Debrand your Xperia S [Tutorial]

If you recently bought your Sony Xperia S via a mobile operator there is a good chance that it will carry some bloat compared to the sim-free variants. The disadvantage of carrier customised firmware isn’t just bloat though, there is also every likelihood that updates will take longer to hit your handset. Mobile operators need to take the time to customise firmware which could mean that new firmware could take days or even weeks longer to appear on your handset.

Luckily for you, we’ve published an easy guide for you to debrand your firmware. The process is no different to flashing older Xperia handsets, however we thought it was worth posting as there are a lot of new Xperia owners following the Xperia S launch. The instructions below will debrand your Xperia S handset to UK generic firmware. Xperia Blog absolves itself from any responsibility should something go wrong. Please proceed with caution and at your own risk.

Tutorial on debranding your Xperia S

Note: This tutorial does not require you to root your handset, it does not require you to unlock your bootloader and you will not lose your user data.

1) Install drivers for the Xperia S
The very first step is to make sure that your PC has all of the necessary drivers installed for the Sony Xperia S. The best way to do this is to install PC Companion or Sony Ericsson Update Service (SEUS). Make sure you connect the Xperia S to the PC before starting the process to download the necessary USB and ADB drivers.

2) Find your customization number [Optional]
The customization number of the handset identifies which region/carrier customised firmware your handset is running. It is best to start by noting what your existing firmware customisation number is, so that you can make sure it has changed once you complete the tutorial.

Do this by opening the dialler and press the following characters: *#*#7378423#*#*
Access Service Menu > Software info > Customization Version.

In this example we are debranding an O2 UK handset which has the customization number 1257-9042_R7E.

3) Switch on USB debugging on your handset
Switch on the debugging option on your Xperia S. Go to Menu –> Settings –> Applications –> Development –> Tick ‘USB debugging’

Also tick ‘Unknown sources’ under Menu –> Settings –> Applications

4) Install Flashtool
Download and install the latest version of Flashtool on your PC. [Mirror for North American users]

5) Download the generic Xperia S firmware
Download the generic Xperia S firmware from here (312MB). This is version 6.0.A.3.67 of the UK firmware for LT26i handsets. This tutorial will work with a FTF file from any region, so if you have a different FTF file feel free to use it instead of the UK one for this step.

A note of warning: Some browsers like Opera will rename the extension of this FTF file as a zip file when trying to download it. Make sure that the downloaded file has a .ftf extension rather than .zip.

6) Place firmware in correct location on your PC
Place the FTF file in the C:\Flashtool\firmwares folder.

7) Launch Flashtool
Open the Flashtool application on your PC. Click on the lightning bolt symbol.

Select Flashmode and click OK

8 ) Select firmware
Select the correct firmware in the left column (LT26, 6.0.A.3.67, 1257-3921). If you uncheck the “wipe userdata” box in Flashtool before flashing, you will not lose any data. Click ‘OK’.

9) Connect phone to PC
Turn your phone off. Press and hold the volume down key while plugging the USB cable into your Xperia S.

Ignore the instructions from the pop-up window as these are for a different Xperia phone.

10) Flashing process will start
The flashing process should now start and you should see something similar to the picture below.

Once you see the “Flashing finished” message in Flashtool, remove your handset from the PC and wait until the phone reboots (this may take some time so don’t panic).

Debrand your Xperia S

11) Your phone should now be debranded!
Congratulations, your Sony Xperia S should now be debranded! You can check the customisation number as per step 2 to confirm this. In this case the UK generic firmware has the 1257-3921_R5E customisation number.

    Sweet

  • Faalhaas

    Glad mine is sim-free :D

    A better idea would be to download Generic NL from here instead of the UK firmware:
    http://www.xdafileserver.nl/Xperia%202012/Sony%20Xperia%20S/Original%20ROMS%20-%20FTF%20format/ 

    It’s a lot cleaner than the UK ROM, and you can remove almost all bloatware applications. It doesn’t contain any bloat at all actually, once you’ve removed McAfee and stuff.

