[Q] Bricked Galaxy Nexus (stuck at JB boot animation)

I have a Galaxy Nexus (Verizon) which I just rooted for the first time. I used fastboot to unlock it, and installed clockworkmod and superuser.
I then downloaded the Vicious Jelly Bean V3 ROM to my phone and flashed it (from the Downloads folder in my SD card, not from the root. I didn't realize it had to be in the root directory).
Now whenever I start my phone, I see the Google logo, then the new Jelly Bean "x" boot animation, but then it restarts itself back to the Google logo after about 30 seconds, and continues this way in an infinite loop - the phone won't boot up.
I can access the bootloader (by holding down the volume keys and power button) but I can't, say, flash back to stock ICS, because I can't transfer files to the my phone's SD card until my phone has fully booted up.
I tried wiping the cache partition and doing a factory reset, but the problem persists. What should I do?

First, make sure you're flashing a Verizon ROM, and if you are, I would suggest doing a format of your /system, /data, and /cache. Then install the ROM again from CWM. That should fix any errors you may have.

How can I install a ROM from CWM without my phone booting up? I've tried formatting /data, and /cache, but I'm still stuck on the boot animation. Unfortunately I don't have a backup.
How do you format /system?

In CWM I believe it's under Mounts and Storage.
EDIT: I use TWRP recovery, so I'm just going off of memory here.
You can still put any zip file on your SD without booting your phone up fully, you'll need to use adb commands to do it.
You'll need to open a command prompt window, change directory (cd) to where you keep your SDK folder (eg. cd sdk/platform-tools), put the ROM zip file in your SDK/platform-tools folder to make it easy, and then under the CWM menu Mounts and Storage select "mount /data" (it may already be mounted).
Then in the command prompt window, type: adb push Example.zip /data/media/
That'll push the ROM zip file to the root of your sd card. Don't enter Example.zip, type the name of the actual ROM zip file, I just used Example.zip as the example. See my screen shot of the commands.

stuck in recovery now what?

I updated clockworkmod recovery through rom manager. Rom manager said the install was successful. So then I boot into the recovery to flash the cyanogenmod 10 preview build. I do all my wipes data, cash, exe. Then I go to install the rom and I realize now with the new recovery I can’t install/restore anything from /extsdcard (external storage). It only has the option to install/restore from /sdcard (internal storeage) which would be fine except all my roms/backups are on my micro sdcard (external storage). I have already wiped everything so now I can’t boot my phone to fix it. Is there a way to install the old recovery after I have wiped everything. I was thinking about using Odin to flash the old recovery in download mode again (like I did when rooting) but I am not sure if this is ok to do. I tried mounting the internal storage to my pc to copy the files I need from my computer to my phone. When I plugged it in the box in the bottom right popped up and said installing drivers and they were successful but when I try mounting (anything) the computer does not recognize it. So I can’t transfer the files. Would someone who knows more than me give some advice please?

While youre in recovery, can you mount through the mounts and storage option? Im not on the recovery you are talking about but if you can mount it you can throw the rom on that way. If you cant do that you should be able to just boot up the rom thats currently on it and mount it that way. Just because you wiped everything doesnt mean that it wont boot up, it just cleared all of the data. It should load up with your previous rom.

Thank you very much. It gave me more insight on what was going on. I have my phone back up and working. I was able to flash the old recovery with odin and i hope this information will help someone else in future as well.

TWRP Restore Failed ATT GS3

Flashed the latest stable Carbon rom yesterday and decided it wasn't for me so this morning I rebooted to TWRP and tried to run restore. The restore failed and the only error i see in the console is
Code:
E: error opening '/data/lost+found'
I went ahead and did the standard wipe (which also gave the same error, though it did not say failed) and rebooted, assuming it would just throw me back into carbon, but it got stuck in sort of a slow boot loop. I finally got back into recovery and now I'm at a bit of a loss. I saw only 2 suggestions, one being wipe /data and the other to flash back to stock with Odin. I'm not against wiping /data if someone could could either confirm that it would work or tell me if it's possible to backup some stuff from /data to my external sdcard or pc.
any advice would be appreciated, thanks
also sorry if this is the wrong place to post, I didn't see where else it would fit, says I can't post in the GS3 troubleshooting area.
ATT Galaxy S3
TWRP v2.6.0.0

fixed
Ok, I'm up and running again. I ended up formatting /data through twrp after I found out i could copy files over to external sd through its file manager.
so in case someone else runs into this:
assumes you have a twrp backup on the external sd
1. move important files with twrp's file manager to sd card
2. format /data
3. reboot recovery
3. standard wipe
4. restore backup from external
5. reboot system and cross fingers

[Q] I've unmounted and reset and am now stuck. Help?

I've already looked through previous posts and there seems to be no avail.
From 4.1.2. stock build, UVDMD5, (I'm assuming, that's when I bought it)
I tried to flash 4.4 ROMS onto it, Both Gummy and Beanstalk with their respective Gapps.
It wouldn't work and I wiped and reset and odin'd in the original firmware UVDMD5, so it successfully led to the beginning phone setup ONCE.
Then, from stock, I figured why not root and flash the ROMS once more? and this time, the galaxy would not have it.
I odin'd myself after the roms failed once more, but now..
Now the phone is stuck at the SAMSUNG loading boot screen.
Everytime I odin in the UVDMD5 setup, it says it's successful but constantly stuck at the boot screen.
I can get myself into recovery but no options are available to me.
If I try to progress forward, the roms will not work and I realized what might've done me in.
Once the roms in the very first trials wouldn't work, I messed with the mounting to see if it would change anything(HUGE mistake I now realize)
I think I unmounted /data and /system and pretty much everything!!!
I'm in the stock recovery so I could pull .zips from the external SD and I've tried to put in Cyanogenmod Recovery so I could get to the mounting options,
but now everytime it says that signature verification failed.
Tl;dr: I'm an idiot and unmounted everything and now it's stuck at boot screen and odin doesn't work. PLS HELP!
ps: ignore the ageold signature

First flash the very latest Recovery with ODIN. You will need to put the phone in download mode to do that. Next, flash Root66 version of UVDMD5 via odin and then flash Rom of your choice via Recovery.

I've taken the root66 and finished odin'ing it in, but no success. It's still stuck on the SAMSUNG screen.
When I boot up to (stock) recovery, the first red messages that appear is
E:failed to mount /data
can't mount '/data' (invalid argument)
and when I go into >apply update from external storage and try to apply cyanogen latest recovery,
all it gives me is E:failed to verify whole-file storage.
There is no /data, what do I do?

Please flash CWM Recovery via Odin.

First of all, thanks for sticking with me for this long.
I successfully installed Clockwork with odin and I thought this would be the end, but
It successfully mounted /system and /external_sd but,
Error mounting /data!
Error mounting /sdcard!
I don't know what to do from here. Is there a simple fix?

Did you flash latest version of CWM ? If yes then try Factory Reset in the Recovery.

I did factory reset it:
. . wiping data . .
formatting /data . . .
Error mounting /data!
Skipping format . . .
Formatting /cache
Formatting /sd-ext
Formatting /sdcard/ .android_secure
Error mounting /sdcard/ .android_secure!
Skipping format . . .
Data Wipe Complete.
Is what shows up and still /data and /sdcard cannot be mounted. Anything else? I'm desperate.

Part 2: I tried moving past all that and tried to run the ROMS, but it goes on to tell me:
This package is for "d2tmo" devices; this is a "d2vzw"
what does that mean?

Can you manually mount SD Card in the Recovery ?
I'd not try any roms until this issue is resolved.

What do you mean by manually?
The external sd card can be mounted, I'm pretty sure it means that the internal sd can't be mounted.
How would I mount internal in recovery? the options says it can't mount /data and /sdcard

Try TWRP Recovery.

SM-T210R can't mount /system

Okay so today I tried to flash Inspirekat v2.1 rom on my galaxy tab 3 via latest TWRP, and after I wipe system, data, dalvik cache and cache I reboot into the system and I can't get passed the samsung galaxy tab 3 splash screen after some time I found out that the problem is the unability to mount the /system file, then I tried CWM and still the same thing.
Unfortunately I didn't make a backup because I didn't have any precious data there so I just thought I would skip that, I've also tried formatting all data on internal storage but with no avail...could anyone light up a candle for me?

If you wiped "system" after you flashed, then you no longer have a rom installed. Re-flash the rom.

Sorry I messed it up a bit in my previous post, I didn't wipe system "after" I flash but before I flashed
Every time I try to flash it just takes a minute then I reboot into the system; same thing happens then I get back into recovery to see that the /system is unmounted and can't be mounted back also when I try "repair partition" it shows that only 54mb of /system partition is used and around 1300mb is free, any insight on that?
Some errors about not being able to read storage file context and can't find path to /sdcard also appear sometimes on the log window or however it's called at the top right.

TWRP does have some issues mounting system sometimes.
Once you boot into recovery, choose the reboot recovery option and try the flash sgain.
