I think I got myself a Maguro Galaxy Nexus (on ATOM ROM, Android 4.2.2) with a corrupted /data partition.
(Not 100% sure though, so if you think I'm wrong, please tell me)
I can't wipe the /data partition in CWM, nor perform a partial restore for data from nandroid backup. When I try that, CMW crashes and my phone reboots.
I can however still boot the phone normally. Everything else works, just can't do a factory reset in CWM, which I want to do to flash a new ROM.
Any ideas how I can solve this? I'm alright if I loose my data, I got backup. Would like to avoid erasing the virtual sdcard though (takes ages to copy).

Try using what command? I can flash roms n gapps no problem, but I can't do factory reset. Is there a command for factory reset in fastboot?
P.S. We are almost neighbours, Schiedamer hier.
*EDIT*
Lol, feel a bit stupid now. I didn't know there was the fastboot command "erase". I erase userdata using fastboot, however, now I got a whole new problem... It got rid of the whole folder, not just the contents. Now there is no data folder. And I forgot that the virtual sdcard is also inside the data folder... Now I got no data at all, nothing to flash...
I'll try to find out what to do, but if anyone reads this soon, perhaps you can help me.
*EDIT2*
Alright, I tried something I've wanted to try a long time now - I connected my USB memory stick (OTG mode) while in CWM. It worked wonders. I have all my zip files (ROM,Gapps,Kernels) on it, so I flashed from there.
EVERYTHING WORKS NOW.
Though my sdcard data is gone, but luckily I backed it up this morning.
P.S. For those of you who don't know, I found out you can restore nandroid from, and backup to the USB memory. I think I won't even put my nandroid and zip files on my phone anymore. I'll keep it on my usb memory.

I am running incredibly reengineered rom. My sdcard caras and I had to reboot with a new sdcard. I was able to back up recovery or any other the other files the sdcard was toast. Now my phone boots but force close rom manager, titanium back up, etc and although my phone is rooted and I can still boot into recovery I dont what todo to get the rom working again. Do I find a recovery image and flash it or do I flash the rom again?
Might want to try booting onto recovery.....wipe/factory reset, wipe cache, and dalvix cache and then reboot and let me know what happens

Thank you! That's exactly what I did. I booted into recovery, did a back up just in case something went horribly wrong. Then I did a wipe/factory reset, empty dalvix cache and viola. My phone was still rooted and I reinstalled Titanium backup and was able to put all my apps back on the phone. Afterward I did a back up of all my stuff, then I flashed the recovery and backed up the ROM. Everything is working better than normal. Thanks!
Good glad I could help......

Periodic SD to PC backup
As you've learned, a periodic backup of SD to PC is a good practice.
Same thing has happened to me, been backing up SD to PC approx. monthly since then.
so i have been using CM7 RC1 w/ stock kernel for a while now, without any issues. i was reading up and wanted to try the new incredikernel though, for the governor rather than using setcpu/juice defender for increased battery life.
so i did a titanium backup, then in Clockwork did a full backup before i started messing with anything. i then mounted to computer to put the kernel on the SD card. i did this, but was confused where to actually put the .zip file so that CW would see it. SD card or internal memory? i've had this issue before.
anyway, i didn't find the .zip when i booted into recovery, so i went to re-mount to USB to move it over to the other directory, and everything seized up on me. trying to mount USB basically froze my phone. re-booting did not fix, when i try to go into CM settings or try to mount USB same freezing would happen.
OK fine, i just did a nandroid backup so i figured it wasn't a big deal since i haven't actually made any changes yet and so i restored. then it would not boot. got stuck at the CM7 bootloader. ****. so i tried an earlier restore point, from a few months ago. that worked (also CM7-RC1 when i first put it on). i didn't wipe cache/dalvik when i tried the first time, so i wiped now and then tried to restore the most recent backup again. still, no luck.
so i've been living with the older restore trying to get everything how it was before. another note, i had installed a battery meter (RC1 did not come with one), and when trying to flash this, got stuck at the same bootloader screen again. another thing to note is that i have been updating CW to the latest version when it is available, but all versions are 3.xx. the latest i think i went from 3.0.0.5 to 3.0.0.8. just trying to include as much info as possible here...
any ideas? it's frustrating because i haven't actually been installing anything new. at this point i just want my phone the way it was, i.e. getting the latest restore point to work. it won't, but older restore versions will work. did CW mess up the backup, is it corrupt? is this a CM7 issue or CW? help please!
if this is in the wrong forum, apologies, it wouldn't let me post in the dev thread due to lack of posts.
Did you do a complete wipe before trying to restore your backups? In recovery, wipe data/factory reset, wipe cache, wipe dalvik cache, format boot, system, data and cache.

i did not do that before. i just tried though, and same result. stuck in CM7 boot loop.
wtf happened to my backup!
That happened to me once. Try this. Save everything on your sd card to your computer. Reformat card. Then put just the nandroid back on card. It might help.
Yeah sounds like it may be an issue with the SD card or your backup..

I just successfully rooted my device w/Odin, then decided I wanted to start fresh. I used CWR to wipe my partitions, including the System partition. I take it that was incredibly stupid? I guess I'm so used to having a full .zip ROM package to flash with my old phones that I didn't stop to think about what I was doing.
Now I'm permanently stuck at the T-Mobile splashscreen. The progress bar fills, but the phone boots no further. Is there any existing way to restore the system partition to stock? I still have access to CWR and can still flash with Odin. I do see that there are .img dumps of the system partition; can I do anything with these? Thank you!
Have u tried to Odin back to stock?

Do you mean by flashing the ~10MB SGH-T989-Stock-UVKID tar file? If so, yes. The file successfully flashes in Odin, but it the phone still doesn't boot.
Is it at all possible that I need to reflash the system partition? I've downloaded a couple >300MB images of System, either as .img or .zip files. Can I do anything with these?
Then I have no idea sorry

Did you happen to make a NANDROID BACKUP prior to your formatting frenzy?
ALWAYS, ALWAYS, ALWAYS...you get the point yet? If someone else hasn't uploaded one, I'll post one when I get home in about 4 hours...
Well, thank you for trying. To reiterate my problem:
I have ClockworkMod Recovery installed and working. While in it I did the following, thinking this would cause the phone to reboot in a "factory fresh", but rooted state:
-wipe data/factory reset
-format /system
-format /emmc
-format /sdcard
-Wipe Dalvik Cache
I then rebooted, and thus cannot boot the phone. The progress bar fills on the Samsung/T-Mobile splashscreen and then just hangs. Could someone confirm for me that I caused this by formatting /system? If so, is there any way to copy the OS back over to the system partition?
Shamwow, that would be amazing. I did a Nandroid backup, then proceeded to format the microsd card on which it was stored. Chalk it up to pure, unadulterated stupidity.
Anyone willing and able to post their Nandroid backup?
Hello,
My Galaxy Nexus went in to a boot loop for some reason on it's own, it's been working fine for the last few months (I'm on AOKP b24) but today during the middle of the day it just rebooted and then went in to a boot loop. No matter what I do, I can't get it to boot up without hard wiping it. I've pulled the battery for a while, charged it up etc but it's still stuck in the boot loop.
I can still get in to CWM, so that's the good news.
The BAD NEWS is that I don't know how pull my Titianium Backup files from the phone. I'm trying to use the Galaxy Nexus Toolkit, but when I go to option 15 to pull the files, it asks me if I'm running a custom ROM. I answer yes and then it asks me for a path. I've tried entering these: /sdcard, /sdcard/, /mnt/sdcard/titaniumbackup, /mnt/sdcard/titaniumbackup/ etc. but no matter what I enter, it gives me an error saying I'm not running an insecure boot image.
How can I pull down my nandroid backups from the phone so that I can wipe it and then get my data back? Please help..
have you tried clearing the cache partition and delvik cache? lots of bootloops can be fixed by just doing this.
if you have a nandroid backup theres no need to wipe anything before doing the restore.
Nandroid's won't restore? The correct path is: /sdcard/TitaniumBackup/ but if the toolkit is giving you no love I'd try it via adb.
adb pull /sdcard/TitaniumBackup/
For nandroids: adb pull /sdcard/clockworkmod/backup/
BUT
If you do a wipe data/factory reset your backup folders aren't lost, so a completely fresh ROM install won't affect your existing b/u's as long as you don't format your sd card.

Yep, tried wiping cache and dalvik a few times, no dice. I also tried a nandroid restore from CWM but it errors out and doesn't restore..

Thank you. I managed to get the files pulled, just had to manually kill adb and restart it and then I could pull the files.
Now I have also done a factory reset through CWM and the flashed the same ROM again, it's still in a boot loop!!
I'm at a complete loss.. what else can I try?
Could a part of the internal memory be corrupted or something like that?
was the phone a yakju build? if so you can use fastboot or the toolkit to flash them, this will flash the stock bootloader, recovery, kernel and system image.

Thanks, that's exactly what I just did and it worked. No more bootloop! Phone booted up and I'm now in process of flashing my old rom and then hopefully restoring the nandroid.
I have no idea what caused all this after months of stable operation, but at least the phone is alive now..
Thanks all!

Install the Galaxy nexus Toolkit (search for this on xda), then get it connected to your phone by following instructions in the tool.
Then select the option to pull files and give it the right path, which should be \sdcard\DCIM\Camera\.
This will pull the files to your computer where the Toolkit is installed.
Hope this helps!

For some reason while reading about toolkit last night I gathered that it wouldn't work.. Perhaps I was wrong so this morning went ahead and did a reset to factory :-/
Thanks for the suggestions - I will definitely look into it if it occurs again. If it does, I will be posting a video on YouTube of burning it down
Hi,
I am currently running AOKP build 31... I know there are many more recent builds but I was happy with this one.
I decided to try JB and was trying to wipe the device and I'm facing something strange:
- I tried to wipe the phone (data, cache, even data/factory reset) from the recovery menu and it has no effects at all...
- the first couple of attempts I did not notice that the wipe was not happening and when I tried to find the JB zip file on the phone from the recovery menu, it said "can't mount /sdcard"...
- I tried to trigger the factory reset from the settings menu on the phone and the phone comes back exactly as if I had done a simple reboot...
I'm a bit lost... Am I missing something obvious? I did search and was not able to find something that would look like what I'm facing.
Thanks for your help,

Maybe try Super Wipe Lite? Idk... it might be of use. Just flash it and it should wipe your device (except SD card of course).
Did you wipe system?

Would be interested in testing this, but I seem to have no way to flash anything since when I'm in the recovery menus, when it tries to access the /data or /sdcard folders, it does not find it...
I think I'll have to find a way to get recovery to "see" /data and /sdcard to be able to fix that.
I found a "format system" entry... Just did it... Not too sure where this is going to take me...
I would reflash recovery if I were you. You can do it from fastboot mode using the gnex toolkit

I had tried it earlier today and it did not complete the operation (was blocked at something like "waiting for the device" something).
I have just done it again (after formatting /system) and it worked.
But it still doesn't "see" /sdcard... so I can't load anything...
Now when I enter in fastboot, I see : Fastboot Command Read Error - 21474833647
EDIT - I reflashed Recovery from the toolkit and Fasboot status is now okay... I guess I now need to find an img file and to try to flash it from the toolkit?
I'm stuck here... What would be the next step? I tried to do a Nandroid restore from Gnex Toolkit but when I start it, the main window of the toolkit just vanish and that's it...
Okay, so I used GN Toolkit to reflash entirely the stock config and now I'm installing 4.1. Don't know exactly where things went wrong but I'm now back on tracks, it seems.
Thanks for the help.

Probably because you didn't read the instructions and were in recovery instead of in fastboot.

Yes, that most probably explains the second problem where the phone was not detected.
But i'm not sure it explains the first problem where there was no access to the /data or /sdcard...

CWM says : E:Can't mount /sdcard
Okay, so now I am trying to get back to my previously backed up ROM, after having tested JB...
And I am back to where I was earlier: CWM can't mount /sdcard...
I must be missing something very obvious but I don't know where to start looking.
I have just wiped entirely the phone, thought that this problem would be gone.
Any hint on what the issue could be?
Thanks,
I might be having a related problem, but it wont even let me go back to the stock rom... it errors out when flashing the stock rom but the recovery flashes a zip already on my internal storage..
My problem is that with JB and now clean CM9 RC1 both of them have problems booting and freeze and reboot during the bootup sequence..
