I found the TruchaBugRestorer pack i have downloaded previously. I only used the cIOS Installer from this pack originally, but it includes the Bug Restorer app also. The readme says:
Sounds like me?Trucha Bug Restorer 1.0
Q: What's this good for?
A: The TBR is to get IOS with the trucha bug on all Wiis with system menu up to 4.1. Usually the error codes -1017 and -2011 indicate that the trucha bug is required and missing.
I read the readme.txt (sounds a little hairy) but I don't know which options I should choose when I run the TBR app. I assume I should be choosing IOS 38, then I get these options:
Downgrade IOS 15
Restore IOS 15
Show boot2 info
any help on this one?
