Backporting is the process of applying changes from a newer version of a software program to an older version. In the context of the PlayStation 5 (PS5) jailbreak, backporting is used to apply changes from a newer version of the PS5 firmware to an older version that is vulnerable to a jailbreak exploit.
Backporting can be a complex and time-consuming process, but it can be essential for PS5 users who want to jailbreak their consoles. By backporting changes from a newer firmware version, users can gain access to new features and exploits that are not available in the older firmware version.
