I think what Shadow is saying is that it's the fault of the R4 card being a clone and not the SD card. Still, I don't understand then how other people got their R4 Gold Pros working.
My research suggests that it's a problem with the SD card. I've ordered a new one and will try again. It comes in a few days and I'll report back to you after trying. Hopefully, some of the more experienced R4 users can help us.
I was getting a similar error. The way I attempted to fix it was to turn off R4 updates on the R4 card but then you get the black/white screen error afterwards. So it's not really a fix.
