How can I root my General Mobile e-Tab 7b tablet? 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.
