I soft modded my 3.4 wii using this tute 4.1 and below Firmware Softmod Guide - All Systems Except For Korean (LINKED 4.2 GUIDE)! all went well.
I then decided to update my version to 4.1, all seemed to go ok with that.
The problem I have is that when I insert an original game the disc channel does not recoginse it, the wii remote also looses connection.
Any help would be much appreciated!
If you are using preloader disable the region free option.
