I am doing upgrade of my RX5808 split exactly as you, but firmware works with bugs:
1. calibration doesn't detect nothing
2. Some freezes of screen are persists.

Already upgraded all what i have, all works great, but i have all pro plus versions.
how do you do calibration?
turn off vtx, turn on calibration, turn on vtx
i prefer doing it in 3-5 meters away from vtx (drone), first without antennas second with specific antennas for specific copter (long range one calibration, short rang other)
you can see calibration difference in this video.
one is calibrated other was not calibrated for that 4s (with osd) setup antennas
the calibrated one worked great even in second hangar thrue several walls.
