Unhappy [Q] Kurio 7s

Hi all.

Apologies if I have posted this in the wrong area, I am quite new here.

I got my daughter a Kurio 7s tablet a few months ago, and I should have known better. Basically, it has became a nightmare to use due to the navigation and such. Basically, it's a mess and is running painfully slow.

Recently the Google Play Store became available for the device which was an added bonus, but it still isn't a great device. I was wondering if anyone knows of any custom roms (or even a standard android rom) which could be used to replace the awful Kurio stock rom which has been pre-loaded onto the device?

Also, it has been quite a while since I have rooted any devices (I rooted a Galaxy s2 a while ago) so my memory is a little foggy in that respect. I have learned by searching around that it is possible to root the Kurio.. I am just wondering really if there is more I can do after the root to make this a more pleasant tablet for my daughter.

Much thanks and again, I apologize if this is posted in the wrong area.
