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.

    Is there a way to download services for D6603 through Emma? Mine has shown the same service available for some time now, 23.4.A.1.200 and I know the lastest firmware is 23.4.A.1.264 for my device. I have updated Emma several times.

  8. By Irfan Shaikh


    I have installed EMMA twice now and every time i get: “An application error has occurred and the application will exit. Unable to login”
    I uninstalled, redownload, copied the customization.ini file to the Emma folder and I get this every time.
    I am running Win7 32-bit and also tried on Windows 8, I also have an active internet connection.

    Any Help???

    What a shame there’s still no services/support for Xperia J. My mobile is stuck (can’t login; no keyboard support due to Google search crashed message) and I tried everything: can’t hard reset (tried various button combinations at restart but nothing works), and Sony PC Companion can’t help either since the keyboard doesn’t work so I can’t login. I unlocked the phone. Why is it so hard to reset a phone? I can format a PC by replacing a hardrive 🙂 Help?!?!

    Iám using a Z3 Compact Device (D5803), i get everytime the message from the flash tool:”No availabe service matched the connected device”. The Device bootloader is unlocked and i update the Device twice times bevor without problems with the flash tool!So what can be my problem?

        I have sent your comments to our support team, who are looking into the reason behind this. So far, we haven’t found any issues on our side, but we’ll keep looking.
