I did it this way:
* Upgrade your Wii to 3.4E
* Read the Softmodding guide for dummies and install the Homebrew Channel
* Install IOS16-<somethinghere>.wad from the normal Wad Manager
* Install cios_fix.wad using the
Wad Manager for IOS16 (which is the same as Custom WM)
* Run IOS Downgrader
* Run cIOS Downgrader (choose 3.2E)
* Run Starfall (all options except for the region free stuff)
* Install cIOS_249.wad with normal Wad Manager
* Install BackupChannel.wad with normal Wad Manager
* Install IOS38-<somethinghere>.wad with normal Wad Manager
* Run Mii Channel Updater (choose Yes)
* Run IOS51 Shop installer (choose Yes twice and then No)
I've put Any Title Deleter on the SD-Card as well and used this to verify that there's no IOS249 isn't used when starting with the install. If it is installing cios_fix.wad will probably give you a -1035 error. If you get a -1022 error you should try another cios_fix.wad (
