Have you upgraded a Motorola Droid 4 from Android 4.1 to 4.2?
If so, please share how you did this.

thanks in advance

Welcome to Android Central! I don't believe there was an official update to 4.2, but you could always root the phone and install a custom ROM. Here's a link for rooting: http://forums.androidcentral.com/mot...droid-4-a.html

Thanks BDiddy.
What is a custom ROM? Is it going to be compatible to apps that only use Android 4.2?

The link you sent about rooting the Droid 4 says:
Put your phone in USB debugging mode.

How do you do that?

I'm not really familiar with rooting, so I'm not the person to help you. If you're a novice to smartphones, I'd suggest you not consider it, because you can permanently mess things up if you're not careful. But if you want to proceed, just do some searching for "Droid 4 root" and "Droid 4 ROM 4.2."

Can anybody out there confirm that there was not actually an upgrade to Android 4.2 for the Droid 4 phone?

This Motorola page confirms that the Droid 4 stopped officially at 4.1.2: https://motorola-global-portal.custh...JsaW9pWlZYbCJ9
