I know it's been over a year but did you ever get it figured? I just got a used dragonmint and can't reset it I've tried everything.

So I bought 2 used dragonmint t1s, I just finished wiring in my 220 outlet in my storage room, and they both booted up just fine. Both started working right away, I figured that it just had never been reset. So I pushed both reset buttons for 30 seconds, it worked, the power light stopped blinking and is now solid, ethernet port lights are going. However when I go to the ip I am unable to sign in, it loads and loads but never finishes. Does anyone know what I can do to make it work? Upgrade firmware maybe? The only thing with that is I have no idea how without getting into the dashboard. They have a slot that says "tf" but looking inside them they don't really look like SD card slots.

If anyone could please help it would be appreciated
