Hacking Hykem's 5.5 iosu Exploit

[oumoumad]

I really hope we get an announcement on 5.5.1 . I kinda want to update some of my games, but I'll wait for an announcement first.

Don't get me wrong, the rule is to never update. See those who were on 5.4.0 and updated to 5.5.0 now the 5.4.0 have all access to homebrew thanks to the mp4 exploit.
But yeah, it depends what you want more, eshop access or sooner homebrew access.

Unless Hykem has a totally different entry point than stagefright .

He said it was stagefright already:

Yes. People are confusing this a lot. The final goal is to make a joint release for the latest firmware.
That will be a browser exploit as entry point (based on the Stagefright bug), a PPC kernel exploit (not necessarily the one we currently have, we are always looking for new ones) and an IOSU exploit (the bug I'm currently attempting to exploit should work up to 5.5.0).
The IOSU part will probably be obfuscated to delay patching.

Ok, your hope is narrowed those on 5.5.1... unless Hykem found other entrypoints in the last couple months, I no think you'll have access to a hack on 5.5.1 soon.

Does the IOSU will permit downgrade to the initial factory version of a Wii U?

It's best that way, hope should not be had for those on 5.5.1 that will only lead to more disappointment. It's best anyone on 5.5.1 doesn't update any further and play the waiting game without any expectations.

First post here but thank you for this. I made an account the other day just so I could make a post like this but decided against it to keep drama down. I have never seen more self entitled, immature bs anywhere else like what I see here on a daily basis. Hopefully someone puts it to a stop soon.

Threads must stick to topics? Might want to check threads more often with that statement.

To anyone who answer:

What happen when a new game using a higher firmware appears? Can a new game use libraries only available on higher FW? I'm asking here cause someone said the exploit would allow to downgrade.

Another: Somewhere I read the Wii had a way to go online even with a custom firmware and all that, and in another place I read someone got banned for using that trick and when called Nintendo, they said he/she had "something" installed (the HBC). Again, will this exploit allow for online features?

It is too much for the mods to check it constantly, just report it.. it works better than complaining about it .. i know.

IOSU will allow online-play, you won't get banned though unless you use cheats. (Of course we can't say with a 100% certainty but it works that way on 3DS and to my knowledge this is not diffrent for Wii U)
Downgrading is absolutely useless when we have IOSU because we have everything you can get on older FWs and the latest libraries. A new game can however use newer libraries than are in 5.5.0 (if an update with new libraries is going to be released 5.5.1 is not that update) but due to IOSU allowing emuNAND this can be upgraded to the latest version with the latest libraries without losing 5.5.0 (and this IOSU) on sysNAND.

Could u still get emuNand if we still need to use the userland exploit to load iosu every reboot or do we need what he was looking for a boot exploit?

Yes, much like the 3DS which used to not be able to auto-boot into emuNAND will also work, but due to the fact IOSU is still not released Hykem is either still looking into the boot exploit or is finalizing it, as he said in his post that he would release IOSU immediately if the boot exploit wouldn't work out.

Quotes speak louder than words:

So, I've got good news and bad news.
The bad news is that I'm going to postpone the release again. I said this week would be a more realistic release date, but I never confirmed it would happen then. Still, it's not a huge delay and it's definitely not to wait for a new firmware update.
Like I stated before, I have the entire month of January free just to work on this and the exploit will be released and maintained before February (yes, I'm sure of that).
Now the good news, which should explain the additional delay. I need some time to pursue something I found in the MCP module. If I'm correct about this, we should be able to get a boot-time exploit. The reason for that is that the MCP module is responsible for launching "master" titles (like the PPC kernel, for example) and I found a bug that, if it turns out to be exploitable, should allow to hijack execution while MCP is still preparing to launch stuff. This means, early IOSU access and a direct boot into an exploitable environment. Not to mention that MCP is the IOSU user module with most privileges (next to BSP that is) and having access to it alone is more than enough to own the IOSU kernel at any given time.
I believe it's important to look into this because if it works, no one will have to worry about possibly bricking consoles by installing custom titles (homebrew channel, for example) and then attempting to launch them before triggering the exploit again after a fresh boot.

With that said, if this turns out to be nothing, I'll release the exploit right away.

Take your time @Hykem .

Looking forward to the release.

IDK if this has been asked yet but um... has anyone heard from Hykem in the last week or so? Twitter seems to be dead and his profile says he was last here on the 2nd.

Everyone is asking the same question mate. Hykem seems to be the lonewolf type and only comes online when he needs to.

on the 11th day of Hykem's Disappearance, the other dev gave to us

• One 5.5.0 user land exploit
• 5.4.0 home-brew support
• and less hope that Hykem's IOSU exploit is coming

Maybe you should ADD a countdown timer in your SIG..
