Para este tipo de parches solo tienes que hacer la carpeta gfx para colocar los iconos que deseas cambiar, pero segun ese parche tienes que hacer una carpeta ini, no habia visto este tipo de parche, yo tenia este parche en mi w800 y funciona perfectamente, te sugiero que lo coloques, solo haces la carpeta sysgfx en la MS asi /card/sysgfx

Código:
;W800 SW-R1BC002
; change internal phone graphics
; 1) put XXXX.PNG to folder /card/sysgfx
; where XXXX - hex code of an icon to change.
; 2) restart your phone
; ?????? ???????
; 1) ? ????? /card/sysgfx ????? ?????? XXXX.PNG,
; ??? XXXX-?????(hex) ?????????? ????????.
; 2) ??????????? ????.
