Here is the real NOOB guide,

Requirements

a. A wii ready to be hacked. Game says it requires a nunchuk though it's possible to use only directional keys of wiimote.
b. A Lego Indiana Jones game (If you have a chipped wii a backup will do too)
c. A compatible sd card formatted to FAT (a Sandisk 2GB SD card will do the job.)


HERE'S HOW YOU DO IT

We got 3 zip files, for each video we need to empty our sd card and copy the files included in the zip file in order. If you've never played Lego Indiana Jones then you should just open it once at least so that you can copy hacked save file over to the wii. If you have a previous save file you want to keep then just copy it over to your sd card and back it up... Then delete the save in your wii.

The guide doesn't cover Homebrew Channel installation or downgrade. I recommend waiting for the Homebrew Channel release and installing it then.

For the needed files ask nearest provider (send an email to wiidewiiauto at google's thing)

1. Step - Installation of IOS 41

First of : Empty your sd card and extract the contents of 4.3-Step1.zip file. Insert the sd card into your wii. Then follow the guide in the video




2. Step - IOS 15 Downgrade / 3. Step - Patched IOS 36 Installation

First of : Empty your sd card and extract the contents of 4.3-Step2-3.zip file. Insert the sd card into your wii. Then follow the guide in the video



Take Note : You might get codedumps when you select IOS 15 in the 3. Step. Just retry that step until you successfully get through it, eventually it will reload into IOS 15 successfully... While taking the video it worked for me in the first try, people got varying results some retrying only once or twice but some needed to retry more than twice...


4. Step - Cios / Usb Loader installation

First of : Empty your sd card and extract the contents of 4.3-Step4.zip file. Insert the sd card into your wii. Then follow the guide in the video






If you do own a ntsc copy of Super Smash Bras Brawl and you are on 4.3U then you can use that game too... You just need to do the exploit stuff with SSBB game using Smash Stack exploit. With SSBB you need to use a non sdhc card since game doesn't support sdhc cards.


To prepare for this : First delete all your custom stages.
For each part (video) : Extract Smash Stack exploit to your sd card as well..
Whenever you see Indiana Pwns exploit : Use SmashStack exploit. To do so, just launch SSBB and go to Stage Builder.

You can download and get more information about Smash Stack exploit

--- Old post explaining the core hack for the experienced people ---

Do not attempt before awaiting confirmation from a few people who are protected with bootmii!
It's confirmed working with no after-effects, so you can go ahead if you are not too noob

1. Grab WiiPower's latest TBR (1.13) from wiibrew which contains latest revision numbers (http://www.mediafire.com/?qzmqirhnuyz)
2. Download lowest revision of IOS 41 from NUS using NUSD (such as v2835)
3. Install IOS 41 using wad manager, it's a ninty signed IOS and it will gracefully install with non-trucha IOS
4. Use WiiPower's TBR to downgrade IOS 15 as usual... just select the IOS to be used as 41..
5. After downgrade, patch and install IOS 36 as usual...
6. Get rid of Korean IOS 41...
7. Do whatever you do with your trucha enabled IOS 36 ;p

ps1: TBR might codedump on selecting IOS 15, retry in case... I had modified da_letter_a's mod but I got all kinds of problems with the console code so I can't release it ATM.
ps2: Use the usual exploits such as SmashStack or Indiana Pawns to run TBR... Indiana Pwns doesn't boot dol files so it would be a good idea to boot loadmii which is said to be distributed in elf executable format.
ps3: If you are noob, do not attempt to do this, just wait TT to release new bootmii
ps4: The essence of this workaround is the fact that we (non korean wii owners) don't have korean ios but we can install any revision of them and use, one area Nintendo just neglected I guess..
