How to remove the games from a SE W995?

Hello,

we own a SE W995, it works just fine, but has ~7 pre-installed games, what I cannot delete. (The delete option is grayed out.)

What would be the best option to get rid of them? (Optimal would be to have no games installed at all.)

Shall we go for another firmware?
Once we have one, are all programs free to remove?
The phone is operated in Germany (Western Europe) and it has no SIM-lock.

Thanks for your help in advance,
Trollsblood

ps.: for some reason the search option of the forum yields no results, whatever I try...

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
