Unable to update ST70 software

[vshtonov]

I recently acquired an old ST70 pilot control head and had the same issue. The ST70 has software version 1.06 and it would not take a software upgrade from an a67. The product code was D625.

I downloaded the firmware update for ST70 instrument display (not pilot head). It contains two pieces of firmware, one is the bootloader, the other one is the instrument firmware. I upgraded the bootloader first and the product code changed to P625. I then installed the latest pilot control head application software for ST70P and it worked fine. No more resets, no more forgotten settings, works great.
