Unlock boot loader

Sony’s Unlock boot loader service now improved

If you’re an open source developer working with custom ROMs and kernels, or if you’re part of the custom ROMs community, we have some great news for you. As yet another step in our strive for openness, our Unlock boot loader service is now re-launched with improved usability. It will now be easier to go through the steps it takes to unlock a device.

Three main steps
With the re-launched Unlock boot loader  solution, you now have to go through three main steps to unlock the boot loader:

  1. Select your device and enter an email address.
  2. Submit your IMEI number.
  3. Get your unlock code and perform the actual unlocking of the device.

We’ve also improved they way you check whether a device is supported, we’ve revised the instructions, and we’ve made sure you’ll only get the information relevant for your particular device all the way through the unlock process, without having to browse through a lot of information applicable for other devices. In addition, we’ve also added an FAQ section, for your convenience.

Why not go to unlockbootloader.sonymobile.com and take a look yourself?

Important note
As usual, we do not recommend you to unlock the boot loader unless you are an experienced developer. The original Sony software installed on your device is rigorously tested for great functionality, which means there is no need to unlock the boot loader for normal consumers.

If you do decide to unlock the boot loader, you should be aware that unlocking the boot loader may void your warranty of the device. Certain functions or features might cease to work, and you might even cause damage to your device.

All this, and a number of other important aspects, are available on the Unlock boot loader page. Make sure you read and become aware of all of it, before you proceed unlocking your device.

      Hi,

      I am happy to tell you that Xperia E4g has now been added to the supported devices list, and you should be able to unlock it. Just remember to make sure you understand the risks involved!

      Hi Shibu,
      If the device is not on the list, then it is considered not officially supported.
      Best regards,
