How to flash your compatible Xperia XZ3 device
There are 3 variants of Xperia XZ3 that can be flashed with Android Q Beta, H8416, H9436 and H9493.
Note: Please do a factory reset of your device before you flash your device. The user data would have been erased regardless of this step but the device should be clean when installing the software.
Here’s how to flash your device:
- Make sure you have Xperia Companion v2.5 or later installed on your computer. If not, download the latest Xperia Companion from here
- Start Xperia Companion
- Hold down the ALT key (on computer) and click on "Software Repair" on the home screen
- Tick the checkbox “My device cannot be detected or started”, then click “Next”
- Wait for the initialization to complete, then follow the instructions on the screen
Note: You can return to factory settings/Xperia SW at any time by connecting back to Xperia Companion and following the Software repair (without holding ALT key).
Once you have flashed your device with the Q Beta software, all subsequent software releases will be provided via over-the-air updates. See Latest updates & Known issues for more information.
