T616 Firmware Upgrade

I found out why I was having poor quality with the Bluetooth Bluetrek G2 headset. Turns out my Sony Ericsson T616 has a very old firmware version. Upgrading to a newer version fixes the bluetooth headset issues.

There are three ways of going about this. The official way is to bring your phone in to, or ship your phone to, a Sony Ericsson service center. I need to find out if there is one near by. I don't want to have to ship my phone anywhere.

Another choice is to upgrade the firmware yourself using a cable and Windows software. The cable is called a "terminator dongle" and can be found on eBay as well as some other web sites. If there is no nearby service center, this is likely to route I will take. Some people sell this process as a service once they have the dongle and software themself. I'd rather get the dongle and software instead of sending it to someone who does, since then I can upgrade the firmware or perform other things to my phone in the future as needed.

The third choice is to have the phone remotely updated. I'm not exactly sure how this works, but it appears that someone else can update the firmware on your phone if you make a call to them. They then playback some instructions which are supposed to update the firmware. Apparently this is how Sony Ericsson supports their P900 out of the box.

Someone asked via email today how to check the firmware on your phone. So I thought I'd add a comment here in case future people come across this entry.

To check the firmware, enter this sequence using the joystick and the star key: > * < < * < *. This will enter the service menu, where you can view your software configuration and other things. The firmware version is listed under "SW Information". My current firmware is R1B027.
