Doesn't matter. A vulnerable version of IOS36 won't run on new starlets. And a new version doesn't help you as it doesn't have the signing bug.
So like I said. The LU64fix.wad is the only option there is.
One thing I've already observed is that the installer uses an unpacked IOS36 v1042 (or at least parts of it) to compile cboot2. I doubt it'll know what to do with the LU64fix.wad file. If cboot2 as it is doesn't work on the LU64 Wiis, then it'd have to be rewritten to work off of that cIOS.
Still, I think that someone with a LU64 on 4.0 should try cboot2 out first before ruling it out as it stands. It can't hurt anything to try it.
For future reference here are the instructions he gave for setting up the directory structure:
QUOTE(WiiGator @ May 22 2009, 05:56 AM) Sorry, I forget that you will need also the following file:
/00000001/00000024/v1042/cetk
1. Copy
http://nus.cdn.shop.wii.com/ccs/download/0...0100000024/cetk to SD /00000001/00000024/v1042/cetk
2. Copy
http://nus.cdn.shop.wii.com/ccs/download/0...000024/00000004 to SD /00000001/00000024/v1042/00000004
3. Get a tool for extracting WAD files (I assume that the WAD Unpacker will work
http://www.elotrolado.net/hilo_bfgr-wadtools-v036_1010150 , on Linux you can use zeventig from
http://git.infradead.org/users/segher/wii.git )
4. Get a backup copy of a game and extract the file BOOT2-v2-64.wad.out.wad (on Linux you can use negentig from
http://git.infradead.org/users/segher/wii.git )
5. Extract the file BOOT2-v2-64.wad.out.wad and copy the files to the SD card. You will get the following directory tree on the SD card:
/00000001/00000001/v2/00000000.app
/00000001/00000001/v2/cetk
/00000001/00000001/v2/tmd.2
You may need to rename "tik" to "cetk".
You may need to rename "tmd", "title.tmd" or "tmd.title" to "tmd.2"
