Also got an issue with a friends' wii here.
I'm using the 15% update trick to not get the duplicate channels.
But for some reason the disc with update works on my wii but doesnt on his. We got it modded at the same place, both with 3.1U and 1.9g firmware. I checked his wiikey settings region free is ON.
When I tried to re update the wiikey to 1.9g the testing update, failed. So I assume this is where the error is coming about, anyone know how to fix this? Oh also his Wii can still play all other burned games and Mario Galaxy so the 1.9G firmware is still working.
