Long story short:
Bannerbomb: security holes fixed
Bootmii: firmware location overwritten
Homebrew Channel: removed by the system menu
cIOS: firmware locations overwritten
Preloader: removed by the system menu
DVDx: removed by the system menu
Here’s an update:
Bannerbomb: Use Bannerbomb v2, Smash Stack, or Indiana Pwns
Bootmii: Use HackMii installer v0.5 to (re)install.
Homebrew Channel: Use HackMii installer v0.5 to (re)install. HBC 1.0.5 will not be removed by the 4.2 update.
cIOS: Just reinstall.
Preloader: Wait for an update (if Crediar chooses to update it).
DVDx: Use HackMii installer v0.5 to (re)install. DVDX 2.0 will not be removed by the 4.2 update.
The really sad part about this is that Nintendo really got lazy while coding this. Since so much is done in this update, many are finding that their Wii freezes part of the way through the update. Unfortunately for some, just like with the XBOX360 update last month, if the freeze or error occurs while it’s writing to a critical part of the firmware it will brick your console. The vast majority of Wiis bricked by this update had never even had homebrew run on them.
Even the new bootcode is so buggy that the updated homebrew bootloader isn’t even based on Nintendo’s code anymore. They wrote their own.
With this update completely negated by the homebrew community in less than 36 hours I imagine Nintendo will either get extremely crafty with their next update or simply quit trying.
