Nâng cấp Firmware cho máy MP3 làm sao ???

Hiện đang có cái MP của Creative MuVo TX FM 512mb dùng firmware mặc định cài trong máy nhưng hình như bị lỗi ko nhận được wá 136 file (cỡ đó) nên giờ muốn nâng cấp lên Firmware thì phải làm sao ??? Đã lên website down firmware mới nhất là 1.19 rồi, kèm luôn cái Creative Mass Storage Drivers 1.07 rồi nhưng ko có hướng dẫn cách nâng cấp.
