PS4 Custom Home Menu, the early steps of PS4 unofficial themes?
Earlier this month, PS4 Scene member Senaxx published a screenshot of a PS4 Dev unit running firmware 1.76, with a modified icon on the main menu. No additional details were posted, and most of the scene websites just dismissed the post. So did I.
So I was kind of surprised to see this piece of news on many of the scene websites today. And now I feel like I have to mention it or people will call me out on this one.
What is this?
People running on firmware 1.76 have a way to customize some of the icons on their PS4’s main menu. This is apparently thanks to the (unencrypted?) SQL-based database that powers some aspects of the PS4’s interface and registry.
The process is not necessarily groundbreaking and not directly security or exploit related, but what made it newsworthy recently is that people have been able to reproduce it, and it seems to be reasonably simple, for PS4 1.76 owners.
According to fx0day on playstationhax, the file to edit can be found in /system_data/priv/mms/app.db. Just open it with your favorite offline SQL editor such as this one, and start digging for cool stuff you can modify, then reupload the file to its location on the PS4 with your favorite tool (PS4 FTP comes to mind).
This could be the very first step for user-customization of the PS4. We all know how much people love to customize their experience, so by digging into some of the unencrypted data of a PS4 running on Firmware 1.76, maybe we can expect more customization moving forwards.
In the meantime, enjoy a few screenshots, courtesy of the members over at playstationhax, + the original one from Senaxx.
