my serial number of the device starts with SN: SA9XHQCH90215, please tell me which version it refers to 922X or B922? To change the firmware and not spoil the device
SA9X is our latest version of the machine, it comes with an SD card, you can use dual systems, the firmware can use C92X version, because there is no change in hardware.
