CBHC is pretty awesome thus far. I found out the following:
Booting using the default fw.img-less patching is around 30 seconds (never timed it). However, this method of patching is limited. WUPserver and FTPiiU Everywhere don't work. WUPclient can't connect and FTPiiU Everywhere can only list the directory contents of the SD card. Also, the sigpatching doesn't get reapllied when exiting System Settings.
Booting regular sysNAND CFW from the CBHC menu works (no infinite loop or double loading). However, the Wii U will freeze to a black screen when exiting the channel version of the Homebrew Launcher. Also, when exiting system settings it will bring you back to the CBHC menu.
Booting coldboothax CFW works as long as you have syshax.xml. It doesn't double load and the Wii U goes from power on to the menu in about 45 seconds. This saves about 20 seconds over the old coldboothax which caused the double load. Everything else works as it did with coldboothax. No freezing when exiting HBL, WUPhax/FTPiiU Everywhere works, and iosuhax reloads when exiting System Settings.
You can select what you want to autoboot (Start Menu with patching, load HBL, or boot fw.img) or you can leave autoboot disabled.
I just can't figure out how to cancel the autoboot.
Thank you
@FIX94 !
Edit: You cannot Autobot. Stupid autocorrect.
