@MurzikYEET Use the link to the Burner: https://docs.m5stack.com/en/uiflow/m5burner/intro
Then select and download the version for your computer.
Run the app.
Select the M5Stick Plus 2 from the left side bar.
Select the top firmware (official) and click download then burn.
If required, sign in and then configure the settings before waiting for the burn to finish. Then try on UIFlow 2.0 again.
Hope that helps,
