I have a mid 1006s super pad china android 2.2 10" with ddr 512mb. 4gb flash memory. 1.0 ghz imapx220 processor. I was trying to get the usb to work on my computer . I found some program call z4root and installed it then I checked to see if it was running right and it was but my usb still was not working. so then I unrooted it I think and then my tablet will not boot up the home page. If I push down the menu button 4 or more times the home screen shows up for a second with the wheel trying to load up but then goes back to black. I have pushed the reset button and nothing and tried to upload some new programs with a sd card but Im sure Im doing something wrong there or just the wrong program. Please Help I just got this thing and I do like it.Thanks so much.
