It sounds like you may be experiencing issues with the firmware update process for your 3D printer. Here are a few troubleshooting steps you can try:

  1. Ensure that the firmware file is in the root directory of the SD card and that the file name matches the naming convention required by your specific printer model.

  2. Check if the firmware file format is compatible with your printer (e.g., .bin, .hex).

  3. Make sure that the SD card is properly formatted (FAT32 is commonly used for 3D printers) and that it is not write-protected.

  4. Double-check the compatibility of the firmware version with your specific printer model.

  5. If possible, try updating the firmware using a different SD card to rule out any issues with the original one.

If you have tried these steps and are still facing issues, it may be helpful to reach out to the manufacturer or consult forums dedicated to your specific printer model for further assistance.
