If you can demonstrate actual compensable damage in terms of dollars and cents due to your lending instutition's error in reporting your equity loan in full but it was reported to your credit bureau as a bankruptcy, then you would have a factual and legal basis to file a lawsuit.Ordinarily proving damage to one's financial reputation and the effects of such is a difficult thing to prove needing expert testimony in such an area. I suggest that you consult further with an attorney that practices in the area of consumer law about your matter for a more detailed legal opinion with respect to the facts of your matter.
