So, at this point there’s no guarantee this will be released exactly on December 24, but Hykem’s confirmed the exploit and his intent to meet this deadline. This probably means an option set by default to block auto updates and block specific Nintendo addresses such as nus.c.
LETTERBOMB WII EXPLOIT UPDATE

Note that unlike the stage builder exploit, this exploit will be tied to your Wii. Don't worry, you can still launch Project M using a different exploit known as LetterBomb. (in other words, the Wii U scene has several aces up its sleeves and won’t need to reveal all of them at once). Using LetterBomb to Launch Project M If your SD card is larger than 2GB, then the Stage Builder exploit will not work. His exploit does not require PPC Kernel access, which means kernel exploits won’t need to be revealed for this one to work. Hykem confirmed he compromised IOSU, and that his exploit works up to firmware 5.5.0. So yep, having compromised IOSU is a big deal. In particular, IOSU is responsible for security checks on the Wii U, verifying that you’re not trying to run unsigned code, etc.
LETTERBOMB WII EXPLOIT PSP
It’s what we could compare to the “native” world on the PS Vita per opposition to the PSP Emu. This exploit only works with any region of System Menu 4.3.

dol files can be found on the Homebrew applications page. Wait, what’s IOSU on the Wii U?Īlright, for those of us not familiar with Wii U hacking, IOSU is basicallly the operating system of the Wii U when it runs in Wii U mode. LetterBomb is achieved by use of the Wii Messageboard which executes a homebrew application from an external SD card. He’s clarified today on GBATemp that he has an exploit running on IOSU, up to firmware 5.5.0, the latest and greates Wii U Firmware.

Hykem, known for his hacking work on many, many consoles, just confirmed he’ll try to release a Christmas present for Wii U owners.
