Hi, im trying to root my phone on 4.4.2 using towel root and pie, but neither work, when i try and run adb shell chmod 755 /data/local/atvc/root.sh, i get the error: unable to chmod /data/local/atcv/root.sh: Not a directory, and that is using the pie exploit. When i use towelroot, i hit make it rain after changing the o in the string of numbers to a 0, and nothing happens, please help
