Been using for almost 6 months. Screen stays black despite trying to unlock device. Downloaded and connected to escribe to update to latest firmware. Once finished applying, screen flashed with 2 clock errors but then went back to being black. Device monitor is full of errors. After opening device monitor, escribe can no longer recognize device unless i close program and reopen. I am running as administrator. I have used multiple usb cords on different usp ports on different computers. I have also tried using different batteries. I am at my wits end trying top figure out what to do.
