Of course, as with any update there are some requirements involved. For Atrix Owners who have loaded unofficial software on their phone, you need to be on system version 4.1.26, 4.1.51 or 4.1.52 to install the latest official software. Unfortunately, if you are not on one of these versions the update will more than likely not work.
From what we have gathered the update will take approximately 35 minutes, you will need 2.8 MB of space on your computer to store the update, and you will need to have your phone of course.
This is a big step that Motorola has taken to help get certain users back onto official software. If you are an Atrix owner who meets the minimum requirements than you can head over to the Motorola site here and get back on official software.
Let us know how it goes!
