Nexus 5 having random reboots every 8 mins or so - Nexus 5 Q&A, Help & Troubleshooting

So my nexus 5 had the power button problem so i opened up the phone and cleaned it with alcohol and blew air, it would work but then start having random reboots every often. i have tried using a custom recovery, flashing a custom os, rooting the device, remapping the power button to volume buttons(which just makes it reboot even more) , tried cleaning the power and volume button 3 times again but still having random reboots.
please help me I've heard that this may be a power button problem and that i might need to replace it but isnt there any other way or is it some other problem?
also the phone heats up over 65 degrees due to constant reboots
currently on stock 6.0.1 .

Frequent reboots and power offs but not while charging, generally Wierd

Hi,
I have a Z520e running MaximusHD for 4-5 months now, but last two weeks were quite difficult to me. All started with my phone random rebooting and sometimes it was just turned off. Later issue started to be more and more annoying reaching reboot after 3-4 minutes after screen off.
The thing is it never reboots while I'm using the phone (only when screen is off) and it never reboots when it's connected to a charger.
Since I was using ElementalX kernel I reflashed to stock but it didn't help I even tried to change Radio to 1.15 (originally 1.20). Since I thought it was ROM related I reflashed rom and firmware but it didn't help.
`
Now sometimes I have problem powering the phone I try pressing vol- + power, vol+ + power or both vol with power with charger connected or disconnected end eventually I manage to power it on but it's difficult to say which combination actually worked. Sometimes I have problems to get into recovery because phone just reboots. And sometimes charging led isn't lit even the phone is connected (of course when it won't power up).
I would thought it's a hardware problem and I even started to look for a new MoBo but one day after flashing 1.20 radio and stock kernel It was all ok, I run for around 4 days with no reboot so I thought now is a moment to try ElmentalX - it run for around 1 day with no problem, but after that everything came back.
I tried flashing also bulletproof and Bricked kernels - but I think I did something wrong cause it won't power up (black screen instead of boot logo with button leds lit).
I've also tried reflashing recovery and flashing kernel via fastboot - no help.
But if I manage to flash kernel, or just clearing dalvik - phone will power up, set everything again and it will work as long as I will use it - because when I turn off the screen it's hard to predict anything. Now most of the time I keep charging phone so it is working.
I even found a thing of HOX about reseting charging circuit by pressing both vol buttons and power for 2 min. Once I by doing that I managed to power on, when I had a problem doing that - but it didn't solve anything.
And in last_kmsg I found restart reason 0x776655AA which is kernel panic - but I didn't find anything helpful
Any ideas what can I try instead of changing mobo or trying stock rom - because I really want to stick to maximus and I was running several months without a problem ;/
Try flashing awesome kernel cleaning tool from [URL="http://d-h.st/HDi" ]here[/URL] and flash a kernel afterwards.
Sent from my One S
It didn't help. I'm starting again to think maybe it's voltage control or something but hardware related. Curious is that I've managed to run smoothly for 3-4 days, but I'll start to look for another mobo.

Last chance will be going back to stock, but I really hate do that ;/

[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.

Random reboots to Optimizing App screen

My phone is on 5.1.1 custom Rom. I am having issues with random reboots. I did fresh install after flashing factory image. Phone reboots randomly and stuck on boot logo. After several attempt to restart phone, it goes into Android optimizing app screen and starts optimizing few apps. it boots normally after completion. how do i solve this issue.
I am really pissed with this issue. I havent installed any other kernel but phone continues to reboot to "Optimizing apps 1 of 166" screen.
Please help.
It looks like phone get bricked. I tried to wipe data, system, cache to install Rom but phone gets restart. I am able to reboot to bootloader but phone gets restart again. How do i install factory rom with this issue.
Problem of power button
This is not a software problem as this optimization of apps is due to the failure or shot of power button have you ever noticed this happens only when. You use power button ..
These are solutions for you
If your phone is under warranty carry it to the service center.
If not it is so expensive that the authorized service request you to change whole mother board.
Better find any local service center to replace power button..
Or use apps like gravity screen which helps you to use the phone without the need of power button but concern is it consume more battery..
Or
Rapidly press your phone power button until the phone is completely on till home screen is visible this is only a temporary solution
As I am junior member I can't share any link of the video about nexus 5 power button failure
Just search in YouTube for nexus 5 power button then you can a video of 2min 6sec just do as same may help you

Nexus 5 rebooting continuously and don't start without power source

Hello everyone,
I was flashing MIUI official on my nexus 5, and I was in bootloader, and I was just simply press power button then devices just turned off and
wont start again. after turned off, device dont start using power button, then I connect power source, device just started and rebooting again and again, without power source device dont start, and when it starts on power source, device just rebooting continuously,
Service center said you need to change mother board.
It is necessary to change board or this is just a problem of power button stuck inside
Any sujection?
I suggest removing the motherboard. Then, quickly press and release the power button several times in a row using more pressure than normal. Not too much pressure as you don't want to cause any further damage.
If that doesn't solve the problem, it could be a battery issue.

I have not flashed my phone but have kept it up to date. I have version 6.01 build MMB29Q. I have had the issue during the last two weeks with it restarting but then just going off again. I have a separate Nexus 5 I user for parts for these situations. I replaced the motherboard got it up and running, everything seemed fine but then the power would just go off for no reason. The only way I could get it to restart was by holding the volume down for 10 seconds and then selecting the power button. The difference with this motherboard is that it will at least start up. I did change the battery as well and that did not make any difference. At this point I am thinking about flashing with a different OS to see if that fixes it. I unfortunately do not have a fix but I am at least at a point where I know how to keep it functional. Any further fix suggestions would be appreciated. I think my next step will be to flash it with a different OS to see if this issue persists.

I am confused, its battery issue or power button issue, I will try to repair my phone in shop not in service center
Chances are that you have the same problem I had with the power button.
My N5 had this behavior and was about to be replaced when I found something that worked. Try this: press and hold the power button several times with more pressure than usual. If no luck, smack it a few times (no kidding) in a table - I suggest you to do it with a cover. The main problem is with the switch soldered on the motherboard and the above steps is to 'unlock / release' the internal parts of this switch - the main culprit.
Several people had this issue and the spank showed to be useful: LINK
My N5 is working just fine, almost two weeks now. Good luck!

Nexus 5 - Volume up button apparently stuck

Hey there,
my Nexus 5 (Android 6.0.1, Security Patch-Level: 2017/10/05) appears to be suffering from a stuck volume up button.
I have had a similar problem regarding the power button, which sent my Nexus 5 into endless bootloops. I was able to solve the power button problem by hitting the phone against the palm of my hand repeatedly.
In the case of the power button there doesn't seem to be an easy fix. Smacking it against my hand did not do the trick. The problem appears to occur randomly with the ringtone and/or media volume jumping to full blast from one second to the next.
In some cases I can lower the volume and it stays that way. Other times I can press and hold the volume down button and upon release it jumps right back to full volume.
I will try the following steps:
1) Diassemble the phone and clean the buttons
2) Flash the stock ROM to make sure, that it is not a software issue
I was wondering if you had any ideas/ additional steps, which I can take to fix the problem?
Thanks in advance!
Ron
Just got mine back from repair, got stuck in bootloop, only new microswitch helped.
I also suspected the ROM, but now it's fine again.
So I do recommend to change the microswitch, it's cheap...
Just be careful (or mention it to whoever will do it), it's being held in place not just with the solder but also somehow glued to the PCB. Don't force it too much. Take your time.
