Can't turn on Turris MOX

My earlier solution only got the router working temporarily, then it was this issue that I started hitting (router breaks itself at least once a day) Reboot doesn't work - #27 by peci1 - SW help - Turris forum

I have tried from the beginning, but they only respond once in a while. At one point (Feb 29) they said:

For orders purchased on Indiegogo,
we provide a warranty in 2 years length according to the EU law. During that
period we can repair it or provide you a replacement.

but they have been very unresponsive.

Emails I have sent (dates which my emails actually got response in bold, you can see only 3 out of 13 emails responded to):

  1. Sep 9, 2019: debugging included. No response.
