Rebooting Problems in Smartphone my phone got dead and know even after charging it up properly its not starting and Samsung logo is appearing again and again even pressing "volume up+home button+power button "isn't helping ..
Please help I have very important data in may phone and don't want to loss it all.  my Phone Model is GT-S5282.
You said that you have some important data on phone. Using "volume up+home button+power button" combination in some phones hard resets the phone. So taking your phone to a service center is a good solution.
