I have a Samsung S3 GT-i9300 which has an error on booting up. It goes through the Samsung splash screen then displays the following:

Device Memory Damaged

The data partition has been corrupted. You need to reset your device to factory defaults. This will erase all your data.

I really don't want to delete the data and am looking to recover the media from the device. I'm not bothered about getting the phone working again really.

I can boot into download (ODIN) mode, but this doesnt really assist (or does it?). I can also boot into recovery mode but I get the following errors also:

E:failed to mount /data (Invalid argument) 
can't mount '/data'(Invalid argument) 
E:failed to mount /data (Invalid argument) 
E:Can't mount /data/log/recovery_log.txt

The device shows in Nautilus on my Ubuntu system but fails to mount. I can select the option to 'Apply update from ADB' and running adb devices shows as:

$ ./adb devices 
List of devices attached 
4df74280146d3071    sideload

Is this of any use to me? Is there a way I can get into the storage to salvage what's there. Can I load a custom rom without deleting everything, or if I do delete everything is there a way to recover the deleted files?

You could get the same version of your operating system as flashable zip-file for the recovery mode and flash it, or use Odin to flash a kdz-file of it. If the files you'd like to get back are not in the system folder (like music or images) there is a chance they will still be there with the flashed system. Just don't do any formatting prior to flashing!


What worked for me was to restart the phone and the damaged message went away!

  • Restart won't help much if the device isn't booting up, as the OP indicates. He's obviously tried that already.
