can't understand you?

It's easy.
Dial *#272*imei#
From the menu select XSA.
There is a drawback if you change CSC with out changing PDA. You won't OTA updates anymore.
To effectively change CSC with out loosing OTA updates, you have to manually download the XSA firmware with PDA, CSC, Modem and Bootloader and must be flashed together.
