my concern is that you have put a 2003 JDM ROM in a 2004 USDM vehicle. the 2003 ROM may use the LE line on the OBD connector to boot into the reflash mode. the 2004 ROM / ECU / harness doesn't use that wire boot into the reflash mode (it does it over SSM solely), and may use a different ECU pin for the LE line than the JDM (i don't have the JDM schematics, so I can't be sure). if the wiring is somehow different, the code you are running now on your ECU can't "hear" EcuFlash requesting to go into the boot mode anymore.
what about the person that shared the ROM with you? what vehicle are they running it on?
