The HK8 Pro Max is a popular budget smartwatch known for its large display and extensive fitness tracking features. Like most modern wearables, it requires periodic firmware updates to fix bugs, improve battery life, add new watch faces, and enhance sensor accuracy. Because this device does not run Wear OS or Apple WatchOS, the update process is handled entirely through a companion smartphone app.
: Updates prevent common issues like "boot looping" or system freezes where the device becomes unresponsive. 2. Standard Update Procedure (Portable OTA) The most common and "portable" method for updating the HK8 Pro Max
If a new version exists (e.g., V1.2.3 to V1.3.0), the app will download the .zip or .fw file directly to your phone. This is the portable part—no PC needed.
Keep your phone and watch within 1 meter of each other during the process. Step 2: Connection Open the WearFit Pro app on your Android or iOS device.
: Scroll down and tap on Firmware Upgrade (sometimes labeled as "Find Update" or "System Update").
