3. Sony has done something to block this CDA trick in new firmwares or models

1. If there is so, I will keep trying untill SE has an update..
2. In Service menu (>*<<*<* ) program info, can I see the number in the CDA I entered - is that a sign on a successfully uploaded file or how can I else read files in the phone?
3. This idea has struck me, if so, someone out there who succeeded with this method? report phone model, any G502?

Thanks for all help sofar bboyzahid!

Guide for those who have a branded W910i that the branding blocks the customize_upgrade.xml method:

Step 1: Downloading required stuff
1. Download/extract/install Sony Ericsson Update Service
2. Download/extract KulanKendi Client
3. Download/extract A2 Uploader
4. Download FS - see download area
5. Download MAIN - see download area
6. Download and extract the costomization file
7. Run DPInst from the "USBFlash_driver" folder inside A2 Uploader. All drivers is now installed.

Step 2: Debranding the phone
8. Turn off your phone (KulanKendi Client advises Master reset first)
9. Run KulanKendi Client and type anything in the login/password fields.
10. Select the "DB3150(A2)" button (make sure that all boxes is UNTICKED
11. Select the "Open file" button beside "Main" and navigate to the MAIN file you've downloaded above
12. Select the "Open file" button beside "FS" and navigate to File System you downloaded above.
13. Select the "Flash Phone" button.
14. Hold the "C" button and plug your USB cable into your PC and then your Phone.
15. "MAIN" file will be flashed (will take 3.5 minutes).
16. "FS will be flashed" (will take 2.5 minutes).
17. It will say "connecting" or something similar then it will say "unable to connect" or something. This is OK.
18. Close KulanKendi client, let go of the "C" button and unplug the phone.
19. Run A2 Uploader.
20. Click on "File System Tool", and hold the "2" and "5" buttons then plug USB cable into the phone.
21. Once the file system on the right has appeared, let go of the buttons and navigate to tpa\preset\custom and then drag "customize.xml" onto the file system window. This takes a second or two, when it's done, stop the file system tool (by clicking on "Shutdown FS Manager"), then quit the application.
22. Turn on your UNBRANDED and "new" phone.

The guide worked perfect for my W595.
Thank you :)

Just debranded my Vodafone branded W595. It was soooo annoying, now is so much better!
I used this .xml file:

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<customization>
  <info>
    <cda-number>1201-0083</cda-number>
    <language-variant-name>ADRIATIC</language-variant-name>
  </info>
</customization>

SUPER THANK YOU !!!! :cool::D

cant download a2 uploader ive tried many sites and i always get the same diagnostic messages:
! C:\Documents and Settings\Owner\My Documents\Downloads\a2uploader (2).rar: CRC failed in a2uploader.exe. The file is corrupt

! C:\Documents and Settings\Owner\My Documents\Downloads\a2uploader (2).rar: Unexpected end of archive

You have to disable antivirus, cause they give false alert.

You need to upload custom files with a2uploader to phone

I can only confirm that it works on a W595 which was proximus/vodafone branded in Belgium. Just entered the '1201-0077'-CDA and it works. I got finally rid of the vodafone-Live stuff!

Thanks!!!!

Hey guys

Does anyone know if this debranding method will work for upgrading to a different firmware from a different country and thus get the language too?

Ie. I am from Canada using a Rogers phone with English and Canada, if I debrand to Hong Kong then I will get Chinese and English?

Thanks

It should work. But, with the new A2Uploader, you can flash any A2 firmware. Search in the download section for a "generic" MAIN and a "hong-kong" FS.

Yupiiiii!
Thanks my friend..... It worked perfectly to me.....
Now my new W910i has European firmware... it had Hong Kong version software and only English T9 dictionary...
Now it's simply perfect!

All my best!

