Xperia Z2 Debrand_0If you recently bought a branded Sony Xperia Z2, then you might be wondering how to debrand the handset to get rid of any bloatware. Asides from bloatware, generic firmware typically gives you faster updates compared to carrier customised firmware. We have created the following guide to help you debrand your Xperia Z2, it is a very simple and quick process.

Flashing the handset via Flashtool hasn’t changed for a long time, however whilst the process is likely to be familiar to many regular readers, the guide will hopefully help those new to Sony Xperia smartphones. The instructions should be self-explanatory, although if you do have any questions let us know in the comments below.

Guide to Debranding your Xperia Z2

Disclaimer: Please read the following instructions thoroughly before attempting to flash your phone. Xperia Blog absolves itself from any responsibility should something go wrong. Please proceed with caution and at your own risk.

Note: This tutorial does not require you to root your handset nor does it require you to unlock your bootloader. FLASHING YOUR HANDSET DOES NOT VOID YOUR WARRANTY.

Xperia Z2 Debrand_0

In the following example we will be debranding an Xperia Z2 running Three UK firmware to UK Generic firmware.

PREPARATION

1) Download and install Flashtool.

2) Enable ‘USB debugging’ on your handset: Settings > Developer options

3) Enable ‘Unknown sources’ on your handset: Settings > Security

FLASHTOOL GUIDE

1) Install drivers for your Xperia handset
The very first step is to make sure that your PC has all of the necessary drivers installed for your Sony Xperia. The best way to do this is to install PC Companion or Sony Update Service (SUS).

Make sure you connect your Xperia to the PC before starting the process to download the necessary USB and ADB drivers. If you have any problems you will find the necessary drivers once you have installed Flashtool in the following location: ‘C:\Flashtool\drivers’.

2) Download the firmware

Download the following FTF file, which will debrand your Xperia Z2 to UK generic firmware:
[D6503] Generic UK 17.1.A.2.55 (1282-0226) [Thanks iRimas!]

You can source a different FTF for your region from XDA-developers. The above file will work on any Xperia Z2 (D6503) handset and provide numerous language options.

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

4) Launch Flashtool
Open the Flashtool application on your PC.

Click on the lightning bolt symbol. Select Flashmode and click OK.

5) Select firmware
Select the firmware that you have downloaded in the left column. If you want to keep all of your existing apps and data, please ensure ‘Data’ is not ticked. Press the ‘Flash’ button.

Note: For the Xperia Z2, internal storage and data storage are in the same partition. Therefore wiping data will erase everything including media. As a precaution, we recommend backing up all content.

6) Connect your Sony Xperia to the PC

Once you press the Flash button, you will see that Flashtool is ‘Preparing files for flashing’.

When you see the prompt below you need to connect your Xperia handset to the PC. Turn your phone off. Press and hold the volume down button while plugging the USB cable into your Xperia.

7) Flashing process will start
The flashing process should now start.

Once you see the “Flashing finished” message in Flashtool, remove your handset from the PC and restart it (this may take a few minutes so don’t panic).

8 ) Your Xperia Z2 should now be updated
Congratulations, your Sony Xperia Z2 should now be running debranded firmware!

In our case, we debranded an Xperia Z2 running Three UK firmware to Generic firmware. You can check if it has worked by heading to the Service Menu (*#*#7378423#*#*). Then click on “Software info”. The “Customization Version” highlighted below shows the firmware build you are now running. In this case, Customization Version 1282-0226 is Generic UK.

    My Xperia Z2 was stolen a few weeks :( So sad men !

  • Dyaa Ibrahim

    ? ? ? ?

  • Jonfensu

    Wow! Where are you?

  • RyanTunechi

    Does this work on the Xperia Z to?

  • Ado Kanashii

    Im sorry to hear that bro…

  • John Zakaria

    Yes it does but you should get an firmware designed for the Xperia Z

  • kjmok

    ‘debrand’ sounds so weird. Should be ‘unbrand’?

  • Riyal

    Shouldn’t the guide include a proper backup of your current firmware first? I don’t think any carrier would honor the phone’s warranty if they won’t see any branding on your phone when you return it for warranty?

  • Camilo Uribe

    In Colombia, first my Z1 and one month later the Z2, I hate the thieves with all my soul ! :(

  • bpeo.kkp

    Will bootloader unlock VOID WARRANTY of my Xperia Z C6602

  • Hamed Azizi

    Don’t buy anything. Wait for Z3.

  • mashooo

    U must went to India :P

  • j-rod

    Debrand is technically correct because the phone was once not branded. Unbranded would be taking the brand away when it was always branded.

  • Ahmed Noori
  • jag

    i know how you feel. My Z got stolen too but im still paying for it until now. saaaaaaaaaaaaaaaaad……………

  • XperiaBlog

    Yes, but this is not required here.

  • XperiaBlog

    Technically yes, but the instructions for an average person to do so would require another tutorial.

  • Mathur Panangipalli

    U can’t write a proper sentence. let alone throwing dirt on a nation. Hold on son, let people with brains attempt humour

  • Camilo Uribe

    I’m still paying the Z1 and Z2, so so so so sad :(

  • Camilo Uribe

    I will, august right?

  • jag

    woah… i thought i was already unlucky. hehe! we had such pretty devices that’s why they got stolen.. haha!

  • Jonfensu

    No hombre… lo siento… Pero lo atracaron o dio papaya? Toca es comprar uno normalito cuando uno salga solo o a zonas peligrosas. Yo lo entiendo porque la inseguridad en Colombia, sobretodo en Bogota esta grave

  • Marius Florian

    Can you flash a ftf also if your Z2 has bootloader unlock not allowed? Because I have read in other forums that it could get soft-bricked if you flash an unbranded ftf with bootloader unlock allowed.
    Thanks in advance.

  • christere

    Am I tired or an idiot or both if I can’t find any Developer’s option on the Z2?

    Hey, can you please provide me with a link to the 3 UK firmware you have in picture above, I searched all over XDA for it and couldn’t find it, I need to get my phone in for repair under warranty and I hear you need original firmware for the warranty to be valid. Thanks in advance.

  • Ryan de Leon

    what if the phone is sim/network-locked to a specific carrier and I flash a generic firmware, will the generic firmware also remove the sim/network-lock?

    Thanks so much bro!!! Really helped me out, FINALLY CAN GET MY PHONE REPAIRED :)

  • Manny_el_portu

    Does anyone know if I have to be on a specific version of the firmware or if I can do this on the lates 17.1.1.A.0.402 version?

  • Elliander Eldridge

    Will the DRM keys remain intact? Or will I have to backup the DRM keys before I can do this?

  • Elliander Eldridge

    Two very important questions:

    1.) Will this guide work with the Xperia Z2 Tablet?
    2.) What happens if you install an update for a different model? For example, here is an FTF for SGP521, but I am on SGP561.

  • Bioback

    So basically If I download the firmware of my phone company and flash it again I’ll have zero problem with warranty right?

    I know this is an old post, but will this work on a Xperia Z1. It probably will, but just want to be 100% sure. Thanks.

  • bimi

    If you want to.flash your phone.you have to unloch your bootloader first and yes it will Void Waranty unlocking bootloader i habe an xperia z2 D6503 and i would do this if the warranty would not avoid.. So wait a little longer for the update and dont risk bricking your phone or voiding the warranty :)

  • Tunisia

    I created my own ftf file and flashed it using flashtool everything is working good model Z ultra c6833 if anyone want the FTF file of the c6833 post a comment below

  • Jadin

    Yes it will, you just need to get the right FTF file for your device

  • ChilliPSco

    I know my post was 2 months ago, but I did it. Thanks for the reply though Jadin :)

  • Tina

    Please help, I did this with xperia m2, everything worked up to the point “Flashing finished”, I disconnected my phone and turned it on and now it has been stuck on T-mobile welcome screen for an hour. Is it bad or should I wait? Thank you.

  • Cameron Burrill

    Just a quick note to those getting a 404 page from the Flashtool link;
    Either google Flashtool, go to the website and download from there
    Or in the URL replace ‘download.php’ with ‘downloads.php’

  • Leandros Komninos

    A question or two:
    I want to debrand my Z3+ (O2 UK) 1296-0227_R11A
    have found ftf generic UK but 1295-7703, will this be okay?

    secondly i can’t put it into flashmode!

    poweroff>volume down + connect USB ( debug and unknown sources checked). have also tried fastboot, no joy.

    Also in PC Companion doesn’t show ‘repair firmware’ under handset model!
    Had Z1 and that was easy to flash.
    Thanks in advance

    oh, and also aren’t you meant to exclude TA, too?

  • bryan

    man, i did the same,,,the only wrong thing we both did is how you connect the phone to usb…connect first your usb cable on the usb port on your pclaptop,,then press volume down(powered off phone) + connect the usb cable to your phone…damn sure it will do the work..it happened to me as well…goodluck!

  • 3_nity
