I've been lurking for quite some time and haven't been able to find a solution for my issue. Here's what happened:
I cracked the screen on my Galaxy Nexus and got an insurance replacement. I then used ClockworkMod Recovery to copy over from my old device to my new device. All was good for about 12 hours when the new device started boot looping with the flashy color animation screen. I figured that might have been something I did, so I tried doing a factory reset and the like with ClockworkMod Recovery and managed to totally mess the phone. After trying to do a factory reset, the phone wouldn't boot up at all anymore -- I just get the dreaded red triangle with exclamation point. I tried formatting all the partitions with ClockworkMod (which was a bad idea). Ever since then, I've been stuck. I've spent several days so far trying to get this thing working. I have to note that Odin and fastboot modes work perfectly fine.
Among things I've tried unsuccessfully:
Flash to stock using Odin
--Odin says everything is fine, when I flash with a stock ROM that I downloaded. Upon reboot, nothing is any better and I still get the red triangle/exclamation point.
--When I try to use the tar files that ClockworkMod generated, Odin crashes immediately.
Push custom ROMs to /sdcard/ using adb while booted into ClockworkMod in hopes of getting the system to boot.
--This never works successfully. Sometimes I get no error but can't find the zip file. Other times I'll get an I/O error, or even a read-only error. The original backup is giving me checksum errors.
Flash factory ROMs using fastboot.
--I always get the red triangle/exclamation point.
Restore and flash with WUG's toolkit.
--Same thing as when I try to use fastboot. It seems that flashing the device goes fine, but the device will still not boot.
After every time I've flashed the device, whether using Odin or fastboot, I've tried doing a factory reset by pressing power+vol up+vol down and then selecting factory reset. This hasn't made any difference.
I'm about to give up on it and send the device back to the nameless insurance company, but I would like to lock the bootloader first. I can't even seem to lock the bootloader! In fastboot, I type the usual 'fastboot oem lock', and the device reports that it is locked, but after rebooting, the device always reverts back to having an unlocked bootloader.
Have I missed anything? Any thoughts? I'm lost.
Fyi, the red exclamation point is the stock recovery screen.
Try following the instructions in the "flash" link in my sig.

As well, issue the following commands when in fastboot:
Fastboot erase system
Fastboot erase userdata <- this will wipe by the way, including/sdcard
Fastboot erase boot
Fastboot erase recovery
Fastboot erase cache
And then flash the images in fastboot.

Thanks a ton for the helpful info -- I hadn't tried flashing userdata and system using that method before, and your write-up was definitely one of the more helpful I've seen.
Unfortunately, it doesn't seem to have helped. I used the factory 4.0.2 mysid/toro image on the link you provided. While flashing, the system seems to work absolutely fine, but it just reboots into recovery at the end.
I followed your instructions twice, including erasing the partitions. Also, after each try, I've tried doing a factory reset from recovery and then rebooting (after trying to boot a couple times), though none of this helped.

If you've flashed the system, userdata and boot images using fastboot, and you are still not able to boot into Android, I can only suspect that you have either a corrupt bootloader or a hardware issue.
And if odin does not work, then unfortunately I would suspect that there is a hardware issue.
This sounds like what happened to my phone as well. Someone else had it happen too. That's 3 nexus's in a week. Mine didn't even last 2 months.
I have a thread about mine and another user posted another thread a day or 2 ago. Mine boots into the system but is not erasable, not writable. Can't lock my boot loader. I've tried odin, adb, everything possible. I wish we could start a lawsuit because Samsung won't help me. I'm in the US and it's a gsm nexus that was purchased before the play store sold it. USA wont accept an international phone and UK Samsung won't take a phone from overseas. Basically they said I'm sh*t outta luck.
Thanks again for the help. I'm going to bite the bullet and just call the insurance company and try to send it back as a defective device. Hopefully they don't rake me over the coals.
I'll post back with an update as to how that goes.
You guys need to learn how to use fastboot and adb commands correctly to restore google's stock images.
Stop realying on toolkits thinking it will help you.
Also learning that the Red Exclamation Android is stock recovery!
Press the Power and Vol Up button will get you the stock recovery menu options to come up!
Not to be mean, BUT I hope the insurance company denies you, you totally screwed up the phone yourself.
I did not screw my phone up myself. My phone was never even rooted. I know very well how to issue adb commands and install images. Learn what you are talking about before you jump onto people or come across as a total di*khead
Alright, replacement phone is on the way. Thanks again for the help. I tend to think it is a hardware issue because of how the issue originally presented itself, but I'm still pretty new to the Android platform. It seemed to me that a watchdog timer was timing out or something similar.
Perhaps this will be the push I needed to start developing Android hardware/software... I'm all about embedded systems and would like to move beyond basic ucontrollers.

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.

