so unless your deadlyfoez with an infectus, is there another way of doing that? Existing homebrew or otherwise? I'm just curious, thx
I can't code anything to write to the seeprom, and thats what is needed first before you can downgrade boot2 blocks. The infectus would let me write an older boot2, not change anything in the seeprom. It would actually be easier to just have a homebrew app that does both ends of it instead of tearing apart the wii and whipping out the infectus.
I wish I did have a homebrew app that could let me downgrade the boot2 version in the seeprom, but I don't and it's really pointless anyways for any normal user. Maybe if there was some usable exploit in older boot2 versions that would give us anything more than what we already can do then it would be worth it, but there is not any worthy reason.
There are a few people that have some apps that can write to the seeprom, like one that can remove the korean key, but no one is willing to share them because if something does go wrong while writing to the seeprom then your wii is fucked for good and no one would ever be able to fix it.
The only publicly available homebrew app that writes to the seeprom (that I am aware of) is dop-mii, and IIRC that function is based off of bushings code.
EDIT: @OP, If you care for any more in depth info about boot2 versions, and using the older IOS's that were made for older system menu's, you can read;
