Well,

I have just flashed the phone with
W995_R1EA028_MAIN_GENERIC_HI_RED53.mbn
W995_R1EA028_FS_WESTERN-EUROPE_RED53.fbn
and
C905_1209-4776_R6A_GENERIC_ADRIATIC.zip

It still works fine, it has the very same games and none of them are removable.

Is there a change to get it game-free or shall I throw it to the trash?

Thanks,
Trollsblood
