Prior to about 2 weeks ago, I had SM 4.2u softmodded with cIOS rev14. Everything was working great. Then I couldn't get Metroid Other M running and an upgrade to rev17 resolved it. However, ever since then some games have been crashing mid-game, and my guitar hero and rock band games - both from USB loader and from the original discs - began hanging for a second or two several times throughout each song, throwing the game off and breaking streaks. I tried reinstalling rev14, but this didn't resolve the problem. I decided, having seen some guides like this one and knowing it is possible to recover from a 4.3 update, to try the official 4.3 to get my Wii back into a clean system state. It appears to have fixed the problem with the hangs in Guitar Hero, so I'm quite happy with that.
HBC is still there, and standard homebrew such as emulators and such work fine. I tried existing trucha bug restorers, i IOS236 Installer v3 MOD (v4 as well), and TBR 1.13 - neither has the access to overwrite the necessary IOS. Nor can Any Title Deleter remove the 254 stub. None of the USB Loaders do anything more than crash at a black screen.
I'm waiting for the opportunity to get to the library to borrow a copy of SSBB or Lego Indy. In the meantime, can you advise if there's a way of getting the needful done directly through HBC so that I don't need the game? Also, does any of the info above ring any bells that would suggest a potential problem with using this guide? Any advice or relevant info would be much appreciated.
Goal is to play my backups on a WBFS USB drive as I used to do.
