Hi
This is a well known issue with the nexus 5. My device permanently starts rebooting. The google Logo occurs and then it rebotos again. There is no start animation. If I press the power and volume down bottom I just see the bootloader screen and after half a second it reboots. I can't do anything.
My phone is rooted (no custom ROM) and before I go back to the shop I want to unroot it. However, with this behaviour I'm not able to do it, or is there any chance? Does someone know at least, how I can boot normaly to unroot it.
thanks for your help

Hello, take a look at this thread http://forum.xda-developers.com/showthread.php?t=2513701
Is this really a well known issue? What were you doing directly beforehand? What have you tried to do to fix it? Have you tried using fastboot commands to reload factory images? Are you a toolkit only user? Have you tried a factory image through that?

Well IMHO it is a well known issue (see for example the wikipedia page or just have a look in tech forums). Directly before, I was writing an SMS and put it in my pocket (everything seems fine at that moment). 10 minutes later I just want to check my SMS and then it was already rebooting all the time. This was not the first time, I had this issue 2 todays before, but after approximatley 20 reboots it started correctly.
So far I was not able to use fastboot commands, since I can't enter fastboot. I didn't use a toolkit.

Thanks for the link. I will check it later, 'cause I have to leave. I will write again and let you know if I'm able to enter fastboot.

I have never heard of the issue where it was only rooted and it just randomly decides to reboot and keeps doing it for no reason at all without the user flashing something that it did not like. So are you saying that you cannot even turn the phone off it just keeps going into a bootloop and trying to enter fastboot does nothing?
I don't think this is a really well known issue.. Have not seen to many support threads about this.

If the wall charger is plugged into the phone, the nexus just starts rebooting. I see the white Google logo and after one or two seconds it reboots. Sometimes you see the boot animation (4 circles) but after a short time it restarts the phone not able get to the point where you unlock the SIM. Trying to get into fastboot mode is also not possible. The fastboot mode appears but after half a second the phone reboots again. If the nexus is not connected to a charger it repeats rebooting for about four times after that just a black screen appears. If I'm not able to get into fastboot mode I can't unroot the phone, right? So the links you shared are not useful in my case
I have the nexus now over a week and the phone worked perfectly fine the first week.
I have uploaded two films of the problem to youtube, see this link. One film is with the nexus plugged into the chrager and one where it isn't.
That is very strange.
I would definitely use Madpiercing's post and link to http://forum.xda-developers.com/showthread.php?t=2521691&page=3 to try and fix it.

The very strange thing is, that it worked well over a week. the random rebooting starts two days ago, first time it starts again correctly after 5 min. Now it seems to hang in a loop.

After a while I was able to get into the fastboot mode: I plugged my nexus into the wall charger for about 1 hour. Then it booted correctly. I had plugged my nexus into the charger before (over night) without leading to the same result. It seems that it just starts working correctly as random as it crashes
Do you think it is a bug in the bootloader or that something happened while to rooting the phone?

It's most likely a hardware issue, bad cache memory on the cpu. I'd rma it.

make sure you unroot and relock the bootloader and do this now while it is working.

I believe it's fixable
So try this.
Keep pressing power button till shut down,then try to enter bootloader by power button + volume down.
The guide you linked....if followed properly will not brick you.
Any more details? What you did exactly....errors....anything??
Did you press the power button for a very long time to see if anything happens?
Are you sure its fully charged? Any sign of life when plugged into charger....or computer???

I get a sound when plugged into the computer, I'm not sure if I extracted the right files to the platform-tools thing or whatnot, I also entered "fastboot flash boot boot.img" not sure if any of those was ment to be the name of my image.
This is what my platform-tools folder looks like.

Edit: Holding the power button for a very long time got the phone to show the "Google" logo again, I'll try and get it to boot into bootloader.
The phone is now in bootloader.

Try booting in safe mode. If it still reboots, then flash a factory image with fastboot. If it still reboots then, you've got a hardware problem.

If you flashed a factory image and it still does it, then it is likely a hardware issue.
Replying to your PM- Boot into safe mode by pressing the power button, and when the reboot menu comes up, press and hold "Power off" until the option to reboot to safe mode pops up. Then just hit OK.

I am now safe mode
What does it do?
Keep it that way?
Check with a recurring problem?
I get calls when I'm safe mode?
It does not interfere with my work when I device safe mode?

Safe mode boots your phone without any 3rd party apps or non essential software. It basically only loads the stuff your phone needs to run which will help to eliminate any apps as the culprit. Yes you'll still get calls, but any apps you use won't be accessible. It's not something that's meant to be used all the time, just for troubleshooting. So, if you still get reboots while in safe mode, that means you either have a hardware problem, or a firmware glitch. But since you said you already flashed the factory image that pretty much rules out the firmware, leaving hardware as being your issue.
having a real problem here. the device will not charge, and when i plug it in when turned off, it will not stay on the charging screen, but resets constantly. please help.
the device has an unlocked bootloader and is running cm13 nightly

Sounds like a kernel issue. Go back to stock pb1 and see if the same issue persists.
If it does then you may have a hardware issue.
how might i do that while keeping the bootloader unlocked? is there an odin file without sboot.bin?

Flash any stock based rom.
And the stock kernel.
This sounds more like your power button is stuck. I haven't had it happen on an S5, but I've experienced it on the S4. Tap the power button side of the phone down on a hard surface, and that will usually free it up. You might need to use some force. I had to slam the S4 pretty hard against the table to get the button freed up.

Hi mate
You need to enter the old Google password of the phone , in order to avoid this you should had disable it before you factory reset the phone

I appreciate your feedback, but there's nowhere to enter a password. The screen is locked and I don't have the passcode. I'm trying to wipe it but can't. I can't flash it because FRP lock. So the phone has not been reset yet because I cant. Thanks tho

You mention it was on airplane mode , no wi-fi so your phone boots up , right? usually when it first boot it should ask you introduce the password of your associated email ( google most cases).
But explain what happened , how you got FRP without reseting the phone ?

It sounds like you're dealing with an MDM lock. FRP doesn't prohibit stock firmware from being flashed, but MDM does. And an MDM lock would also prevent it from being factory reset via the Recovery menu. I was asking for the Download mode picture in order to confirm the MDM status
