Hacking Downgrading IOS 15 on 4.3 Virgin wii

[WiiCrazy]

Well, if you have a "new" Wii, it might be really IOS related, as we know that the "LU64+" Wiis can't load IOS36v1042 due to some timings. Maybe it's the same with IOS15v257, just that this works 1 out of 10 times. But my main suspect is still libogc. The IOS Reload code was changed when the timing stuff on the "LU64+" Wiis was discovered, and maybe its intention was to load IOS36v1042 on these Wiis. Anyways, at this time the IOS Reload code was broken, and it seemed fixed to me in 1.8.x. But i always load module based IOS and cIOS, so ... i'm repeating myself, i think you get it and i can stop

Nopez I have a quite an old wii.. Indeed adding some sleep after reloading IOS 15 helps it... just test it with yours compiled with 1.8... add sleep(1) after reloading code.

Where do people get this idea that the sysmenu's IOS needs to be patched to play warezed wiiware/VC from the SD card? It's wrong - unless whoever made the .wad did a shitty job and fakesigned the TMD for no good reason. Only the ticket needs fakesigning and it's not checked when loading a title from SD.

That was the information on all Wii forums when SM 4.0 came out and introduced the Move to SD feature and the SD menu.

I will try to install a standard no-patched IOS 60 on my Wii tonight and check if it is needed or not.

I installed a standard no-patched IOS60 and you are right, I can launch Wiiware/VC from the SD card even though it was installed with WAD Manager. However homebrew channels (like forwarders) moved to the SD card didn't launch. They worked again as soon as I trucha patched IOS60 again.

Right, homebrew channels will have a fakesigned TMD but wiiware/VC doesn't unless a bad wadpacker was used. So there are lots of people pointlessly modifying their system menu's IOS, better hope nintendo never implements runtime sig checking.

Btw, I've put some videos to demonstrate the hack.

ps: meh, 4 Indiana Pwns boot... this could have been 1 or 2 if loadmii behaved... still it's straight forward and not so messy... no gc controller tinkering / no config tweaking...

url where the videos are, so we can see them

Just look at the initial post.

anything like wiiware/vc that is signed with your console key has to be fakesigned or it won't run from the system menu.

@Wiicrazy: In the last video you write that it is possible to downgrade by installing IOS70 first and then SM 4.1 but SM 4.1 uses IOS60. Just mentioning it so that people don't brick their Wii's.

Actually I packed the minimum required files and they are available... hints are in the first post.

In step 4, before you install those wads, wouldn't it be easier to install priiloader, install the hacks for 4.3, then reinstall HBC? Does restoring and older IOS 34 prevent HBC from being deleted?

 

[goku1980]

My fault I just didn't see it , lol. But it still was easy useing this method.

A new HBC will be released and you'll be installing the new version anyway. If you want homebrew channel and so on it's better to go back to 4.2 in step 4... I've literally put described 4.1 downgrade in the video.. I should change it to 4.2 since update from a game disc in that state will brick the wii (4.3 stubs IOS 70 which is used by 4.2)

ps: To downgrade to 4.1, install non stub IOS 60 and IOS 70, then install 4.1 menu..
ps: To downgrade to 4.2, install non stub IOS 70, then install 4.2 menu..

Added a poll, please contribute if you've followed the guide..

Hey If we have LoadMii as either a App/Channel then what's the point of the Hombrew Channel then?? lol Since they both pretty much do the samething!! lol

Most people should like to use HBC much better than LoadMii ...........
especially it's interface/layout/user-friendly ..........

Also, since it uses the loader area like System Menu it has the best compatibility... But the point is, a new version of HBC will be released with a new title id... A new priiloader to support that hardcoded title id... all usb loaders will change the hardcoded id they use and so on... There's not much reason to do installation of priiloader / homebrew channel / bootmii and so on twice...

That's my thinking though, it's not that hard to install HBC and so on after you've hacked your wii with this method anyway...
