This is my player
科王K658固件程序ATJ2085（小彩虹） | MP3/MP4固件下载区 - 数码之家 - 专业数字产品爱好者社区 but I can't find the firmware anywhere and I don't have an account on mydigit.net. Can anyone help me?
Edit:
After several attempts I have managed to get a removable drive and mp4 working but still a black blinking screen. What I mean is that is I plug in my headseats and enter in the menu as I used to it starts playing recording (record folder apears on drive with sevaral files) but still can't get it to show the color menu
