Two weeks ago I tried to root my android phone using Kingo root app on android but somehow it went wrong and it stopped but it copied the Superuser.apk to system/app and now I want to delete that file using adb. But when I type rm superuser.apk It gives the following error : rm failed for superuser.apk, Read-only file system and when I use to mount the file system with read write access with this command : mount -o remount,rw /system I get this error :mount : Readonly file system. I dont know how to delete Superuser.apk, Please help me, thanks

  • Are you superuser? You know you can only use mount when you have root permission?

  • You need to properly root and remove that file or flash a stock ROM to reset the /system partition.

    If you want to properly root your phone, check xda-developers. Search for your exact phone model and follow the simple step-by-step guides to root your phone (might require you to unlock the bootloader, but I don't have a Huawei to confirm).

I think your phone has been rooted and the just thing you need to do to remove that Superuser.apk is

  1. Open adb shell.
  2. Type su(It will give you superuser access).
  3. Then change the file permission (mount the system folder to read and write) and just simply remove that app.
  • No bro you just missed it, it isn't root, the rooting process failed at the middle without and recovering and I'm finally giving up root - :(

  • @Halo_HeroOfReach As far as I know, the app like Superuser or Busybox are copied to the phone only after the phone has been rooted. Have you tried typing su in adb shell?
