Updating Wii with Homebrew (4.3u) — Brick Risk Extremely Low, But No Benefit

Extremely low risk of brick, but no benefit to updating.

Why It's Safe-ish

• 4.3u is the final official firmware. No further Nintendo updates exist.
• Homebrew (Homebrew Channel, BootMii, Priiloader) survives official updates if you have Priiloader installed (blocks disc/online updates).
• System Menu 4.3 doesn't add features; only patches exploits.

Why You Shouldn't Update

• Updates remove exploit vectors (e.g., Letterbomb, Bluebomb) — makes future modding harder.
• No new functionality.
• Risk (tiny): power loss during update = brick (fixable only with BootMii/boot2 or NAND programmer).

Best Practice

• Keep Priiloader "Block Online Updates" and "Block Disc Updates" ON.
• If you need Shop Channel / WiiConnect24 (dead anyway), use RiiConnect24 (homebrew patcher).
• Stay on 4.3u. It's the stable homebrew baseline.

If you accidentally update: Re-hack via wii.guide (Letterbomb/Bluebomb/str2hax still work on 4.3).
