c and after that it updated to lollipop, i hope it would not shut down randomly again, i'll wait for maybe 2 months before i actually make it my main phone again, but at least it's back now and i really miss my xperia z3c, it's really the best for me thanks to you!!! God bless!
Sometimes (once/day), when i woke up my Z3C from sleep, the touch screen is frozen and the only way is to reboot it with power and volume buttons.
How can i debug this behavior ? I found nothing about that issue...
Thanks for this post!
I've managed to get to the point of three vibrations, but then it just burns the leds in three colors, and then vibrates 3 times again and so on.
I've also managed to get to a point where the led stays constant blue (by playing with the volume up/down).
But now what?
Worked for me
:good::good:
the 4th step worked for me, thank you
4. Press the volume up button and power button together for 10 seconds. This should cause your device to vibrate 3 times and then show the battery charging screen.
Xperia Z3 keeps restarting when trying to charge
Hi all, I don't know if someone did encounter same problem as I. Yesterday my Z3 was 100% charged. Overnight the phone started to restart and battery % went nearly dead showing around 2% left and the red led light starting blinking as well. I tried to plug on charge to a wall source and now it keeps restarting and the "Sony" logo only would appear and it keeps to restart again.
Saw some solutions among which I have tried press holding the volume up button along the power button so as it should vibrate 3 time but in vain. The phone ain't charging anymore and it keeps restarting either plugged with my pc or wall.
Please can anyone help on this one?
Cheers

Have you tried connecting to a charger?
I rebooted mine the other day and it wouldn't come back on, had about 60% battery as well. Connected to charger and that brought it back to life. Though usually when the battery has drained and it needs to be connected to low power USB connection to trickle charge and get charge back in the battery. Had this happen with other devices, so not OPO specific.
Same problem
I have same problem. My oneplus is not starting anymore. My battery was 80%
Now I can't start my mobile
Thanks in advance!
Oneplus Not Starting
HI,
I used the power cycle option (Power cycle the One by holding the Power button for 20 seconds 5 times.) and it worked for me.
