my cousin forget his password for samsung tab 4 and wants me to fix it for him. First thing came to my mind was hard reset however, the tablet needs home+ volume up+ power buttons to be hold down for reset while my cousins home button is stuck and can not be pressed. I tried hours to unstuck the home button but a black thing came out which I am assuming a melted plastic, but the button did not come out or did not get fixed. I don't have tools to open the case. Do you have any suggestions ?
