Boot into preloader
Download IOS60-patched.zip and extract to sd:\wad
Download 4.1U-RVL-WiiSystemmenu-v449.wad to sd:\wad
Boot into preloader and click load installed file
HBC should start
Use ios249, load SD
Install system menu 4.1
Then download preloader and reinstall it
Put the hacks.ini file on sd:\
Hold reset and boot, preloader start
Enable desired hacks, I recommend disk update block, remove diag disk check, and any others you like.
You can try to update again, or just leave good enough alone
Reinstall HBC loader into preloader if you wish to autoboot into hbc
Or install the forwarder of your favorite loader to autoboot into it, like usbloader gx.
If hbc does not load, place the boot.dol of wadmanager on sd:\
then click load/install, and load boot.dol, wadmanager should start, if not download another version.
