Galaxy Nexus in reboot cycle

Hi
My Galaxy Nexus has just started into a constant reboot cycle. The Google logo comes up and the the multi coloured animation thing like normal and then it goes back to beginning.
I never get to enter my pin or anything.
Has this happened anybody else?
It also gets quite hot after been in reboot phase for 20-30 mins.
Thanks
Brian

Need more details: what ROM/kernel you're using? Do you have ClockWork Recovery installed? What did you do to your phone before this happened?

Im not sure on exact details other than its as it was when I bought it apart from 4.0.2 is installed
I didnt root it or change radio etc
I was just using it as normal, was going in to check battery level I think
ClockWork isnt installed
If I hold down power button and volume button and go into recovery options reocovery mode doesnt work, restart bootloader doesnt help either
Only other options I have are Start and Power off
When I try and go back into those options again all I get is a screen with green Android and Start > Downloading > Do not turn off target
It can stay in this screen for 5 mins or more and go nowhere
This happened earlier on as well so I just turned it off
I tried the same procedure again and I got the recovery menu again but it still didnt work and then tried it again and I just got the Downloading message again
Not sure if any of that helps, I cant check the kernel version anywhere right now.
Oh and its the GSM release of the Nexus

Try removing the battery and then turn it on, works for me; have you installed some new apps before this happened?

I choose recovery mode and the phone restarts, Google logo comes up and it then goes to a picture of android robot with a red excamation mark over it
It just stays there on that screen for about 2-3 minutes and then retarts
After restarting it goes through sme sequence as before constantly going from Google Logo to multi coloured animation and then restarts again. At no stage do I get to login screen.
Only other option I get when I hold down power button and volume button is to restart bootloader, start and power off.

the hardest part was getting my laptop to pick up my phone in bootloader mode but my laptop is getting old and on its last legs, the usb ports are dodgy for everything

Just to warn you, there's a good chance it will happen again eventually. A few days ago it happened to me for the second time (completely stock).
I decided this time to root it and install a custom rom seeing as how I'd have to flash stock again anyway. I'm hoping that whatever bug that caused it has been fixed in 4.0.3.

how often has this happened to you where the phone goes into reboot cycle?
are you on 4.0.2 as well I assume its the gsm phone as well?
its handy to sort but a pain in the whole having to install all the apps again

The first time it happened was the 11th Jan, on 4.0.1, and the second time was the 29th Feb, on 4.0.2. And yeh it's GSM.
Yeh exactly, sucks having to install apps again etc. Now I'm rooted I've got a nandroid backup just in case it happens again.

[Q] Bricked my Desire HD.

Hi, first off I don't really know what all the terms mean , but my phone is rooted, and has a ROM? installed, I'm not 100% sure on what it is as I've forgotten, but I think it is Cyanogenmod?
The past few weeks my phone has been restarting randomly and freezing every now and again. This morning when I tried to unlock it the touchscreen wasn't responding, and this had happened before. I took the battery out and tried to turn it back on. I see HTC splash screen pop up, and that's all I get. I've tried turning it on whilst plugged in charging, and still nothing. It's all fully charged. I've tried turning it on whilst holding the volume down button and it vibrates 3 times and still nothing.
Thanks for any help!

can you still go to bootloader then recovery?

Hold the power button and volume up to get into bootloader, then select recovery. Try to clear cache and davik cache then restart. If its wont work u should freshly reinstall.
I was in your case when using Jellytime R11...my phone started and freezed at boot screen. No matter how manytimes I removed the battery n restarted the phone just stood still. All I can do is go to recovery...

I've just tried that, and unfortunately it didn't work. When I do that the phone vibrates 3 times, and the orange LED flashes, and has been flashing for around 5 minutes now. The screen also doesn't turn on at any point.
Thanks for the help!

Thanks, I've looked around and can't find a tutorial on how to do that on a Desire HD. Do you know of one, or a good generic tutorial I could follow?
Thanks again.

Take the Sim SDCard Out as well as battery. Wait a few minutes then only replace the battery back and see if it fully boots If it does then power down the phone pull the battery wait again a few minutes then boot with the VOL DOWN key and then factory reset it.
With this done its one more battery pull and boot again it should be fine after that.

Unfortunately that didn't work. I'm not sure if this is of any help, but when booting normally, almost immediately after the white HTC splash screen, the screen flashes blue for half a second.
Thanks for the help!

