I can't find 4.2 but there is a Nordic version of 4.1.2 available here - Instructions here simply substitute the firmware for this one here to the one mentioned on that site

Another short Question:
Is it with the same Way possible to install & test Cyanogenmod ?

And reflash to default Sony 4.1.2 ?

Custom roms require an unlocked bootloader - You then enter fastboot mode and flash that way but to enter fastboot mode you need an unlocked bootloader - You could if I'm right flash a custom rom via a recovery like clockwork mod but again you will need an unlocked bootloader - But yes to go back to stock the same method applies as it does to all Xperia devices except you will need the specific .ftf firmware file like you downloaded earlier
