Well when homebrew first came out they patched IOS36 since Ninty originally gave permission to this IOS and then took it back following the circumstances it was being used for. Some homebrew still rely on a patched IOS36 which has all the privileges to downgrade or overwrite a Stub IOS (Stubs do nothing but take up space) or higher revision IOS. Eventually people started installing a patched version of IOS36 into the IOS236 slot with a max revision number, just in case you do an official update by accident that particular IOS will not be deleted. So know any IOS that has a higher revision will never be deleted by a lower revision IOS with a official update.

I will gladly link you to appropriate files

and guides

Use this as a reference when ever you need help with homebrew. It's a really great guide ---> http://gwht.wikidot.com/

You can find anything regarding CFG Loader, IOS236, IOS249/250, IOS202/222/223/224, etc. You can even learn how to FTP into your wii so you will never have to remove your SD card you can transfer files over WiFi or any Wireless Internet.

Make sure you have the "Homebrew Channel" installed which im sure you do

Typically you will need to a patched IOS36, if you are having problems patching this IOS you can always grab the IOS 236 installer here ---> http://sharebee.com/07d2cc92 (v5) if that one does not work try (v4) ---> http://sharebee.com/b1972991.

You should have IOS249/250 installed, if not grab the installer ---> http://goo.gl/Or6bz you should use base IOS 57. Depending if you want to load VC & WiiWare titles from you HDD you install IOS249 using rev 17 here first ---> http://goo.gl/puFM8 you have 2 options to download this file. Choose one.

You can grab the latest version of Dop-Mii Wiibrew Edition v14.5 here ---> http://goo.gl/RxT06 or an older version 13 here ---> http://goo.gl/QTbGi ignore the warming and download anyways.

You should be able to us v13 and reload IOS236 or 250 to install a patched version of IOS36. You might ask yourself why do i need a patched IOS36 when IOS236 is suppose to take it's place considering it's the same IOS installed in a different slot? Well the answer is some Homebrew still requires it like Priiloader
smile.gif
and IOS236 is like a safefail you will never lose it due to it's high Revision number
smile.gif


If you want to use the latest version v14.5 use the IOS58+ method if you don't have IOS58 yet use this installer to grab it ---> http://goo.gl/RqjR you could use Dop-Mii to install IOS58 but im trying to make this as noob friendly as possible as i know how i was in the beginning
smile.gif


If your Homebrew Channel is not using IOS58 please reinstall it using the hackmiiinstaller here ---> http://goo.gl/TddQ. Better homebrew compatibility with USB 2.0
smile.gif


Have you installed BootMii? if not you should. Have you installed Priiloader? if not you should.

Now that you should have IOS36(Patched)~IOS236~IOS249~IOS250. you can now use any of the above methods to install IOS21:)

The thing about IOS249rev17 is simply the last rev that supports Triiforce (VC~WiiWare Emulator) and can essentially load these Games through a USB Loader you can find the guide here ---> http://goo.gl/V7oUf this is a quick simple guide
smile.gif
just have IOS249rev17 installed and use IOS222 to load up VC/WiiWare titles. You can still have the latest IOS250 which is rev20b.

The reason you load these titles up by 222 is that they are on a FAT32 formatted drive. (if your using a WBFS formatted driver swap ASAP!) And rev17 is needed to load the Triiforce Emulator. It's like a shortcut you see the title in your USB Loader and you click on it as long as it's loading the game with IOS222 your good cause it's using IOS249 rev17 to load up Triiforce and then IOS222 to load the game. While IOS250 is used for other Wii games.

LoL alot of info i hope this all helps.

i think i have ios236 patched....it was included in modmii...

Sounds like your burying yourself into a deep hole of confusion and bricked Wiis. I would just ignore IOS 21, and go about your business. It is not required.

okay assuming i don't need ios21 this still doesn't explain why my nand back up didn't work...:S
Did you even make a proper nand back up to begin with, you said it failed the first time. Do you understand what a nand back up is exactly? The Wii has an internal flash chip that is 512mb in size, in laymans terms this is the Wiis C: Drive, it stores all the necessary system files and the game saves etc. You use Bootmii to create a bit-for-bit backup of this, onto an SD card. Using that logic you must have atleast 512mb clear on your SD card. If not you will get an error. I would recommend backing everything thats on your SD card to your computer, use your computer to format it to FAT, then copy back the neccisary files leaving atleast 512mb of open space. Run bootmii and create a proper backup, once that is done go back to your PC and copy the nand backup to a safe location on your PC, remember this location because in the future you might need to use it for brick recovery (however, as long as you do things in a logical and thought out manner, and dont blindly go deleting things, you will never ever need this nand backup, but its just safe to have it). Again, just ignore IOS21 and follow the rest of the guide. THIS IS NOT ROCKET SCIENCE!

Code:
1022: Wad Install Error: Most likely incorrect format or corrupt SD card. Memory might be full.
Try using another sd card, or performing a fresh format of it and try again.

IOS21 "Contains NAND BOOT PROGRAM", so that may explain why u are having problems backing up your nand. TBH, I didn't think IOS21 was required to back up the nand... but maybe it is, I'm not sure.

Okay, so why are you trying to back it up now? Just to see if you can do it? You do realize it will revert any changes youve made since you created the backup to begin with?

Because IOS21 isn't required to make the NAND backup.
From Wiibrew:
QUOTE
BootMii is a system designed by Team Twiizers to enable complete low-level control of the Wii. It allows the Wii to be controlled mere moments after the On button has been pressed, before any IOS has been loaded and before the NAND filesystem has been read.

If it is required then just download the latest revision with NUSD, pack as wad, then use an older version of Wad Manager to install it, if you still get errors try using a diffrent base IOS to install from (i.e. if the default 249 returns the 1021 error, then try installing it with IOS202 or IOS36).

SysCheck is buggy, and doesnt always work. I recently modded a friends black Wii that had 4.2u installed, but it kept hanging on trying to find the right TMD filesize for ios80 (which is the 4.3u system menu lol). If it crashes then no big deal. If you really really want to run syscheck then try using an older version.

actually sysCheck worked on the new wii that i modded...everything was up to date...hbc 1.08...but on an older wii the hbc was quite out dated...there was no version number but it stated beta 8...it didn't show which ios it was using either...
