I have a Nabi 2 tablet for my granddaughter. I've tried to charge it, but it will not charge. (I have 1% left) Ive tried to charge it with different chargers and USB ports, but nothing has worked. He chargers and plugs are fine. The charging light does not come on at all. I tried to do a factory reset...and I tried to erase all data. When it gets to reboot, it cuts off. Now, it will not turn on at all. What is wrong?? What do I do now?? I just dont understand. ....someone, please help me.....
