Not important really, more for my personal purposes. I see that Lollipop is going to be available for my device soon (1rst gen Moto X). I have done OS updates on different Android devices before and they can almost ruin the phone, making what used to be a fluid experience, grind down, often enough (not always) in exchange for gimmicky features or a new UI.
What I would like to be able to do, is effectively take system image of my phone (backed up to my computer of whatever), of the exact state my phone was in before I started the OS upgrade process. Then if it turns out that the Moto X implementation of Lollipop is non ideal for whatever reason, quickly revert back to the backed up image stored on my computer?
Is this possible? Has anyone done something like this, does Motorola offer tools for this, or does it require rooting and other third-party tools? The latter I respect and have done in the past, but just cant be bothered with these days, lol.
Thanks to anyone with advice or suggestions :-)
