Desperate Help Needed!

So I am the proud owner of a shiny, new Galaxy Nexus (GSM). Unlocked the bootloader and installed CWM recovery and was doing great. Today I decided to install the volume fix. Installed the zip through recovery, completed and rebooted. The phone got stuck in a bootloop over and over and over and over and would not boot Android at all. Did a ton of research here and everywhere and, in a panic, I booted into CWM recovery, reset the cache & did a full factory reset. NOW, the phone will not go past the Google bootscreen with the unlock symbol, no matter what I do. AND, I can't even flash the original google image because I can't get in to set USB debugging so my computer won't even recognize the phone (FYI, I'm on a Mac). I am at a complete loss and don't know what to do. If I could only get the computer to recognize the phone I could flash the original google image through Terminal, but alas, I can't. Any ideas? If I can somehow get this phone back up and running I would be eternally grateful. For now, I think I may be SOL. Thanks....

This happened to me, I was not able to solve the issue, even though I could push and pull data to and from the device via ADB. I could still not get past the google logo. I decided to lock the boot loader again and return to the store for a new device.

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] Nexus 7 stuck at Google logo and can't unlock bootloader

Hi all
Interesting issue that I've searched here and Google for and not getting far, my searching skills may not be the best though as I'm fairly new to this.
My Nexus 7 was working fine, put it on the side, came back and it's turned off. Thinking it's flat I charge it and try to boot it with no success. Pressing the power for a while does get it to turn on but it gets as far as the Google logo and stays there.
I've factory reset it in the recovery and nothing
I've tried to flash the stock image from Google but when unlocking the bootloader it just sticks on "yes" forever and nothing happens.
What can I do at this point?
Cheers

Have you heard of Wugfresh Tool kit ? (aka Nexus Tool Kit) It is in the development section or you can google it. It is quite famous.
It will do anything actually from drivers to repair a device stuck on google logo. Just make sure you select the correct option.
You will need unlocked bootloader to flash stock images. And to do either of those, you will need drivers!
Install drivers and use it to recover your device. If you still have trouble, quote me back and I will help you to my best of ability.
Look into the forum before posting your questions. There are so many similar problems and you can easily find a solution by reading their questions and their possible solution.
Good Luck!

I'm having issues with my nexus 7 (2013). It will not boot up,it's stuck on Google logo. I am able to put in fastboot mode. I'd like to do a hard reset/wipe but I cannot enter recovery mode; it just goes to the Google logo and doesn't show me the recovery menu. I thought I could try doing it through adb but bootloader is locked. Downloaded WugFresh toolkit but it requires correct build number, which I do not know. I tried different ones but everything fails. AND USB debugging is not enabled, but I cannot do it through my tablet because it won't pass bootloop. I haven't been able to enable it remotely. So, any help with getting this tablet up and awake?! It's not rooted BTW, its running stock 6.0 marshmallow

Interesting, and troubling for you, I'm sure.
-- What do you mean, in fastboot it doesn't show you the recovery menu? If you are into (more properly) bootloader mode, the Recovery option has to be there. Do you mean you just can't select it, or that it won't work when you do select it?
-- Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img".
-- Have you tried unlocking the bootloader via fastboot? Is it possible OEM Unlock is already/still enabled somehow?
-- Also.... Wug's NRT doesn't need the correct verion/build. The last option in the drop-down menu on the NRT is this: << Android *.*.* - Any Build >>
HTH

-- When i go into bootloader/fastboot mode, the option is there for recovery mode along with 'start' and 'power off',etc.. However, when I select it,it just hangs on Google logo and never shows me the Android man and recovery options.
-- Sorry, not sure what you mean by this: "Using fastboot, you might be able to boot into custom recovery without flashing it. (e.g. "fastboot boot twrp.img", not "fastboot flash recovery twrp.img"."
I may need some instructions on how to do this please.
-- I have tried unlocking bootloader via WugFresh and Nexus toolkit and via adb but it hangs on erasing user data and also hangs on 'unlock bootloader's screen (left it for over 12 hrs). I doubt anything is unlocked.
--Yes, I tried the "any build" option and nothing works.
Thank you
I'm open to any suggestions.

Ah, right. I didn't read closely, and didn't realize you might not have used fastboot tools... and please, I'm no expert, so if I'm saying somthing inaccurate, I very much hope someone will correct me.
I'm never sure how much a poster knows, so I'm not sure if you meant you don't know fastboot commands at all, or just the specific ones I mentioned .. fastboot commands are like ADB commands, but run in the bootloader environment. We know you have fastboot commands installed and fastboot drivers installed on your computer because you have adb installed - which includes fastboot, and you said WugFresh's tool was able to run, which means you also have the right fastboot drivers (the NRT uses the same fastboot commands).
fastboot can be used to flash/install custom recovery packages, among a whole lot of other things. So what I mentioned in that command was a possible way to maybe get into a custom recovery if you have to do things like wipes or whatever, even if you can't actually fully install the custom recovery. You might need to do this stuff, if you can't unlock your bootloader and flash the whole official Google Factory Image from their website (which is what I'd try - simple instructions are right there, too).
Flashing the full factory image will wipe your device, of course, but there are simple ways around that, which you can find on this very forum. Good luck.
Let us know how you get on.

i need help

Have you tried the Nexus Root Toolkit by Wugfresh?

Nexus Root Toolkit has a Soft-Bricked/Bootloop mode this may be what you are looking for.

i did its stuck on google screen with start button showing it seems theres not backup on it or recovery all i can do is get google screen with either start, recovery mode, restart bootloader, and power off showing i cant seem to get it to flash anything on wug . could it be i have windows 10 on my computer now

I have only had my Nexus for a couple weeks now so more experienced users please feel free to jump in. Sometimes is best to just flash a fresh factory image and start over.
Prerequisites - Have ADB and Fastboot installed and configured
- extract the factory image that's linked
- Reboot into your bootloader and unlock it if you haven't already done so
- while in booltloader flash the factory image using fastboot by running the flash-all script
- tablet will reboot and you should be back to stock
