my camera got water damage and after two months of cleaning it it worked but kept freezing and showing the message SD ERR...

well this happened to me about a month a go and there is no place in my city and country that sells these parts and i was wondering is there hope for me or is it fried here what Ive done in the past i tore down the camera and used WD-40 and a toothbrush and did everything and accidentally broke the three wires coming from the back case to the camera and the battery is fried and i have a feeling that the usb port is broken so please if anyone could help reach me on b7ri25@gmail.com
