I installed Haxchi v2.3u1 using this config.
a=wiiu/apps/homebrew_launcher/homebrew_launcher.elf
b=wiiu/apps/sigpatcher2sysmenu/sign_patcher.elf
default=wiiu/apps/iosuhax/iosuhax.elf
All worked great. So then I loaded haxchi, then I loaded homebrew launcher and installed cbhc 1.2 it installed but got stuck after saying installation complete so I hard powered down and now the wii u bootloops!
