Wanting to use my own design as a bootlogo.

Currently using Whooshbuild on my Zgemma 2s,
I've created my own design I would like to use as a bootlogo,
I start up xorion bootlogo maker,
Choose my design I want to use,
Convert it to .MVI,
Input the IP of my device and root as username and password,
Send to my device,
It says it was successful,
Reboot my device but original bootlogo is there not the one I designed,
I've FTP'd into my device and the .MVI files i created are in usr/share just can't get them to work on startup.

Any help please.
