Upgrade my n93i to Euro01 firmware

[Dantotsu]

Hello

I have a N93i-1 phone and I want to change the firmware to 30.03.013 Because I need the spanish language to be available, I already change the product code with NSS from 0515695 to 0532063 (euro01) but when I try to update it with the NSU it keeps telling me that the 06wk15v42.1 is the latest one so theres no update availabe, does any one know what I am doing wrong, or if need to change something else to force the update. I will apreciate your help so much because I hate to write instant messenges without T9
