Welcome to Android Central! You'd have to see if you can root your device first, which means gaining total access to the system. Not every device can be rooted, and it may be difficult for you to find out if you can do it with a fairly obscure device like yours. Otherwise, you're stuck with whatever version of Android you have, and hope that Storex releases a 4.2 update over the air (which you'd be able to install by checking for System Updates in your Settings menu). This is one of the main disadvantages of having a device that isn't made by a major manufacturer.
