Voosoo V7S teardown

I bought a Voosoo V7S tablet from AliExpress:
(7" Voosoo V7S IPS Capacitive Android 4.0 Tablet pc 1.5GHz Dual cameras 1G/ 8G HDD)
If the link is down, here are some quick specs:
  • Item Type: Tablet PC
  • Tablet Data Capacity: 8GB
  • Screen Size: 7"
  • Battery Life: 4-5 hours
  •  Processor Manufacture: AllWinner
  •  Touch Screen Type: Capacitive Screen
  •  Processor Main Frequency: 1.5ghz
  • Memory Capacity: 1GB
  • Feature: Wifi,Webcams,Multi Touch,HDMI,G Sensor,Camera
  • Operating System: Android 4.0
  • Display resolution: 1024x600
  • Weight: 389 g
  • Processor Model: A10
  • The tablet worked just fine and was definitely worth $86.
    After playing with it for a couple of hours I dropped it on a wooden floor from about 1m and the capacative multitouch glass overlay cracked (thus disabling touch input) and the usb-port connector broke off from the circuit board inside the tablet :P
    So I decided to take it apart and see if I could atleast reconnect the usb port so I could use is as a passive screen showing some app or photos or whatever.

     You can see the cracks in the screen above.

    Just pry the back of the tablet off with a small screwdriver.

     Disconnect the cameras and other cables from the circuit board.

    After some work with the soldering iron I got the usb connector back in place! One copper lead had came of the circuit board so I had to trace it visually and then connect a cable from the usb connector pin directly to the component it lead to, hence the taped up copper wire above.

     Everything back in place.

     The capacative touch glass was glued to the cover plastic of the tablet so I had to loose it.

    This is my new tablet, sans front cover, being controlled with a usb mouse and keyboard (gotta love the usb host function!)

    I have not been able to root the device yet.
