PS4 4.05 Patches and Hooks to Enable FSELF / FPKG Loading by IDC

Since @flatz shared on Twitter his awesome PS4 Fake PKGs & SELF / FSELF Write-up, and following the PS4 SELF_Info.exe release and recent 4.05 Experiments PlayStation 4 developer IDC made available some PS4 4.05 patches and hooks on Github to enable FSELF / FPKG loading with ShellCore patches (for fake PKG support) implementation yet to come.

Download: ps4-fake-405-master.zip / PS4Fake405 (Simplified payload makefile independent of libPS4) / GIT

To quote from the README.md: PS4 Fake 4.05

Patches and hooks to enable fself/fpkg loading for 4.05, as described by flatz in his writeup.


ShellCore patches (for fake PKG support) not yet implemented.

• fake_installer - Add payload and installer. (Compiled fake_installer.bin by akenateb and midos2010 with a compiled FSELF.zip working download link from DomyGX)
• fake_payload - Fix fake_payload.x for normal builds. (Compiled fake_payload.bin by akenateb and midos2010 with a compiled FSELF.zip working download link from DomyGX)

VVildCard777 lets us know "this is just step 1 fself loading, read the readme, shellcore patches still to come" as @zecoxao also notes on Twitter while you can "compile, run, and replace a system app eboot.bin with an fself, then try to boot the app. it'll run your homebrew instead" he reminds us "it's be better to wait for fpkg support."

Finally, if you haven't checked it out yet recently m0rph3us1987 added some PS4 5.01 kernel slides to fail0verflow's PS4 kexec repo.

Theoretically, if I replace an internal app with my homebrew (backup original and copy my homebrew over it), later I can run my prog if I start the internal app? Thatvis correct? But we need the exploit change to use this method? Or how to use the exploit and my homebrew with this?
