phone security code needed for CID53 W610 firmware downloaded from topsony

i successfully flashed by k550i phone to w610 using the following files and jdflasher:

W610_R8BA024_MAIN_GENERIC_NA_RED53.mbn
W610_R8BA024_FS_CENT_EUROPE_RED53.fbn
HB1-06_Gen_CDA102568_207_R2A_GENERIC_CENT_EUROPE.zip
Acoustic_original_W880i.rar

now its working fine (thanks to topsony team and den_po). however its not accepting any phone security code. without this i can't format the memory card.

i tried all the default ones but none work. i also searched for old threads. am i missing something?

SEUS says my phone has the latest software so I can't revert it to the default security code. Where is this security code stored? Anyone?

It's in GDFS, but on CID53 cann't read GDFS.
On CID52 can with XS++ reset (again to 0000) or with Setool can read your phone lock code.

So when I flashed my phone the GDFS got overwritten since my old security code is also not working.

Who uploaded the firmwares by the way? Perhaps he/she would know the correct security code embedded in the firmware.

I flashed my phone again with the same files and somehow now the default security code is working! I dunno how this happened but I'm happy.
