I have not seen a hks flash editor or tried to read\write an ecu used by hks editor

If tactrix or oft wont read it then its likely the kjs system changes the seed key access routine in ecu ie its locked. It likely if you wtire a stock rom bach to ecu with hks editor it will unlock scu again.

If you dont have the original hks editor box, then cheapest option is likely to replade ecu then write correct rom to new ecu with tactrix if you have access to one.
Ecu replacement proceedure below
