Ok, THIS WILL WORK! It worked on my W580i and it wasn't even supposed to. FIRST! Download (8.8MB) XS++ From HERE:http://forums.se-nse.net/index.php?showtopic=16338
SECOND! No install. It just runs.
Make sure you have ALL drivers for YOUR phone. That should be under the bettery. Under model... or something like that. HERE! http://www.nodevice.com/driver/company/Sony_Ericsson.html

Take your phone, turn it off. Start this program and click on connect. You'll have 30 seconds to plug your phone into your computer and HOLD C The entire time! (the delete button or 2). If connected, then click at the button: GDFS. There will be a phone lock reset to "0000". Click it. It will take no more than 45 seconds. I promise. Unplug your phone, and vuala! If your phone won't turn on, try pulling out the battery, putting it back and trying again. This program is also good for flashing phones, and putting flash menues on your phone. Also unlocking it and debranding it. GOOD LUCK!
