Does your phone have SIM card in it? You can insert that into your laptop (card reader via USB), move it onto the card, then insert the card back into the phone. Browse for the file and click on it. I have never done the GHL Ap like this but I did another ap a few months back on my Motorola Droid Razr MAXX.

The install to my phone was a simple "Click on the link" and off it went.
