    ARE YOU KIDDING ME? ARE WE GOING TO START A FLAMEWAR OVER EDITING BOOTROM? ITS IN THE FUCKING NAME. ROM MEANS READ ONLY MEMORY.

    downgrading will not be a thing with the eFuses in place. although doubtful, a partial downgrade would be the closest thing to a downgrade that would be possible on the Switch assuming the system will boot and not blow the tamper eFuse in that state.

    well, from what it has been said in this thread (and i assume you havent read the OP with that answer) it will be possible, but with the exploit we would need to do it, downgrade would be obsolete

    The original xbox says hi. Everything is impossible until someone figures out how to do it.

    You can probably open the switch, remove the cpu from the board, decap it, fib the chip (https://en.wikipedia.org/wiki/Focused_ion_beam), repackage it, resolder it to the board. That would be difficult to do today, but not necessarily impossible.

    It took ages for the ps3 to be hacked completely. Sometimes it takes a while to figure things out.

    If it is a mask rom and not an prom/eprom/eeprom/flash then it still doesn't make it impossible to modify it. It's essentially made out of a grid of connected/unconnected gates. You can modify it if you have the equipment.

    Exactly this. We would need to be handed control directly by the bootrom to bypass the efuse verification and use an outdated firmware. And a bootrom hack would make downgrading useless.

    Nintendo would likely put the eFuse verification into the bootrom, for maximum protection.

    Proud to be Portuguese but I am in USA.
    Me too. That's why I dont like America. Guess what? I live in America thanks to my parents, sighing. Made fun of somebody who doesn't natively speak English is a no no. In Europe, they dont made fun of somebody who doesn't natively speak their language.. At least in my country. They are very understanding people. What's wrong with America ? Tsk tsk.

    Given the verification value changes with each update I'm pretty sure it needs to be in an area that can be updated. Although I suppose there would be the possibility the efuse checks are done via a specific algorithm in the bootrom. Either way according to the article I linked on Wololo.net the check causes a panic in the early boot chain not the bootrom. In short I'm pretty certain you're wrong.

    It seems that each firmware version includes an encrypted hash which is checked by the firmware to determine the number of fuses. Unless you have the correct encryption key you don't have a chance.
