I have an RCA Voyager tablet (Android 6.0.1) plugged into my computer with USB debugging and everything. I launched Droid Explorer and am following this guide for rooting (http://forum.xda-developers.com/showthread.php?t=2684210 - method 1). For whatever reason, having it in recovery mode doesn't show up under Ubuntu, and all I got from Ubuntu once was a "Failed to mount Android." Anyway a comment suggested this app, but it isn't showing any files. I just freshly installed this and all of Android Studio last night, what am I doing wrong?
I had the same issue. After opening the console it showed me a message telling me I had to install busybox. After installing busybox from here the file browser worked.
