New flash tool from Sony for unlocked Xperia™ smartphones [video + beta download]

Today, we release a beta version of our new flash tool for Xperia devices, which enables you to put on standard Sony software* on a Sony Xperia™ smartphone which has the boot loader unlocked. This functionality has often been requested by the open Android™ community, and now we’re glad to support it. Please note that the phone still stays unlocked, and that the warranty may still be voided. As this is a beta version, only a limited number of phone models are supported to begin with. Read on for instructions and more information, and to find out how provide us feedback – we are really eager to hear what you think!

At Sony, we have been supporting the custom ROM community for a long time, and our unlock boot loader service is very popular. We know that many of you are advanced users, who like to try out different ROMs on your Xperia™ smartphones. But until now, there has been no way to go from a custom ROM to Sony software.

We are proud to provide high quality, stable software for our phones, and with this new flash tool, you can now flash standard Sony software on a Sony Xperia™ smartphone which has the boot loader unlocked. However, please note that the boot loader of your phone still stays unlocked.

To start with, you can use this flash tool with Xperia™ S, Xperia™ arc and Xperia™ arc S, but we plan to add support for more models going forward. UPDATE: Support for Xperia™ T added. At the moment, one software version is available for each supported phone, but our ambition is to offer a selection of software versions released for each phone. For example, this could mean that you can choose between GB and ICS releases.

This flash tool is available for most markets globally**, with a few exceptions*** due to distribution restrictions.

How to install and use the flash tool for Xperia™
To get started, you download and install the flash tool on your Windows computer. When you use it, the tool connects to a server to access the software for your phone. To download the flash tool, go to the Xperia flash tool installation page. On that page, you will also find all instructions you need to install the tool.

When you have installed the flash tool, it’s easy to flash software onto your unlocked Xperia™ smartphone. Once you have connected the phone to the computer, the tool automatically identifies the phone model and displays the available software. For more information on how to use the flash tool, go to using the flash tool for Xperia.

Note! When you flash software onto your phone with the flash tool, your user data and content will be erased. Make sure to properly back up all information.

Let us know what you think
So now you’re welcome to try the flash tool for yourself! Since it is a beta version, we are eager to find out what you think about it. Is this a useful service? And what phone models and software would you like to see support for in the future? Please share your opinion on the XDA forum, where we’ve started a thread for this flash tool. And as always, you can drop us a comment below to let us know what you think!

    Xperia Z1 is a outstanding phone, with great specs and design. Since a little kid, I was brougt to all Sony mastercraft design and quality products. Is a shame really that I need to sell my favourite phone (being a completely Sony supporter) just because Remote Play App was restricted to Z1. Why? It´s a little nonsense. Thanks in advance for all your time and patience.

    A query:
    I unlocked my boot on my xperia sony z2 6503 (version 4.4.4 kitkat) with software sonymobile, at that I’ve noticed that gained power in the sound volume, tones and music that was very low since it buy a month ago, but now when checking calmly put me quality sound, sounds loud but sound quality and heated a little camera, I really unlock because I wanted installing a MOD sound enhancement on XDA climbing the power and makes the two headphones work but to unlock the power of sound that seems excellent but low quality is improved and improvements as surround sound does not work, now my question is: if you flash with flash tool back to its sound quality it had before keeping force has now pus later upgrade to version 5.0 lollipop.

  6. By Eli Lugoe


    It needs registration and now it has been almost two days still I am waiting for activation e-mail,what is this?

    • By Anna Aleryd



      You don’t need to register to use this tool. Just make sure you have the customization.ini file in the right folder, as described in step 4 and 5 on the installation page.

    I have rooted my Xperia P phone with DoomLord Easy Rooting toolkit. The rooting was successful.

    I have modified an image from standard bootanimation, and now after restart it shows only black screen. The device is working well but I am not able to monitor anything as the screen is black.

    I have not changed the ROM. Can I still restore the phone using this flash tool?

    If not please suggest how should I resolve this issue?

    Thanks and Regards

    • By Anna Aleryd


      Hi Ashutosh,

      As long as you have unlocked your boot loader, you should be able to use this flash tool to flash Sony software on your device. However, please note that this does not restore your device to its original state, as the boot loader will still be unlocked.

      Best regards,

    I have a Sony WT19i (LWW) and had used flashtool a in the past to flash custom roms and kernels on my device. But now, ‘Flashtool’ has became ‘Emma’, and my phone isn’t supported any more. Why does Emma hate me so much? why won’t she be nice to me?

    With customization.ini in place it doesn’t ask to login, but terminates with error “Unable to login”. Reinstall doesn’t help.
