Before you continue with the reprogramming of the firmware, please make sure that the device is installed on your computer. Remove the chip from the cartridge or seal it up. And make sure that any other devices (except mouse and keyboard), which are connected to your computer via USB or LPT ports are disconnected. It’s preferable that the computer is connected to the "UPS" (uninterruptible power source) device, because if during the reprogramming process the electricity source has any interruptions, then the reprogramming will be carried out with an error, which makes the device unable to work.
Be aware that with the reprogramming of the firmware the manufacturer’s warranty goes lost!!
