Really don't up date to System Menu 3.4
They changed alot of things to try and stop people from running Backup Loader, The Homebrew Channel and other great apps. Its still possible to mod it but it just take a little more effort compared to later versions.
Nintendos new Policy
"To ensure that your Wii Console is operating properly and efficiently, we may download updates, patches, upgrades and similar software to your Wii Console. In addition, we may disable unauthorized or illegal software that has been placed on your Wii Console without notifying you where necessary, in order to comply with applicable laws, assist law enforcement, protect us and our customers, and prevent the use and distribution of software obtained through improper channels." But if you've modded your Wii and updated all your channels will still be their but, theirs a slight chance Nintendo Wii24Connect will kick up and erase all you Channels.
BUT to stop this, simply turn off your Wii24Connect
