Why does my SuperUser not have root privileges?

    Or is it just that Android's root user isn't all it's cracked up to be?

    So my phone is an LG Optimus Fuel L34C KitKat.  It's towel rooted.  When I'm in Terminal Emulator, when I've SU-ed to root, there's whole lots of things I still can't do that in the rest of the *NIX world, root can do.  When I try to create a directory within '/mnt' as the mount point for a new partition, it refuses ("File system is write protected").  When I execute a command (as root) and try to redirect the output to a text file, the text file only shows up in Terminal Emulator, not in any of the Android file explorer apps, or in Windoze Explorer.  It's like it only exists within the confines of that shell.  I edited a config file using 'vi' but couldn't save it as edited because "File system is write-protected."  And I can't change the permissions on a directory, or even a file for that matter.  There is no error message, the command appears to exit normally but there's no change.

    I just downloaded an app from the Google store, and I wanted to copy the installation file to my external SD card for safekeeping.  But when I tried to copy the APK file in Terminal Emulator, 'cp /data/app/filename.apk /storage/external_SD/apks,' once again, the command appeared to execute normally and exited without complaint, but nothing happened.  No file was copied.

    Is this normal Android SuperUser behavior?  Is it a shortcoming of Terminal Emulator?  Is this any way to run an operating system?  Halp, Mistur Wizzurd!

    Its not the app its the device.    -something to do with the way its partitions are mounted, since it haves an internal sdcard/emu mounted-

    But you can copy the apk to your external sdcard by using root explorer.

    Go to the directory where the apk is at *data/app/* long press it til youll have options, choose COPY do not choose MOVE, then go to storage/external_SD/ directory tap on paste, it should work.

    ***Oh yeah is busybox installed???? If not install it and try it using the terminal emulator

    ***The dev for superSU should be already be aware of this new firmwares, i assume

    Have you tried SDFIX (playstore) ?
    In kitkat, apps are only allowed to read/write to their own folders. Sdfix will change those permissions to allow (global?) access. It's not your root, it's OS.

    Not I haven't but I'll give it a shot.  As if a postage-stamp sized screen isn't handicap enough, not being able to capture CLI output to a text file is just adding insult to injury.

    Thanks for the tip!
