M5Stick firmware Burn error



  • Hello,

    Today I opened a new M5StickC with the factory firmware on which was working. I then when to burn the latest version of UIFlow firmware 1.6.1, however it keeps rebooting.

    with the following on console. I'm sure it's not a great thing but hope it can be recovered. I can and have returned the factory demo firmware and this works.

    thanks for any help.

  • Yeh, I had this too.
    Try holding down the power button for 5 seconds to stop it booting (make sure it's not plugged into anything!
    I did a power cycle and it stopped but not sure if this was after I erased and resinstalled the firmware in M5Burner



  • Awesome thanks all working

    cheers
