Firmware update to old version

Hi all,

Recently I updated my Sony DPT-S1 and I just don't like it

My Sony looked like this:

And now it looks like this:

I don't like the toolbar on the left and I like it even less that I can't hide it and show it all the time.

My question is, is there any way to get back to the previous version of the firmware update?

I've tried the "Reset Device" option but has not returned to the previous version :(
