It’s not recommended. Going back from Vangelis to Oram is not a tested path. Anyway you could try and see what happen.

Please, read this:

We warned about it.

> **PLEASE TAKE NOTE**
> 
> Within the next few days we will be merging our bleeding-edge development into vangelis (testing) branch. This will make vangelis a development branch that **should not** be used for production. (Not that you should have been anyway!)
> 
> Please move to oram to continue to experience a (relatively) stable workflow. Vangelis may be broken at any point (hopefully for not too long!) and should only be used to test the latest bleeding-edge developments. We strongly recommend using a dedicated device (or boot media) for vangelis, separate to your normal, day-to-day zynthian usage (which should use oram).
> 
> There are many changes in this development version and full forward / backward compatibility is not guaranteed. Indeed, you are unlikely to be able to move between oram and vangelis without a degree of hurt.
> 
> **Please heed this warning!** Move from vangelis to oram and / or do not update vangelis unless you want to feel the same hurt that we developers experience.

Regards
