RBR50-V2.7.6.6 firmware install issues
I have repeatedly tried installing via both the mobile app and downloading the latest firmware directly from Orbi and ran into issues.
When I try using the mobile app and ask it to check for updates, it soon comes back with "Firmware Check Error." In attempts to download the firmware by way of computer, I receive notice that the disk image (.img file) is corrupt.
I am using the latest versions of the iPhone and Mac operating systems on hardware less than a year old.

Sometimes a file does not download correctly. It cannot hurt to return to the Netgear site and download new copies of the router and satellite firmware:

Unpack the zip files to extract the *.img files for router and satellite.
As FURRYe38 points out, it is highly recommended to update the satellite(s) first and update the router after all satellites are updated.

Do NOT attempt to open the file. Just use the web browser to navigate to where the file is.
Try Safari or Firefox browsers on Mac and load any RBS first using there web pages to load the file then the RBR lastly:
