Im currently trying to refurbish a Eclipse 180g2-w rd 4gb red, its has video,audio,camera, sd card insert. my problem is i have no power going to into power supply it charges through usb, i thought it could be software but i think its hardware not sure, it turns on but there is no way to access it through usb to computer, i was wondering is there any backdoor for these type of electronics, so i can run a reboot with a new firmware. just cant get it to connect with the computer. if anyone has some knowledge im willing to listen
