Can I downgrade RGH dashboard to work with Dash Launch?

[vicicarus 19]

Thank you for any and all help provided,

 I got a 360 serviced(RGH) but it has 2.0.17489.0 dashboard which I think is not working properly with dash launch(3.15). If I extract my nand, can I downgrade it to a lower dash(2.0.17349.0) I am unable to open dash launch to set the aurora path and I rember running into a dashboard issue like this before.

Yes, just reflash the nand using the same method you would if you upgraded it

Thank you very much for the reply,

YES!!! It worked. I had always updated, but never had to fall back. My Dash launch works now! Last time this happend it was a matter of just updating dash launch. Thank you again swizzy for all the help and assistance.
