I updated to 3.3U last November by accident so I want to downgrade to 3.2. I don't have wi-fi so I'm downgrading manually
offline. Alot of people say to update but I don't like how +3.2 auto-connects to the internet. Just my personal preference, so I want my 3.2 back.

I've pieced together how to do it but I have one step I still need help with.

After first installing IOS16-64-v257-prod.wad most guides say to install cIOS_fix.wad....but then after some more digging I saw that more people thought installing cIOS36rev7 instead was smarter. There's some conflicting advice over cIOS249 vs. IOS249. Some guides/posts treat them as interchangable while others said something like IOS36 installs to IOS249. Or they said install IOS36 first then IOS249. 'Readme' files that come with the cIOS36 said 36 installs as 249. But then they mix 'cios' with 'IOS' alot.

Bunch of questions relating this prob:

A) If I see a file that says cIOS36rev7 or cIOS249 v7 are those the exact same file serving the same purpose?

B) cIOS vs IOS confussion: I have a downloaded folder where the file itself is called 'IOS36' but the 'Read Me' next to it says it's a 'cIOS'. I assumed that meant these are cIOS's but the file names themselves won't say "cIOS" because they're not installed like that. But then I have another folder that has a filename of 'cIOS249-v5.wad' (fakesigned wadfile) which makes me wonder if my cIOS36 is acctually suppossed to called cIOS or not. ??? (I know the actual different between them but don't know how they are supposed to be named or tell them apart)

C) Even after I install cIOS36, assuming it turns into IOS249, does it still make sense to install unaltered IOS36? Some guides say I need the actual IOS36.

D) I've read that cIOS36 version 9+ has compatibility with USB loaders which I'd rather use but all the guides on downgrading to 3.2 use v7. Would that just be because that was the most recent version at the time the guides where written or is cIOS36 v7 the only version that compatible with a 3.2 downgrade?

End of questions**********

Like I said I'm asking about that one step in the downgrade, I know your not supposed to ask a million things in one post, but just so people know my whole procedure here is the larger plan of what I'm trying to pull off.:

Offline downgrade to 3.2 from 3.3U:

Run wad man 1.3 and install:

IOS16-64-v257-prod.wad

Run custom wad man and install???:

cIOS249-v7.wad
or
IOS36-64-1042.wad (where the 'read me' says its a cIOS)


Run wan man 1.3 again:

IOS9-64-v516.wad
IOS17-64-v512.wad
IOS20-64-v12.wad
IOS21-64-v514.wad
IOS28-64-v1288.wad
IOS31-64-v1040.wad
IOS33-64-v1040.wad
IOS34-64-v1039.wad
IOS35-64-v1040.wad
IOS36-64-v1042.wad

IOS30-64-v1040.wad
SystemMenu-v289.wad

And I've backed up my NAND with bootmii as boot2 so if I brick I can recover. :) And I have Wiikey2 (FYI)

I'd say I'm still semi-noob so would appreciate any explanations of this. Thanks!

Internet settings are completely the same between 3.2 and up to 4.2 firmware. So downgrading because of this reason is pointless.

If your talking about the new user agreement that Nintendo can auto-update your system then that is pointless as well. If you have already agreed to the user agreement, then downgrading isn't going to change that. Also Nintendo has never auto-updated anyones system.

I would advise not to downgrade your system. Your really not getting any benefit from it. Most everything that works can work on 4.0, 4.1 and 4.2 firmware anyway.

More then likley yes. cIOS36rev7 is installed to IOS249 slot. So cIOS249v7 would more then likley be the same thing.

An IOS (an easy way to look at it) is Independent Operating system. Each IOS serves it own purpose.

Some are for games.
Some are for hardware
Some are for the system menu itself.

The IOS36 is probably a patched version of the official IOS36, which exploits the system to allow you to install cIOS36_rev7 to the IOS249 slot.

A cIOS is a custom IOS that has been changed to do something different that the official IOS can not do. cIOS36_rev7 is installed to the IOS249 slot. It is installed there because it is not in use by any Official IOS and the (coders of hacks) believe they never will.

As for your question. I would guess the patched IOS36 file is not titled cIOS36 because maybe they don't want the user to get the patched IOS36 and cIOS36_rev7 mixed up.

Restoring IOS36 to the official version is not really necessary. If you restore IOS36 to official then the Trucha Exploit no longer will be available to run anything. But again you can use IOS249 to do that now.

cIOS36 is really outdated now. They are up to cIOS38_rev14 (stable version) now. This is what you really need to be using.

