Read up, this for one:
Additionally users have reported bugs from Play Store errors, log in / accounts issues, and probably other things from doing that.... Most importantly, you are getting no gain from doing it. The update will be pushed to your device at the same time anyway, you cannot speed it along in this method. Your device does automatic checks with the server to see if an update is available at set intervals, and you can have it check more by clicking the Check Now button as much as you like. The framework settings data clear "hack" accomplishes the same thing as clicking Check Now for updates, but in fact does more things which can cause you some headaches later.
tl;dr - Click the Check Now button to see if you've been given the update, or wait for your device to look for it automatically. Don't clear the framework services.
