Nexus 5 keeps rebooting - Nexus 5 Q&A, Help & Troubleshooting

So I was texting the other night when my phone just rebooted. I see this is a common thing nowadays, but my problem is a little bit more f'ed up. My phone reboots and gets stuck at the Google screen, sometimes it goes past that, to the spinning dots, but just for a second because it reboots again, and again, and again. I tried booting it up with Volume Down + Power button, it get's to the bootloader screen but again, just for a second, because it reboots. I am sure that it is not the battery that is drained because I left the phone charging over night.
Can someone please help me?

Stuck power button issue?

Can you explain please? If this is the case, what should I do?

I never had that issue - I just read about it a few times. Maybe try searching the forums RMA maybe?

HTC Fuze reboot loops

Haven't found any good solid information on my problem so hopefully someone who has some advice can assist and others in my situation won't have trouble finding help.
My HTC Fuze was working fine with a decent charge and I went out and didn't use it again until the next morning. I woke up and it was completely dead. Wouldn't turn on or do anything even after battery pulled. I left the battery out and waited overnight; then charged it up.
It now turned on and got to the home screen (sweet...) except that it immediately rebooted and continued this loop of getting to the home screen and then rebooting.
I'm now in this cycle loop where it just keeps going... so I figured hard reset time, except that holding the bottom volume and enter and hitting the soft reset button, nothing happens at all. So I'm asking now what can I do. I've opened the phone to manually press in the soft reset while trying the hard reset and its still not working.
HTC reboot loops are common and there's tons of information on them, however, I haven't found a solution to this problem. Maybe there is no solution? :-/
I'm using one of the NATF series 5 roms on the device and its been fine for over a year.
Any help is greatly appreciated.
Edit: I was able to hard reset now the damn thing is reboot cycling the "preparing phone for first use" screen. Looks like the phone gets 30 seconds and then just kills itself. This is driving me insane

[Q] Power button is causing phone to reboot nonstop

So, tonight I just turned my screen on and then off real quick to check if I have any messages and set my phone down. Then I look down and see the Samsung logo. I'm a bit confused and notice that the Samsung logo keeps showing for 1-2 seconds going black for 1-2 seconds and then back to the Samsung logo for 1-2 seconds, over and over. I pull the battery and then when I put it back in, the phone starts doing it again before I touch any buttons. Clearly something is causing my power button to be "on" continuously. This seems to be a relatively common problem from doing some searching, but most of the posts I find seem to be full of people responding who fail to understand the problem. People seem to think that this is a boot loop and that it can be fixed by going into download mode. This is clearly not the case, the problem is obviously with the power button since the phone automatically starts up and keeps doing this as soon as the battery is reinserted regardless if no buttons are pushed or all buttons are pushed. Has anyone managed to fix this problem? I'm thinking I'm going to have to take the infuse apart and see if the button is stuck or if there contact occuring somewhere it shouldn't be. Any help would be appreciated.
Yeah, i have this problem. First what i did, i'd hit gently the power button a few times and it seemed to work. But after a few days it got worse, till the point it wouldn't work. I decided to open up the phone myself, and trying to manipulate the small power button. Apparently it worked, but i decided not to use the power button anymore, i wake the phone by touching the volume +/- buttons and i turn it off with a widget i downloaded from the playstore. This problem seems to be on every infuse i'm saving up some money to buy another phone, since i won't be able to sell this one with this problem.

[Q] GS4G keeps reseting every 3 seconds

Hello.
I have searched the forums about my issue, and although there are a lot of threads about phones rebooting, there was none about such exact problem as I am experiencing. I apologize if I missed a thread which tackled this problem.
Symptoms:
1. my galaxy S 4G reboots about every 3 seconds: it only gets to the very first "Samsung Galaxy S 4G T-mobile" logo, and reboot
2. it is possible to access boot menu (volume up+down), but only for a split second, and phone reboots again
3. rebooting starts as soon as in put battery in, no need to even press the power button
All that started by itself yesterday. I thought it was a mechanical fault with power switch, I opened the phone, unscrewed covers, cleaned everything, but found no mechanical issue. I switched batteries, tried starting the phone of plugged-in charger, on usb cable, took out sd card, sim card, put a different sim card in... and nothing helped.
Phone runs on Gingerbread 2.3, stock by T-mobile, never had any other roms on it. Device is rooted.
If anyone has an idea how to approach this issue, please let me know. Or reply with a link to somewhere I can read more. I was not able to find much on this...
Thank you!

