Hi I am new to this forum stuff and this tablet. I got it used and the guy set it back to new, I can't get the app market to come up. I get chinese stuff and really would like to americanize this tablet for my personal use, i can't get music on it and don't really know how to update or upgrade the ROM? if that is what I have to do...I really need someone to walk me thru it either over the phone or step by step can anyone please help me? thank you C
