    sir, so this is not applicable to my device?, because it is not rooted anymore after i flashing cm10.1,

      Don’t understand what you mean. First of all CM10.1 won’t void your root. Next, root is not required if you want to flash original firmware such as this one. You will lose root after you flash official firmware.
