Sounds good. Make sure you upload the "pre-update" sketch to both the display and controller. After you upload it's important to wait about 7 minutes before updating v5.1 so the Arduino has time to do it's thing, also the Arduino must be mounted to the PCB's for this to work as the eeprom is on the board not Arduino. If you open the IDE serial monitor after uploading the pre-update it'll says start and finish when done. After you do this to both upload the v5.1 sketches and it should prompt you to press OK.
