Enable USB debugging from your phone’s settings – Settings > About Phone, then scroll down to the build number and tap that number for around 7-times ’til the Developer option appears. Hit back to Home > Settings > Developer option > Enable USB debugging.
- TURN OFF the Reactivation Lock – This is only needed if you already turned-it-ON, from which you cannot modify the system when it’s turned-ON. Go to Settings>>Security>>Reactivation Lock and then uncheck the Turn Reactivation lock on.
