You haven't mentioned IR.exe. Did you try using that?akroffice wrote: 4. JP1 Remote model: OFA URC 11-4282B00
Both RM and IR need a correct .rdf file to operate correctly. Since Rob doesn't seem to know which rdf that would be, I won't even try to guess.
On download from the remote, IR.exe will look at the signature in the eeprom and use it to select the right .rdf file (if there is one). After you try that, and report the results (maybe upload the resulting .ir file saved from IR.exe into our diagnosis area) we will have a better idea how to help you.
In the normal sequence you may not need IR.exe until after you've built your upgrade in KM or RM. But it is a better starting point now since we're not sure what your JP1 remote really is.
