This is nice solution to remove sim lock for sony ericsson
mobile phone without any cost.
This application can generate SIM-Lock remover vkp patches that you can use with SETool2 Lite, Far Manager with SEFP (Sony Ericsson Flash Plugin) and compatible tools. It is able to generate vkp patches for DB2000/DB2010/DB2012/DB2020 CID 36/49/50/51/52 MAIN firmwares (*.mbn, *.bin), but at the moment you can apply patches to DB2000/DB2010 CID36/49 and DB2020 CID52 platforms only. You can also apply patches to any DB2000/DB2010 CID36/49 and DB2020 CID52 cross flashed phone (e.g. DB2010 CID49 K310@W200).

Unlocking tutorial
How to connect the phone to flashing/patching tools:
Many users asked me how to connect the phone to SETool2 Lite, XS++, etc., so I decided to write it up. First of all fully charge your battery.
I. Install USB Flash driver:
If you never modded your phone, then probably you don't have the USB Flash driver, what is required to be able to communicate with phone. So install the driver:
USB Flash Driver Installation - Guide
II. Connect the phone to SETool2 Lite(or any other flashing tool):
Click on button what you need/guide says(Identify, Read GDFS, etc.)...
When SETool2 Lite says to press the C key and connect the cable you need to:
1. Turn off the phone(if it was turned on)
2. Remove the battery, wait a few seconds(2-3 seconds is enough) and put it back, but DO NOT turn the phone on
3. Press and hold the C key on phone and connect the DCU-60 cable(data cable, what comes with phone). FOR W880 owners only: if your phone is a W880 then you need to press the 2 key instead of C key.
4. When you see some progress on SETool2 Lite status window(on left side) release the C key.
What is your phone's platform and EROM CID?
If you don't know what is your phone's platform(DB2010, DB2020 etc.) and EROM CID, then read this:
General Information about Patch-Unlocking (start here if you want to unlock)
A. How to apply the generated patches to DB2010 CID49 phones:
IMPORTANT: First you need backup the GDFS. If something goes wrong you can unbrick your phone with this backup. Here is how to do:
Open SETool2 Lite v1.08 or v1.11.
1. Select your phone model.
2. Click on
Read GDFS button.
3. Follow the instructions given by SETool2 Lite.
4. You will get a gdfs_
[yourIMEI].bin file in SETool2 Lite folder. Put it to a safe place.
I. We need to generate an unlock patch.
Run SIMLockPatchGen.exe, select the MAIN firmware (what match your phone firmware) by clicking on
... (three dots) button, then press the
Make patch button. In status window you will get the path to the generated vkp file(e.g.
"D:\...\SIMLockPatchGen\vkp\Remove_SIM_lock_XXX_XX XXXXX.vkp" patch file created.) Close the SIMLockPatchGen.
II. We will apply the generated patch to unlock the phone.
With SETool2 Lite:
1. Select your phone model.
2. Click on
... (three dots) button near
MISC files box, and select the vkp file generated by SIMLockPatchGen.
3. Click
Write SCRIPT button
4. Follow the instructions in left status window...
5. READ THIS CAREFULLY, it is a little tricky: When a dialog pop-up, click "
Yes" to remove the patch. Click "
No" to add the patch. In this case click on "
No" button.
Wait until "ELAPSED x SECONDS" appears in status window. Your phone is unlocked.
B. How to apply the generated patches to DB2020 CID52 phones:
IMPORTANT: First you need backup the GDFS. If something goes wrong you can unbrick your phone with this backup. Here is how to do:
Open SETool2 Lite v1.11.
1. Select your phone model.
2. Click on
Read GDFS button.
3. Follow the instructions given by SETool2 Lite.
4. You will get a gdfs_
[yourIMEI].bin file in SETool2 Lite folder. Put it to a safe place.
I. We will apply the quick access patch to phone. It is needed to be able to use the quick access method in future. Due to this great patch you can easily apply the further patches, just like to DB2010 CID 49 phones.
!!!YOU NEED TO DO THIS ONLY ONCE!!!
With SETool2 Lite v1.11.
1. Select your phone model.
2. In Windows Explorer drag the MAIN file (.mbn) onto

At one moment you will belive that nothing happens and the status windows is not changing!
DO NOT remove the CABLE! Wait until "ELAPSED x SECONDS" appears in status window.
This process will take some time, about 10-15 minutes or more...
II. Now we need to generate an unlock patch.

... (three dots) button, then press the
Make patch button. In status window you will get the path to the generated vkp file(e.g.
