IOS41 is a Korea-specific IOS used by preinstalled channels.

Between 4.2rev04 and 4.3rev03, this IOS was installed to get access to the /tmp/title.tmd downgrade bug, as a vulnerable version is available on NUS; the bug would be used to downgrade IOS15, which would then be used to patch other IOSes.[1] Nintendo fixed this in 4.3rev03 by releasing the Korean IOSes in all regions.
