This will root the Wopad V7+ with Android 2.3.x installed on it:
1. The first step is to install the Android SDK on your computer (not the tablet!). It can be downloaded here, for Windows or Linux. As part of the installation process, you can install the platform tools, which you will need.
2. Connect the tablet to a USB port on the computer, using the
USB OTG port on the tablet. Go into 'USB debugging mode' in the
tablet, and also select 'USB connected.' Both of these are
available from the top pull down bar on the tablet when the tablet is
connected to the computer.
3. On the computer go to the directory where adb (adb.exe for
Windows) is located. This should be the platform-tools directory
under sdk.
4. Run commands:
adb root
adb shell
cd /bin
ls -l (to show what's in the directory)
rm ./su
5. You can now disconnect from the computer.
6. Install the Gingerbreak apk available here and run it to root the device. It will install the superuser app.
