Here what i did
I got 3 wiis
Wii 1 was connected to flatmii and had wankos 4.0 on it worked like a charm
and also from disc same iso, installed ios249 and ran it in the bkuploader
Wii2 was a stock 4.0 that had no cios- was a no go on autoboot and flatmii
Wii3 was an updated cioscorps 3.2e with ios249 to 4.0 stock, did not work
just crashed at the install mariokart channel
So theres my test btw i took all the wiis apart what a mess lol
All the wiis where tryed with flatmii Auto and none Auto boot and the iso on disc with yasom mod chip
UPDATE !!!!!!
4.0 stock wii with iso249 running the backup loader works for installing the homebrew channel from mario kart