The phone sometimes does a reboot loop if u take the battery out of the phone without turning the power off. Just keep trying to turn it on, and eventually it would reboot properly. Take the battery out of the phone for a few minutes, put it back and try to turn it on again. Do this a few times to see if it boot back properly.

Thank you for a prompt reply!
I did take out battery for a long time, well over one hour, and took out sim card and sd card as well. Unfortunately reboot loop started immediately when I placed battery back in the phone. That's what made me think it was a mechanical issue with power button.
I will try keeping battery out a few times again today.
One other thing: the phone had been in hot and humid environment for about 30 minutes before this happened. Not the first time for this phone to experience high humidity, though. However, I did not find any moisture inside the unit.

I had this happened to my phone. Just wait it out and keep trying to reboot, it will come around. Take the battery out and put it back on. Keep on repeating this step.
Also, when the phone is on, try to hold the volume - + and power button at the same time to see if u can get into boot mode.
Also u can use hair blow dryer to blow dry area around the power button.

Or, batt is dead...
You have a stuck power button. Take apart the phone and clean the power bottom with compressed air. Then rapidly push the button in and out for a while.
Resolution:
I took the phone apart, and checked the power button (which had been my first guess), and was seemingly all right.
The battery was also not the issue, as I tried 3 different batteries.
Having no other choice, I put the battery back in, and let the phone happily reboot at its own leisure. After over 20 reboots, the system came on. Then a few minutes later the device rebooted again, and the loop started all over. After a while it booted up again. This time I did not wait for the device to reboot by itself, and I switched the phone off with power button, and then turned back on, and it booted normally. Repeated this once more - normal boot again. One more power off, and I entered the boot menu and did factory reset. Once the stock reinstalled, everything would work perfectly - no more issues with boot loop.
So it seems to me as a software problem more than anything else.
Side note: for the last several weeks the phone displayed strange behavior, that is the screen would light up for no reason by itself, and quickly go off. Sometimes it happened once every few minutes, sometimes it happened several times a minute. Did it have anything to do with the boot loop? No idea. But it strengthens my hunch about a software issue, as that behavior also went away after factory reset.
Sorry for the lengthy post, but since I have not found a similar case anywhere in the forums, I though someone might find this interesting. I do not deal with phones except as a user, but some of you guys do it maybe professionally, so maybe this will be a curious puzzle for you to solve.

Do you have notifications set up? It could notify that u have incoming messages such as a text or an email.

Hardware not software. You had a stuck power button. By forcing the reboot with the power button you unstuck it. If you don't believe it research Occam's razor. Glad you got it fixed(unstuck) though.:victory:
EDIT: Here are some other people who have had the same issue on samsung phones.

[Q] Continuous bootloop so frustrating!!!!

My Nexus 5 is in a Continous bootloop, i literally cant do anything, it tries to boot and gets to the animation screen and then keeps repeating i tried going to recovery to restore a backup but it will go to the bootloader screen for a few seconds before deciding to try and bootup again and failing, sooo annoying. And the thing is I didnt even do anything to it, i was literally using it a few minutes ago to watch a youtube video, then this happened out of nowhere... Anyone have a clue?? This thing is supposed to last me atleast 2 years, no idea how infuriating this is!

since you have rooted i assume you can return to stock configuration!
Help is at hand...literally
This is pretty crazy, I just came on XDA to post about this as it happened to me this morning and I saw this thread so figured you might be having the same problem. My phone went from working fine one second to an unbreakable bootloop the next, I couldn't get into recovery or anything because it would only flash on that screen for a second before rebooting again. In the end I took to frustration, I waited for the phone to reboot and then hit the power button side against my hand (without touching the power button) before it could reboot again and it finished booting into android! I think it must be a hardware problem in which the power button gets stuck down. It seems to have fixed the problem for now at least and I can use my power button properly.
Hope this helps!

[Q] My Nexus 5 rebooted itself 5 times today?

This is the first time this has happened. Basically the screen will just turn black randomly and the Google image pops up for a couple seconds before staying off. The first 3 times it happened I was able to turn it back on by just holding the power button. After that, however, it got stuck in a boot cycle until I plugged it into a charger and tried. So far with the charger plugged in it hasn't turned off yet.
I've attached a screenshot of my battery status. It seems the battery disappeared for a few hours?
Does your battery smell like sulphur?
Sounds like a stuck power button unfortunately. Quite common.
I'd say try flashing stock firmware again with fastboot.... But if it reboots while flashing, you'll be in more trouble.
Let it sit in bootloader mode awhile... See if it reboots or anything. If not, you could try flashing stock firmware. But hopefully it doesn't shutdown mid-install.... That wouldn't be good.
