    Posting this at ps4miner's request: This is a patched version of official PS4 Media Player 3.50 (VR supported) so it can play music and video on non PSN-activated console.

    Will work only on 5.05/5.07 FW because it includes a kexec part with hardcoded offsets (sorry <5.05 guys, my bad).

    Running on other than supported FW will make console to reboot.

    Also do not forget to turn On MPEG-2 switch at "Debug Setting -> License Activation". Player is checking for it.

    It's not the best variant of fixing this app, but it works for now (as a temporary solution).

    Basically patch does two things:
    1. It escalates privileges for the mplayer's process, so it can freely access the stuff it wants.
      • *sonyCred = 0xffffffffffffffff; // sceSblACMgrIsSystemUcred
      • *sceProcType = 0x3801000000000013; // sceSblACMgrGetDeviceAccessType
      • I'm not sure if both patches are necessary. Probably second one is enough, too lazy to check.
    2. It patches SceMusicCoreServer process in memory.
      • Function at SceMusicCoreServer+0x3640 will now always <return 0>.
    5.07 FW is unchecked but it almost certainly working (at least video should).

    It looks like official packages somehow got more privileges than fpkgs so some applications are failing to work properly.
    Probably a whitelist (which is coming from PSN on activation) or fpkgs lack of some sort of marker. More research is needed.

    I wanted only this particular application to work, now my work is done. I hope you enjoy it :)

    Access the PS4's Hard Drive (HDD) on 5.05 Guide by MODDEDWARFARE.jpg This weekend @MODDEDWARFARE shared a video guide from his YouTube Channel via Twitter covering some handy things that can be accomplished with FTP on PS4 including how to add your own profile picture, edit your trophy summary, backup save games along with deleting and blocking updates on 5.05 jailbroken consoles. :coolxf2:

    Since his PS4 Theme Creator guide, he's also recently detailed how to jailbreak a Nintendo Switch with free Custom Firmware (CFW) for everyone who owns one of those handheld video game consoles too. :gigglexf2:

  • PS4 5.05 Kernel Exploit Writeup Documentation by SpecterDev

    PS4 5.05 Kernel Exploit Writeup Documentation by SpecterDev.jpg As he did with the 4.05 Kernel Exploit and 4.55 WebKit Exploit, following the initial announcement and 5.05 Kernel Exploit release PlayStation 4 developer @SpecterDev has now made available via Twitter a writeup documenting his PS4 5.05 Kernel Exploit for others to examine and learn from. :notworthyxf2:

    To quote from the PS4 5.05 BPF Double Free Kernel Exploit Writeup.md on Github, in part: Conclusion

    Another cool bug to exploit. It should have been a trivial exploit, however Sony's new mitigation that prevents exploit devs from pivoting RSP into userland memory while in kernel context is quite effective, and some tricks had to be used to get the chain into kernel memory - but as demonstrated, it is beatable.
