PCM software downgrade and crankshaft position learn proces

[spacejam]

I upgraded my the pcm software of my car (Mondeo mk4.5 with dw10c engine 136PS 2012) with the ucds but it introduced a problem (overrevving during shifting with a powershift gearbox), is there a possibility to downgrade the software to an older version?

I also want to run the crankshaft position learning process, it there a full description of the procedure for starting it? If I want to run I see a few things, is the rest done by it self, do I need to drive etc? Can it be harmful if the learning process is interrupted?

I found the original version (via etis):
BG91-14C204-FJD

In UCDS I can only download the latest? Or is is somehow manually possible?

In Update Wizard click on "IDS Calibration Level", a dropdown will open, pick an older version, click on modul name to get the next button active, click next, download files, run update

I check it yesterday, but I only see one version in the dropdown list, is it somehow possible to select an older version of the software?
