previously unheard off here so I doubt anyone has much information for you I'm afraid. you will need to find out which cpu it has in order to direct you further, if its an InfoTm x220 then try HERE
, and if it is an A8 Cortex then try HERE
. Neither of these groups are specifically for your model but they are the same class of device.
Thanks for helping out! On the back of the tablet there's a sticker, "infoTMIC," so I'll check out your link and see what I can make of it.
Appreciate the assist,
