I asked the company for a newer android version but they always say that if the tablet comes with (for example) android 4.2.2 they won't upgrade or update the version of it :/...

I also asked the productmanager of the company and he also said that they didn't planned to and won't do something like that...

The problem is I don't know any clones... and I have no Idea if someone created a rom for this... another problem of the stock android this thing comes with is that it terribly lags and nearly every app crashes after 2 or 5 mins.

It's a rk3188 tablet with 1 gb ram and an 1280x800 screen.

Btw I also got the full system image from the product manager:

Hope this helps! It also includes the original kernel and everything what is needed.

The best thing would be android kitkat 4.4.x or 5.0 Lollipop o.O

Btw I also tried out the Odys Iron roms but they don't seem to work on this tablet ( Iron and Neo quad 10 are nearly the same tablet except the ram and screen resolution)
