Hacking Help to extract CPK files after using CFW2OFW Helper Meta

[smkmrs8]

Hello, everyone!

I need some help extracting CPK files after using the CFW2OFW Helper process.

I downloaded PES 2018, extracted the CPK files that were inside the USRDIR folder, modded a lot of things, packed the files again, used CFW2OFW Helper to make them compatible with the PS3, and everything worked very fine — until I needed to modify the CPKs again:

None of the CPK files can be extracted again! In some tools, I get the error: "the file is corrupted", while in others the error is: "this is not a valid CPK file". This doesn't make any sense, because the PS3 is reading these files perfectly.

The point is that I can't mod the original unmodded CPK file, because I want to make some minor changes without losing the major ones I made before, and I don't have a backup of most of my modded CPK files before passing through the CFW2OFW Helper process.

I don't know if it helps, but I have uploaded two files: the first one is a CPK file before passing through the CFW2OFW Helper process (which can be extracted as normal), and the other one is the same CPK file, but after passing through the CFW2OFW Helper process (which can't be extracted anymore) — I need to know how to extract files similar to the second one.

CFW2OFW Converts to . format NPDRM that sony uses on games Psn.
you need Decrypt files
use TrueAncestor_EDAT_Rebuilder_v1.65.

Thanks for your reply!

I have downloaded TrueAncestor, but I don't know where to place the CPK file nor what command I need to use. Can you help me, please?

send me a file cpk .

This is the CPK file I want to decrypt the most: mediafire/file/63p10km9b314ldi/dt36_ps3.cpk/file
(the dot and the com after mediafire is missing because the forum doesn't let me use links)

Can you apply the explanation to another file CPK?

I figured it out! It was double-encrypted. I followed the steps in your video, and after getting the .dat file, I renamed it to .sdat again and repeated the procedure, which worked!

Thank you very, very much for your help! You're a true hero!

I may be wrong, but this file can't be decrypted. The only person who has the key to do so is its owner. The best thing you can do is ask the owner to share the files you need with you.
