Sincerely, this community is lucky to have people like Cyan.
Shouldn't you be able to still install bootmii as long as you have the vulnerable boot1, even if you did those updates?No my boot2 was over-written by a game update long before I hacked my Wii unfortunately.
I'm not sure to understand correctly.
I'll tell you what I think should be done.
First, you can keep the full channel installed, it will not conflict with other boot method. But if you don't want it anymore because of the outdated state, you can remove it.
Removing the UNLR Full channel:
1. use a WAD manager to install again the channel (as you said you have left data of the channel, it's best to install it fully again so the channel is correctly installed)
2. use a WAD manager again, but this time when you select the .wad file select "uninstall" instead of "install". it will delete the data on your NAND corresponding to that .wad file
installing the Forwarder Channel:
1. use a WAD manager to install the UNEO forwarder v5.1
both channels (full and forwarder) are available on the googlecode download page (as stand alone, or in the full all-in-one package). They can be installed together without problem (but you will have difficulty to know which channel is the full or the forwarder, unless you launch them, and remember the position on the system menu)
The Forwarder channel will launch the boot.dol located on SD or USB.
To exit games to the loader instead of the system menu, you can set this:
In USBLoaderGX settings > Loader settings > Return to > USBLoaderGX (UNEO)
Do not install the USBLoaderGX's boot.dol into priiloader, instead you need to install the USBLoaderGX Forwarder's boot.dol (that file is located in the "all-in-one package" on the download page of the loader, inside the wad folder)
For the cIOS d2x, you can use v10, but just do not use the "alt" version if your drive don't like the alternative one.
Hermes cIOS v4+ allows you to use both ports too. if Wiixplorer let you select the IOS, use one of hermes IOS.
else, you can always install both d2x v8 and v10 alt in different slots.
The Wii is booting with IOS80 (if you are on system menu 4.3)So if I wanted to install v10-alt in a different slot, leaving v8 in 249/250 how would I do that? I presume the Wii would still boot using 249/250 so USB Loader GX would still find the HDD OK?
