'''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 a copy of the [[NAND Boot Program]] with [[error 001]] code; the purpose of this is unclear, as IOS15 was not used by any discs. This was introduced in IOS15v258, built 6 minutes before IOS21v515, suggesting that there was a miscommunication regarding which [[IOS]] was supposed to receive this update, since [[IOS21]]'s hex ID is 1-15, which may be read as IOS15. This only added 624 bytes to IOS15 and 649 bytes to IOS21's [[Starlet]] binary, so it was probably a trivial change in the code to load content 3 of the current IOS instead of the boot content of the [[title]] being launched, and perfectly doable in 6 minutes.

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]].
