Hi, I uninstalled avast mobile security and anti-theft as I had forgot my password to access it and it got rid of the password protection. But, when I'm installing anti-theft again, it gives this error message:
Could not write to /system directory(mount: Invalid argumentcannot create /system/app/com.avast.android.antitheft.apk:read-only file systemUnable to chmod /system/app/com.avast.android.antitheft.apk: No such file or directory). Retry (it is recommended to retry at least one time)?
This is on a sony xperia s, firmware 6.0.A.3.73
