Hi Russ, this looks like a case where the Mark Forster lyrics "Flash mich nochmal" also apply. According to the subject a RM500Q firmware has been flashed on a RM510Q which is usually a no-go. AFAIK even different RM500Q models like -GL and -AE have their own firmware files. Please obtain the matching firmware files for your specific RM5100Q model and try flashing again.
