Could this be solved (hacked) with a MITM? Spoof the required responses to get the current time via raspi or something?

  If you read the article you'd see that there's already a custom firmware that solves it.

    With the caveat that you need to be running an old firmware to install the custom firmware, and there's no way to downgrade The current last exploitable PS4 FW is 7.55 released in August 2020, if you updated to 8.00 or newer you're SOL for now

      What prevents downgrading? Is simply a software issue or is there some hardware mechanism in place?

        Don't know about the ps3 but the xbox one has efuses that get blown with most firmware update and prevent downgrading in any form, don't know whether any workaround has been found yet

        The PS4 firmware is encrypted with a per-console key embedded in the CPU, so to downgrade you would need a copy of the old firmware taken from the same console. Technically you can downgrade to exploitable firmware but only if the system had exploitable firmware in the first place, and had its firmware backed up, before being updated.

        In some newer systems (the Nintendo Switch) there are hardware fuses they blow with each update. Their software won't work if the appropriate fuse is already blown.

    That's not helpful. Yes I read the article, and yes I get there is a "solution", that wasn't my question. I want to know if the option I suggested is viable.
