Have u tried to power it off and then when u power it on while pressing down the volume down button once the samsung the volume down and select rest to default of it may to factory reset
I go there, but it does not show my device as being listed. I know that those techs who sold me my phone and set it up almost a year ago did this. I have tried everything to this phone - solution wise and to no avail I am still locked out. I have multiple things saved on this phone, including pictures of my youngest daughter who passed away not long ago & to think I have only a choice of resetting this phone to it's default, hurts my heart more than I could ever explain. These memories are all I have of what once my family. My emails are email@example.com or firstname.lastname@example.org. I have been to sprint & went to a repair shop who advised me to go online to the samsung website. I have tried to transfer to my laptop & it does not find my device. I am stuck, please help me.
