Xperia Z DebrandThe following guide will help new Sony Xperia Z users to debrand handsets to generic unbranded firmware. The advantage of doing so is likely to mean faster firmware updates given that carrier customised firmware normally adds unnecessary bloat.

The process of flashing the handset via Flashtool (courtesy of xda-developers) 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 Z

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.

PREPARATION

1) Download and install Flashtool on your PC from here (Linux / Mac).

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 one of the following:
[C6603] Generic Nordic 10.1.A.1.434
[C6603] Generic UK 10.1.A.1.350

If you can source a different FTF for your region, you can use that instead of the above files. However, the above files will work on any Xperia Z (C6603) 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.

5) Select firmware
Select the firmware that you have downloaded in the left column. If you do not want to do a clean install ensure ‘Data’ is not ticked. Press the ‘Flash’ button.

Note: For the Xperia Z, 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 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).

    You’ve got to be kidding. STOP with “where is the JB for XS?” Sony DOES NOT read the blog. Stop with that annoying complaint

    I have sony Xperia Z, but the camera resolution is up to 12mp only. Other than that every feature is really good. am i using a authentic Xperia Z?

  • http://www.facebook.com/billythefretes Billy de Fretes

    12 MP only when superior auto and HDR is enabled

  • http://www.facebook.com/billythefretes Billy de Fretes

    can it works with C6602 model? since xperia z in indonesia only C6602

  • SonyFan

    You’re on Superrior Mode right? Go to Normal Mode and select 13MP…if it is still 12Mp… Then put HDR off

  • aira martinez

    Big Thanks for the help. :) i’ved been thinking about it for almost 9 days since i got my Xperia Z. :) thanks again. ^_^ Take Care.

  • aira martinez

    Thanks. ^_^

  • Mung

    I bought the phone SIM free but am on 02 (uk). Would I still have to wait for their bloatware or is it effectively debranded?

  • Hannad Ahmed

    Key lime pie for xperia z … when ?

  • XperiaBlog

    It will already be debranded so no need for this!

  • XperiaBlog

    If you can find the appropriate C6602 firmware then use that with the steps in the tutorial. XDA-Developers is a good place to start.

    Does the phone have to be sim unlocked?

    Newbie here, can someone explain why would I want to ‘Debrand’ my Xperia Z?

  • Dime

    Hahaha

  • Dime

    The problem is that the topic isn’t about that I’m also waiting for the update and I’ll wait …when it will be released than i’m going to judge about changing the company Sony to HTC or Samsung or stay close with Sony as somone writing that with this update we will get special futures with vanila project:)

  • http://www.facebook.com/kodjo.mmusic Kodjo MMusic

    ill tell sony on you debranders – maybe i’ll ge a snitching fee

  • XperiaBlog

    Not at all. It will work with any handset.

  • ZeroCools

    Doesn’t matter if you swap to HTC or Samsung or LG, they all have devices where they either slowly update it due to carrier bloatware, mostly in the U.S, or just stopped updating the device. If you really want updates swap to Nexus, buy a new phone, flash custom roms from other people, and or wait.

  • Diego Agudelo

    Thanks for this! I’ll buy a Z next week and I was waiting for something like this. Coming from a S3, we didn’t have to worry for bl or flashtool…. Kinda noob with this tools.

    Do I have to unlock bootloader for this? Do i need root?

    Thanks in advance.

  • http://www.facebook.com/bob.koh1 Bob Koh

    From reading the posts here, ‘Debrand’ seems to mean to SIM-unlock the phone. Please confirm, anyone.

    key lime pie for galaxy s 4 .. when?

  • http://www.facebook.com/kodjo.mmusic Kodjo MMusic

    thenu can get the hone as it waswhen it came from sonybefore the carier branded it. when they brandthe phone they minimize itscapabilities, debranding can undo this process,however , i thinku lose waranty

  • XperiaBlog

    No to both – it’s in the tutorial!

  • XperiaBlog

    No it does not mean sim-unlocking. It simply relates to replacing carrier-optimised firmware with generic unbranded firmware. It will not remove sim lock.

    so how do i know my xperia z is branded? got it with a t-mobile contract, but not using the sim that came with the contract. And as far as i can see there’s not a single t-mobile app installed on my xperia z. I got the xperia and my brother the contract and uses the t-mobile sim on another phone

  • Lusoelay

    So Thank You!!!!!!!!!!!!!!!

  • CW Chow

    honeycomb for xperia x10… when?

  • XperiaBlog

    Did you buy your Xperia Z directly from T-Mobile? If so, it is likely to be running T-Mobile firmware.

  • http://twitter.com/jctweeters James Chadwick

    Where would I save the FTF to if I’m using a Mac? Thanks

  • http://twitter.com/jctweeters James Chadwick

    Found it .

  • ishy

    Speaker on xperia z is too low? Especially after taking it out of water? Any one else having this problem? Any suggestions on how to increase volume? Thanks.

  • http://www.facebook.com/dennis.htc Dennis Htc

    i bought it online through a webshop, but they had 2 Xperia Z black versions T-mobile branded and unbranded. They told me i would get the T-Mobile branded, but there’s no bloatware on it, nothing that points to it,it is a branded version. And already updated to the new firmware version through Sony. Maybe they sent me the unbranded version. The invoice does state T-mobile branded Sony Xperia Z though

  • http://twitter.com/iAmDJSilentG djsilentg

    does any have a link to the C6603_Generic_Uk_No_Branding.ftf file so i can download it for free

  • Brad

    I tried flashing the Generic UK firmware to my Docomo SO-E2 but I keep getting a “No loader found for this device” error. Any ideas what may be causing that?

  • http://www.facebook.com/mark.ardagh Mark Ardagh

    Does running a debranded firmware update on a xperia z stop possible future over the air updates from coming through??

  • Gonzo

    if the phone is sim locked does it remove sim lock ?

  • Iwanova

    key lime pie for iPhone 10 … when ? :(

  • http://www.facebook.com/jarrod.hazelton Jarrod J Rod Hazelton

    1 issue. It says to press the back button while plugging the usb cable in. The xperia z doesn’t have a back button to press

  • http://www.facebook.com/jarrod.hazelton Jarrod J Rod Hazelton

    its ok i read the volume down button

  • http://www.facebook.com/jarrod.hazelton Jarrod J Rod Hazelton

    It isn’t installing the drivers to my computer. Anyone else have this issue

  • metrophobe

    in all my ignorance does this procedure screw the bravia engine and DRM keys or does everything still work properly?

  • Metrophobe

    any reason why my old comment was removed? please? I just asked a straightforward question. Does the bravia engine get screwed when using this method ? Also do the DRM keys get lost when using this flashing method? Or does everything still work correctly? Sorry for re-asking but am really wondering what this bootloader unlocking does tbh.

  • Metrophobe

    you got to be kidding right ? I’d stitch your ass if you do.

  • http://www.facebook.com/jboler James Boler

    Care to share? Wondering the same…

  • minty075

    Shame the link for the C6603_Generic_Uk_No_Branding.ftf file doesnt work unless you wonna pay for premium services…. unlike the generic nordic file which is free.
    Anyone know a working free download link for the uk c6603 file??

  • minty075
  • Nard

    What if I use an unbranded stock rom for a different country, for example the AUS one found here: http://forum.xda-developers.com/showthread.php?t=2240614 will the effects still be the same? What are the differences between the AUS stock and the UK stock?

  • http://www.facebook.com/usama.aziz90 Usama Aziz
