Downgrade TCM

[spacejam]

The ford dealer updated my TCM software of my ford mondeo (2012) with powershift gearbox. Unfortunatally it got worse, does someone know how to revert it to the stock software?

What step do I have to do to revert it and is it safe to do? I don't now which files to use and I there are also no other versions in the dropdown menu.
