Yeah ive an idea
Next grab WiiScu
http://wiibrew.org/wiki/WiiSCU
and update JUST THE SHOP CHANNEL using this tool...
Finally
Download anytitledeleter DB (it will tell you what the channels are rather than just listing the ID of said channels)
http://wiibrew.org/wiki/AnyTitle_Deleter/AnyTitle_Deleter_DB
Load it up in the HBC and make sure that the stubs of opera are deleted....Then SHUT YOUR WII DOWN FOR 5 MIN ( i know this sounds a lil crazy but ive had to do it to rid the 20XXXXX error on the wiishop...
(if you are using a wireless router that shares bandwidth with your PC make sure you turn off any P2P applications or "bandwidth hogs" just helps keep your connections resources allocated to the wii's tasks rather than other things that may be attached to your wireless router...)
Turn your wii back on go to the updated shop channel and download The New IC Chanel for FREE
(so long as you did the shutdown you shouldnt get that 20XXXXX error @ the wiishop channel)
Ive had issues with this on 3.2 on my own wii and on my friends 4.0 so its just a hit and miss deal for some reason if you power your wii down for a while then try to download the channel again it will usually work!
Hope that helps bro good luck!
