    There must be a way to execute a “panic” trigger for the SysCon chip to revert to previous firmware without this electronic work, as there must be a way that PS4 “knows” when the firmware upgrade has not been executed correctly, and thus triggers a “Firmware revert”

      I’m assuming that in most cases, such a “panic” would trigger a database rebuild at best… ? But There might be ways, yes.

      My method enables debug mode on the syscon chip. Meaning you can set breakpoints, jumps and start stop commands. So yeah maybe we can use this to manipulate how it handles updates.

    What would be really cool is a chip that let’s you select which firmware boot at startup
    Dual onboard syscon chip
    Dual onboard sflash chip
    Dual sata port

    Everything soldered to the ps4 replacing the original chips, an hardware switch to select wich system to boot up

    I don’t know if it would be cost effective, but sure as heck it would be very cool
