Some Anet boards have an outdated or oversized bootloader. If you get a blank LCD after flashing you will need to flash the bootloader on your board. There is no physical way to tell what bootloader you have on your board without pulling it off with a programmer. If your Anet board resets when trying to flash you will need to flash the bootloader. Pinout is on the firmware page for the programming header. We recommend using a USBASP for this OR our specific Uno kit (genuine ones may not work).
If you use our Uno to flash please follow the CR-10 bootloader guide using the Anet pinout and select the Anet V1.0 for the board instead of Sanguino.
You can get a USBASP one here from Amazon below:
