Sony Xperia Bootloader - Unlock Tool Download

Use this guide at your own risk. Always back up your TA partition (DRM keys) before unlocking if you wish to restore stock functionality later.

Sony does not provide a single "click-to-unlock" software tool like some other manufacturers. Instead, unlocking is a two-step process involving an official Unlock Key delivered via the Sony Developer website.

Before proceeding, confirm your Xperia model is unlockable. Devices from carriers like Verizon, AT&T, or Docomo are usually permanently locked and will reject the unlock command.
