You don't need to remove One Loft Race firmware in order to install the new one. The updating process will automatically erase the old firmware and install the new one. To update the firmware of your BENZING M1, download and install the new BENZING M1. Download the program from the official page. Make sure you choose the correct version because there is a version for 32Bit and 64Bit operating systems. Once you launch it, the program connects to the official servers and downloads the latest firmwares. Then you can connect your BENZING M1 with a power supply or a USB cable to your PC. When you press Next, you have the possibility to select the firmware version you want to install. I recommend that you contact the support team for further information.
