Voyager dead (even to pings) after upgrade attempt

Hi Support,

I have an exact same problem as another member in the forum that asked for help. But since the resolution was resolved off this site. I will need to re-ask for help:

I tried to upgrade my Voyager but now it's dead and doesn't even respond to pings. I'm happy to try and reflash the sdcard but it prompts me for my original purchase details since I think I might need a new subscription.

Is there a location where I can just re-download the original version I purchased, or the last version that I was entitled to after my original purchase? Alternately, is there a "my voyager is dead and not responding to pings" debugging cheat sheet? I did try searching but nothing obvious jumped out at me.

I get and appreciate the logic behind charging for updates to the software but I'm hesitant to pay for an updated subscription and download if my hardware is essentially dead.

Thanks!
