Restore Old PSN Theme to Jailbroken PS4 via System Backup Files
Hello. I am very new to this and have just recently jailbroken my 12.02 PS4 slim two months ago. I was hoping to find my brother's old PS4 theme called "Neon City Ride" by Xposed that he bought years ago as a fpkg but alas. I wanted to ask if it is possible to restore my system backup of my pre-jailbroken PS4 and get that theme back then install Goldenhen again or is that not going to allow the theme to be usable? I thought maybe I can restore my ps4 back to the pre-goldenhen state with a restore of the March back up then access the theme that way but I am not sure if it will be available. It was my brother's main account theme, so whenever he logged into his account, it automatically started. Is it possible to make the theme accessible since his account is also part of the system backup?
If I am not making sense, I'm sorry. English is not my first language.
tldr: I have a jailbroken ps4 and I want to restore a previously bought PS4 theme via using a pre-jailbreak system backup. Is it possible?
