Hello, i have the samsung galaxy 10.1 gt-p7510 tab. Earlier today i turned off the tab like i normally would, but when i tried turning it on again a while later, instead of starting up normally and going to the desktop, it got stuck on the samsung galaxy tab logo. I then tried to turn it off and on again, but it didn't turn off completely,instead it turns off for like 2 sec and then displays the logo again and stays like that. I did try to connect the battery and turn it off, and it does show the battery, but won't start up normally. I have no idea what to do and i wouldn't want to return it. can someone PLEASE HELP me?? I would really appreciate it.
