Have I bricked it, trying to upgrade?

Hello everyone.

I made a post some minutes ago about how my firmware wouldn't let me install, as the 3.80 HX Edit prompt kept showing to install it.
After I tried to install it on another drive and see if it works, I eventually cancelled it.
Now my HX Edit screen is black and I can't even create backup points, I press it but nothing happens.

I 'm so sad, do I need to uninstall and go fresh or?
