Updating sgminer and the STM firmware seems to be all that is needed. Both are obviously found in the new image file using something like 7zip to open the archive, then browse to
1.img/opt/bin/scripta/sgminer and
0.fat/GX10.bin. Copy both to your X10, the GX10 file should go in
/media/boot. Rebooting should auto-update the STM firmware.
Remember to do
chmod +x /opt/scripta/bin/sgminer
after you've replaced the old version.
Don't forget about the web interface changes (adding of the new names) for people who actually use it.
