I have a Samsung Galaxy S3 GT-19300 and it is in a bootloop. I've tried everything from factory resetting it, restoring it from recovery mode, turning it off and on, taking the battery out and even 'hitting' on the power button. But nothing happens. It's still in the bootloop. I plugged it into my computer and not all of the devices install successfully so I can't connect to Kies or anything to get into Emergency Recovery Mode. What should I do? Am I doing something wrong?
