How to enable flash menu on a branded w580i

[Qarlog]

I found a file that can enable Flash Menu in the phone without flashing it. Anyway, placeing it in FS probably means debranding anyway ^.^
The file was tested on w910i (DB3150) and w980i. I've attached so you can check this out ;) It changes CDA also so if anyone wants to use it, i'd prefer to edit CDA previously (<cda-number>1201-0116</cda-number>). Hope it helps someway. :D
