If you want to debrand it for free and feel a little tech minded then try this way which i found on topsony and it worked for me


First of all, i dont have any credit for this method. I was helped by several users ( Thanks ! ) and i decided to make a guide to help.

This is an A2 Debrand Tutorial

Software Required:
- A2uploader ( google search )
- Sony Ericsson Update Service ( Comes with the phone CD, or download on SonyEricsson website )
- Notepad ( Comes with Windows ... )

Note: On some Sony Ericsson Models, you have to press 2+5 instead of C.

Recommended Step: (For Users with Phone Warranty)
- You will need to identify your CDA to Debrand again your phone in case you need to take it to Warranty.
- Turn Off your phone and remove the battery and put it again.
- Connect the USB cable to the phone and Press C button.
- Execute A2uploader on your computer, and press the identify button:

- Then plug in your USB cable to the computer, and should appear a text like this:

- Save that number on CDA-Article
- Follow the next steps:

Step 1:
- You need to switch your phone CDA to a Generic CDA, this makes SEUS to update to the debranded firmware.
( for people who want to restore the phone "Recommended Step", in cda number on xml, copy the one you got from A2uploader )
