I read somewhere it bricked someones console. Doesnt seem anyone has a clear answer to what exactly PS3 PRO 4K actually is or does. It looks like a theme but surely no theme is in the hundred mb catagory heh.
Question- does it make a backup incase something goes wrong? And can it be removed without breaking anything?
People usually say it bricks the console, but that's not true. What typically happens is they turn off the console while the installation is in progress, which can cause a black screen or force the system into recovery mode.
A simple firmware reinstall fixes the issue. The installer creates a backup of the flash files before installation, which can be restored during the uninstallation process.
As for the differences between them, watch the videos I posted here.
The main difference between the Lite and Premium versions was originally based on user type ,Lite for basic users and Premium for advanced users, mainly due to the available features and package size.
Now that I support more firmware versions (4.84~4.92), and with new ones being released every year, the package sizes have increased to accommodate them. Lite was originally around 300 MB and Premium around 1,6 GB, but with multi-firmware support, the Lite version is now nearly 800 MB, and the Premium version has grown to about 3.5 GB. (due to multiple vsh.self, explorer_plugin and the random XMB feauture on Boot that is powered by webMAN Mod)
