Restore from SD card - How To


Recommended Posts



My S3 stopped booting past the Samsung logo.


I entered the System recovery mode, and tried to wipe data\factory reset onlly to see the following message


E: Failed to mount /efs (Invalid Argument)


After doing some googling, I tried to recover\restore using KIES then ODIN, but my PC does not pick up the phone at all


I am not trying to find how I can restore the OS form an SD card, could someone provide me with the steps?

Googling has not delivered any definitive results

 You can very often recover deleted pictures from a camera memory card or USB Memory stick. However, to increase the chances of being able to recover pictures after they have been deleted you must not save any new photos, files or data to it. 

When you delete pictures (or any files) from a memory card or USB memory device the data itself isn't deleted, just the file system pointers that says where the data for those files is located. The area where the deleted picture data was stored is also now marked as free space so it is available to the system for any new files to be written there instead. 

If and when that happens, then it is too late to recover your deleted pictures so it is very, very important that new pictures or files aren't saved to the memory card in the meantime. 

One of the easiest ways to see if your deleted pictures can be recovered is to try some photo recovery software.
