Connect the SD card reader to your PC or Mac, you should be able to see a disk named “boot”, that’s the EMMC module. If not, please check the connection and make sure the direction is correct.

Open the balenaEtcher, choose the image file you just downloaded, and click flash. Please double check the disk you choose, in case you lost any data.

If the disk disconnected in the middle or the flash failed, please use a different SD card reader.

Once the flashing finished, you are all set. Just put everything back, reboot your printer, and enjoy the 3D printing.
