Hi!

Since updating to firmware 1.4.0 my R5 camera (with original batterygrip) can´t recognize my original canon batteries LP-E6NH. If i try them without the grip they seems to work fine. Anyone else having this issue?
Is it possible to rollback the firmware one step, or install the 1.4.0 firmware once again?
Thanks in advance!

No such problems with R5, firmware 1.4.0, battery grip (with original firmware 1.0.0), and two LP-E6NH batteries here.

What does the camera say about the batteries exactly?
What does Canon support say about that?

The camera says (translated from swedish) "Battery communication fault" "Is this battery/batteries original with the canon logotype?"
Updated the firmware with batterygrip mounted which could be a bad decision from my side...
Canon support (CPS) only advice is to send the camera for service.

Is it possible to reinstall 1.4.0 firmware (with the batterygrip unmounted)? Is it possible to downgrade firmware?

I have updated the firmware to 1.4.0 without unmounting the battery grip. Have no such problem.

It looks like your battery grip itself is faulty. Can you go to a camera shop and try it with another battery grip?

Or maybe it's worth trying to clean the grip's electrical contacts (both camera-side and battery-side).

Hi all, version 1.5 is out for the R5. However for some reasons on the canonrumors page it is NOT possible to post any comment. Why?
Also, I cannot find anywhere online the update R5 manual (covering also firmware 1.5) downloadable... Please help me...
