(adsbygoogle = window.adsbygoogle || []).push({}); This is Cod4, but this works with MW2, Cod5 too! But you need HDD Decryption with FW under 3.30

1st step:
IW added an additional file header to the ff-files (12-bytes: 49 57 66 66 75 31 30 30 05 00 00 00) and you need to remove it first before you can decompress the file.

2nd step:
After removing the header, your file should begin with 78, the header for Zlib with max./best compression. Store the file (don’t overwrite your sourcefiles, always create backupfiles first) in the folder where the ff_iw.exe is located. Open or create the decompress.bat or anything like that, use the command “ff_iw –d NAME_OF_THE_FF-SOURCEFILE NAME_OF_THE_NEW_GENERATED_FILE” in it and run the bat-file.

4th step:
When you’ve edited the content and want to test something you only need to compress the file again. Use or generate a compress.bat or anything like that, use the command “ff_iw –k NAME_OF_THE_EDITED_SOURCEFILE NAME_OF_THE_NEW_GENERATED_FF-FILE 9” in it and run the bat-file. Don't forget the value 9 for best compression!

Hints:

In front of the files you will find the length of the file. 4 byte in little endian (reverse order). It often makes ripping of the files easier when you use the length.

Wow, nicely written.

What he said. Nice post.

What does this do?

i think it might could be work BUT

how to get the patch from psn without newest fw???
I dont know any way to login to psn bypassing fw update.

so if we realy can decrypt and edit patch this was how can we get the patch on the ps3?

and will it run if we put it back (no checksum etc?)

i have an ps3 3.00 but without BD drive and BD board so i cant download the patch.

wow, like ur tenth post that u just copy pasted from an other Forum.
Give credits next time.
- repped

Seems like ally ov messing around removing byte etc etc

Use offzip -a -1 -z -15 (full fastfile here) (empty folder here) 0 then press enter

Fully decompiled patch edit what you want . And once done with editing use packzip

-o 0x00000012 -w -15 (modded file here) (original ff file here) then press enter

All modded data will be injected to correct offsets

the fact that the command prompt is in german and you're from the USA is enough to show this isn't your tutorial