No clue how I've done it, but I've been pressing button for the last 10 minutes and managed to get in to what I believe is the bootloader? It's a white screen with Fastboot, Recovery, Factory Reset etc and the options. What shall I do from here?
I wiped the cache, and booted and then it froze saying "Android is upgrading, starting apps"

This step takes a while. But if you could get into the bootloader which is Fastboot Recovery and Factory reset you could of choose Factory Reset to see if that fixed the issue.

yup, since you can now access your bootloader, from the recovery just flash your rom, remember to do full wipe first, data, cache and dalvik cache...

Help. S3 keeps rebooting

Im running jovy stockorama everything has been great. Until today idk if its rom issue or just the phone issue. It keeps booting to the galaxy s3 screen and vibrates and turns on again its a loop. I tried going into recovery it doesnt work also cant get into download mode. Please help (

The ROM is dated you may want to try another ROM.
Pull battery out of phone and put it back in and do the following:
For recovery: hold volume up, home button and power button until you feel the phone vibrate and you see small blue text in the upper left side of the screen.
For download mode: volume down, home button and power button until you feel the device vibrate.

If absolutely nothing changed, and you can test another battery, it's a hardware failure most likely.

Possibly the power button is stuck keeping contact too. Been seeing more of these recently.

Hey! I broke my power button yesterday (it is stuck being pressed, so the phone constantly reboots). My questions for you are:
1) How did you pull the power button out?
2) How do you turn on the phone without the power button?
Thanks!

First off make sure you are flashing through TWRP correctly .
1) Flash Devlic Three Times
2)Wipe Cache Three Times
3) Wipe System Three Times
4)Wipe System Three Times and make sure you have your ROM backed up and have the correct Gapps.
Doing all of this will fix your problem I had the same problem too.

Careful there! This is often a hardware issue. If he does this and it is hw, it may make things more difficult.
Make sure it's your Rom/firmware causing the problem first.

True, one time I did download a Cyanogen ROM my cousin sent me but the ROM was a dud. At first I thought I had bricked my phone so I spent sever hours on twrp flashing different ROMS over and over again that I had and I installed the wrong gapps so my phone died and I had to take out my sd card and download a different ROM and I fixed it. Basically just be careful where you download your roms from.

stuck on start up screen

after flashing this rom and gapps [ROM][AOSP][4.4.4][Unofficial] Beanstalk 4.4.065 [10-8-14][ALL M8] it started up and is now stuck on the start up screen and every thing i try doesnt work to get it to recovery or bootloader screen i hope some one can help me get my phone back

Hold down the power botton +vol. up for about 20 seconds. When the screen goes black switch holding vol. up to holding in vol. down.
You should boot into fastboot.

If you're not on 4.4.4 firmware you should update to it. It's already a well known fact that running ROMs with out dated firmware WILL result in excessively long bootup times(10mins + ) .

Press volume UP and Power for 10seconds, once the screen goes dark immediately press Volume Down to go into bootloader.

Then just try it again.
Did it actually start up again or just shut itself off? if so you can still just press Volume Down + Power to get into bootloader.

Once it reboots you won't really be able to get in, well I couldn't when I tried. As soon as the screen goes dark you should immediately have the volume down key pressed, I'm talking about a second at most in between.
If the phone is completely off it's easy enough to just hold volume down and power for a couple of seconds until it goes into bootloader. When you do the hard reset you have to hold the power button and slide down to volume down quickly before it boots up.
You didn't still have fastboot checked in the settings did you?

OH SH*T! I still have mine checked. It doesn't work any more for me (normal boot times), but I haven't been unchecking it when messing with stuff because I'm not realizing/ forgetting that it is on.
I should probably fix that before I get myself into trouble.:good:

I'm just curious, was your phone fully charged when you were flashing the ROM? It sounds like a battery problem, but I could be wrong.
Always make sure you have lots of battery before flashing anything. The way it won't stay on is really weird. You could try the ROM's forum. Maybe you might find an answer there. Sorry.

HTC won't boot

I tried to root my HTC Desire 820. While rooting it with supersu i checked reboot system instead of wipe cache/delvik (which is probably why it wasn't detected as rooted). I noticed it, so I went back in, and while choosing .zip directory i went away for ~5mins and now my phone doesn't boot (LED doesn't blink either); battery is well over 80% and charging. What should I do?

Well if I had to guess I'd say it's a screensaver because I didn't really press anything; I can't access it in anyway, unless there is a special type of button combination?

Try holding power and VOL+ together for some times. It should then bring up the HTC boot screen. Then the device should start boot normally again.

You are welcomed?.
For most of the Android device that has a non-removable battery (not by screws), VOL+ and Power button is a universal trick to force reboot/shutdown your device.
