Please help me with a rootless rescue Vanda

[Lilac]

I got this Vanda from HD clearance rack. It was in a decorative ceramic packed pot with white jagged very rough rocks. It had two tiny little roots begining to emerge from where dropped leaves used to be.

When I took it out of rocks, its roots had solidified in a round configuration and were brown and hardened. But one root was slightly greenish towards the stem of the plant and it had two tiny little green nubs, I guess roots?
the leaves have wrinkle lines diwn them and look dehydrated.

How much of a chance of surviving and perhaps even flowering does it have?

I have faith that I can save it, but I ask you all for advice. What can I do to optimize its chances? Thank you in advance
