IOS31 is used by the Regional Titles for News & Weather, and contains the slot-LED blinking code. The RiiConnect24-Patcher changes IOS31's RSA-Key, so it can download custom Weather- & News-Data.

Together with IOS30, and IOS37, IOS31 did not have its /dev/flash access and ES_Identify hack patched in 3.3rev03; instead, it was fixed in 3.4.

The only known differences from IOS30 seem to be that a value in NCD was changed from 30 to 31 (probably changed in all IOSes), and the FS module was replaced by an FFS module. Like IOS30, this IOS starts its content IDs from 2, indicating that there was a monolithic version in development before v1037.
