Go into recovery and clear the caches, do a data factory reset and reboot.

Then you`ll have to reflash the factory image bro (icluding userdata.img), look here for how to do that http://forum.xda-developers.com/showthread.php?t=2513701.

Probably by Art as it is still work in progress that caused an app or apps to not be able to load and now tries to reboot..

Next time this happens, just dirty flash your current ROM over the top and you'll be fine.

Need urgent support. My Nexus 4 running on stock 4.4.2 got boot loop with 4 colored bots after enabling ART Runtime. After enabling ART, phone got restarted and recompiled all apps, but on second boot it got stuck. Please advise what to do now? I have not rooted by phone…it is completely stock.
Appreciate your quick response.
Same bootloop after switching to ART
I switched to ART and not I too am stuck in a boot loop.
I don't have USB debugging enabled, so none of the recovery tricks and tools work.
How to I get out of this?

Follow the thread a few posts above yours on flashing the stock images.
I had a similar issue, after enabling ART and rebooting...
The phone was stuck just after the "apps optimization" step, and after a forced reboot, it was stuck on boot (on the 4 coloured dots).
Hopefully, a factory default in TWRP fixed this issue. It is my first day with this phone so I didn't mind to lose everything with the factory default.
I just did the switch again to ART and this time, it worked
:good:
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.

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.

Hello guys,
so recently my Nexus 5 crashed while streaming some videos and got into a bootloop. I could access fastboot, so I tried flashing stock 4.4.2, wiping data, wiping cache. The phone tried to boot a few times and eventually managed to do so, only to start rebooting while logging with my Google account. After a few loops it managed to boot again, and for a while it seemed as everything was okay, until I tried to restart it. Now the phone is just looping and even after 10 minutes isn't able to boot successfully.
At first, most of the time the phone rebooted on the Google logo, but a few times it got to the animation, froze and then rebooted again. Now it's just the Google logo.
Do you have any suggestions what to do? The phone right now is on factory 4.4.2, unlocked, so I'm starting to be afraid it won't be fixable.
Thanks for any ideas or help.
how did you flash the stock images?
I followed this tutorial, through flash-all.

Boot into the stock recovery and do a factory reset. Problem solved
Wiping data/doing a factory reset is actually one of the steps in the tutorial, I already did that, it still doesn't work. Hell, I even tried it again now, still nothing.

How long are you Leung it boot? The first boot will take awhile, give it 5 minutes
I left it for about 10 minutes before, but to no success. It's not like it's actually doing anything, it just gets to the Google screen, turns off and tries again, over and over. I'll leave it running again, maybe it needs some really long time.

It's not boot looping if it turns off and back on again. You have something else going on. I'd re-flash the factory image again. I think something went wrong there.
Oh, sorry. I originally searched for rebooting related problems but only found bootloop, so I kinda assumed that's what it meant. Whoops.
I'll try the reflashing, then.

A boot loop is when it gets to the boot screen, the four Google colors and just hangs there without going any further.
Flashed again. The whole process goes smoothly, no problems at all. Did another factory reset as well. Phone is still rebooting.

So it tries to boot, shuts down probably vibrates and then restarts all over again? Have you tried to re-download the factory image? It could be a bad download. Also use 7-zip to extract it.
Are some phones maybe over heating, I wonder if you cooled phone off, if it could finish booting then?
I might try that, shut off phone, let it cool or help it cool with fridge in sandwich bag or something then retrying in 20 minutes or so?
That is, if you haven't had success yet.
I'm not sure how to read last sentence if successful or not?

Yes, it gets to the Google logo, turns off, vibrates and starts again. The weird thing is I actually managed to make it work before making this thread (it restarted a few times, froze and restarted on the colors and like the 10th try was successful), but after turning it off I'm not able to turn it on again. So the image should be ok. I can try it, of course.

The phone is still not working, but the temperature isn't high - it gets more heated when I'm charging it, right now it has room temperature, so that shouldn't be the problem.

No, I've been just flashing them. I thought overwriting it would be enough.
Is it safe to go simply fastboot erase partition, then fastboot flash partition? Or are there some I should not be erasing?

You can erase then all. System, cache, boot, userdata, recovery. You'll flash then all too. The order doesn't matter.
Hi guys,
Today my phone started acting weird. After I locked the screen or it locked after 15 seconds, it wouldnt turn back on. Only way would be resetting the phone. After a couple of resets the screen just shows like a old tv with no signal(TV noise?). If I let the phone sit for a while I could turn it back on and get to recovery but it wouldnt go into the OS. I tried doing a factory reset on the recovery and I just get stuck on the "formatting data" screen.
Any way to recover from this?
Phone is completely stock. No root, locked bootloader,etc.
Thanks.
For how much time are you using your phone? It's sounds to me as hardware failure.

So I was playing around trying to get Sound MOD to work(dont ask me y..I was bored) And I have bricked my phone. I am stuck on the white HTC screen the one at the begining of the boot..the one that says this build is for development purposes..blah blah. and it is just stuck there. Adb wont find device or nothing..I am truly screwed..yes?
Well, ADB wouldn't be able to do anything at that point anyway. It's not fully booted, or in the bootloader.
Have you tried powering it off, and booting to the bootloader? From there recovery, do a factory reset, and see if it boots then?

Ok so update: I was SOMEHOW able to get into recovery(TWRP) but no matter what i try to do it just reboots back into recovery..any ideas?
EDIT: gonna try verizon RUU. Fingers crossed
Just a thought here. TWRP can install from USB. I have flashed from a thumbdrive in the past on an S3. You may be able to do same. I know this is a shot in the dark but may help.
Will it just sit at the recovery screen or does it boot before you touch anything? If it will sit at the TWRP main screen you should be able to boot into hboot via adb and try a reflash of twrp or CWM. Your recovery may be corrupt.
You're definitely not bricked. You're catching breaks left and right.
