Hey,I find best way to get firmware for your phone ;)

Download SEking (SeKing3.0.3.0_English - SE-NSE Forums when you open that program you will see there window Flash Files,and then there you just need to select and download almost all firmware you want/need!

After you download firmware from there,use GConvert (GConvert - SE-NSE Forums) to convert that firmware,so you can flash them easily in XS++ ;)
