Although McDonald doesn’t appear to have discovered the PS5 jailbreak himself, he does show footage of it in action.
At this stage the jailbreak is allegedly extremely limited – it‘s only said to work on PS5 consoles with firmware version 4.03, which was released in October 2021 and replaced with version 4.50 in December 2021.
According to the exploit’s creator, it may be possible to apply the jailbreak to PS5 consoles with earlier firmware versions than 4.03, but later firmware versions won’t work at the moment.
Even if a player does have a console with the 4.03 firmware, the exploit’s creator warns that it will still only work around 30% of the time, usually requiring multiple attempts to execute.
