Hi,
First and foremost, you need to ask yourself what game that doesn't have a backport for your firmware are you actually interested in?
If the answer is none then I would advise to stay where you are for the moment. You can always upgrade...
You have to be subtle. I would compared Ark Sama "Root keys" to Schrödinger's 😺. They simultaneously exist and don't exist. You don't want to piss of french person 😛
It depends on what you want.
Rule of thumb if unsure: Always stay as low as possible.
You have several ways to JB your PS5, webkit won't give you any advantages on that FW.
That’s currently impossible, you dump games decrypted as a folder or copy the retail pkg (encrypted) to another source.
You then need to repackage the files into a FPKG.
It’s a two stage process.
Make FPKG from folder dumps and exfat on your console?!
Folks, introducing to you the newest fpkg maker right through the console itself! (PS5) Free PKG Builder is the most stable version I have at the moment, with the crash during conversion...
