    Default EFI says RR PCM is Locked

    I keep going just to see what else can go wrong. Latest:

    Never got BT to work but have a connection with USB. I downloaded os and tune from old pcm. Installed RR and tried to upload file to RR PCM and get the following erros:
    Bootloader rejected
    EFI could not unlock PCM.

    Any ideas.

    ANy idea why PCM would be locked as received? I tried writing an update to it yesterday but forgot PCM did not have an OS at time.

    Don't use the "normal" read/reflash options to read/reflash a RR PCM. THey don't work because RR has no flash memory.

    You must only use the RR read/reflash options on the RR control panel.

    The PCM is "locked" only because the locking codes are stored in the flash memory which does not exist. The EFILive<->RR link has full control of the entire RR RAM that is emulating the flash memory so it is sort of irrelevant that the PCM thinks itself is locked.
