Rooting an unbranded tablet
If you don't know what device you have, it's hard to get any assistance.
Without any warranties of success, and without assuming any responsability by what may happen to your device, I can suggest that you visit UnlockRoot, known to work with tons of devices, may became a solution for yours.
The process is done with three steps:


Your device must be in USB Debugging mode. Turn it on, go to Settings-&gt; Applications-&gt; Development and check the box.（Look Here）
Connect your device to your PC, Run UnlockRoot.exe.
Click &quot;Unlock Root&quot;, enjoy!


And it's reported to work quiet well, see last entry labeled &quot;What are the Risks of Rooting?&quot;.
The FAQ section is also quiet useful.

Read the documentation from the website and proceed at your own risk.
