Nexus 5 problems turning on - Nexus 5 Q&A, Help & Troubleshooting

i have a 32gb white nexus 5, fully charged. stock OS, rooted with TWRP recovery. using Faux123 kernel.
what's weird is that i am unable to turn on the device:
- if i power off the phone and attempt to power it on
- reboot the phone (it will shut off like it's rebooting, but won't turn back on)
pressing and releasing the power button, holding the power button for X amount of time and releasing, etc will not turn on the phone.
in order to turn it back on i have to use vol down + power...even then i have to hold it, release, hold, release, etc and by random chance the phone will boot into bootloader.
the power button doesn't seem to be the issue because it works fine turning the display on/off while the phone is on.
i have not figured any pattern or why this is happening.
has anyone else experienced similar issues?

Your best bet is to go back to stock. Stay stock for a bit and have a baseline to know how your phone is. Then after you start customizing it with 3rd party kernels, ect, you'll know if it's the phone or mods you did.

[Q] Can't get my tablet to boot into Recovery/Download mode

Hello,
Hopefully I'm in the right place for posting something that seems to be this simple. The start of my problem is that the tablet will not stay off. When I try to shut it down, it shuts down normally, but then it starts to display the battery icons like it is plugged in and charging, but it is not connected to power. I can leave it in sleep mode and the charging thing will not happen, but turning it off displays the power charging screen and it further drains the battery. I figured something is screwy with the system so I would try to reset it to factory defaults. Now I have the other problem...
So I am trying to restore to factory defaults and I know to do this I have to start from off and hold down the up volume and the power button for a few seconds and as soon as the tablet starts to turn on release the power button but not the volume up button, and it should get me into the recovery/download screen. Unfortunately that is not working. I hold down the Volume up button and briefly hold the power button (3 or 4 sec or so) and I see the Samsung Galaxy Tab 2 7.0 startup screen and let go of the power button (still holding the Volume up button). Next I see the spinning blue circle around the Samsung logo and the tablet reboots. I can release the volume up button at any time after that and the results are the same, it just reboots. It's like it isn't seeing the volume button.
I have tried using the volume Down button instead of the volume up button but that too is just like I am not pushing any volume button at all. Once the tablet is on, the volume buttons function normally, so the switches are good.
Since I got this tablet used could someone have loaded something onto it preventing it from being rebooted into recovery/download mode? Maybe some custom firmware or something. I'm at a loss as to where to go next. Since I can't boot into recovery/download mode I can't get into Odin.
Any help is appreciated.

Hi. The tablet isn't rooted, is it? Can you try to boot it into download or recovery with the "quick boot" app from google play?
I don't think it is rooted, but I can't tell for sure since I can't connect to the Google play store. I tried downloading using the web browser, but my battery dies before if finished. I'll try swapping batteries and see what I can figure out. Thanks for the idea.
Rick
No, the device is not rooted. it also is not charging and I had a heck of a time getting it to connect to the play store. I think I need to try and reload the OS, but without being able to get into ODIN, or reboot into recovery, I'm not sure how to proceed. any suggestions?
When the battery thing appears do the power- volume up thing and hold it until the gtab logo appears.
I've tried that, and it just boots up as if I wasn't holding the volume button at all. Once the tab is booted, the volume buttons work as normal. I've even tried putting a different power/Volume/IR unit in (from a working tab with a broken screen) and that didn't make a difference.
I left the tablet all weekend and it just keeps showing that it is charging when not plugged in. By Monday the battery was 100% dead. It won't even charge. If I replace the battery with a battery from a working unit I'b back in the same place where I can't get it to boot to Recovery/download.

[Q] HTC Desire C CyanogenMod10 - Waking up and then going back to sleep.

Hey, I recently had my friend flash the unofficial CyanogenMod10 ROM onto my HTC Desire C (Non-NFC version)
I am encountering an error where about 80% of the time when my phone is asleep, and I press the power button to wake it, it will flash on and then go back to sleep.
If I press the power button as quick as I possibly can it will still happen, however; if I hold it down it will stay on until I let it go, at which point it will definitely go back to sleep; I honestly don't know what's happening.
It sometimes also occurs when I've taken a screenshot; it has a high chance of going to sleep when I take my finger off of the power button, same as when I hold down to view the power menu. (That shows reboot, turn off, airplane mode, etc.) and when let go of the button it usually also shuts off, what's happening, is this a problem with the ROM, or something I may have changed?
Also this issue only started occurring about 2 days after the initial flash, whereas until the point everything was working nice and smoothly.
This issue is really annoying...
P.S: Would I be better off using the newest JellyTime ROM rather than the vanilla CM ROM on my Desire C?
Thanks!

