samsung galaxy tab 2 7.0 does not start
i bought a Samsung galaxy tab 2 7.0 on Ebay for cheap (as it has ' battery problems') when i received the device i realised the tab works fine except that its battery did not charge at all and had to stay in the main at all times to use. I was then planning to buy a new battery fit it in and then the tab would be fine. but just in case i decided to take the back off the tab and to disconnect and reconnect the battery just in case it wasnt put on right or something. when i opened the tab i unplugged the cable of the batterry and then put it back in place and returned the back. but now it would not even start with the mains at all. I tried holding it down for long, holding power and volume button for 2 mins... NOTHING! when i connect it to the computer via the cable it does not even connect the memory and sd to the computer (hope this helps)
does anyone know why this is happening and what the sollution is
thanks guys...
