The firmware things! HELP!!!

Okay, I've posted another thread with questions on what things I should have to flash my phone.. And Seamonkey said that I should get

MAIN - GENERIC
FS - EUROPE4
CUSTPACK - EUROPE4

and all this files must be same version (like one in your phone R8BE001) RED_52..

And all the R8BE001 firmwares are for CID53!! FUCK! My phone got 52 -.-'
