problem loading nextion firmware model mismatch

Morris Ford <morrishford@...>

Trying to load nextion firmware on a 2.8 lcd. The load is saying that the model in the firmware and the model of the lcd don't match. Is that a known problem? I have double checked that I have the right firmware and the device is truly a 2.8. The difference between the two is that the firmware model number has R at the end and the device does not. 
Any ideas.
