Default [Q] S3 i9305 boot problem (E: failed to mount / efs (Invalid argument)

following a bad repair of EFS my S3 i9305 dont start and still frozen on samsung logo and when I try a recovery it shows me the message:
wiping data ...
formatting /data...
E: failed to mount /efs (Invalid argument)
formatting /cache...
data wipe complete.

I have no backup of EFS for my phone
I try to flash my phone with several firmware but the problem persists.

In the Samsung Kies application under "Tools" there is "Firmware Upgrade and Initialisation,"

With your device unplugged (it will say not available for this model if its plugged in, don't plug it in until it tells you to when in download mode) select this and run the what it tells you to do,

After this is finished you will have a completely fresh install of the latest officially released firmware (for your original build eg. carrier branded) with original serial number and imei number


This does not work for all but its worth a try, you have nothing to lose

You must have efs backup in order to restore it...
