You can flash the splash screen on a hisilicon box from putty/telnet.
I've changed mine on 3 boxes. An AX61 and 2 x SF8008's.
Just copy logo.img to /tmp
Connect to the box with putty/telnet and cd /tmp
Then issue the following command:
dd if=/tmp/logo.img of=/dev/block/by-name/logo
Reboot and new logo should be there.
Thanks to dpeddi & Ev0-BH from the Blackhole Team for the info
These are 2 standard logos and 1 I made myself.
