Prolapse won't reach PS5 14.00 or 14.10: the AIO bug doesn't corrupt memory the way it does on PS4
Jose Coixao, who announced Prolapse, said on November 4 that the odds of it reaching PS5 14.00 or 14.10 are close to zero. The public jailbreak still ends at 13.60.
Why it fell through
Prolapse was going to use a bug in the AIO subsystem, the same class of flaw that leaked for PS4 14.00. On PS5 it doesn't corrupt memory the way it does on PS4. Coixao (notnotzecoxao) said so in two posts and agreed with Sonic_Iso, who had already warned him and Echo Stretch that this corruption wasn't possible on the console.
He had voiced doubts on October 30. The code he shared was labeled non-working, and no one ever showed Prolapse loading a jailbreak on those firmwares. Coixao says another AIO bug could still turn up later.
Where each firmware stands
The public route remains Relapse with Byepervisor-Reborn, up to 13.60. Separately, Gezine showed debug settings open on 14.10 on October 19 using a private kernel exploit. He says the one he used on 13.xx was patched in 14.00 and that this one isn't Relapse. None of that work has been released.
Earlier scene analysis suggests 14.00 still has the older hypervisor bug, which 14.10 closed. Even with a new kernel exploit, you would still need a separate hypervisor bypass.
A retail PS5 can't be downgraded. If you're on 14.00 or 14.10 and waiting for news, don't update: 14.22 only lists security fixes.
