thomas_hang0001 , to flash these dumps into your player, you'll need to use MP3 Utilities available in the downloads section here

Any version would work, but if one does not flash properly, uninstall and try another version.
It does not matter if the theme is lotus or ipod or any other themes. Once you get a firmware dump that works properly, you can always re-theme it to your liking.
