Canon EOS R1 & R5 Mark II Firmware v1.3.0 Arriving Soon

[tomcat]

My R5 Mark II won't upgrade from version 1.2.0 to 1.3.0. Both the camera and EOS Utility say that a downgrade isn't possible. Is anyone else having this problem – or even better, does anyone have a solution? Thanks!

Do you have older firmware files on one of the cards? I had that when going to 1.2.0, there was an old file on the SD card, the new one was on CFe.
