take out your battery and google your product code then you'll know which country it is from, if it's APAC1-good cause you can update in any country within the Asia Pacific when there is any update, If APAC1 code with certain country-then no good, you can only update in that country only even though there is an update in the oversea country that you are in.(let say your APAC1 code is Thailand code and you are in Malaysia, there is an firmware update in Malaysia and if you try to update you can't do it.)
