Our Xperia Unlock Software reads the original unlock code from your Sony Ericsson Xperia and enters it automatically into the phone to unlock it. Unlocking lets you use your phone on any carrier that uses SIM cards. The warranty is maintained because there is no alteration of the phone's software. 

In order to use the software, you need a license key. If you have not purchase one yet, please do it here.

Get Started

Part 1/2: Prepare For Unlocking

Before You Start: You will need a USB cable to connect the phone to the computer.
 

Check that your device is GSM. Our program only works on GSM devices. GSM devices will have a SIM card slot in the battery case (see the top right in the below diagram):



Please make sure that:

• Your Xperia is not running ANDROID V1.6 (if it is, please update your phone before unlocking. Do not attempt to unlock V1.6)
• Your Xperia is running Android 2.1 (if you have a higher version such as 2.2 or 2.3, please first DOWNGRADE. You can later upgrade again. If you need help with this step, please contact us at support@xperiaunlocked.com)
• You have a standard non modified kernal on your phone (you have not flashed custom firmware to your Xperia)
• You must have a stable Internet connection

Trouble Shooting:
 
Error message: Invalid File
 

Possible cause 1:
On Vista or Windows 7 32/64 byte OS, client must be run as administrator (right click on shortcut, select "run as administrator")

Possible cause 2:

Firewall or antivirus is deleting files in the “loaders” folder. Uninstall software turn off antivirus and reinstall.

Note: If Windows states that it did not find the required drivers when connecting your Xperia phone in Debugging Mode, please open device manager (Right Click on "My Computer" and select "Properties", then select "Hardware > Device Manger"). You will see a yellow asterisk against the "SDB Device". Right Click and select "Update Driver". Then, from the nest set of options, select "I have Drivers Browse to location", then Browse to C:\Program Files (x86)\Multi Unlock Client\adb on WIN Vista/ Windows 7 or C:\Program Files\Multi Unlock Client\adb on Windows XP, then click Next. Windows will install the drivers.

Please note the video is demonstrating the driver installation on an X10 phone, but the process is the same for all supported Xperia models.
