| IOS15 | |
 | |
| Technical info | |
|---|---|
| Type | Specialized IOS |
| Status | Active |
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.
Some versions of IOS15 contain some Broadway code including the NAND Boot Program; the purpose of this code is unknown, but it is identical to IOS21.
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.
