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.

#1Hello Anna,
My name is Roberto and I’m from Ecuador. I have a problem with my SONY XPERIA TL. I can not unlock the phone.
First, was completed 10 attempts to unlock it by code.
Second, the options Service info / Configuration / Rooting Status. If Bootloader unlock allowed says No.
What can I do to unlock my phone? Please help me.
By Anna Aleryd
#2Hi Roberto,
If Bootloader unlock allowed says No (or if the status is missing) your device cannot be unlocked. If you have a look in the list of supported devices, you can see that Xperia™ TL is unfortunately not supported.

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

#20Hello, I can’t see the folder named “Firmware” and I don’t know where putting the ROM. Where must I put the ROM then?
By Anna Aleryd
#21Hi,
The flash tool for unlocked Xperia™ devices can only be used to flash firmware that we provide in the tool (usually standard Sony software). This means that you don’t need to add any ROM to flash those software versions. If you want to flash a custom ROM, you have to use another tool to flash it.
