hi. i have a question about installing an original firmware on the SAMUSUNG I5500

i found the firmware on sam mobile web site.

i downloaded the installation guide.

on the guide i read that with ODIN i have to select these files:

BOOTLOADER, AMSS, PDA CSC with MD5 extension.

but on the zip that i have downloaded i found only

these files

AMSS , BOOT.IMG, CSC.RFS, RECOVERY.IMG, SYSTEM.RFS

my question is how can i flash the original firmware if i don't find these files ??

thank you very much