[Q] Odd Galaxy S3 Power Issues

I honesty don't know how to describe my problem so I guess I will just tell you whats happening and what I know about my phone.
My phone:
Unlocked Verizon Galaxy S3 running CM for recovery, and CyanogenMod 10 for the ROM (Updated with Odin from Jelly Bean).
The issue:
1) Whenever I press the power button the phone completely shuts off. It doesn't just go to the lock screen, it turns off.
2) The phone will not always turn back on.
3) 85% of the time when it doesn't turn on, it boots into the first splash screen and turns off.
4) When I try to put the phone into download or recovery mode the first screen will pop up for about two seconds and then the phone will turn off again. The phone will either shut down on the cancel/download screen for download mode or the first splash screen with the blue text at the top for recovery mode.
5) The other 15% of the time it will reach the CyanogenMod screen, freeze, then shut off.
6) When I put it on the charger, the stock charging icon pops up but then the phone stops charging and shuts off. (It will charge correctly some times)
These things don't just happen if I press the power button. I used a custom app to turn the phone off without the power button and the problems still occurred.
Things I've tried:
1) Replacing the battery.
2) Switching chargers.
3) Leaving the phone on the charger for a while.
4) Taking the battery out for extended amounts of time.
5) Just leaving the phone alone for a while.
No, the power button isn't stuck... I don't think it is
I am aware that the motherboard might need replaced. However, most of the cases I read about involved the phone not turning on/charging at all. If I could get the phone into recovery mode I would clear the cache and see if that worked, if not I would just factory reset the phone. If I could get into download mode, I would flash a stock firmware and be done with it.
This is my second android phone and I've never had this problem before. I did my experimenting with my old Motorola Droid so I could make sure I knew what was safe with my S3 but apparently there is something wrong.
I greatly appreciate any and all help and please do help me
[EDIT #1]
I began hitting the power button against a hard surface and 1 out of 7 times it works. Perhaps the button is stuck.
[EDIT #2]
I am now able to press the power button without the phone turning off. I will still make a back up and sync all of my important media and prepare to have to factory reset and flash a new ROM.

[Q] Bootloop when power button sometimes pressed

Hi everyone!
I think my bootloop problem may be a unique one because it only occurs whenever I press the power button (and I've kinda searched other threads and couldn't find a bootloop issue like mine). But before I explain in depth, here are my specs:
Stock 4.4.4 rom
Rooted, with xposed + gb
ElementalX 1.00 kernel
This problem is a randomly occurring one; when my phone is fine and I press the power button, it almost usually goes into a bootloop. It can either stay on the google screen or last all the way up to the x-boot one. Sometimes from the x-boot screen, it'll reboot again. So I realized that if I randomly press the power button a few times (usually trial and error), the problem goes away sometimes and I boot normally again. However, if I hit the power button again for any reason, the bootloop issue relapses.
Also another thing to note is sometimes when my phone is switched on and operating normally and I press the button, it doesn't always reboot immediately. Sometimes it behaves as if the power button is held down and the power menu pops up in the lockscreen... then subsequently it boot loops.
So I'm not sure if this is a hardware issue to do with the button itself (because I very rarely ever drop my phone. Perhaps about 3 times in the past 8-9 months since Dec 2013?) or it's a software issue...which will mean I've to reflash my stock rom.
Anyone with a similar issue please help! It's kinda driving me nuts cos I can't even unlock my phone without triggering a bootloop...:crying:

Might want to send it in for repair. Mine had the same symptoms about a month ago--spontaneously displaying the power menu, boot loops where I'd need to do a hardware reboot (or whatever it's called, vol up + power) and sometimes it won't wake the screen when I press the power button and act as if I turned it off. Tried to reflash recovery and change roms, same banana. Then suddenly it won't go out of bootloop, sometimes gets to the x-boot and sometimes only until the Google logo. Sent it for repair and lo and behold, hardware problem. I think this is really inherent on some older Nexus 5's with the wobbly power button.
I suggest you do a nandroid backup while you have the chance. Never had a chance myself

sigh, i reflashed stock rom and the problem persisted. i can't even stay on the bootloader screen without it rebooting itself all over again. i guess it's an old nexus 5 hardware problem like you said :/ thanks for sharing!

Sounds like the power button is getting stuck, or shorting out.

S7 won't boot, blue LED always on.

Just some minutes ago my S7 froze because of Focus Gallery App. I don't exactly know what it did but the phone did not respond any more.
So pressing the power button did not bring back the phone either. After searching for a bit I found a way to simulate a bettery disconnect by pressing Volume Down + Power Button.
The Phone came back up and displayed the initial boot logo. Also the blue LED is on. But nothing happens from here on. I do not come to the "Samsung" boot animation and the phone simply
does nothing. Retriying Volume Down + Power Button doesn't seem to help too. I tryed all button combinations but nothing brings the phone back.
I also cannot enter the recovery menu. So no chance to reset to default settings.
I am running a stock Android on the phone. Nothing was done by me. No custom ROM, no root, just plain Samsung Android.
Is there sill something I can do?
Edit: I just got into whats seems to be ODIN Mode??? Can I do something from here?
Oddly this happened to me last night although I may have inadvertently done it. But the only way I was able to get my phone functioning again was reflashing the OS to the phone.
How did you manage to get the phone into Odin mode? I'm having the same issue with the phone being totally unresponsive but the blue LED on.
if you can reboot your phone with the VOL Down/Power, when the screen goes black, quickly press and hold VOL Up, Home and Power. it should enter recovery. or hold Vol down, Home and Power to enter the download screen.
I have the S7 Edge (rooted, custom ROM) and it's running fine. My girlfriend's regular S7 is having the same issue though.
When she plugged it in to charge last night, she checked it a few minutes later at which point the phone had (started to) reboot. The blue notification LED was on and the screen had frozen at the 'SA' from the 'SAMSUNG' startup logo. Forced a reboot with down+power, resulting in just the blue LED (no logo this time). Phone was unresponsive (couldn't force a reboot again) so left the battery to drain overnight. The phone is completely dead today even after charging - no LED, no boot, no anything.
I'm not sure if she had the phone scheduled to perform an update overnight and it froze halfway through, but that would be my first guess. So far, no fix.
