w550 flash files

[senter]

can i also change the order of files.....like .fbn first then cusom and then .mbn......???

First: Main (*.mbn)
Second: File System (*.fbn)
Thirdly: CDA (Custom file it's *.zip archive)

When you flash File System (FS) must do custimize on File System with CDA file (*.zip archive).
