How to Install Bruce Beta Firmware on M5Shark (Based on M5StickC Plus2)

I turned my M5Shark into a mini Flipper Zero — themes, dashboard, and full control.

If you're using a M5StickC Plus2 but customized it like me (I call mine M5Shark), here’s how to flash the Bruce Beta Firmware and unlock its full potential.

What You’ll Need

• Your device: M5Shark (aka M5StickC Plus2)
• USB-C cable
• A PC with Google Chrome or Microsoft Edge
• Access to bruce.computer

Step 1: Go to the Bruce Web Installer

Open your browser and visit:
👉 https://bruce.computer

Scroll down and click Beta Release to access the latest features.

Step 2: Select the Correct Device

Although your device is a M5Shark, on the Bruce flasher page,
you must select: M5StickC Plus2 from the list.

✅ Tip: It might be listed under “M5Stack” – that’s fine. Just choose M5StickC Plus2.

Step 3: Put the M5Shark into Flash Mode

1. Hold down the center button on your M5Shark.
2. While holding, press the reset (RST) button on the side.
3. Release both.

Your device is now in flash mode.

Step 4: Flash the Bruce Firmware

• Click Install on the Bruce site
• Grant USB permissions when prompted
• Wait for the firmware to be installed (under 30 seconds)

Your M5Shark will reboot automatically into the new Bruce interface.

Step 5: Upload a Custom Theme

Bruce lets you switch themes like a Flipper Zero, but first, you need to upload one:

1. Open your browser and visit http://bruce.local (same Wi-Fi)
2. Click Upload Theme
3. Drop your .json or .zip theme file
4. Go to Settings > Themes on your device to activate it

• Ready-made themes are available on the official Bruce server:
• 🌐 Visit http://bruce.local and click Theme Store
