How can I root the General Mobile e-Tab 7b tablet? It's currently running Android 4.1.1, kernel version 3.0.8.
If you want easy root access and Developer support, It would be a good idea to get a well known android device from the likes of Samsung/HTC/Sony, etc.
I don't think there is good support for niche and low volume tablets.
Sorry to be the bearer of bad news.
EDIT: You can do something like this:
Look up the ODM of your Tablet. It probably is some Chinese no-label company. See other tablets which are based on it and check if you could root them.
