This is the second time I ask this.
Did you use the built in tool with UBB7.7.4 to convert to utf8mb4?
I ran it and it was plug and play.

Prior to the release of the tool I tried two manual attempts and made errors.
It is very easy to miss a step or apply a step in the wrong location.

I don't know if it is to late to run or not now for your case..
