What is CDA version ?

Again, I don't think this update is possible for Orange users. If the update installer tells you that you already have the most current version then you are getting a false argument.

To expand on this point I believe the update can verify whether you have the most updated firmware provided by your contract carrier. Thus if you contract carrier hasn't approved the latest SE firmware then it technically can still state that its personal latest firmware revision is the most up-to-date. Carriers don't usually carry the latest firmware as the process doesn't permit them to on a technica/economical level. Moreover, different regions of the world will always have differring firmware revisions simply because firmware rollout dates vary for each vendor. That is plain fact. Thus becareful when a carrier states they have the "latest firmware revision". They are more likely going by their personal approved inventory and not neccessarily the manufacturer's rollout inventory. Unless you have a sim free unit you will have to go by your carriers timetable or resort to consulting an approved manufacturer warranty '3rd party' service point.

BTW: It is possible to trick the updater into proceeding with the upgrade. However, once one goes through the process the updater will return an argument that will notify you have a successful update.. However, if it is not working on an approved unit it basically "lies" because it assumed that you provided it with the correct credentials. To re-iterate I don't think the correct "credentials" include Orange or any other contract carrier modified phones..

Here is what your system info should display after an update:
