Following the initial work from
Duxa (Chrushev) and my
testing I continued to work on my script below, which was then proceeded by
PS4 PKG Repackager version 6.15.18.
What is this ?
T42-repackager is a script that make quick and easy the
repackaging of PS4 FPKG updates (fully automated process).
Who did this ?
This script has been written completely from scratch by myself (inspired by duxa's unpacker).
Why should I use it ?
To resign FPKG update build with a different base because of signing problem (error ce-36434-0).
To modify and rebuild FPKG update for testing or modding purpose (don't release them as proper update).
What this script does not :
- Make coffee

- Repackaging Official Update (this script is about FPKG not PKG).
- Offer an interactive and elegant interface (you launch the script and take a coffee).
Before asking for anything :
- Read explanations in this opening post (OP) as well as the upcoming ones.
- Read comments inside my script and seek for readme.txt alongside.
- Take few minutes on search engine ...
Known issues :
- Inconsistent Software Development Kit and Required System Software versions
- The problem is only relevant for lower firmware 4.05/4.55 owners
- orbis-pub-cmd.exe overwrite param.sfo on the fly with higher values (see screenshots)
- As a workaround, open orbis-pub-gen.exe and rebuild from existing cusaxxxxx-patch.gp4
- This problem may already affect base and/or existing patch. In that case you should seek for original values then modify param.sfo and rebuild with orbis-pub-gen.exe
- Scenarios mismatch : "[Error] Number of scenarios was changed by the patch/remaster". Use proper fpkg base and/or update to avoid building errors. Otherwise try to overwrite playgo-xxx.xxx files in cusaxxxxx-patch with those present in the base fpkg.
Requirements :
1. a device with windows 7 or higher and a drive...
