Now go the endpoint or basement, and again drill a hole which will act as the outlet.

Attach the cable to a coat hanger using electrical tape.

Finally, run the cable to its final destination. This would involve fishing the cable through another wall cavity.

If the pilot hole made by you didn’t work, then you would have to patch it up and bring it to the matching point of the wall by using sand and cement. There are various other options too for filling up of these holes but the material used depends upon the sizes of the holes.
