What are the prerequisites to be able to update the firmware-version of your mobile phone by using the SEUS (Sony Ericsson Update Service (via the Windows-application)) and/or by using the FOTA (Firmware update Over The Air (via the mobile phone))?

It appears that it is not only the current firmware-version that is the prerequisite, but something else too. Does the CDA identifier has something to do with it? Some people say it has.

I am asking this because as far as I have understood it, some people have been able to update their mobile phones firmware-versions, while some people have not been able to do it, even if they have the same firmware-version. However, I might be wrong.

I must admit that I am both a bit confused and definitiely curious.

Any clearification is appreciated! Thanks in advance!

CDA customisation DOES get checked besides the FW version.. And if I can take the liberty to shoot in the dark, SEUS may be tracing IP (geog'al location) too and decide thus.. This message was posted from a S700

Ok. Thanks.

What does CDA stand for? I know that it has to do with localization of the mobile phone, but what does it stand for?

Not even Google is of much help in this case... .

It stands for Customization DAta or something. It's the country- or operator-specific customization of a phone (including bundled themes, settings, limitations and such).
