Thanks, Bernie. PM sent. I've still had no luck, using the copy of MDB1_AQ_237T_S_21B firmware that I downloaded from http://arfore.com/files/MDB1_AQ_237T_S_21B.zip
Two days ago, I was getting the error "Write Flash Error" after the installer erased the flash. Now the installer just hangs after:
I tried using a USB hub to slow down the connection, but it won't connect at all through that way. That's strange, because it did connect 2 days ago, but with the same "Write Flash Error" that I was getting every time.
I also tried lowering the baud rate on the COM port from 9600 to 4800. No change.
The 437_S11 and 542_B11 firmware also would not load. Both of these use the older installer with Step 1 and Step 2. I never make it past Step 1 without fatal errors. Sigh.
This sure is a stubborn brick! But I still have some hope given that others have awoken their sleeping giants.
Any other ideas to try? I see that there are a couple other similar threads, but I don't know what else to try.
(More tired than curious dude at this point)
