Now for the Jacobi and Gauss-Seidel methods to work the matrix needs to be diagonally dominant. Any help would be appreciated. Its different than making a matrix diagonal. //Because of the downvotes

There is really nothing you can do. If matrix don't satisfy conditions of some method, use other methods that can be applied to this matrix.
Remember, in such bad cases you can use Gauss Elimination to solve SLAE.
