>[!note] > This is for the new Pebble app, initially released in 2025, which I have taken to calling 'Pebble Core.' These instructions do not apply to the original app. ## Procedure 1. Pair your watch to the app if you haven't done so already. 2. Navigate to the `Settings` tab in the Core app and enable the `Show debug options` setting. ![[Pasted image 20250902114012.png]] 3. Select your device in the `Devices` tab. 4. Select `Firmware Update Debug` ![[Pasted image 20250902114303.png]] 5. Finally, select the `Sideload FW` button and navigate to the `.pbw` file you wish to sideload. ![[Pasted image 20250902114358.png]] *[additional info on Pebble file formats for the curious]([[Pebble File Extensions (.pbw, .pbz, .pbl)]])* #pebble
