I've been attempting to do a hard reset on a Nextbook tablet> ID S7JNX16A10132S. All the info I have is that pressing the UP volume and power will take you into factory settings. On this one, it instead takes me to a boot option menu with Android-IA and Android selections; no sign of any options for resetting. Using a pin in the Reset hole on the back has no discernible effect. Any suggestions? Or is it an oversized coaster?
