    Error: invalid command 'rrgn' indicates that rrgn string was not recognized as one of the command strings.
    If path 1:/reg_41.bin were not accessible, it would print only Error.
    This looks quite weird. Can you upload your update.txt file? And also the boot.bin?

    Believe me or not, this boot.bin doesn't support rrgn command at all (I'm not just guessing, I've disassembled it a little bit).
    So you can't dump regions from this device
    I wonder what's so important could be inside your device that Garmin doesn't want us to dump? Or maybe they're just closing security holes...?

    Yes, most probably you can't do it. Unless some other dumping command is found. But this is not likely to happen.

    ok. thanks. think i better not to tweaks around with this device too much in case anything go wrong.

    BTW, does this mean that i cannot clear non vol in Debugging menu or hard reset the device if anything goes wrong?

    No it doesn't, as boot.bin's rrgn functionality has nothing to do with what you've just listed.
    But clear non vol and hard reset are much weaker than restoring backups with rrgn/xrgn sequence.

    I wonder if older versions of boot.bin for this device would support rrgn ?
