Developer ps4miner has released a patched version of the PS4 Media Player (with VR support), which will run on 5.05 consoles that have not been PSN activated. This will let you play video and music through the PS4 Media Player on a hacked 5.05 console. And it will answer the question: “How do I Install Media Player on PS4 without PSN?“.
The patch escalates the player’s process to let it run with going through the regular security checks. The developer states that due to how this is just a binary patch with hardcoded offsets, this is only compatible with 5.05, and probably 5.07. On other firmwares, he expects this will not work and trying to run the app could reboot your console.
In the hacker’s own words, “it’s not the best variant of fixing this app, but it works for now (as a temporary solution).”. Users have reported this works fine, including those of us who want to use it in combination with Plex.
More details on how the patch was made can be found at the source link below.
