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.

that worked thanks
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?

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] Nexus AOKP flash

Hi all,
New to forums and to android in general. Wanted to ask a quick question about flashing through CWM. I am on a Galaxy Nexus, running 4.0.1 (ITL41F), on Telus, in Canada.
I used the Gnex toolkit for root/cwm flash. Initially I had tried 5.4 but I couldnt get into recovery mode; the device would briefly show the (unlocked) google screen, and then hang at what I can only assume is an android error screen (android on its back, front panel open with red arrow pointing up?) before rebooting. After that initial CWM install and recovery mode issue, I was experiencing some random restarts and some freezes on my unlock screen. I resolved to try Gnex 5.5, installing that version of CWM and it allowed a problem free boot into recovery.
I have since flashed AOKP (Milestone 3/Maguro) and the install was smooth. However, after rebooting out of recovery mode my device is hanging on the team kang boot logo screen. It's still animated and I assume the first boot after an install will take a considerable amount of time for configuration/etc....but its been about 25min.
My question, then, is should I wait longer? Or does this length of time indicate a problem with the install?
Thank you in advance for any help.

Go back into cwr and wipe all data, wipe cache and advanced - wipe dalvic. Then reboot

Should I be pulling battery to boot? or will holding power turn it off without causing issues from this boot screen?

Hi and welcome

That is no error screen but the stock recovery screen. If you push vol up + vol down +power button again you see the options of stock recovery.

25 minutes is way to long. Dit you wipe data cache and dalvic cache before flashing the AOKP ROM?

None of the above. Scroll through the options with your volume buttons and choose the right one with the power button (in recovery that is)

Sorry, I wasn't particularly clear about my current status.
The device is currently hanging at the team kang loading screen with the animated logo. In order to get into fastboot/recovery I will need to shut down. Is this best accomplished by pulling the battery at this point?
Thanks for the quick responses!

Try holding the power button for a few secs. If that doesn't work: yeah... a battery pull will do the trick

[Q] Brick/bootloop

Hey guys, I've been searching all over for an answer to my problem, so I have looked...
Anyways...I was messing around with my phone (Verizon Galaxy Nexus) and decided to give MIUI a go, so I downloaded, backed up my current ROM and factory/cache/dalvik cache wiped my phone prior to install.
When It booted up, it stayed on the Google screen for a WHILE, so I just left it there thinking it would take a while as these things usually do.
Well, it won't, it sat on the google screen for over a half an hour. At this point I pulled the battery and tried to get into Recovery for a restore/sbf (Powere+Volume Down) and it won't let me navigate anywhere in the menu.
I'm stuck at Start with a notification that says "Downloading...Do not turn of target !!" The only thing I can do is press the power button which of course sends me back to the google logo and I'm at square one.
I've tried the toolkit on my desktop, but that does not work either (I've already set it up, as I used it to root in first place.) Does anyone have any ideas?
Any help would be greatly appreciated, I can normally figure these things out, but im really stuck here. Sorry if this shouldn't be here, Q/A just seemed like the right place
Thanks in advance

To get into recovery, you need to hold volume down AND volume up and press power. (This will take to you to the bootloader, and then select recovery.)

Edit- What they said. ^^^
Have you tried booting it up after pulling the battery? It may boot fine for you now. If not you want to hold volume up + volume down + power that is how you access recovery.
Volume down + power took you to Odin mode.
Allons-y

Thanks man, I really appreciate it!
Its usually always something small...

Odin is a Samsung-specific interface that allows you to flash partitions to your device. For the most part, it is not needed on a GNex, given that we have unlockable bootloaders and can use fastboot. However, it is sometimes needed when your bootloader gets corrupt, and you can't use fastboot.

CM10 Boot Loop? Help!

I rooted my phone to a stock root on my Jelly Bean Galaxy S3. I then installed ClockworkMod through ROM Manager, then CM10. It installed OK, now stuck in a boot loop. No big deal, I'll reinstall to my Kies backup. Doesn't work, I can't seem to get into recovery mode. I hold the buttons, it vibrates, and the screen stays black until I let go at which point it boots to that horrendous boot loop. I really need my phone back!
P.S. Please explain as if I am five years old.

