A big thanks to Flex for their top notch customer support!  My help desk ticket for my DOU (Dead on Upgrade) Maestro now shows solved.  After a week at Flex my Maestro is on it's way back to me. I should have it tomorrow.  My ticket does not explain what if anything was done to my Maestro and what version of software they loaded it with??  I'll assume it has been fixed but I need to know if I need to revert my 6500 back to SSDR v1.7 or stay at v1.8??  What's the path forward from here?  Some advise would be greatly appreciated.  Thanks again.   (This is a new post because the previous "Issue with Maestro v1.8" has been closed for further comments)

Your Maestro was fixed by manually forcing the PICs on the controller boards out of bootloader mode and doing the software update on them  We are adding logic to the PIC updater code to prevent the PICs from getting locked in bootloader mode.

The Maestro will come with v1.8.3 installed on it.  We recommend that you do not downgrade the Maestro to a lower version since the software to prevent the stuck in bootloader mode has not been added to the SmartSDR for Maestro software and the same problem could occur if you downgrade.

Briefly, the issue that occurred is that the programming of an internal processor (happens to be  PIC from Microchip) did not successfully complete.  We had not seen this before in all of our testing and are still a little baffled as to how it happened.  At any rate, we updated our startup software in the Maestro to check for this problem and, if found, reprogram the processors.  In this case, the processor has the designation "W" in Maestro (there are six processors in Maestro).

In addition, we are now coding/testing a fix that will detect this issue during programming and work to fix it so the problem never occurs in the first place.  We have fixed and sent back all the Maestros we received in our Austin office and will continue to fix the remaining few that arrive here quickly.  A permanent fix with the upgrade should be released soon.  Our office in Germany has the necessary tools to repair any units in the EU (and countries soon to be exiting the EU) so I would expect your local distributors have or will be forwarding your units to our service center in Germany for the same treatment.
