First, have a re-read of those rules you accepted earlier today. You would have seen that we do not allow external links to outside guides to be posted. We don't need to know a specific guide is crap, we already know it, so don't confused those who don't know it by linking to it.
As for your process, we would have preferred that you followed Softmod Any Wii from the start vs. cherry picking the parts you want, though the syscheck did look good. Can you check the syscheck thread linked in my signature for the b19 link and use that to get a fresh syscheck? Don't break it up like you did with the b13 one, post the entire output within spoiler tags like you did above.
DSI error is usually when an app wants to use a cIOS that isn't installed or not installed correctly. But what I saw if the syscheck has things looking good.
What specific apps are you trying to run that is throwing this error?
