try searching XDA Developers, if the tablet has any support, they will be one of the first to find out from. rooting a tablet can be easy, or hard. there is a different method to each model and make. there is just no 'universal' rooting method. it will take a certain type of program or set of steps for YOUR make and model tablet. basically, the tutorial for rooting an HTC Sense, will NOT work on your tablet. and keep in mind that it could be one of the harder to root models, involving command line ADB hacking. that was sadly the only way i had at the time to root my ZTE Merit phone. i can only hope your tablet is one of those easier to root models.
