Wii U Hack: Hykem’s IOSU exploit on 5.5.0 slightly delayed
We’ve mentioned before that Hykem has plans to release an IOSU exploit on Wii U for the latest Wii U firmware 5.5.0.
Hykem had warned that hitting the exact date of Christmas was a stretch, and today he confirmed on GBATemp that he will not be able to make it to that deadline.
Nevertheless, he is still working on the hack and expects to have a release ready sometimes next week:
So, my intention to release something exactly on Christmas is clearly not going to happen. I already knew it would be quite a stretch to get all the relevant stuff done by tomorrow, whence the warning that it was merely an intention.
Still, I’m steadily working on all that’s necessary for a proper release and I will be spending the first month of the next year doing maintenance and giving support related to the exploit.
By the way, this doesn’t mean it won’t happen at all, I’m just giving an heads up so no one gets their hopes high for a Christmas eve release. Next week or so is a more plausible release date.
IOSU Exploit – What will be possible?
Users on GBATemp have compiled a short list of what the IOSU exploit could enable on the Wii U:
- playing backup games from SD or USB (USB Loader GX like) without the need of hosting files
- importing/exporting savegames to SD and maybe USB
- importing/exporting Miis to SD and maybe USB
- disabling format warning when USB drive for vWii mode is connected when Wii U starts
- maybe disabling firmware updates
- any kind of homebrew (apps) like WiiMC (media center)
- emuNAND
- a homebrew channel
- use DLCs together with backups (like a fully unlocked Mario Kart 8 and so on)
- Wii games could be launched through Wii U mode as injected VCs so using vWii could become pointless
- launching Nintendont through Wii U mode to make it run in 1080p
Imagination’s the limit with this list at this point, and we can’t tell for sure what the hack enables until Hykems gives more details or releases it.

First 😉 XD
Yes? Maybe?
Who cares.
I bet CPUzX cares.
That’s cool. He should take his time and enjoy his holidays.
Thx for all your work and care for the wii U.
I think it would be better to release that exploit after the 4th January, when all the sale stuff is gone and done.
Merry Christmas and merry holidays to all. 8)
take your time man no rush i got plentty stuff keep me busy nohows. kind reminder everyone disable internet on wii u,in case nintendo gets hair up there sleeve from possibly knowing this news. 🙂 happy holidays gonna be glorius new years
I’m just wondering if this hack would let me change the Wii U region =[ I’m stuck with JP Wii U T_T
All I want to know of it will be able to play back up WII U GAMES and not just wii iso. Of so I’ll donate 100$
Donate your money to game developers, as well, thief.
Rly? *** @ GTFO!
That’s basically the whole point of this hack 😛 IOSU is the Wii U Side and IOS is vWii side
More than likely, Yes.
Nintendont at 1080p with wii u gamepad support would be a godsend.
I chose the perfect moment to get a wii u.
this sound so good! I would be happy just being able to play backups! Merry Christmas
I can wait, the hack is worthless with out software loaders for homebrews anyway.
Do we know if this requires Smash Brothers Wii U or any other title to load the hack?
I might have to ask for a last minute Christmas gift. Lol
This better not enable piracy. Those cheap pieces of *** can buy the damn game instead, games aren’t even expensive.
Hi Madfalcon,
Somehow, i share your point of view.
Nevertheless, i am not a hardcore gamer. I’ve used to play since i’m (maybe) 10 (late 80’s). By the way, it’s more than a game in the game but to play isos, backups and so on pirate bunch of stuff. I can not explian that….That’s why i’m waiting for the IOSU exploit to be reaveled soon….
(Late) Merry Xmas to you and all your family.
Got me 5.5.0 Wii U, now to play the waiting game.
Hi Wololo team,
i do apply for becoming one of those guest bloggers. Actually, i’m a french 42-years old physician, playing all day long and fancying hacking this or that.
Feel free to ask me what seem relevant and forgive my bad english (or excuse my french!!!).
Bye.
I just got a WiiU for chrismas so I learned alot how the hacking work and if there already homebrews.
Well, it seem we can only play iso (the feature I don’t care), and I tested Xenoblade Chronicle Online (the game I buyed), 1st online mission with real ppl was quick (less that 10 secondes) because a level 16 character was killing all the monsters in one shot. I wonder if it was a cheater (seem possible as tools already exist to hack the game…)
Well… Call Of Duty and Counter Strike gamers already make me sick and disgust me of online playing. Now, I this is clear that online playing just sucks. Pleople sucks.
Doesn’t the Wii U support HDDs better than the Wii? As in it actually has official support for HDDs where the Wii needed specific HDDs?
Common Hykem common!!! :p i cant wait for this im shitting myself lol
Thank you for your work!
I bought a Wii U yesterday… can this work with the 5.5.1 E firmware?
Could we launch Wii games? And Wii U games?
Will you make a Tuto?
Keep up with the good work o/
I got wii u yesterday, as soon I went on wifi it went straight to updating 5.5.1 without me knowing I thought it was updating a game lol. hope hykem can help us 5.5.1 users get our wii u games working on backup hdd! I love my wii doing this now want the wii u to do it, have saved our disks this way. keep up great work all people working on this!
