Upgrading Jelly Bean to Kit Kat on Droid Razr Maxx XT912

I decided to upgrade my XT912 to Kit Kat. My earlier rooting and upgrade to CM10.2 provided a much better experience on the aging hardware (http://blog.trebacz.com/2014/05/eliminate-lockups-and-freezes-Motorola-XT912.html). This was my first time upgrading major versions of Cyanaogenmod (10.2 to 11) on my phone, so I was prepared for some unplanned issues. The upgrade went flawlessly and I lost noting in the process.

The procedure I followed was:

1. Download current cyanogenmod snapshot from here:

2. Download Gapps for CM11

I used the upgrade steps from Jack Stromberg's post here:

I found I needed to modify the steps slightly for doing and upgrade from 10.2 using safestrap. It was all in the instructions, but you do have to read between the lines a little bit. Here are the actual instructions I used for my successful upgrade from 10.2 to 11.

3. Do step 15 and 16 (copy files over to your XT912 using windows). Then go to step 23.
4. Do step 23-26. On step 23 I just disconnected the phone a rebooted.
5. Do step 28-35 to overwrite CM10.2 with CM11. During reboot had to wait while CM11 updated all apps. Then CM11 started.
6. Do step 36-44 to install the updated gapps for CM11.

After the final reboot I was pleased that all my apps were installed just as before. I didn't have to reenter any Google or app credentials or wifi passwords. Everything just worked. I was very pleased with the ease of upgrade from one version of Cyanogenmod to another.
