VashTS said:it will remove your softmods. don't update, install priiloader and enable block disc updates. or optionally update all of your ios.
probably not a brick risk, but it is unnecessary to update through the disc.
Satangel said:It all depends on whether it's an actual firmware update, or just a squad update.
From what I can make out of your post, you are already playing PES 2011 and you want to play it online now. So if it asks for an update when you try to go online, it's probably a squad update, meaning it will do no harm at all.
VashTS said:oops my mistake. i didn't realize you said you wanted to go online.
as far as every prior wii game, updates from online are just that. there is no risk of bricking as it only adds a save file. harmless, even if for a different region. so yeah go ahead its fine, as long as you are not updating the system there is no risk. and if you are playing the game, then everything should be fine.
it may need the shop channel and corresponding ios updated. i know black ops had me do that.
