Sony Mobile Emma is a cell phone flashing tool which was developed by Sony themselves. It can be used to flash firmware versions to a few different Sony Xperia models and doesn't work with many older handsets.
Android users of some of Sony Xperia models can use Emma to customize their system software, most notably by installing custom ROMs or those officially released by Sony Mobile.
There are a couple of drawbacks to using Sony Mobile Emma, though. Namely, you must own an unlocked phone in order for it to work, otherwise you're stuck with the carrier's own software. If you have an unlocked phone, just plug it in with a USB cable and the software should recognize it once system drivers have been installed properly.
Flashing is easy, due to the app's simple user interface. Installing standard Sony software is easy: just select the version you want and the rest should be taken care by the Sony Mobile Emma application.
In conclusion, Sony Mobile Emma is a useful application for owners of certain Sony Android phones and can quickly revert any customizations made by custom ROMs downloaded from places like XDA-Developers.
