In practice you have to do this;
Update the firmware (a microSD is fine too)
Update the map and keep the SD inserted in slot 1,
Copy the script to the SD card, when the new map is no longer displayed, it is inserted in slot 2 and "press any key to execute the script" will appear, and then you will see "script applied.press any key" and eject the sd card ", press the rotella and remove the SD card
Restart the MMI and the maps are active.

Yeah, it did that. I managed to clear fault codes by following page 40 trick from how to pdf. I reckon my map files are corrupted. Need to download again and checksum it.

Will try with another SD card.
