Hi Everyone
                  I'm a newbie to the forums and fairly new to re flashing phones, I am computer and O/S savvy, but I cannot for the life of me figure out how you extract stock rom files so you have a visible CSC. file.I am trying to re flash a Galaxy GT I9000 to the stock VNZ rom
When I extract the roms I get a Tar file and SS_DL.dll.
If I then extract the Tar file I get a bunch of other files.
If I extract the cache.rfs file I get two folders system and META-INF.
Inthe system folder is a folder called CSC. 
But none of the files in this folder is a "CSC.tar or md5 file.
Am I missing something? or is there some trick to finding the usable CSC file within these archives, do I have to change an extension? is there something I havent extracted?
This is driving me nuts! I understand the need for this file as without it a boot loop ensues.
I have searched every forum I can find and it seems everyone else always finds this file in the rom's no problems. What am I doing wrong?
