Restoring another wii

My friends wii used to ahve homebrew until he updated to 4.1. Now none of the bannerbombs work and we definetly dont want to upgrade to 4.2. I made a backup using bootmii, and if i do update to 4.2, install bootmii, then restore using my backup, will that work or will it screw stuff up?

It won't screw stuff up if you do that. (AFAIK)

Updating to 4.2 officially will overwrite boot2, hence overwriting BootMii. If you use dop-IOS MOD, you should be able to update to 4.2 WITHOUT the boot2 update, meaning if something goes wrong, you'll still have BootMii. Seeing as you have BootMii, dop-IOS MOD is reasonanly safe, as if you brick, you can unbrick fairly easily.

I have bootmii installed as an IOS though. on IOS254

You can't restore anything if you only have the IOS version of BootMii installed.

he can but on the restoremii screen he has to press all four buttons (a,b,x,y) on the gamecube controller at the same time for it to work

Where the hay did you get that information?

a youtube video and a few posts on this forum (:

Its true, but its VERY dangerous. You should NEVER try it, because if something goes wrong during NAND restoration, theres a very signficant chance of a full brick.
