Wow, fantastic. Thank you so much dagos.
In the end, used this link, written in Czech, and followed his instructions.

It worked perfectly, and now SiMoCo works as well.
His instructions are identical to yours, but yours is much better, as you explain everything. Thank you. You are brilliant.
My only concern is that your C55 is lg1, and the Czech one was Czech (obviously).
Should I re-flash using your lg1?
