damysteryman has updated its special version of the IOS 236 Installer for vWii. This version of the IOS patches 36 now with the latest patches vWii so that programs such as the FS Toolbox should no longer issue the error -1029.
The IOS 236 is a copy of a patched IOS 36, which allows even programs without support HW_AHBPROT gain root privileges.
You'll need to dump IOS36-64-v3864.wad from your vWii and put it on the root of the SD card. You can do so with a tool called Blue Dump. As it cannot be downloaded from NUS.
