Galaxy Nexus stuck on Google logo boot loop help [GSM]

I am running the stock rom without root and unlock and I got the 4.0.2 OTA update 3 days ago. Today when I do the pattern unlock my phone froze and reboot. Now I cannot get pass the Google logo boot screen.
I am able to get into the recovery mode but I don't want to do a factory restore as I don't have anything backup yet.
Is there any solution to this boot loop problem? I am surprise that I am getting this problem as I am running the stock rom without any root / mod.
If there is no solution to this, is there any way I can backup my phone before doing the factory restore?
Many thanks!

You can back up via adb. Try searching in the General threads, since there's a long topic on this...
Good luck!

Thanks, I do find information about backup, but I can't find anything regarding the bootloop...

When i got stuck at the Google screen with a bootloop i booted into the bootloader/fastboot screen with vol up+down power and i redid the one click all process and it basically rewiped my device and put it back to working again with unlocked bootloader rooted etc....
All you have to remember is what build number you have and let the toolkit work its magic.

Sorry, forgot to mention. You're probably gonna have to wipe via recovery - which is why I pointed you to a back up...

I can't find a way to backup without going into Android. I can only go to Fastboot Mode.
Anyone know how to backup the file using abd without getting into android?

Why did make 2 threads about this. Unlock the boot loader and use adb to flash your stock. Image files. You will loose all data unfortunately but I think that's the only way to fix it.

Ok I'm stuck with the same problem now. I wanted to flash a ROM, so I downloaded AOKP, flashed it and rebooted and the phone refuses to boot past the Google logo and keeps rebooting again and again. I am able to get into the recovery. I have flashed the ROM several times and its still the same. I have done a complete wipe as well. Still no go.
Fastboot command doesnt work in the bootloader either. I have made sure the drivers are installed, still there is nothing when I type fastboot devices. If I type any fastboot command it just says <waiting for device> or something like that.
Any other suggestions? :-s

Help urgent!!!!!!! Gn stuck on google symbol

So I was trying to put JB on my GN using this:
pcworld.idg.com.au/article/429778/how_update_your_galaxy_nexus_jelly_bean/[/url]
I reached to apoint where i had 4.04 yakju, but when I put the file to get JB, It said error and aborted, i went to wipe data and reboot, wipe data worked fine, reboot led me to the google home screen and is stuck there.
I can access fastboot. Recovery mode takes me to that android with the danger sign, doing another reset doesnt work, clicking reboot doesnt work.
I'm pretty nooby at this. I read a few other forums and they said something about flashing a new rom or something but I don't understand.
Please help! The phone isn't mine! Need help ASAP before owner finds out I messed up their phone, thanks!

If you can access fastboot and your bootloader is unlocked just flash a stock system image.
These are the reasons people shouldn't just one click everything they do. If you understood how fastboot worked you would be golden.

Reflash recovery. Then mount USB storage and then get a ROM on there and flash it.

The site I went to dumbed down everything, and all i had to do was input numbers into some program. I double checked what a fastboot was. I definitely don't know how to work that. I mixed up the fastboot with the bootloader...

how do i reflash recovery and get a rom on there? I know this is asking alot....sorry
My bootloader is unlocked but im not rooted. I will (figure out how to) root if needed.

Open up a terminal on your computer use fastboot to flash the recovery image.
Since you didn't take the time learn what you were doing to begin with, I would take the time now to go read. The answers are easily found with google, or searching this site.
Roughly, install adb and fastboot on your computer, load drivers for your phone, download the proper recovery and put it in the fastboot directory on your pc, plug in the phone boot to the bootloader
open term
./fastboot oem unlock
./fastboot flash recovery <nameofrecoveryimage>

I reached the fastboot part, but when i type in "fastboot flash recovery (file name) it says it cannot load file name...
What is the proper file that I should use? Running 4.04 YAKJU looking to just recover the phone back or switch to jelly bean, whichever is easier. (jelly bean if they are both the same)

okay okay okay, i think im almost there...got a rom and extraced it, i know how 4 files:
Boot 4,148KB
Recovery 4,478 KB
System 316,112 KB
Userdata 137,555 KB
Which one do I put for fastboot oem recovery (fileimagename)
Thanks

Stuck on Google screen
Background: GN is unclocked and rooted. I've had quite a few devices and have rooted them all and run custom ROMs. I am fairly familiar with all of the tools needed, but by no means an expert. I have the Android SDK with adb and fastboot installed on my Win 7 x64 machine as well as the samsung drivers. I loaded a Jelly Bean ROM the day after it was announced at Google I/O and ran it for awhile before I started having touchscreen issues. I removed the battery and restarted the phone and had no problems for about a week or so.
Problem: I started having touchscreen problems again, but figured it was perhaps due to the early version of JB that was ported over from the GSM version (I believe). I tried a few other versions that were released later and they would work for a few days and then the touchscreen issue would pop up again. At this point I started thinking it might be a hardware problem because if I twisted the phone (weird, but it worked) the touchscreen would respond. I flashed another version of the Jelly Belly ROM yesterday (//rootzwiki.com/topic/28677-rom-jelly-belly-v33-07122012-jellybean-411-pure-aosp-its-all-about-speed/") to see if it would work by chance. Unfortunately, I still encountered the touchscreen problem. After rebooting a few times my GN started bootlooping and would not load into Android.
Actions: At this point I tried to recover from a backup, but much to my dismay it failed (don't remember exact error). I tried a few other backups with no luck. I tried reflashing another ROM, no luck. Then I started seeing some errors when booting into recovery (E: can't mount cache/recovery/log. Around this time I also noticed I was getting errors with sdcard. I decided to take the phone back to stock using the verizon ICL53F factory image. I tried via numerous toolkits (Odin, Galaxy Nexus Toolkit and directly from fastboot) and have been unsuccessful. I've searched every forum and have literally tried everything I with no luck. I can flash new recoveries, but it doesn't solve my problem. Right now phone is back to stock with stock recovery and just bootloops at the Google screen.
I assume my phone is completely hosed, but am hoping someone might know something I don't and might be able to help me restore this phone.
Edit: I tried flashing an imm76k factory image via fastboot and was finally able to get in. I must have had a bad icl53f factory image...close call.

