Error when installing avast anti-theft.

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

Hi,

is your device rooted? Was the AT installation you got rid of rooted? Are you trying to install AT rooted?

Yes, my device is rooted. The AT installation that I got rid of is rooted. Yes, I’m trying to install AT rooted.

Appreciate your help.

Wait, I rebooted my phone and the installation worked! ;D
Problem solved.

OK, great :slight_smile:
