Oh dear, last month all my colleagues did an upgrade on their MDA aka Hermes 9600 for a newer ROM version. Unfortunately, I was not able to find any upgrade for the Xda Trion at the O2 XDA website. Also the German O2 website does not provide any information about ROM upgrades. Here I finally fond some information about O2 taking their Windows Mobile upgrade quite serious and the most importing information: All the upgrades are hosted by HTC directly. They even adapted the O2 style on the Windows Mobile 6 Update for Xda page.

All you have to do is to enter the serial number of your Windows Mobile device (right behind the battery) and download the corresponding 52 MB bits. Before installing make sure your ActiveSync connection is set up properly and running. And that’s currently the only drawback of the whole story: I tried to perform the ROM upgrade first with my Windows Vista machine. The upgrade process seems to run up to the point where the application tries to upload the ROM files. At this point the application does not work properly with either Windows Vista or the Mobile Device Center. Therefore, I did take my Windows XP backup machine. There you simply plug-in your device and make sure that the ActiveSync connection is established.

It looks like the SPL version (whatever this is) was not updated by my first attempt. Connecting via ActiveSync showed a different version (2.03 instead of 1.04). After confirming the setup procedure on your desktop machine, the screen changes then to a progress bar. After approximately 10 minutes the ROM upgrade is complete, the device restarts and shows up the new Windows Mobile 6 screen.