So I was attempting to unlock the bootloader using GNex Toolkit, which I now know I never should have done. After supposingly unlocking the bootloader, the Google screen would show up for about 10, then the phone would reboot itself. I decided to let it run its course and see if it would fix itself, but after doing this for about 30 minutes, I figured it wasn't going anywhere. So that's when I (also against my now better judgement) tried to relock/OEM restore using GNex toolkit. Well it wouldn't unlock, and the boot issue still exists. So then I started digging, and found efrant's wonderful guide on restoring my apparently soft-bricked device. However, even this did not fix the issue. I have tried locking the bootloader through fast boot, and while it will say that the bootloader has been locked, upon restart it was still unlocked and still having the boot issues. I even ventured as far as doing a ODIN reboot, but still same issue. I have since tried efrant's again, but still the same issues. I have access to fastboot and ODIN, and recovery, although I have not messed around there too much as I have not been able to find any information about that. At this point, I am all out of ideas on what to do. Just some last bits of info.
I was doing this all on a very freshly installed Jelly Bean update. This particular phone has never been rooted or unlocked. I don't really care about having it rooted or unlocked at this point, I just want a working phone.
Please feel free to make any remarks toward my past actions of using toolkits, as I have now since found the light, and any additional advice would greatly be appreciated.

The difficult part now is to understand where did the toolkit fail.
If you ran through the process manually again, and it still bootloops..Have you tried erasing first, then reflashing?
Code:
fastboot erase system
fastboot erase boot
fastboot erase userdata
fastboot erase recovery
also, while it's bootlooping, is logcat already running? That could allow some more insight on what's happening.

Ok. I foolishly enabled encryption on my i711 and after putting in the password, the volumes unlock and the system starts. The problem is that if the screen goes off for any reason, the phone reboots. Tried all sorts of things to correct and decided I no longer wanted the phone encrypted. There is no way back. Ok, so I thought I could do a factory reset... No dice. The phone reboots and all is still encrypted and there.
Next I tried clockworkmod but couldn't do ANYTHING there because the encrypted volumes aren't mountable. I couldn't factory reset, install a new rom, etc.
Next I went to ODIN and tried to repartition. No luck there either. I flashed clockworkmod again for good measure and even tried Nand Erase All.
After this I booted into the phone and tried to repartition... Now I have a phone that displays the lovely CM10 boot screen but never gets passed that. I can still get into recovery.
Any thoughts on how to undo the encryption and reflash a rom?

I have some very bad news for you.... Encryption is a one way street. Once encrypted the only way back is to flash stock via fastboot.
I can't even start to explain how to use fastboot as I have never been in a situation where I have needed it.
recoveries lose all access on encrypted devices so this is the only way.
Here is some links to get you started... Please do research before you begin the process and make sure you've obtained the appropriate files. I will take no responsibility for bricking your device.

Hey guys,
Long time lurker, ROM user since the Galaxy S days.
Weird, intractable bootloop problem here. Gets to boot animation sometimes gets to the "upgrading android" screen, then bootloops in a few seconds after upgrading a few apps. Usually bootloops during the boot animation (doesn't matter what ROM or Stock ROM I try). Ocassionally gets to my "SIM PIN" screen, then reboots before I have a chance to enter anything.
Normal State have Cyanogenmod and Franco Kernel running buttery smooth. (CM10.1M3 Snapshot + Franco 376 when problem started)
Problem Started When I tried to update CM to the new RC1 from the Cyanogenmod upgrade button in "settings". I had SuperSU installed overtop the built-in superuser. Everything was working fine.
What I have tried:
Have latest CWM: Have flashed, reflashed, wiped and re-wiped everything imaginable through CWM. All Caches, system sdcard, you name it, if it's an option in CWM I have tried formatting or wiping it and reflashing a ROM.
ROMs I have tried - CM10.1M3 Snapshot, CM10.1RC1 CM10.1RC2, ParanoidAndroid 3.5+ (Latest), Bigxie Maguro Latest.
Finally I got fed up and decided to go back to STOCK, unrooted, unlocked using fastboot.
I did:
> fastboot erase boot
> fastboot erase cache
> fastboot erase recovery
> fastboot erase system
> fastboot erase userdata
> fastboot flash bootloader magurobootloader.img
> fastboot reboot-bootloader
> fastboot flash radio radioxxlj1.img
> fastboot reboot-bootloader
> fastboot -w update image-maguro-jdq39.zip
And after booting back into the STOCK google recovery (man I haven't seen that screen in AGES) and resetting factory clearing cache. Low and behold -
STILL BOOT LOOPS!!!! What the hell!?!
I'm at my wits end. Any suggestions would be great. What am I forgetting here?! I am absolutely desperate.
What is in the update image and where did you get it? I'd flash everything manually, skip the update command.

Ok good idea, I'll try. The update image was the stock image from google (can't post link - low post count) I just didn't remember the filenames when I was making the original post - but they are the official STOCK images - for the radio, the bootloader and the ROM.

So decided to try TWRP just to see...well I dunno.
Interstingly enough when I got to hit "reboot" in TWRP it says "OS not installed!!" which is weird because I basically flashed the stock everything 4.2.2 (bootloader recovery, system, boot, everything) from fastboot. Then JUST flashed the TWRP recovery.
I really don't know what to make of this. I just tried keeping the battery out for like 2 minutes, then going back into fastboot and manually flashing:
bootloader
boot
radio
recovery
system
userdata
relocked bootloader
of the STOCK google maguro 4.2.2 (MD5 sum is good. It checked out)
And I still get a continuous reboot loop that doesn't even get past the "X" animation screen. Very ocassionally (1/10) it does get past that screen and I get to the screen where you choose your language, but right when I choose my language, the phone reboots and then continues the loop.
Honestly...Unless someone has another idea, I think I'm going to get another phone tomorrow and pray I'm under warranty. I hate to do it, because I've never had to do that before through all my flashing/ROM adventures...but I don't know what else to do. I've been using sideload for everything (except of course the fastboot flashing back to stock), but I doubt that has anything to do with it...I dunno crap.
anyone have any words of advice?
One thing I thought i might work was redoing the partition table in Odin. So I tried this method:
http://forum.xda-developers.com/showthread.php?t=2065470 (Thanks to Samersh72)
ODIN worked perfectly, download mode worked well, installed fine, and...
still bootloops!
Sometimes gets to "updating android" does a few apps, then bootloops. Once got to the screen where I select language, and before I could select anything - bootloop!
Do you guys think this is hardware? Right now I've installed stock 4.2.2 through ODIN and locked the bootloader in anticipation of returning the phone...

I looked into the OMAP flash method - that's some hardcore stuff. It looks like it's more for phones that can't access recovery, or hard seemingly bootbricked. I can actually do all of those things with my phone - I can write a new recovery no problem, I have fastboot access (Works well), I can even seemingly install ROMs - for instance the cyanogenmod boot animation plays fine - but everything boot loops.
I'm a bit worried to try OMAP Flash because it seems from the thread that some people are having their IMEI numbers erased or set to generic and I don't want that to happen since I'm actually still under warranty right now...
Do you think it's worth it to try?

Yeah you're right. OK done.
While I agree that the safest route is to return the device to warranty, omapflash is a tool which communicates with omap chip before even fastboot/bootloader is installed.
Have you tried viewing logcat/dmesg while device is booting to see why and/or its bootlooping?

I can't seem to get at logcat from this state. even if I try adb -d logcat or something similar it doesn't work. It doesn't pick up the log from the boot. Is it because USB debugging is disabled by default on the stock OS?

Yes, but There's a build.prop property that enables ADB debugging.. Since you have access to a custom recovery, you can mount /system rw and make your changes there.

Similar issue
Hey guys,
I am having a similar issue with my Nexus. It is running Phandroid 3 and one day just locked up, rebooted, and shortly after reboot (15-30 sec. after the OS loads) it freezes. I can still boot into CWM recovery and into fastboot mode, and have tried to flash it with the stock rom and bootloader. I also tried an OMAP flash, but that did not change anything as well. The odd thing is that when I try to flash a new rom (I have tried stock and other custom roms) it flashes as if everything is fine, but when I reboot it still has the phandroid rom on it. Another odd note is that when phandroid boots it notifies me that I have an incoming text message, but I removed the SIM card over a month ago. I have been struggling with this and would love any thoughts or opinions anyone has to offer. Thanks a lot!

I dont know if you already did but try to wipe /system also and then flash a ROM.

EDIT: SOLVED. After some hours at work I was able to boot back to the bootloader and flash the images individually.
TL;DR at the bottom.
Hi, I've been rooting and ROMming for a while now, and last night I made a mistake that set forth a chain of depressing events. I have a N7 2013 LTE, and was running AOKP up until last night. I wanted to flash the 9001 L preview, despite having no access to data. Simple right? Wrong, you forget to realize I'm a tired idiot last night. I downloaded the zip no problem, rebooted to TWRP and commenced my advanced wipe. Some how, I mistakenly checked off "wipe internal storage" during the process. So I go back to the Install screen, and my heart sinks. F***. At this point I decide to let it lie in recovery until tomorrow (today) and keep it charged.
Fast forward to this morning, I'm at the office. My device is charged and waiting in recovery. I decide I'm just going to flash the factory image to stock 4.4 and start with a clean slate, wiping all (even though it's wiped). Reason for factory image and not just adb push the ROM is that I'm having a seemingly-unsolvable issue of incorrect storage. It tells me my 32gb device only has 11.6 gb total storage. This has persisted through multiple clean-wiped installs of various ROMs, but I don't know if it started out like that when I bought it, since I didn't think to check before unlocking and putting a ROM on it.
So I get the SDK and images on my work PC, and commence flash-all.bat. Working great until it gets to system.img, then it fails. Try again twice, same thing. Open the image zip and extract the files, then try to flash one by one, now it's saying the commands are invalid (fastboot flash system system.img, etc). So I wonder, because sometimes these devices are wonky in ADB, maybe it installed and just said it failed? F*** it, I'll try to boot. Google logo for an hour. Ok, cool, I'll go back to the bootloader. NOPE. The device either won't power on at all, or it will get stuck at the splash screen and hang there. Any idea where to begin to fix this?
TL;DR: No OS on phone, failed flashing system.img in flash-all.bat, now device won't boot to bootloader or (missing) OS. Any ideas?
