Firmware and Barcode error


Hi the first post, of many to come I think…

1: When trying to install the app (both iOS and android) I get the message to scan the qcode. What qcode?
2: when trying to update the firmware the sad card isn’t recognised or the firmware isn’t. When I put the same card with gcode on it then it works fine. When doin the update I make sure that The card is clean, nothing else on it only the firmware / tft

Any clues on either would be nice.
Thanks in advance
