Chosen Solution

The tablet has a mini USB port. It broke off and now I can’t charge the device. Any guidance for replacing the USB port or charging it with another port (HDMI)?

I‘m afraid that you will have to desolder the USB connector and solder a new one in its place. Charging over HDMI doesn‘t exist I‘m afraid. You’ll have to crack open the device, locate the USB port and then use or acquire some SMD soldering skills. I hope I could help. -λ