  • Mrpaulparker

    Does this work on the experia arc

  • ahomad hosin

    will this unlock the phone as well or it will still be locked?

  • XperiaBlog

    No, this does not remove sim lock – it only puts you on generic firmware.

  • XperiaBlog

    The process is the same – you’ll just need relevant Xperia arc FTF firmware. Check xda-developers Xperia arc development section for this.

  • XperiaBlog

    Thanks for sharing – good to know it has less bloat. 

  • http://profile.yahoo.com/Y6HHKHSPGKLSQPJ37KSSRD23CE Scorpion

    Does this work with the SO-02D ? (Xperia S/NX from Docomo)

  • ahomad hosin

    not a problem. with my current version, I can’t unlock the bootloader, will this change with the debrandong? i.e. will it be possible to unlock the bootloader after the debranding?

  • BatesOut

    Can somebody point me to a valid download link for 4.0.2.A.0.42 UK firmware for the Xperia Ray, I used Wotan to flash it with a generic 1 but I can’t find anywhere to download a copy for future use incase Wotan start charging … Thanks guys.

  • Martin Wasley

    Why is the file so much larger then?

  • http://twitter.com/AmbroosV Ambroos Vaes

    It contains slightly more apps, but all the extra apps it contains CAN be removed unlike the UK firmware.

  • Asad Mulla

     Same here. Sim free White.

  • XperiaBlog
  • XperiaBlog

    Yes. 

  • XperiaBlog

    We don’t see why not – but maybe someone else can confirm?

  • BatesOut

    Thanks so much for the reply :), I will try that  now !

  • Gene87

    I downloaded flashtool and I put the TFT file in firmwares but Flashtool doesn’t show the firmware! Also my device isn’t recognized?! Need some help please

  • Gene87

    I was using the NL generic software by the way…

  • Gene87

    Nevermind I fixed it, the file I downloaded was corrupted -_- I downloaded the TFT file again and it worked just fine. 

  • ahomad hosin

    you might need to install the drivers (by installing PCC)

  • Magicshirt

    Attempted this but got a message saying “ERROR – Cannot identify your device”. Also Flashtool can’t see the firmware.

  • Magicshirt

    Seem to have had the same problem as Gene87… it is working now :-)

  • lch

    Doea the uk firmware contain Asian input?
    Where to get generic Singapore firmware?

    good 

  • jayjay

    Thank you very much for this, does anyone know if this can be done on a WinXP pc or does it have to be a later version of Windows?  Or even a Mac?

    Cheers

  • Dio Merda

    dio scafista!!!!

  • ahomad hosin

    unfortunately, debranding my phone didn’t allow it to become boatloader unlockable. you should have said you don’t know. thanks anyway. my phone is better with all the crap removed

  • XperiaBlog

    Sorry we misunderstood your question. If a phone is sim locked or has its bootloader locked this guide will not change that. The guide will simply put you on generic firmware and nothing else.

  • jayjay

    Just done it on a Win XP laptop, so yes you can, just restart your pc to install adb driver before using flashroot

  • jayjay

    Mine still says no to unlocking the bootloader – 02 uk phone

    Hi,

    My Xperia S was purchased in China. The reason for wanting to rebrand is that I am actually British. This Chinese firmware has no Google apps. installed and when they are installed, they do not run. I do not even have access to the Google Play store. 

    If I follow the process below, will this process give me the apps. I need? I know that Google Play works on HTC phones in China so that is not a concern.

    Hi,

    My Sony Xperia S(LT26i) is Sim Locked & Bootloader Locked…

    Rooting Status: Bootloader unlock allowed: No
    Sim Lock: [x] Network 0

    How to Unlock My Phone……?

  • vince

    it works with So-02D, use latest flashtool

  • http://luk1.weebly.com/ Luki

    You cant unlock bootloader. You can unlock sim (afaik).

  • vickyboy786

    How can i lock my sim? please help me because i have the same problem.

  • http://luk1.weebly.com/ Luki

    Why would you want to lock your sim?
    If you want to unlock it then we need more info. Is it locked because of the PIN entered too many times badly?
