I have several of theses 1th/s miners, one had its card wiped by 'accident'. I have been trying to install firmware onto new sd card, have flashed the card so many times it is reporting me to police! This 'easy' process has been sworn at, cursed and almost thrown in bin. Can I purchase the firmware already flashed to a sd card, or can I clone one of the other three (tried simple way- no play today).

   Please help, really, really doing head in now.

    Thank you in advance
