Congratulations on recovering from your soft brick state. It's great to hear missteps don't always require hardware replacement.
I am curious what you mean by "modifying the ISO"... there's really nothing that will modify an ISO beyond hex editing in place while ensuring that the file remains exactly the same size (i.e. avoid offsetting data).
If you generated a replacement ISO then I can certainly perceive how that wouldn't work, and could easily cause bricking if it were applied.
