Technical info
TypeSpecialized IOS
StatusActive


IOS15 was previously used by some official channels; it has not been stubbed because the Internet Channel, which could not be updated through standard updates, previously used it.

This IOS contains the NAND Boot Program; it seems to be a slightly modified version of v1.21 that patches the Internet Channel.

In the past, this IOS was often used by homebrew, as it is one of the only known IOSes that is safe to downgrade on RVL-CPU-20 Wiis. It was then used to patch the signing bug back into newer IOSes, like IOS36.

Titles using this IOS

None of the latest versions of these titles use IOS15.
