Solo finally told her side of the story to Robin Roberts on "Good Morning America" -- explaining that she was struck over the head and concussed by her 6'9", 280-pound nephew.
"It was a very scary night," Solo said.
Hope's nephew and sister were both photographed with bloody wounds following the altercation ... and a 911 caller told officials Hope was "f**king beating people up."
Hope's nephew told police at the time he struck Hope with a broom stick in an effort to get Hope to stop attacking her sister.
The case was eventually dropped due to lack of cooperation from the witnesses.
As for Hope's nephew, he and his mother released a statement saying, "It does a disservice to domestic violence victims to suggest that one's physical size is a determinative of whether one is an abuser."
