UPDATING THE FIRMWARE IS NOT SUPPORTED BY MONOPRICE
Do not update the firmware before completing a few prints. Updating the firmware before using the printer introduces another variable to the troubleshooting session you may have to go through.
Note: If you have trouble updating, please format microSD card or use another microSD card and try again. Try a microSD card that is 4GB or less formatted with FAT. The printer can be picky at which cards it will update from so try a few cards.
