 + **Do NOT use a Nintendo Wi-Fi Connection service unless it is known to be RCE patched (such as [Wiimmfi](wiimmfi)). Doing otherwise could allow a malicious actor to BRICK your Wii!**
 + **Only install updates for your own region!**.
     + Installing updates from another region could have no effect at best, but result in a [Korean Kii/Error 003](bricks#korean-kiierror-003-brick) brick at worst. To prevent this from happening if you bought a pre-owned Wii, run [SysCheck](syscheck) to verify the original region of your console. If it is Korean, be EXTREMELY careful with applying system updates to your console, and consider seeking support for further assistance.
-+ **Do NOT delete or modify system files, and do NOT install any system file mods unless you know what you are doing!**
++ **Do NOT delete or modify system files, install old versions of your Wii Menu or IOS, and do NOT install any system file mods unless you know what you are doing!**
     + An example of modifying files going wrong is replacing IOS80 on Wii mini, which may result in a [Wi-Fi Brick](bricks#wi-fi-brick).
 + **Do NOT install homebrew from untrustworthy sources or if the source code is not available.**
 	+ Software on the [Open Shop Channel](osc) is safe.
