Debrand C903 Telefonica-UK

[paulo230]

EDIT: PROBLEM SOLVED

I'm a beginner at this, but I want to debrand my C903 phone (CID53, DB3210, service provider: o2 PAYG) using SEUS method. I've been reading for hours about using a CDA file, but don't know what language codes to use. This is some of the info I got from my phone using Omnius:

MAPP CXC article: R1EA032 prg1214-6139_GENERIC_FR
Detected chipset: DB3210 'E900
CDA article: 1224-0233
CDA version: R13A
Default article: 1214-6153
Default version: R1EA032
Language package: TELEFONICA-UK

I was using SE CDA File Maker to create the customize_upgrade.xml file, but was not sure about the language setting to use so I manually created this by copying the info from Omnius:

<?xml version="1.0" encoding="utf-8"?>
<customization>
<info>
<cda-number>1224-0233</cda-number>
<cda-revision>R13A</cda-revision>
<created-by>thaproxinator</created-by>
</info>
</customization>

Can anyone tell me whether this is correct? Also, does anyone know how to make a backup because A2uploader cannot read from CID53? I'm not even sure how much it matters to use the correct codes because I can't find much info about this!

Thanks!

Eventually used the generic Western Europe (cda number 1209-4774) file in SE CDA File Maker & have SE branded phone now. Did this after I found out I could safely return to o2 UK branding by using the 1224-0233 code I mentioned in previous post if necessary. The o2 branded software caused my phone to make unnecessary internet connections & they charged a disgraceful £1 per MB. Also, the SE software contained 4 free games, but the o2 software locked several games onto my phone that I would have had to pay to use. Very pleased about all this!
