Is it possible that you try to backup to the micro sd card?
If so, try to backup to internal storage.

If you check you backup directory, you'll notice it doesn't have the file "nandroid.md5".
In order to restore your backup, you can create this file manually.
You can do this throught Terminal Emulator.
Code:
cd /sdcard/clockworkmod/backup/(name of backup directory)
md5sum *img >nandroid.md5
This will create the file and you should be able to restore the backup in CWM.

error backing up image /sdcard/.android_secure

Every time I tried a nandroid backup , always come up with error while backing up image of
/sdcard/.android_secure
Can some one help to solve it? Now I can't do a nandroid backup from recovery.
The file (.android_secure) also can't be delete or change the permission.
TIA.

[Q] CWM, error restoring /data

Hi all !
I had OmniRom installed, and after trying to go back to my stock ROM via a CWM backup I had, I cannot restore backups from my external SD card anymore.
Whenever I try to restore a backup (either a newly made one or an old one), I have "error while restoring /data". The WM lock says "can't partition non mmcblk devide /devices/platform/msm_sdcc.3/mmc_host/mmc1".
Backing up to the internal card and then restoring works.
I tried to move a backup from the external card to the internal card and then restoring, but it did not work (same error).
Any idea where this might come from ?
How can I solve this ?
Thanks !

Answering my own question : after reflashing boot.img from FXP250, restoring my backup worked ! I thought it was the one I had restored in the first place, but obviously I was wrong !

Z1 Backup Restoring Problem

Hello guys , i have a problem with backup restoration on my z1. I made a few days ago a full backup on my ext sd card (everything went well) and now when i try to restore it the recovery only restores a part of that backup . The backup is 3.8gb but it only restores about 3 gb and at the end i get this error "volume not found skipping restore of sd-ext error" , the phone boots up but the launcher and a lot off apps are missing . I tried to copy the backup folder by phone and pc to the internal sd card of the phone but i can't because i get an error. how i can restore the backup and what can be the problem? My bl is locked and i used xzDual recovery 2.8.21 and 2.8.23 but i get the same error when restoring. I don't have another sd card to test this. Any help is good.
Error: volume not found skipping restore of sd-ext error
Have you tried mounting the drive that gives the error manually before starting restoring?

Twrp restore error

I am using TWRP 3.0.2-7 which was working fine until yesterday i got this "extracttarfork() error:255" while restoring a backup. I have restored that backup many times before too and didnt tamper with it in any way.
Now i have 5 huge backups on my sd card, none of which can be restored properly, i am saying properly because that error only shows up when the data partition almost finishes restoring. I can restore system and boot without any problem(basically any partition other than data)
According to the information i gathered from net, this error should occur when i am running low on storage which isnt the case. So totally confused
The log is in the zip
Any help will be appreciated, thanks
