I have tried side-loading, converting the app, nothing succeed. When I have converted .APK to .bar format, side-loaded on my phone I got the -12 failure. I am loosing a hope, because I just got the smart bracelet and it works only with the ZERONER app. I have BB10 with the latest update of OS. Can anyone help me?
http://www.appsapk.com/zoner-antivirus-free/ to download the apk. Store on your phone. Open in file manager and the app should load unless there is a Google Play issue. If different issues come back for more advice.
I installed google play app on my BB10
following the step how to install Google play app store on BB10
then via the Google play app on your BB10,
search for Zeroner and install the app.
Mine works great.
