Your EOS was gold plated, you ruined that. Not the end of the world, replace, or sand if it ever needs it.
You should have been looking for a broken wire at the other EOS switches first, from them, to the fliptronics board, check the other EOS's first.
Next up, check the fliptronics board for a blown fuse. And Tests - Switch Edge - see if flipper button leaf blade switches both register on the DMD. Two on each flipper button. Push in slowly, first lowers register then uppers, when you push the flipper button in. Be sure both flipper button switches work.