[Q] T-M Not Booting Past Samsung Screen; I have troubleshooted

All,
I have used my GS3 for awhile now without issue. I'm abroad for the forseeable future, so I've only been using it for Wi-Fi calling and internet/apps. Regardless, Kies NEVER worked for me, and my computer never recognized the USB device. Up until recently, I've just used my iPod for music, so no problem.
Fast forward and my friend, who also has a GS3, tried to update my drivers and root/flash my phone so I can drag and drop files the way he does with his. I let him do this because I'm newb to this, and because he assured me he knew what he was doing as he'd done it to his and his girlfriend's phone.
As it turns out, he has an international version (he used ToolKit instead of QCom ToolKit) and he tried to root the wrong files to my phone. At first, I thought it was hard-bricked (which really puts me in a tough position since I won't be back in the States until January), but I don't think even his root attempt worked properly.
So where I'm at now:
The phone will not boot up. When I turn it on I get the Samsung Galaxy S III logo, but android never loads. The phone will charge via USB and the wall.
I can access recovery bootup
I can access download bootup (the ability to do the two above lead me to believe it isn't hardbricked, I read on these forums, if I can get to download bootup then it's probably fix-able)
I've combed the forums and the internet, in general, for a fix. I downloaded the factory restore settings from samsung-updates (sorry if I cannot plug this site, it's not intentional, simply to provide as much info as possible), but Odin always "FAIL"s when I attempt to apply it.
Additionally, I've attempted to recover via recovery bootup/reset, and then load the factory restore setting via Odin. This did load them, but the phone did not boot up.
QM ToolKit was acknowledging the phone, so I attempted to boot the correct files using ToolKit (the ALLINONE option) and this worked correctly, as expected via QM ToolKit. But still the phone would not boot up.
The phone sits at a black screen after the GSIII logo with the blue LED lit up.
Any tips or advice would be appreciated. I'm in quite a situation.

sadly i have the same problem, this happened randomly and cant get my device to boot

If you Odin tmo stock image tar and odin recognized your device and all went well then boot into stock recovery factory reset then reboot. It should boot up if all is well. When you plug to pc does your computer recognizes it?

Provided your boot loader and download manager partitions are working(as it appears to be the case) you can get your phone back to a "working" state.
What I suspect happened is that at some point during the process of playing with it, your partition table got hosed and now android is borked. I would recommend re-partitioning it but I don't have enough info around me and available to give you instructions to do so. I'll do some digging and try to get back to you.

[Q] Stuck in Clockwork recovery -- can't flash roms

Hi there,
I've been trying to fix this issue for a while now and I haven't seen any guides on my particular issue.
Basically what's going on is I tried doing a factory reset on the phone while having cyanogenmod flashed and when it booted, it would keep booting up in the recovery.
There seem to be no backups or roms on the phone.
Now here's the kicker, when I try using the Nexus root toolkit, it doesn't recognize my device whatsoever. I've uninstalled the drivers fully and reinstalled them and still nothing.
When I plug the phone in, it doesn't show up as an external source (other than in the device manager with a "!" by 'galaxy nexus'), so I can't just put a ROM on there and try flashing that.
I'm stuck. I have no idea what I can do to get this back up & running.
It's a GSM phone, being from Canada I believe it to be Yakju...
Anybody have any ideas? I really need this phone to start working!!

Have you tried the method in this tutorial?

you may bring ti back to samsung customer service.

Soft bricked zenfone 2. Need help. Need USB Debugging

I have a rooted zenfone 2. I checked for an update. Not knowing the risks of updating system while rooted, I installed the update, and now my phone is stuck on the boot animation screen. It is stuck on "Asus In search of incredible" screen with the turning gear. I can access fast boot mode and recovery mode, but can't start the phone. My phone has Android system recovery installed, not ClockworkMod or TWRP. I tried to install a different recovery, but my PC doesn't read the phone. I thought that wiping the data and cache will help, but didn't. Help me. I'm a 15 year old noob. My parents will kill me!! Also, I haven't tried to install any ROM's on it. So that's out of the picture.
And neither adb, not fastboot can detect the phone.
My phone is rooted, but the bootloader is not unlocked. I was going to unlock it, but thought of backing data up first. I was trying to find the backup app, but accidentally tapped on system update app. I thought there wouldn't be any harm in checking for an update... Apparently their was a lot of harm.
I also tried installing twrp recovery, but it gets stuck on "Waiting for device"
I'm in dire need of help.
I just need to find a way to switch USB debugging on...... That'll fix all my problems
thanks in advance.
I have the Z008 model, NOT the Z00A.
