As I mentioned earlier, you cannot update your SmartWatch 3 with LWX48P Android 5.0.1 Lollipop’s OTA package using ADB mainly because of the fact that its stock recovery doesn’t respond to commands over USB connection making it impossible to sideload the manually downloaded OTA. In this guide we’ll be using a different approach for the same purpose that has successfully been tested to work on all Android Wear devices.
Google has officially seeded the Android 5.0.1 Lollipop OS update to Sony SmartWatch 3 wearable via OTA, bumping its build number from KNX01V. This update is being rolled out in stages so it will take some time to hit your device. As usual, we’ve got our hands on the official download link to the OTA package and made it available in this article below.
