Focus FS-H200 Pro. How to do an original Factory Reset?

[Jorge Grundman]

Hello:

Does someone know how to do a Factory Reset to recover initial firmware of the FS-H200 Pro?

I have upgraded my Focus FS-H200 Pro and now the scroll wheel do not work and it is missing the F3 Label. I found the firmware though web.archive.org to work with the Canon XH-A1.

Acoording to web.archive.org it seems that a Factory Reset could solve it but there is no documentaion available online.

Thanks in advance
