    Now I wonder if you can actually go below 2.70?

    8th byte is 0C, so i just changed the 8th byte only a few times to see what would happen and sure enough the minver changed each time

    I would say possibly given these results...

    But like zeco reminded me there is the hardware compatibility to take into consideration. Even if you could install lower, would lv0 & lv1 actually work? Unlikely after a certain fw revision.

    Right. Spoofing it to say something other than it is, is one thing. But metldr & bootldr are still the same.

    That is the ps3 model & 0C is for a CECH-30xx.

    I bet changing it in IDPS will allow lower than min version to install, instead of getting an error code. But will just brick.

    Yep on metldr2 it's useless.
    On CFW compatibles, some lower fw may work, fully or partially, but I doubt you can go much lower anyway.
    If anyone tries, you better have a flasher ready & an original backup. Lol

    Something I thought was interesting was that when I set my model# to a NAND# on my slim it will only go down to 1.97, the lowest firmware for a NOR model.

    If I wasn't so lazy I'd hook up my flasher & give it a try lol
    If nobody else tries in the next few days I'll go ahead & give it a shot.

    Consensus here is I bought I PS3 from the pawnshop that had already IDPS spoofed and then updated to OFW to make like it was never jailbroke

    further thought makes me think I could have been banned recently possibly because maybe my console wasn't the only one with this IDPS

    several numbers in the ipds are unknown, so maybe one of them relates to the minimum firmware version?

    Changing just the 8th byte (IDPS/Taget_ID) changes the MinVer so I'm thinking this is the only number that tells the current FW what the MinVer is, does anybody know where CFW Tools (xia_plugin) looks to find MinVer @bguerville

    xai_plugin uses syscall 863 to get the minimum applicable firmware version.
    Just like MinVerChk I assume.
