It would help if you gave us a model number or something to go off of.

Otherwise, the only way to officially upgrade is to do what you did, system updates-update software. If there isnt one available, which I doubt as most off brand devices dont support upgrades, the only other way to do it is to root and install a rom with the version you want. You would have to visit xda-developers and find a forum for that device, if there is even one available.
