I own a 4.0u hard modded wii w/SUNchip. I am trying to softmod it using DOP-mii ver14. I keep getting error -1 which basically it tells you its unable to downgrade to cios15, when trying to install Install I0S36 (v3351) w/FakeSign. my current ios is IOS60. whats the workaround? can I just use the cIOS downgrader to downgrade my wii to cios15?
