I have recently semi-bricked my Japanese Wii to 4.0 (I think it is semi-bricked by a US disc 4.0U update that i inserted and updated).
Anyway, 2 questions:
1) How to unbrick from its current state?
2) If I manage to unbrick successfully, any recommendation on how to play backups from now on (e.g. soft mod, usb-loader ... etc?)
