Unable to update Sync 3 (tried many USBS)

Hi!

I have been trying to update my Sync 3 (2.0) to 3.4, tried fords files from their website and also tried syncupdater. Also with 4 different USB sticks and 1 external harddrive. no success, same problem

When I stick the USB in it says “system is updating” for 15 minutes. then after that i suddenly disappears and nothing more happends, the computer wont restart, no error, nothing, that bar just goes away and does nothing to the system version, it remains the same. I tried also Master reseting several times…

I got a Ford Mondeo Mk5 2017.

Here is my log for the latest USB I created with Syncupdater:

As per Discord, you need to set your previous version correctly, you presently have it set as 3.4.20237 when it should be (for example) 3.0.18000
