Hacking Some question about an originally Korean Wii (4.3U)

[Corredor]

First of all, sorry for my bad English. It's not my native language.

I have a Wii running System Menu 4.3U. I have checked some information about it through sysCheck v.2.1.0 HD Edition report. It was originally a Korean Wii: "Region: NTSC-U (original region: KOR)".

I'd like to update the Homebrew Channel to version 1.1.2 (currently, it's 1.1.0) and to install both cIOS 249 base 56 v10 beta53-alt and cIOS 250 base 57 v10 beta52, but I don't know if it's safe because there is already a cIOS in slot 250 and I don't know what was installed.

Wii Shop Channel version is 20 and it doesn't work: always report error 209600. Can I install a Wii Shop Channel version 21 (using YAWMM)? Will it work?

Final question: if I click on update button (after testing connection, for example) for some reason (it's just a hypothesis, I'd never do that), will my wii be bricked (003 error)? It's already on 4.3U, so is there any risk to be wrongly updated to System Menu 4.2?

Here is my sysCheck v.2.1.0 HD Edition report:

Thank you so much! I'd appreciate some additional advices to prevent bricking.

After reading a lot about how LetterBomb, Priiloader, IOS and cIOS work, I have decided that everthing was safe. First, I have updated the Homebrew Channel and then I have installed Priiloader 0.8.1. I have accessed Priiloader by holding reset button while booting and I have blocked updates online and by disc. So, I installedcIOS 249 base 56 v10 beta53-alt, cIOS 250 base 57 v10 beta52 and Hermes cIOS version 5. Finally, I installed Wii Shop Channel using MMM. Everthing is working now and I think I have a safe ex-Korean Wii.

Meep..
I'd pay a lot of money for a Korean Wi that works; I have one but it's Error 003'ed and I dont have the effort to fix it.
@Corredor would you consider selling it? c:
