I want to access all my files on my android phone (ZTE N817 Legacy) and have downloaded adb.exe and fastload.exe. Using adb, I can issue a shell command, but when I try to access most of the directories, it gives me a message "Permission denied." I'm fearful of using fastboot as I'm not familiar with it and know the consequences can sometimes be disastrous. I merely want to copy the data from my phone. I used syncdroid for most of it, but it doesn't back up apps, for instance. Also I want to find out where everything's stored. Explorer shows practically nothing, and I've combed through every directory several times, and it is set not to hide any files.
