Is Ishi san here?Or some one who could help.... I am using a HK model which firmware is updated to 3.0.0.C171f. I feel it inconvenient for me as I need it to display kanji when I browse the lyrics. I realized 3.0.0.c171f (english version) didnt support kanji lyrics. So I 'd rather reflesh the firmware to 3.0.0.C171J(JP version) I dont know the feasibility cos this is not an upgrade,isnt it? Is it practicable? Any problem if i do change the firmware from 3.0.0.C171f to 3.0.0.C171J? Please help me !!
