Yongnuo600ex-rt2 info and update question

[MiqsPix]

I know this is a Canon forum but as the above flash is a direct copy of the Canon flash can anyone tell me how to increase the flash power. I have read the manual but cannot find anything easy to understand. Also have tried to download the firmware in case there's an issue but no joy on that either. Below is what I get when trying to update the firmware.

Can you give a bit more information on the problem you are having, tio help someone work out what is causing your problem
EG: Which model of camera do you have?
What mode is the camera set to?
Is the flash on-camera or off-camera?
What settings are displayed on the flash?

As above; what’s the problem, what are you trying to do, what settings, and what do the results look like? (Post an image with exif)

Manuals are not always easy!

As above, some more info who help answer your question.

If you want to control the flash output then a way to do that is use manual mode (M) then press the function button under the +/- sign and use the dial to change the flash power. Page 14 of the user manual, section 5.
