success to debrand ATT Z750a to Z750i

I was success to debrand ATT Z750a to Z750i yesterday.

First. use A2 CDA File Generator v1.01 to create customize_upgrade.xml file.
but I edit CDA code in customize_upgrade.xml file as below:

<?xml version="1.0" encoding="utf-8"?>
<customization>
<info>
<model>Z750</model>
<phone-name>Z750</phone-name>
<cda-number>1201-6491</cda-number>
</info>
</customization>

then run program A2UPLOADER to put customize_upgrade.xml into tpa/preset/custom

Finally, run Sony Ericsson Update Service to upgrade new firmware.

CDA# 1201-6491 is Customized Indonesia. The firmware come with English & serveral Asian Language

good luck:)

sorry, forget 1 step.

After, upload customize_upgrade.xml into phone. you need to turn phone power on, and then turn off.

Then go to run Sony Ericsson Update Service

glad to hear your success

v1.03 is out and soon i will release v1.04 with more cda options ;)

thank you so much doaremon....this worked perfectly!

Worked successfully for me, too... Thank you very much for sharing the procedures...

Doaremon,

What cable did you use to upload the xml files and where can I buy one?
I am trying to change the phone to Chinese.
Thanks.
