Recently PlayStation 4 developer Duxa (aka @Chrushev) made available a PS4 PKG Repackager which allows you to repackage fake patch update PKGs to work with your games on a jailbroken PS4 console. ;)

Here's what Chrushev had to say on the release, to quote: Hi all,

Few things off the bat:

1. I wrote this for myself in order to automate the tedious part of repackaging (see below as to what it does).

2. I tested it on Win 10 and Win 7, both worked for me but this was not tested beyond my machines, so please report any problems

3. Please do not tell me it has a exploit, some obscure exploit scanners mark it with a false positive (probably because its not a signed exe). It does not have a exploit, I do not want to mine crypto with your machines, nor am I interested in your personal info. There is no exploit... all mainstream AVs mark it as clean. If you dont trust it, dont use it (good rule to follow in general). exploit report is available here and you are of course welcome to run your own.

4. Do not ask what the passcode is for your package. Try the default (simply press enter), if it doesnt work then you may be SOL. No one knows what it is other than the original pkg creator. Everyone should use the all zero default.

Now to the good stuff...

What is this thing?

Its nothing more than an automation tool. It unpacks a fake update .pkg for you and prepares it to be repackaged.

Why would you want to do that?

Because there is a requirement that update pkg is created with the same image that you have installed. Matching CUSA is not enough. So for example, if you and your friend both live in London. You both have UK version of Horizon Zero Dawn, same exact CUSA. You go home and create a .pkg of the game, and your friend creates .pkg of the update on his console. That update will not work with your .pkg. It is imperative that the update pkg is created off of the exact game pkg that it will be installed on.

PS4 scene is young, a lot of dumps are done without updates, and you cant simply create an update later (not easily). To "fix" this, we can repackage the update with the game .pkg that you have (even if it was not created from that pkg) and the update will work. NOTE: CUSA of game pkg and update pkg still HAS TO match!

Will this allow me to run updates that require higher FW that mine (4.55 at this time)?


Can I use this with official update files?

No! This is only for fake pkg updates. This essentially re-pairs the fake pkg update to a new master fake pkg game

What is required?

You will need:
  • .pkg of the game
  • .pkg update (with matching CUSA)
  • this program
  • gengp4 v1.8 or later (google for it)
  • orbis-pub-gen (google for it)
What is the process?
  1. Put this program in the same folder as the update .pkg, to avoid headaches please make sure there are no spaces in the pkg names
  2. Run the program. It will ask you for the 5 digit CUSA
  3. It will then ask you for the pkg name (remember to use Tab to auto complete, if you dont know how that works, enter first few letters and press Tab... handy for long names. Will only work if in the same directory.)
  4. You will be asked for passcode. The default is already coded in, so press Enter without entering anything. Alternatively you can enter one.
  5. The program will execute (timing depends on the size of pkg, about 2 min per Gb from my testing, it will give an estimate).
  6. If all goes well green text will appear with remaining instructions you have to do manually with gengp4 and orbis-pub-gen. Luckily these are just a few clicks. I do a lot of checks during the process, if something is wrong you will get an error.

I get an "Error 3" as soon as I try to launch it. I don't understand what I could be doing wrong the first step is so basic.

@Chrushev Is there any way to have the program not use C:? My C: Drive is to full to extract bigger games, and i can't uninstall programs to make more room etc because it is a computer from work.

Hey guys,

I tested yesterday duxa's script and it's not really a repackager. It helps to extract pkg and adjust tree directory. After that it remains 2 important steps : generate gp4 and build pkg. But these steps are problematic to automate.

So i decided to work today on this purpose. I have just finished and managed to script all repackaging process. I made several tests and rewrite to improve portability and performance.

@Chrushev Thanks for your work :)
@stripnwild i will try to post my work tonight (y)
I tested half dozen updates and it works great :bananaman:
I have a little adjustment to implement tomorrow.
I'm going to prepare a post (a new thread ?) to explain all in details.
It is really appreciable to be able to repack fpkg updates with a simple click (y)

@tooretoo42 awesome news!!! Hopefully you can make it so it can execute to a specific drive also, instead of only utilizing the C: Drive (which would be awesome for me, so many update files to repackage!)
