hey, you can also extract the FS to get the default color themes (*.ble)
To do so, you must download Main2raw & SEFStool4 from here
extract it and drag your FS into it to make RAW file.
then open cmd (Command Prompt) and go to the directory which contain raw file
then type
sefstool4.exe rawfilename.raw
it will extract the fs, you can restore it.
