After removing the damage charging port pin2 and pin4 lifted, in other words it was opened circuit. If this pin2 and pin4 is open, you will not be able to reprogram the tablet. The only solution to the problem is to find the data ways. Just simply jumper it. You can see a hint on the image below for the connection. After applying the 2 jumpers the tablet can now be reprogram. I use CM2 dongle to reprogram the tablet.
