De Brand your A2/db3150 Sony Ericsson phone

Alright finally A2 (db5150) debranding after all the adventures with db2020/db2010 !  Now this is the tutorial to de-brand your A2 phone and get rid of the branding ! And get a neat and clean phone without any restrictions. By de-branding all the restrictions imposed by your operator will be removed. Well but kindly note de-branding is not unlocking. Your phone will still be locked. To unlock your phone, check out the Aerix Tool.

A2 phones are C510, C702, C901, C902, C903, C905, G905, G705, K630, K660, K850, K858, T700, TM506, V640, W595, W705, W715, W760, W890, W902, W908, W910, W980, Z750, Z770, Z780 ! So make your sure phone is in this list. We will update this list as and when new phones are released.

Necessary stuff. Download all of them.

There are 2 ways to de-brand your phone.

1.You can use change your phone CDA and use SEUS to update your phone.
2. Else you can directly flash firmwares of your choice using A2uploader.

The first method is recommended for new users. And 2nd method for advanced users. My choice would be the 2nd method.

1. Using CDA Hack to de-brand phone.

To de-brand your A2 phones, you need to know how to use A2 Uploader !  We will use A2 uploader to upload the de-branding files to your phone’s protected file system.
You can manually create the de-branding file or else you can use CDA Generators  ! I recommend new users to use the tool created by CodeClaw or by thaProxinator, that should make your life easier. Also make sure you have enough space in your phone memory, so that we can upload some files to it.

Part 1

  • Download a CDA Generator.
  • Then start the program in Administrator Mode in VISTA, if XP then just open it.
  • Select your phone, region and click generate XML.
  • You will get a file with name customize_upgrade in your CDA Gen folder. Keep that file.

Part 2

  • Now start A2 Uplaoder
  • Click File System in A2 Uploader
  • Connect the phone to USB via  A2 Uploader holding the keys 2+5 !
  • Don’t leave 2+5 until A2 uploader detects your phone and starts.
  • Navigate to tpa/preset/custom/
  • There you will find 2 files, customize.xml and preloaded_config.xml
  • Right click on these 2 files and click Read. This way you have a backup of your old customization.
  • Then Upload the Customize_upgrade xml file to the phone file system —
  • — In  directory tpa/preset/custom in the phone.
  • Now Shut Down the File System Manager in A2uploader. Dis-Connect, Re-insert battery,  Start phone for CDA changes to happen.

Start your phone now, wait for some time, then later you can shut it down. You won’t find any changes yet. Don’t forget to backup all your contacts, pictures and every thing important to you. Use MyPhoneExplorer to backup things that you may need. Better safe to backup up then sorry.

Part 3

I hope you have installed Adobe Flash Player ! If YouTube works for you then you certianly have installed Adobe Flash Player. Else get it from Adobe Website.

Download and install SEUS. And Start SEUS. Then update your phone via SEUS. Using SEUS is very easy, all you need to do is follow the on screen instructions. SEUS is very pretty program to use. Its made in Flash. It will download firmwares from the internet and flash your phone according to the new information in customize_upgrade file. The customize_upgrade specifies generic firmware for your phone, along with correct region code. So make sure you selected correct Region in CDA Generator, else you will face language problems later. Update the phone. That ends the de-branding process.

If this method is not working for you and if SEUS says Phone is Updated and having latest firmware, then flash firmwares manually, in short use the 2nd method.

2. Flashing Firmwares to de-brand.

Just go to topsony or seusers and download the firmwares that you want according to the language of your choice. And flash the firmwares using A2uploader. See the a2uploader video tutorial provided in the a2uploader tutorial, it shows how to flash firmwares. That should be it.

3. Re-branding your phone.

Lets say you want to re-brand your phone back again, Then all you need to do is, open the customize.xml file and note down the cda numbers in it and copy it into a customize_upgrade.xml and upload it back to phone and then again update it with SEUS. Its as simple as that. The newer versions of CDA Generators also support re-branding, check it out too.

Now all the features of your phone should work ! Also you should now be rid of all operator crap. You can download settings, if missing from sony ericsson website. Enjoy your de branded phone.
