Chosen Solution
My tablet is stuck on the Samsung logo screens. It keeps looping through those two logo screens, but will not continue past it.
Turn off the tablet.Press and hold together Volume Up + Home + Power button.Release held keys when the Samsung Logo appears on the screen.Select “wipe data / factory reset” by using Volume buttons to navigate and Power button to confirm.Next choose “Yes – delete all user data"And “reboot system now”. hope this solves it
