Switch with 14 burnt fuses, rebuilding emmc - firmware version

james28909 · May 18, 2022

ok i am about to rebuild my emmc from scratch. ive used lockpick and have all the necessary keys from what i understand. one thing that is snagging me is that i have 14 burnt fuses and i am trying to figure out which firmware to use.

in this list: https://switchbrew.org/wiki/Fuses#Anti-downgrade is shows 14 burnt fuses as having 11.0.0-12.0.1.

so can i just use 12.0.1 as the firmware? the switch just checks for fuse count right? even if i was to use 11.0.1 it would work? if so i will probably just use 12.0.1 as the base firmware to rebuild with. but if someone could elaborate on this it sure would be appreciated.

thanks

For firmware 11.0.0 to 12.0.1 the expect fuse count fuse count is 14, so you can go with one these firmwares.

AFAIK fuses only matter to boot OFW, if you use CFW you can upgrade or downgrade as much as you want without caring since CFW ignores the fuses altogether.

There is 1 caveat, the gamecard has a firmware of its own which only sometimes is updated. If that happens trying to use the gamecard slot on a lower firmware than the current firmware of the gamecard will not work (not even CFW can ignore that) other than that you should be ok. Also IIRC you cannot have an higher version of the gamecard firmware at emunand than sysnand and vice-versa because it doesn't matter where the update happens, once updated it automatically updates on both sides, that's one part of the Switch that hasn't been 'hacked' so far by the scene.

Just be aware that booting OFW will automatically burn your fuses to match the firmware you are booting into.
If you boot CFW (atmosphere) by default? it will not burn any fuses and will even disable the gamecard slot in situations where it detects it would be automatically updated otherwise.

btw at some point you will be 'forced' to use a newer firmware because newer games will just not work with older firmwares.

Your fuse count is for firmware 17.0.x, it explains why 7.0.1 refuse to boot.
