What firmware version for ...
in V6 Problems
Canon 7D Mk 1, Canon 600EX-RT.
Setup is relay mode, but the latest version of the firmware rendered remote power control of the flash inoperable.
Adjusting flash power between 1/128 and 1/1 via the remote transmitter adjusts the corresponding power levels on the camera and flash correctly, but the flash itself does not adjust power. All shots are illuminated exactly the same.
Thanks.

Make sure to only press A & D while turning the V6 on.
BTW, the latest firmware version is V1.1.019.
If the flash is firing ahead of the camera, the problem might be that you are triggering it with your remote shutter release V6 at the same time as you are triggering the camera. Since the camera has shutter lag, it will always be behind. For remote triggering to work, both the remote shutter release V6 (Tx) and the on-camera V6 (Tx) must be in "RELAY" mode.
Does normal triggering (just a V6 on the camera's hot-shoe and the 600EX-RT on a V6 in Rx mode) still work? Make sure that neither of the V6 is in "relay" mode and that none of them has a delay value set. The latest firmware will show any delay value other than "OFF" as "DEL" as a status in the display, but earlier firmware versions did not do that.
Also make sure to select the right flash profile for the 600EX-RT on the V6 in Rx the flash is mounted on.
I'd try that simple scenario first and then proceed to using a remote radio trigger approach (using relay mode) after confirming that the basics are still working.
If V1.1.019 does not work, try any of the older available firmwares. The Updater should allow you to pick a number of the versions that were made available earlier.
Is it you Joe (McNally)?
Glad you solved the issue.
