Hi, I have the Droid Turbo and I am getting ready to install Lollipop, I have always performed a factory reset before a os install and I am ready to do this now, the problem is I don't want to lose my collection of Moto 360 watch faces. I have ES file explorer and I can see the files in the Facer folder, can I just copy the file folders to a thumb drive and then move them back after the update? I don't want to start over from scratch again. What's the best way to save my collection?
