Pre-Requisites 

A. It is always advisable to back up all your data especially the important files you saved in your internal memory. While the update process is definitely safer than you think, we cannot guarantee things will go the way we want them to be. There are apps from the Google Play Store you can use to automate and make the backup process easier.

B. Check if you have installed the latest version of Sony PC Companion in your computer to make sure you have all the necessary drivers for stable detection of your device.

C. Check if you have at least 60% battery power to make sure you will not run out of power during process. There have been reported cases that phones become inoperable due to power loss during update.

D. Enable USB Debugging in your Sony Ericsson Xperia Pro and check if all your USB ports are active or at least, make sure you are using the active one.
