@ajb2k3 Thanks for your response.
Yes, i used M5Burner and also tried erase before burning.
I selected "UIFlow2.0 Fire".
But in the meantime i worked with Arduino IDE and tried it again. After flashing with Arduino, Erasing with M5 Burner and Flashing again with M5 Burner its now working. Strange ...
Thank you.
Hi all,
i'm new to the M5Stack universe. I got my Fire 2.7 today and tried to upload the UIFlow2 Firmware for fire.
Flashing is working well (i also get a success message, hash was verified, ....), but the device is dead after flashing.
On the serial monitor i can see that something is corrupted:
Rebooting...

I also tried different version, but without any success. Is there any possibility to work with the Fire and UIFlow2?
Thank you very much!
Best,
