Hi There! I'm wondering if someone can help me solving some doubts I have about the cios, hermes cios and trucha ios.
I want to update my wii cios because wiiflow is not working very well. Now I think the problem are my cios because a friend modded my Wii in 2014, and since then I haven't update them. I use syscheck to see what cios I got:

Now I want to update the cios with dx2-cios but, is there any problem If I overwrite the hermes cios? and what about the ones that are bug trucha, and the stub?

Hello.

The d2x cIOS Installer should be used to install d2x v6/v7/v8/v10 Versions to the recommended Slots (248)/249/250/251.
Other Slots like for the hermes (reserved) used 202/222/223/224 is not recommended.

I hope this helps you.

Good Luck and
Thank you.

P.S.

If you like to know how this works (highly recommended) please read the (actual) Guide from Cyan:

Just use ModMii. You can even open your syscheck with modmii and it will tell you what you should do

Thanks a lot for the link d(-_^), But..., what about the IOS with bug trucha? As far as I know the bug trucha is to hack succesfully the Wii. Is there any problem If I overwrite them with d2x Installer?

From Cyan´s Wii Hacking Explanation Guide

Trucha bug and IOS236

Trucha bug

If you want to learn how signature are working, you can read the next big chapter (Security and cryptology), but it's not necessary to understand how Trucha bug is working. You can skip it completely as it can be hard to understand for end users.

Trucha bug is one of the first vulnerability found in the Wii security system and is still used today.
Trucha bug is related to the signature checking process. All the IOS had this bug up until 2008. The first released IOS without this vulnerability was IOS37, at the same time Nintendo patched the bug in all previously released IOS.

This bug lets users abuse the IOS's signature verification method to always answer "good" even if the signature is wrong, allowing the program currently running on the PPC CPU to continue its execution instead of terminating.
Applications taking advantage of this bug are Disc channel, Title installers (Wad manager, IOS installer) and indirectly the System menu 4.x (for its SD menu).

IOS236

When nintendo patched the signature bug in existing IOS, hackers decided to "unpatch" one of the IOS to restore the bug. IOS36 was chosen and tools like "IOS36 bug restorer" or "IOS236 installer" were created.

To preserve the compatibility with official games which still uses IOS36 and keep this IOS36 legit (unpatched), the patched IOS36 result was installed into another, unused slot: Slot 236.


This is what you should understand: The slot 236 contains a copy of the IOS program located in slot 36, but this copy has the signature check bug restored (patched back).
It's commonly said "IOS236 is based on IOS36".
You can also see the format "Slot[base]" like this : IOS236[36], which means the same thing, slot IOS236 contains an IOS program based on a copy of the official IOS located in slot 36.

Why slot 236?
Noticing Nintendo always released IOS in lower slot numbers and in incremental order, it was thought a good idea to install patched, unofficial, IOS in reversed order from the available slot range (from 255 back to 0).
The 200 mark was far away enough from the official IOS to consider the above slots safe to use for hacks without conflicting with Nintendo's legit IOS. As a fact, Nintendo's highest ever used slot is slot 80.

By common usage, or untold convention from hackers, all hacked and patched IOS were therefore installed in the slot range from 200 to 255.

You can use the d2X cIOs Installer to install the needed cIOSes into Slot 249/250 for a proper Work of the USBLoaders.

Thank you.

Maybe I should add an explanation that it's not because it's called "bug" that it's a bad thing.
it's a bug in the nintendo's old code, which is what you want as it specifically allowed Wii hacking. seeing "trucha bug" in all your syscheck report, you are not the first user to be worried thinking that something is wrong.
