@jahaan2311 The "GET mac failed" error when burning UIFlow 2.0 firmware to your PaperS3 (SKU:C139) typically relates to communication issues during the flashing process. Here are the recommended steps to resolve this:
Ensure Correct Download Mode: When connecting the PaperS3 to your Mac, make sure the device enters download mode properly. The screen should remain blank after connecting, indicating it's in programming mode.
Verify M5Burner Setup:
Confirm you have the latest M5Burner version installed for macOS
Select the correct PaperS3 firmware in M5Burner
Double-check the USB port selection matches your connected device
Check USB Connection:
Try using a different USB-C cable (preferably a data cable, not charging-only)
Connect directly to your Mac's USB port instead of using a hub
Avoid using USB-C adapters if possible
Reconfigure Burning Settings:
In M5Burner, click "Configure" before burning
Verify all Wi-Fi settings are correctly entered
Ensure the baud rate is set to the recommended value (typically 115200)
macOS Specific Considerations:
Ensure you have the necessary USB drivers installed
Check System Preferences > Security & Privacy for any blocked developer extensions
Try restarting your Mac and the PaperS3 device before retrying
If the issue persists after these steps, please try burning the factory firmware first using the PaperS3 Factory Firmware and then attempt the UIFlow 2.0 firmware again.
