Here's a list of things you should and should not do once you've modded your Wii, to make sure you don't brick it.
- **DO** make sure you've installed [BootMii](/bootmii) and [Priiloader](/priiloader) to make sure you don't brick your Wii.
- **DO** make backups of your Wii NAND regularly with [BootMii](/bootmii).
- **DO** install Wii Menu themes if you wish, but only use [our tutorial for it](/themes) carefully. Other tutorials aren't guaranteed to work properly.
- **DO NOT** install WADs of random IOS, older versions of the Wii Menu, etc. unless you know what you're doing, especially not on vWii or a Wii Mini.
- **DO NOT** or use old versions of Wii homebrew. If you follow Wii modding tutorials from the Internet, be cautious about using old tutorials (likely pre-2012), especially if they have to do with things such as IOS.
- **DO NOT** modify, rename, or delete random files on your Wii NAND unless you know what you are doing.
- **DO NOT** use the homebrew app "KoreanKii" on a non-Korean Wii.
- **DO NOT** Install **any** IOS or Wii System Menu on a Wii mini other than [d2xl cIOS](/cios-mini). Doing so **will** brick your console if a Wifi card is not soldered to it.
- **DO NOT** use any Nintendo Wi-Fi Connection replacement on your Wii except for [Wiimmfi](/wiimmfi). Unfortunately, other replacement servers are vulnerable to an exploit that can brick your Wii if you use them. [RiiConnect24](/riiconnect24) is safe to use as well.
If you follow these guidelines, you won't have to worry about bricking your Wii. Wii modding is safe, and bricks usually occur due to something done by the user that is on this list.
Continue to installing cIOS<br>
cIOS are used to play games with a USB Loader. It's also useful for many other homebrew apps.
