SOURCE: Sony Ericsson - phone lock code

Hi Cheryl!!!

I think i may have a solution for u. It sounds like a Phonelock code...all Cellphones have one. Its in the software for the phones. Its a little like a SIM code. U could try with entering the code 0000. That could work!!

Good Luck :-)

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!

You can get the unlock code through online..........give your IMEI number and get the unlock code for ur mobile.... i will suggest the website Unlock-Zone.com which is doing good service .....you can approach this website.
This site is nearly perfect and they were recommended highly in the cell phone forums. I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.
