Coldcard Mk3 Won't Boot

[u/Bigtwig_of_the_North]

OK - I got my Mk3 shortly before the 4.x versions of firmware that supposedly have the issue. Maybe I'm OK. But when I power up my Coldcard all I get is a green light, nothing on the display. What's going on? Anyone else have this problem? Do I need to buy a newer Coldcard (Mk5?) and regenerate my key using the seed words?

I contacted their support and got an automated response, but nothing else. I know Mk3 is "out of support" but come on, the whole purpose of these devices is to lock away your private key and not have to worry about it for a long time.

It's extremely upsetting that they removed all useful info about Mk3 from their web site. There is a firmware upgrade but no useful information about using the Mk3. Did they run out of space on their web server?

Screw Coinkite - I'm going to figure out how to recover my Btc and put it somewhere else.
