Latest number must be equal or higher, so there is a compatible otherapp.bin.I was stuck on firmware 11.0.0-4U as well. I had the same problem. I forgot to leave the WIFI switch ON when reverting to an older firmware. Now I'm screwed. I'm glad I found this thread. Someone mentioned purchasing Yoshi's Wooly World in order to get firmware 11.2.x.x But BE ADVISED:
It comes with a firmware that is ALSO incompatible with the soundhax otherapp exploit. It is firmware version 11.2.0-4U
I just blew $40 on this game that I don't even want.
Does anyone know which firmware comes with the "Story of Seasons: Trio of Towns" cartridge?
And for that matter, does anyone know which firmware will come with "Mario Sports Superstars"?
in summary: DO NOT BUY the YOSHI GAME TO FIX THIS PROBLEM.

Also, I got a copy of "Cubic Ninja" for $25. It seems that isn't going to work since my firmware is 11.2.0-4U now. I still can't download a matching otherapp.bin
