Unable to flash OpenNept4ne on the factory EMMC module

[Charless96]

Hello, im trying to flash the new firmware on the factory emmc module but when i try to do it in balenaetcher or rufus following wiki instructions it shows an error: not enough space on device. Since the wiki did not say anything about needing a bigger emmc module i figure i wouldn't need one so i just ordered the emmc usb reader.
