We need to use EMMA tool to flash Xperia X with a sony android image that is more open than the one installed. After which you use the flash script to flash SFOS onto it?
There are two flash-modes on the Xperia X:

The (pretty much universal) fastboot mode and a more "powerful" sony-specific flash-mode.

There is a special partition on which Jolla is supposed to put the xperia-x blobs on (closed source drivers, which are unfortunately necessary on all current smartphones).

This special partition is by default not writable in fastboot mode.
So Sony is providing an update that enables this special partition to be written using fastboot.
This update can only officially be installed using emma, the flash-tool by Sony (which works with the sony-specific flash-mode).
After that the blobs can be written to the special partition in fastboot-mode.

That is the official ways of doing things; there are ways around the requirement of emma by writing the speical partition while the phone is booted up or in recovery-mode but these are unofficial for now.
