Use the force? IOS249?

I've got Call of Duty burned to a DVD and the disk asks me to system upgrade - I'm a little nervous to do this (my Wii has a Wassabi v2 chip).

I've also got the game on a hard drive, I've got Home Brew and USB Loader GX (ver 1.0). My Wii is running 4.3e.

Someone said I need to 'force ios 249' - is there a easy guide on how to do this?

I am a noob but can follow instructions...

Sounds like you need to update your softmod.
But to address your problem, you need to install
priiloader and block online and disc updates.

Thanks, I'll do the priiloader tonight.

I'm on USB Loader GX, v1.0 and the latest version is 2.3. Is there a way I can update using the Wii connected online?

Will I need to update anything on the SD card?
