Flashing/debranding my C905a

[n-arov]

Hello everyone,

I am trying to debrand my SE phone, using this as a guide:
http://www.topsony.com/forum/a2uploa...tml#post107964
I installed all the necessary programs and drivers, created an .xml file (for generic American version), transferred it to phone, tried SE Update Service, no go. Says I already have the newest software.

I tried creating a new .xml file, but this time using Western Europe instead of America. Still, Update Service says my software is new enough. Then I tried going back and creating a generic American .xml and using Update Service to reinstall my OS, but that only reinstalled the old and customized AT&T OS which is what I'm trying to get rid of.

So my questions are:

1) I was sort of reluctant to debrand in the first place, but what is the worst thing that can happen if debranding fails?
2) Is there some other CDA number I can use (instead of America/W. Europe) and still be able to use my phone with my service provider? Perhaps Central or Eastern Europe?

Thanks in advance,
Nathan Arov

Did you used this customize_upgrade:

<?xml version="1.0" encoding="utf-8"?>
<customization>
  <info>
    <cda-number>1209-4760</cda-number>
  </info>
</customization>

?
Did you switched on then off the phone after uploading it ?

I used 1209-4778 for America...
... and 1209-4774 for Western Europe.

I did turn my phone on (and later off, before updating) after uploading the first CDA xml file (the American one), just to check that it still works alright. I don't remember doing the same for the European one.

By the way, I just tried using 1209-4760. Saved it on my phone, turned my phone on and off, but Update Service says my software is up-to-date anyway... :/.

Don't you have "continue anyway" option ? If you don't, flash with:
C905_R1FA035_MAIN_GENERIC_SI_RED53
C905_R1FA035_FS_WESTERN-EUROPE_RED53 and customize with
C905_1209-4774_R6A_GENERIC_WESTERN-EUROPE, using this tutorial:
