Oh boy... this wont start a three page arguement XD also does this mean we will have something similar to ARM9LoaderHax on the 3ds, but on Wii U? Or EmuNAND?
A9LH, as the name says, is an exploit in Arm9Loader - a component of the N3DS kernel* that uses common keys stored in the secret sector (slot0x11key95 for 8.1-9.5, key96 for 9.6+) to decrypt the rest of the firmware.
* yes, a9lh works by installing a n3ds kernel even on a o3ds
A9LH itself only exploits a bad decryption of said kernel accomplished by editing the secret sector. The OTP is only used to decrypt the secret sector for reading, edit it, and reencrypt it. (And indeed now there are otpless techniques too).
The WU certainly doesn't have arm9loader, so the OTP is not a guarantee of cfw on boot.
It however is the prime opportunity for common people to dump some keys at home...
Well, this is what was needed for A9LH on the 3DS, so it actually means quite a bit.
Exactly. On 3DS.
