System Image of Andriod Device before OS upgrade?

Hello everyone,

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 :-)

Is your phone rooted? If yes, this is easy, if not I don't know of a way to do this perfectly.  Have you put the question on androidcentral?  Also note that the upgrade to Lollipop can indeed be a problem (since you are switching from the Dalvik runtime to the Android Runtime (ART)).  I have run into a problem on my Galaxy S5 where google plus crashes the contacts app after the upgrade (disabling G+ fixed everything).

you can you an app to backup and restore, you files from the app store, root the device will void your warranty, load cwm recovery in case you brick it. the install your os of choice.

no problem if you do it in that order

I don't recommend rooting devices,  but as far as I  know, there is no app that can do a full backup of the phone if it is not rooted including preferences. Super backup needs root access to do the best job.  Avast's backup can do most,  but not all.

This is what I figured.  I will wait for a month or so after the update is deployed and other people start to use it.  This way, I can see what their feedback is on the forums.

If general rubbish and or memleaktastic I will stick to the current OS, which runs butter smooth currently.

Thanks again for the feedback. :-)

Beware this upgrade.  I have done it and although there are features I like, having first contacts crash continually because of google+, and now having google services crash for some other reason is just annoying.
