Tutorial | Debrand/rebrand A2 Platforms In 3 Easy Steps Options

[thaproxinator]

Hi everyone.

This is my tutorial on how to debrand/rebrand Sony Ericsson A2 platforms in 3 easy steps with 3 simple programs.

MAKE SURE YOUR PHONE MEMORY IS NOT FULL, BACKED UP YOUR CONTACTS TO SIM AND EVERYTHING YOU NEED IS BACKED UP. REMOVE YOUR SIM CARD AND MEMORY CARD FROM PHONE.

First you are going to download three programs and have them ready for use. These are:

-SE CDA File Maker by thaproxinator (me) http://thaproxinator.co.uk/
-A2uploader by laser http://rapidshare.com/files/216770934/a2uploader_v3.rar
-SEUS by Sony Ericsson

-.NetFramework by Microsoft (if you don't already have it) http://www.filehippo.com/download_dotnet_framework_3/

Create the XML file

SE CDA File Maker creates a "customize_upgrade.xml" which contains information that tells your phone that it needs to add it to the GDFS. In this case, it is a CDA change/upgrade. The following steps will tell you how to do this:

1. Open SE CDA File Maker. If you get an error saying "the program could not be initialized", you will have to install ".NetFramework 2.0" or higher.
2. Select your model.
3. You have three options;
a) Select a region and it will generate a default GENERIC CDA.
b) Leave the region blank and enter a CDA.
c) Click ">>" on the right-hand side and select a CDA from the CDA List.
4. Enter a CDA Revision. (optional)
5. Click "Create XML File". "customize_upgrade.xml" will be created.

You are going to need this file for the next step.

Upload "customize_upgrade.xml" to your phone and make the CDA change

So you have generated the file and you want to get on with it? Well I'll make this as short as possible.

1. Open A2uploader.
2. Click "FileSystem Tool". Re-insert the battery of your phone then connect your USB holding '2+5' keys. Release keys '2+5' when A2uploader detects your phone.
3. Browse to "/tpa/preset/custom/". Drag and drop the "customize_upgrade.xml" file to the right pane of A2uploader.
4. Click "Shutdown FS Manager".
5. Disconnect USB cable and turn on phone. You will notice a "Please Wait" prompt. This is when the CDA is changing. When the prompt is gone, turn off your phone.

Finally debrand/rebrand your phone

OK, this is the last step which is the easiest.

1. Open SEUS.
2. Follow the prompts.
NOTE: See the Question and Answer below if SEUS tells you that there is no update available.

If all goes well, enjoy your debranded/rebranded phone!

----------------------------------------------------------------------------------------------------------------------------------------------

Q: I have made the CDA change but SEUS shows "No update Available". What could be causing this?

A: This is a problem that many people have when doing the CDA trick for debranding/rebranding purposes. First you need to diagnose the problem.

Two things to check are:

a) Did you copy the "customize_upgrade.xml" to the directory "tpa/preset/custom"?

b) After uploading "customize_upgrade.xml", did you turn on the phone to complete the CDA change (happens when you see the "Please Wait" screen)?

Then if you are still encountering this, it could be either of the following:

a) The CDA Revision you have used is incorrect or is not earlier than the latest revision for the latest firmware that is available on SEUS.

Solution:

Simply try a different CDA or CDA Revision.

b) The current firmware on your phone is the latest (e.g R1FA037)

Solution:

Downgrade your firmware (e.g. R1FA037 to R1FA035) then make the CDA change again.

c) Your EROM color is not RED (e.g. BLUE, BROWN etc.)

Solution:

Unlock your phone first with Aerix. Aerix will automatically change the EROM color for you to red as it needs to do this to complete the unlock. After you have done this, you can now debrand your phone. This does not apply to platforms lower than DB3150.

d) SEUS is detecting your CDA not the way you want it to.

Solution:

Try connecting with 'C' instead of '2+5' or '2+5' instead of 'C'

NOTE: If you SEUS tells you that there is no update available you will have to start over choosing a different CDA.

If there is only one CDA suporting my language? (Swedish in NORDIC), I dont want to end up with a telephone without it?
What other CDA can I try?

what customize.xml that i have to put for my w910i?

[Taikira]

Nice stuff, really. Thanx!

One thing I don't understand: if I want to add a new CDA number (for W595 orange Fr); I just have to edit the W595 list with the correct number, and the soft will be able to generate automatically the good file for the Orange Fr CDA (so I will be able to rebrand my phone if necessary)?

In the case I'm correct, my phone indicates:



and then:



So what is the correct number?

- edit -
Found myself the answer: it's yes. and the CDA N° is 1216-2249

- edit N°2 -

the trick doesn't work with my W595s. CDA for Fr generic should be wrong...
If somebody has another CDA ref for Generic France, please could you post it?

very nice... !! also really good job with the program.

[dispi]

Does this still work? I keep getting "No update available" no matter what CDA I put on, and I really hate what Orange have done to my w595.

[edited] never mind me I did it!

yes, use a2uploader to read your customize.xml. the file will be saved in a folder called "ph_out"

uhh, i dled a2uploader and once i extracted it avg detected it as a virus.
what's "ggsetup" ?

avg is false detecting it. a2 uploader is not a virus. disable your antivirus to continue debranding.
ggsetup.exe is a simple installation file which installs the usb flash drivers for you so you can connect your SE phone in flash mode
