Hi Everyone, I have a Samsung Galaxy Tablet. This systems seems to function, turns on off, menu and return light come on and off, sounds work, no screen, no user interface the screen only “glows” dark gray. I don’t think I have it in debugging mode. I have tried button combinations and unplugging battery. I would love to get some pictures off. I can access it with adb. For example, adb devices returns serial number? unauthorized. I cannot figure out what unauthorized means. I really don’t know the adb command set. I try adb shell input text pw, adb shell input keyevent 66 and it returns error: device unauthorized. This adbd’s $ADB_VENDOR_KEYS is not set;…I tried deleting the key file in my user directory. Any advice on the $ADB_VENDOR_KEYS and after that any commands to copy files on an unknown file structure on the tablet to my PC. Kind Regards.
