P.S. local service center guy says it's an corrupt EFS issue.
Need help on corrupt EFS issue. I bought Korean variant E-210s. It came with modified ROM for GT-i9300 (i9300ZSALG3). I thought it was the international version and that's why I flashed the JB ROM (update) for GT-i9300 using ODIN. Now, I am stuck on Samsung logo and OS is not loading. I can access the Download mode and Recovery. In Recovery, it shows "unable to mount E:" error when I flash any rom. So, I am stuck here. Need your valuable suggestions on this.
