    Default Bootloader locked on LS1B using V1.2

    Just trying to read LS1B PCM and get the "bootloader locked" pop up. PCM checks out okay. -I was in this PCM in the past with no connectivity issues.

    When checking PCM security- it states PCM secured with a custom key. Tried various iterations eg. alt key on, high speed unchecked, 00000, $FFFF, FFFF, 00001 etc..

    Updated to latest v7.5.7 build 282 with no luck.

    Downloaded zip file from $0333 thread with no luck.

    Any foreseeable workarounds?

    Please update to this release: https://forum.efilive.com/showthread...ic-Pre-Release

    Then retry reading the LS1 PCM.
    Then locate and send the trace file from the failed read attempt to me at paul@efilive.com (include a link to this thread).

    More info on trace files: https://support.efilive.com/kb_artic...8552-EOAJ-5912
    See the section headed: Read/Flash Trace Files (V7 only)

    Regards
    Paul
