Default A3-10 Acer Problems

Hi,

I purchased a A3-10 Iconia Acer tablet today and have already rooted it.

I presumed it would update to KitKat ( I thought Acer being a big company would have an update). I can't get CWM or TWRP to install on the tablet or find a ROM, it uses the mediaTek 8125.

I've only owned Chinese tabs before... Will it be possible to update or should I just bring it back to the store?
