Hi scream422, congratulations on your new tablet and welcome to the forum. Nice to have you as a member of Android Tablets. I'm moving your thread to the Coby Generation 3 forum for you, where more people familiar with that tablet are likely to join the discussion and try to help you. Good luck!
Coby never made system images available, so the best you can do is the collection of system dumps in Generation 3 Development. Instructions on how to use them can also be found there.
