If its doing it before and after, I suggest a warranty exchange
Welcome! look here: http://forum.xda-developers.com/showthread.php?t=1436052&page=7
try using a more stable rom e.g. a blur based rom or try a diffderent kernel.
As you will find from other threads, this is totally a hardware issue, and Motorola is replacing them very easily.

Nokia reboot problem when trying to update

Hello!
I have a strange problem with my phone it wont update to latset firmware without get in some kind of boot loop.
The phone was runing the lastest firmware 1232.5962.1314.0017 before the problems started, it all started when some systems apps like camera, settnings, messeging. etc, stop working. All that showed up when entering the apps was a black screen say something like "reconnecting" and then it jumped back to home screen.
So I restarted the phone but then went in som kind of reboot loop where it wouldent go past the nokia logo. I tried everything soft reset, hard reset. The last thing I tried was to reflash the phone, I tried diffrent ROMs and it finaly worked with the ROM 059Q5C6 RM-821 GLOBAL BLACK SWAP.
The phone is runing now and almost all functions work exept camera and automatic brightness (all that I discoverd so far).
Its currently running the 1231.5951.1249.1004 firmware.
But like I said now when I try the update the phone it goes to the same boot loop state.
What should i try next?
Is the thread in the right place?

Same thing happens to my phone!! Did not think that it could be the latest firmware (1308 for me) could have caused it since I don't think there are a lot of us affected by it and my phone has been running fine for months after the update! I've restored 5 times, by the time I thought to flash it, it wouldn't charge anymore.... I'd sent mine for repair now... Have you fixed yours?

[SOLVED] [Q] Phone rebooting with high CPU usage

Hello!
A few days ago, I used CM12 Unofficial with Android 5.0 and ArchiKernel, and it worked fine. While I was using it, the phone turns off and reboots. Showed the "Samsung Galaxy SIII" logo and rebooted, in a bootloop.
I flashed the rom back, wiped all, and nothing, the bootloop still happened. I flashed it with Odin, to Android 4.1.2. The phone works, but when I use it some minutes turns off and goes into a bootloop. When I run an Antutu Benchmark also turns off.
Researching and playing with kernels, adb, and roms, I discovered that turns off when the processor runs at over 1200MHz. This happens with every kernel, also stock.
What happens and how can I make it work normally again? Thanks

The problem was the battery. After changing the battery the phone worked fine again.
It's obviously a hardware fault, you can't fix it.

Quantum 400 - Newly installed 4.4.2 and it's restarting all the time

Hi.
I had a Goclever Quantum 400 but I've buy a new phone. And I want to give that Q400 to somebody from my faimlly but this device from last few days starting to act weird. Apps won't run and stuff like that. I can't do a factory reset because after restart it's still was the same. So I try to install a new android from here - goclever.com/uk/products,c1/smartphone,c8/archive,c100/quantum-400,a331.html#support
And it's the installatioi process goes well so after that I turn on device and put my google account etc. But after that device restarts every time. Once it after few second after turn on, once its minute after or something like that.
And now I can't install any other android because it still is the same, even when updating goes well. I can't turn recovery mode either.
Any help?

Random Restarts (Long story)

Hey guys! This is my first thread here, but I knew this site before. I've got an M4 Aqua E2303, Android 5.0, Build 26.1.A.2.167 (upgraded from .99 with TWRP to keep the root.).
The story : I've got this phone like 4 months ago, I was so happy etc... After it updated to 5.0 it kept restarting randomly. Total random, when it was not under using, if I use it, it does not restart itself. Sometimes the restarts occurs when it's under charging, and sometimes when I want to unlock it and use it, and sometimes total randomly, and sometimes it shuts down. For different verions the problem was different too. On 26.1.A.2.99 it was the worst, it restarded and stuck on the boot screen until reached 0% battery. On 26.1.A.2.128 It turend off the screen, but the phone was running and the LED was red (even when fully charged) and only started with the hard off button in the SD card slot.
I've got the default "Diagnostics" app, now it says that the Phone got system errors 42 times in 10 days. It was worse before (over 140). But it doesn't say why did it restart, I'm hoping for help from any of you, who had this issue and solved it, or someone who knows a better diagnostic tool that will explain what caused the system fault.
I appreciate all the helps!
Have you performed a factory reset? (It will delete all your data and apps)

Yes, when the phone was new and the restarts were annoying. It fixed it for 1 day. The next day it was restarting again.
This would point to an app you've installed causing the issue. Factory reset again and install each app one by one until the restarts happen to find out which.

If you used the pre-rooted zip to maintain root while updating to the latest android, this will fix your rebooting problem. Follow this guide:
