[Q] corrupted /factory mount point & efs partition - Samsung Galaxy Nexus

Hello All;
It looks like my /factory partition has been corrupted on my phone. This contains the efs data (imei and other). I tried copying it from my wife's phone and for some strange reason, the phone does not detect my sim card.
I do not have any nandroid backup. Is there a way to restore the efs partition of my phone ?
Pointers/leads are appreciated. I would be rather grateful if this brick can be brought back.
Thanks
Shyam

Hey man, have you found anything ?
Were you able to restore it somehow at home ?

[Q] Restart during nandroid backup

Hi to all,
i have a problem.
During the backup from cwm recovery 'recovery-clockwork-touch-5.8.3.1-endeavoru' my phone restart every time. So the process fail and i'm unable to finish the backup.
I'm using a custom rom "Revolution HD 5.0".
Any advice?
Thanks in advance,
Sartan
I have the same issue with revolution 5.1.1

Hello,
same issue on my phone. Are there any solutions?
Guys, i fixed the problem.
You have to:
- Save all application with astro/titanium
- Save all the datas from sd card into your computer
- Format the 2 giga internal data partition from your phone
- Format the biggest partition (about 24 giga) from your phone.
- Reboot your phone
- install all your app
- restore data
- NANDROID
For me it worked
I had this problem as well.
The problem is (best guess) kernel oops when accessing certain files on the partition.
In my case, it was one of the files in /data/lost+found/... - whenever it was stat()ed or read the phone would reboot.
Let's hope we're not having a defective flash blocks but just a b0rked filesystem.
The worst part is, that without USB debug in recovery, it can't be repaired, because it can't be unmounted once booted. So there's no hope of ever recovering it without full wipe :/
And in this case, it can't be backed up because recovery doesn't allow selective backup of folders on a partition, and it doesn't just dump the partition image for some reason but tried to reas the files - which reboots the phone.
It probably could be solved by chefs in ROMs or by recovery developers by providing an option to run fsck on the filesystem before it is mounted.

So the problem can be solved only by wiping right?
For me it wasn't a problem, i wiped and then i backup the rom.

[Q] Sd-ext.img not found?

I was restoring my phone and then while it was restoring it said Sd-ext.img not found and then restore complete. I highly doubt that it was a full restore since it only restored one folder which was .android_secure. What do I do now? Factory reset?
See if the phone operates fine with the SD card readable with no issues. If there's something wrong, do a reset.

Can't mount /data through recovery

Title says it all, I've on twrp recovery right now. I tried cwm before since i was having that problem. First time with Samsung any help would be appreciated.
Thanks
Edit: I believe one the phone is encrypted, the data can't be mounted to security purposes.

Same problem
I have the same problem. My device's (Samsung GS III VZW) internal storage is encrypted as well. Does this seem like this could be what's causing this?
I want to make sure that my backups are good that I'm taking with nandroid in CWM 6.0.1.2. If I choose straight up Backup & Restore -> Backup from the menu then I get an error:
Can't mount backup path.
If I choose Backup & Restore -> Backup to external sdcard, then it chugs along for about 30 seconds, then gives this error:
Backing up data...
Can't mount /data!
However, my backups that are put on the External SD Card (extsdcard/clockworkmod/backup/<datedfolder>) only consist of 3 files, boot.img (10mb), recovery.img (10mb) and system.ext4.dup (317kb). This doesn't seem right..
Any thoughts? Does this seem like it could be caused by the device being encrypted ?
Thanks! I'm a real noob and really appreciate the help!

Ya I say definitely stay away from encryption if your gonna flash roms. I've been here before backup what you need and wipe data in recovery. If it doesn't work flash the stock jb rom thatll wipe it.(located here if needed http://www.mediafire.com/?c3cj6udkai1ljhk ). As far as the backups go I believe that's actually the right size. Cwm uses a weird format for its backups now. Granted if data can't be mounted I think those backups are worthless now anyway

[Q] [HELP] - Can anyone post a TWRP backup of their /preload partition please?

Hi,
Wondering if anyone will be able to post a backup of their /preload partition, I appeared to have mashed (wiped) mine
I'm hoping to restore my phone from your backup.
It would be much appreciated as I believe that's why my phone says there's no SIM installed even though there is and the SIM works fine on every other phone I've tried it in.
TIA!
