You're on firmware 202303 update to 202306 wich is most current as of today. Also for the firmware update use a fat 32 32k cluster ruffus formatter sd card preferred a 32 or less one with only the firmware 306.img on it and plug it to one of your pc'cs usb ports(not front or extension ones) if u see a rocket let it do its thing until it reboots and shows charging then you can use your big SD card as fat 32 with the onion os in it. I'm on a 512gb card so any decent brand card will be fine for the OS
