For some reason, downloaded miis that I "took ownership" for cannot be sent to another system, via wireless or qr code.
EDIT: I got the error because I forgot the mii already existed on the receiving console.
I found a workaround for errors with loading the vwii system menu on rednand:
Make sure the wiiflow channel is installed on vwii.
install the wiiflow wii u forwarder from:
open the forwarder and wait for wiiflow to load. then exit wiiflow and the vwii system menu will load!
