Why is my WII doing wrong dumps ?

[RiMMER]

Hello there, everyone!

Everytime I dump a GC disc on my WII, it's simply messed up. If I'm not mistaken, the dumps is 99% correct, only like the first 1% is kinda not good, something around boot sectors maybe? Those are always different when I compare the dump to a redump verified dump ...

Have anyone gotten to something like this? Can anyone explain it? Or is my WII simply messed up and I should buy a new one ?

EDIT: And hey, maybe it'd be great if someone wrote a GC games / WII dumping guide ? Or am I to understand that the sticky one in this forum is the best we can get? :>

have you read the guide properly?

3. If you have cIOS v1.4 or v1.5 uninstall it with the unistaller and then install v1.3b to have a clean system. Don't use IOS249 v1.4 or v1.5 because it has a bug which cannot read last sector of first layer of Wii dvds (not confirmed: please beware some modchips cannot retrieve right dumps of Wii dvds even with v1.3b or lower)

it appears that you have the above mentioned problem... is your Wii modded?
i use superdump and haven't had any problems with it... so glad i could finally pack away my gc broadband adapter and phantasy star online as super dump is way faster

if i was you i'd try uninstalling cIOS 1.4 or 1.5 and then installing 1.3b, according to the guide that should fix the problem...
note: just to be on the safe side, i suggest you install bootmii as boot2 and dump your NAND before you do anything

Do you dump by WiFi or by USB ?

I never tried to dump from my Wii because I have my GameCube modded, but I'll try this tomorrow in order to check if the Wii is less stable than the GameCube or not when dumping!

I think the sticky guide is the best you can get around  , the only thing omissed is "how to softmode your Wii" (I don't add this stuff because it can be found in every Wii hacking website and because I'd have to add some files that could be considered illegal).
At 99,99% your problem is what was quoted by Pikmin.

You don't need to do that, just overwrite the currently installed cIOS with 13b (not 1.x). Never delete any IOS, always overwrite them, it's a lot safer.
After you dump, you can go back to rev 14, 15 or 16.

That's wrong. I know you can make mistakes unistalling iOS, but many people had problems downgrading iOS without disinstalling old one.

Who said anything about downgrading a IOS? Read carefully.
I was talking about downgrading a cIOS, which is completely different.
There may be cases where after uninstalling the cIOS you'd have to softmod your Wii all over again since you wouldn't have a hacked IOS to install stuff. So it's not recommended to do that.
But even if you want to "clean" your Wii (e.g. when you have CIOSCORP installed) it's always recommended to overwrite the IOS's (with non stub versions, of course), uninstalling some IOS's could lead to a really bad brick.

I meant cIOS38 (IOS249), I never read about any wii brick problem on downgrading this IOS (there's a tool in the package in my guide). You can only brick your wii if you install cIOS38 with a clean IOS36 or maybe if you install it using a different IOS than 36, but this could happen even if you overwrite it.
Moreover installing cIOS38 is the last step you have to do for a standard mod, so what can be affected?

Steps for a Wii mod :

1) Installing BootMii + HBC
2) Backup Nand
3) Downgrade IOS15
4) Patching IOS36
5) Installing cIOS38 (+ preloader if you cannot install BootMii as boot2)

Everything else is not needed.

I don't know if you can get problems if you have a lot of shit installed after cIOS38, like CIOSCORP or other HB IOS, but these are not recommanded in most of places. Those IOS aren't necessary for dumping and are not reported in any modding guide.
Maybe you meant downgrading official IOSes and System Menu? This is clearly very dangerous!

Of course not, that's exactly what I said in my previous post. Install cIOS rev 13b (IOS 249) over the currently installed cIOS rev 14/15/16 (also IOS 249). After you dump the game just reinstall cIOS 14/15/16 (IOS 249) over the currently installed cIOS rev 13b. There won't be any brick with this procedure and you won't need to uninstall anything.

You can only brick your wii if you install cIOS38 with a clean IOS36 or maybe if you install it using a different IOS than 36, but this could happen even if you overwrite it.

LOL, you won't be even able to install the cIOS if you don't have a vulnerable IOS. That's exactly why you use TBR.

Rocknroms, by what you wrote, I think you understand what I posted earlier (install a cIOS over another one). You probably just didn't read it correctly

[Rocknroms]

I understood what you wrote in first post, but as I said it's better to delete cIOS (rev. 14/15/16 **) and then install rev.13b. Again, it cannot damage anything in your system (even if you got a brick, which never happened as long as I know, you can still start wii via bootmii or preloader and fix everything), but some people have problems with superdump and a downgrading cIOS (for example I had problem the first time). So, as I never hear about bricking for unistalling and reistalling cIOS, I don't understand the real meaning of your first post. If you have prooves that a cIOS uninstall will brick your wii, please post them and I'll edit the guide.

** I didn't test yet the new rev.16.
