    Hello, are you having the same issue when you trying to burn the UIFlow firmware using the M5Burner? could you try and see if the M5Burner gives you any problems?

  • Hello, i tried the "Factory test" firmware using the M5Burner and EasyLoader_M5Paper_Factory_Test but there is the same message.

    Do you have tried to slow down the upload speed. Had the same with other brands, after reducing the upload speed it works.

    Hello, after contacting M5Stack support the problem is probably the flash chip, M5Stack is replacing my M5Paper.
    I had performed this upload test at slow speed but without improvement. Thanks for your help