Hi Guys

If anyone is getting a screen where no option is given to reinstall and SEUS simply says
" Your software is up to date" THis is most likely because you have a wrong CDA

Follow all the steps outlined by original poster, and if you have any troubles, try one of these CDA's

CDA/CDF List (A2 phones only) - myForum

credits to wrox at lasyk forums

A2 CDA File Generator v1.05 **X-MAS RELEASE**

added wrox's cda lists

Hey I recently had my c905 unlocked and I just noticed its certificate is Brown! I tried with my Red k850i and it worked. I read somewhere that SEUS dosen't work with brown so could that be why "no update available" come up?? Is there any way to change it to red? Help is apperciated :)

Can anyone help me with my k850i to debrand it :( but please with photo !!http://img135.imageshack.us/my.php?image=k850iry1.png

Does it matter which firmware i want to update too? Eg i'm using generic south africa at the moment. If i flash too another one eg. Asian pacific firmware. . . Will my phone still work like it should concerning network etc?

Of course, no problem as long as it's the same model firmware!

Read this tutorial.

hello,
i have the SE C902.

would you be able to help me if possible it is on orange contract and i would like to remove there stupid menus and replace with the standard SE ones is this possible and if it is possible would this process work for mine

thanks for any help!!

Yes, this will work for you, too. Connect your phone to a2uploader and copy here your phones log without IMEI number.

Have a nice day

I've spent the whole day trying to rebrand my W910i Vodafone UK to something generic.

The SEUS kept telling me that the software was already up to date and didn't give me any option to reinstall it.
Turns out the reason for this was because my phone was already using R1FA036 for which many generic versions don't exist, so I had to downgrade to some random R1FA035 before changing the CDA to the one I wanted.

Maybe this information will save someone some time :)

Thanks so much! I had picked up a C905 for the wife, but it was the wrong language. Your instructions were perfectly clear and I was able to set up the phone for HK without a hitch.

Brilliant!

Hi thanks a lot fianally got rid of that o2 branding off my w760

and btw this the customize_upgrade i used

<?xml version="1.0" encoding="utf-8"?>
<customization>
<info>
<cda-number>1201-0077</cda-number>
</info>
</customization>

Thanks for the post, it's brilliant, i just debranded my k850i from 3 network, thanks :)

First of all, thank you very much for that manual.
I searched in a bunch of forums and it took me at last 4 days to find that forum entry.

I've done it exactly the way you described. and up to now it all worked fine. I am now, at this moment, updating my software on my phone, and it seems to work great. i will edit this post when it's done and working ;)

but first I have one question.
Does it still cause problems using A2uploader when having a master reset as it says in the faq4mobiles.de forum?

Und bitte nach der Anwendung des a2uploader keinen master-reset machen, dies könnte zu Problemen führen.

I got my phone brand new and I really don't want to demolish it now :-P

i used the following code for the customize_upgrade.xml:

Quote:

---

<customization>
−
<info>
<cda-number>1201-0116</cda-number>
</info>
</customization>

i've bought my phone @ o2-online_shop with a o2-branding preinstalled, which is really annoying.
Oh ... at least i've forgotten to tell ya where i come from and which blablub i use(d):
i am from germany and i used some central-europe firmware.

EDIT! :

IT WORKED!!! GREAT JOB!!!
THANK YOU VERY MUCH!
i did not let myself confuse by the pop-up in SEUS while updatin':
...reinstall your old software...(it was something like that)...

:)
lovely!

Hi everyone :)

I've just debranded my VFL W910i and it works ok at the moment :D

I only have one problem :confused:

I'm from Greece and the cda that I used is "1201-0138 S-E-EUROPE GENERIC S-E-EUROPE"
but this doesn't support Greek :(

Does any know which cda I have to use so that it can support Greek :cool:

Thanks in advance :)

Thank you Thank you Thank you Thank you Thank you Thank you...!!!

Finaly got my c905 debranded, I had to covert to erom colour from brown to red and it updated. I think this was the cause of my no update available but it might be something else in other peoples cases;)

thanks a lot for this guide!!!

debranded w980 now :)

I ve just managed to debrand a W910i From Greek Vodafone!!!

The CDA number I used is: 1201-0083

It contains Greek language!

Thanks a lot for the GREAT guide!!!
(I thought it would be much more difficult...)

it worked but it killed my K850i. Now the "c" doesnt respond when connected to A2uploader and when i hold 2+5 i cant upload files or flash firmware. soemtimes a red light appears at the top randomly. any way to repair it?

Did your phone battery was fully charged before you try to debrand phone (maybe it's empty)
