Why Samsung Tablet wifi 10.1 won't upload?

[AC Question]

My Samsung Tablet Wifi 10.1 won't upload normally. it only comes to a battery loading icon when i try to turn it on. I charge the tablet over night (8hrs+) and it still has the same screen, the loading battery icon. I use the same manufacturing charger. so i know it works. I have try the Power+volume down button to hard reset it. doesn't work! I also try to erase all data and manufacture reset. Doesn't work. I also try to upload new firmware on it. Doesn't Work, uploading the firmware via USB, SD card. Nothing. I get the firmware on the samsung website and other sites. I don't want to pay a lot of money to fix when i can just buy a new one. Please help.

Is this a Tab 2? With the tablet unplugged, try holding down the power button for 30-45 seconds, then plug it in while still holding the button, and continue to hold it for another 30-45 seconds. If this doesn't work, it might be a bad battery connector causing this.
