Well I've got a tablet 2-3 weeks ago, also my first android OS so maybe I've not enough experience with android but better you contact the manufacturer of you tablet at first and ask him about an update or any other compatible OS.

Also search for your tablet name in combination with other OS. Can't help you further, cause yesterday I did my first android upgrade ever (Gingerbread to ICS) and I'm a bit disappointed about the game support (it's like there isn't anything about this, 20% only works till now hope they'll fix them)

By the way I've got the ICS update from my manufacturer (51Cube) so better to ask your manufacturer before you install something weird specialized firmware.

oohh.. i find its model name.. it is NetPad A91.. but i still cant find it firmware on internet.. help