I wouldn't go the route of downgrading. It isn't really necessary. I would also use updated versions of cIOS and exploits. You can use my guides in my sig to softmod. If you want to stay at 3.3 then follow the 4.1 softmod guide in my sig. You can do everything without WiFi except for Hermie's IOS222/223 and DOP-IOS. Those are not 100% mandatory anyway.

If you decied you want to update to 4.0, 4.1 or 4.2 you can use NUS that is included in the softmod and download 1 of the above firmware of your region and install it using WAD manager. Then start the softmod (make sure if you go to 4.2 you use the 4.2 softmod guide).

I know everyone urges upgrade but I'd like to follow through with this downgrade.

I think it's more of a downgrade, like your installing IOS36-64-v1042.wad from a later version as part of downgrading to 3.2. I dont' know the rules about linking to another site but Wiibrew's IOS history list .v1042 as having the Trucha bug available. Was that a slip on your part or is Trucha still lost by putting in the non-cIOS version? Should i just skip putting the downgraded 36 in or will that brick my Wii?

I guess I'm wondering if the cIOS goes to IOS249 then the official IOS36 doesn't replace that or over write it? I'm confused because they have the exact same file name ...there' both called "IOS36-64-v1042.wad"

Ok but what I'm asking is if I wanted to stick with cIOS36, if version 9 is not compatible for 3.2 downgrading which is what I want to try here. Or does it make no difference?

I'm assuming the cIOS36 wad is what allows all the other IOS's to be downgraded from the guides I've read...does this cIOS38_rev14 accomplish the same thing? Like I put that in and it goes to the 249 slot and I can use that in procedure above or no?

This is an outdated way of doing things. Your probably looking at an old guide from a year or so ago.

As well most games will probably give you an update prompt when playing from the disc channel.

An example....

From the start of IOS36 there have been 4 revisions...

IOS36-64-v1042
IOS36-64-v3090
IOS36-64-v3094
IOS36-64-v3351

If you have IOS36-64-v1042 installed and the game disc needs a higher revision of IOS36 to be installed then you will get a prompt to install the update.

What is the guide your trying to use?

You also said...

We urge to update because that is the better way to do it. So why go against what most people say to do?

cIOSes are modified versions of official Nintendo IOSes. And as to not write on top of the official ones they install as IOS249. IOS36-64-v1042 is an older official IOS used to re-gain the Trucha Bug--loophole that enables one to exploit their system. Customarily, cIOSes are followed by a revision number e.g. cIOS36 Rev12 or IOS36 Rev12, in which case both are one and the same.

It doesn't make a difference. Custom IOSes, as the name implies, are tweaked and are open to all firmwares. Higher revisions mean more compatibility with newer games.

cIOS38_rev14 is what's going to enable your Wii to book backup games and USB HDD loading.

I've noticed there's little patience for wanting to downgrade but...
if you could just amuse me here (I don't want to bulk up my thread with some long story on why, trust me).

I'm not sure if this confirms or corrects whether I should install the official IOS36-64-1042.wad after slotting the cIOS version to 249. I'm wondering if by 'used' you mean that the cIOS exploits the official IOS to get Trucha back, and that re-installing it would negate things OR if you mean that installing the official IOS36 after the cIOS is ok?? Confused on that point.

Is this completly seperate from my downgrading procedure?
Or could I use it in place of IOS36rev7(9) in my downgrade strategy above? The red text bottom of first post.

Do ALL cIOS's slot to 249?

Is cIOS38_rev14 only for if I update? As in I can't use more recent exploits from 3.2?



thanks for any feed back.

cIOS36_rev7 and cIOS38_rev14 both install to IOS249. cIOS38_rev14 is just the latest stable version of the custom IOS that installs to IOS249.

But again there is no logical reason to downgrade IOS to lower revisions. This will more then likely cause more problems for you. If you have a logical reason id love to hear it.

Staying at 3.3 firmware and downgrading the IOS revisions to me has no purpose

Some do downgrade to 3.2 firmware but even that is kind of pointless with the current state of homebrew at this time.

This may make more sense if you gave the link to the guide your using.

With you being on 3.3, I'm almost certain that you may already have IOS36-64-1042. It can be re-installed if need be.

All Waninkoko cIOS releases have been linked to IOS249. There are also 222/223 developed by Hermes. cIOS38 will work without regards to firmware. Its sole use is to be able to play backup games and enable USB hard drive ISO loading.

I second larry. It really is futile to downgrade to 3.2. The guide you are following may be one that's archaic--back in the days where people felt it was best downgrade to make other games work. You really are better off updating to cIOS38 Rev14.
