While I previously tried different baud rates from 2,000,000 all the way down to 300 I kept reading others who had the same error and lowering the baud rate solved it for them. This morning I thought I would give it another go. I started again at 2,000,000 then went down to 921600, 576000, 460800, etc trying each all the way down. Today 57600 was the magic number and it flashed successfully.
