I had not used my Samsung Tablet 2.0 in a very long time. So i forgot the pass code, my old gmail account information, and the pin code. So i saw online that i should just reboot it. Well i followed the steps by turning it off and then holding down the power button, and the volume up button. But it never came on like it said it should then go to the android. My charging symbol also has a red X over it. Please help!!
