Revert to UI5 when it was never installed?

I just set up a Vera Lite for my mother, and I absolutely despised the experience of using UI7 for the first time. Doing anything in this UI takes longer than it did before, all so non-techies can feel more comfortable and they don’t give the people who know what they’re doing any shortcuts. The UI also has the worst use of space I’ve ever seen. Why is everything so freaking HUGE?

As far as I know, this Vera Lite has never had UI5 installed on it. Is there any way to put it on there?

My apologies if this has been posted a bunch already.

Not having UI5 on Vera previously is irrelevant when downgrading.
