I'm still running the original firmware where OTA upgrades doesn't work so I figured I should finally upgrade it. I connect a USB-cable from my Win10 PC to the micro-USB port on the minix, start up the burning tool but there's no device there. I can browse the minix from my PC but it doesn't show up in the burning tool so the cable seems to work fine. If I select the firmware and click start, nothing happens other than the start-button changing to stop. I left it there for 45 mins before I stopped it. Any ideas how to upgrade it?