Download mode couldnt get any simpler bud
Edit: just incase if you dont know its down home power button to get to it, find your galaxy s3 firnware (ATT/Bell etc...) and your back stock nonrooted. And then you can root againif you wanna

While in a boot loop, hold the buttons. The phone will power off and stay off as long as you hold them down. Let go of all three, then immediately press all 3 again. When you see a little blue line of letters on the top left of your screen, let go again. Should boot into recovery from there.

Did you read the question bro.. he said he CAN'T go to recovery mode only other option is download mode

No, the option is to boot into recovery and perform a factory reset (which may fix his problem). IF that doesn't fix his problem, he can flash a different ROM from recovery, provided he had custom recovery.
The only difference in getting to download as opposed to recovery is which volume button you use. Chances are if he can't 3 button into recovery, download will be the same result.

Thanks
Got it fixed guys, thanks for the help, now I'm back at Stock Rooted 4.1.1, but am still on the quest for a deodexed rom!

Excellent suggestion - it worked for me

I got a Galaxy S III on 23rd Dec 2012 with Ice Cream Sandwich installed. A couple of weeks later it updated itself with a little help from me to the latest Jelly Bean. Since then it's gone into the reboot loop 3 times without any provocation; i.e. I get it out of my pocket and it's in a reboot loop but it had been fine the last time I used it. I tried pressing various buttons alone and in combination and eventually it came out of the loop. At no time did I have to remove the battery. The only mod I've made to it is the addition of a 64GByte SD card, apart from the upgrade to Jelly Bean. I've seen many posts on this problem but yours is the first that confirms my solution for getting out of it. It's obviously a common problem so somewhere there must be a description of what causes it and, hopefully, how to prevent it as it's a real nuisance when you want to use your phone and it's in a reboot loop. If and when I find a definitive article I'll post here again.
Thanks MrHaley.

[Q] Can't get into recovery, phone is constantly force closing setup wizard

Ok so I installed Liquid Smooths new beta rom, it was running fine but didn't have GAPPS, so i went and flashed GAPPS and now my phone is stuck......
When it loads the rom it keeps saying "unfortunetly setup wizard has stopped working" i keep clicking ok but the same message keeps popping up over and over again.....
I have tried the vol down, powre and home button to get into recovery but all it does is turn off the phone
Pulled battery and tried holding VOL DOWN+power to get intro recover but all it does is vibrate every few seconds.....
I am stuck and have been trying to get my phone operational for three hours, anyone care to help me? I have tried ADB but it cant find my device and i can't get into the settings of my phone to turn on debugging mode

First, did you flash the correct gapps? You have to make sure what you are flashing is correct for the ROM before you flash it.
Second, you need to turn the phone off, then press power + volume up + home until it vibrates and then release to access recovery. To access download mode, its the same thing only with volume down.
Third, a bit of advice. I don't mean to belittle you, but it doesn't sound like you did your homework before you started flashing things to your phone. You need to read around a bit and get a good grasp of the basics, or you will end up in trouble, whether it be as simple as a bootloop or as bad as a hard brick. I hope you get it fixed quickly. Good luck!

Thanks, I finally got into recovery mode by holding the three buttons then letting go right after it vibrated and pressing again.... weird..
For the most part, i read every single post in a thread before i flash a rom, I have been flashing roms for years now ....... I guess i got comfortable and flashed this "beta" rom(stupidly) not thinking anything of it..... and no i didn't even check if it was the right gapp, i knew it was for 4.2.1 and i figured the beta was the same.
I am not back to a working rom, but now my phone is only able to get Edge speed, is that a modem issue?

That's an imei issue. Look around there is a thread about it. Happened to me but that got it all fixed. Under phone settings about phone if your imei is 0 you need to inject it back. Hope this helps
