Romanian CSC codes listed as CNX, COA, HAT, ORO, OXX but ALB doesn't exist according to the thread in stickies.
If you're using the phone in Romania on Orange then stick with an Orange firmware, or you can go for the general OXX, or the latest firmware (netherlands) and change the modem afterward to match your country.
CSC doesn't mean a great deal, other then helping set APN. You can flash any firmware for the i9300 and it will still work, only having the right modem is important.
Suggest you go read the basics in stickies as it sounds like you are struggling, oh and Kies is a useless tool.
