Hi Scottie, i I also just bought a used Q.
It came with firmware V3.0 installed but wouldn’t connect to Leica Fotos. So I tried downloading V3.1 from Leica.com but it repeatedly failed to load, iI kept getting a ‘Download failed-Network error’ code. So I emailed Leica technical service in the US (I’m in Canada’, they were brilliant and WeTransfered me the firmware update, the technician said they’d been having trouble with that download link lately. Perhaps message them or I’d be happy to send it to you. Hope that helps.
