You have to take the phone to a mobile service center and have them reset the code for you.

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!

Phone lock code


by default the phone's lock code is 0000 (four zeros) unless you have changed the default lock code before, there will be no problem with the lock code.

Go to the service center of your mobile phone company and ask them to reload its software in it... otherwise try to remember that code!

Good luck

1. Connect your W550i phone to your PC using the USB cable.
2. Use it in File transfer mode.
3. Go to it's Others folder on the Memory Stick that just appeared over at the My computer screen. (probably called PHONE_CARD or something similar).
4. Copy the .jar files from your PC to the Others folder on the phone's stick.

5. Disconnect your phone properly (safely remove hardware) and allow it to restart or return to Phone Mode.

6. They should appear in your games folder. Otherwise go to your files on your phone (File Manager) and go to Others. and open the files.

Please let me know if this had helped you out. Please rate.

Phone lock


You should have a PUK number, on the plastic card where your sim card was. Enter 2-3 more pin numbers and your phone will lock itself and request the PUK number... tap it in and hey! presto.
PUK number is available from your service provider.

Other sim is not being accepted by w550i


The lock code is from your previous provider. They have apparently locked your phone into there company. You can ask them for the code but you will probably have to pay a small fee to release your phone. Or you can go online and find the code if you know how to look for it. Ebay sells codes to release your phone as well if that is any help to ya. Hope this helps and good luck.
