Hacking 3.4U, WiiKey, LU31 and USB Loader?

[Aku]

OK, have had my Wii for a couple of years, had to update the WiiKey for Super Mario Galaxy. All has been good. Last week I bought a Motion Plus and Tiger Woods, that updated my console to 3.4U. Home Brew channel is installed and I assume working

Now it is USB loader time! Bought a Toshiba 320 USB drive and getting ready to do this. This is the steps as I understand them. If you could please look them over and let me know if something is wrong, out of date or there is a better way of doing something, I'd appreciate it.


Step 1: Downgrade to 3.2
- Install IOS16-64-v257-prod.wad
- Install cios_fix.wad
- Run IOS Downgrader
- Run Custom IOS Downgrader
- Follow the prompts, install Version 3.2U

Step 2: Upgrade 4.0U
- Install BootMii (with Home brew and DVDx, I guess)
- Install cIOS36_rev10-Installer
- Run Waninkoko Firmware Updater v4.0

Step 3: USB Loader
- Run Waninkoko's USB Loader
- Run WiiCoverFlow (???)

Do I have to install Patched ISO60? Have been reading forum and didn't know how the wiikey fits in, assume it doesn't

Edit: Ok so without waiting I jumped and did it, things happened in a different order than I had assumed, ie the first thing that happend was BootMii loaded, but none the less they are done.

I assume its the DVDx that makes my drive sound like its going to break, before that it was much quieter...
