BH C 3850FS with odd Engine firmware

[habik]

Has anyone come across this version of engine firmware : A72R0Y00050G000300

I am trying to update it with A3GN-0Y0-0050-G-00-2100 and getting C-164 (obviously wrong engine firmware) .

any hints?

If I remember correctly the firmware is specific to which accessories are installed. For example if you have the optional paper tray, the machine will require different firmware than the same machine without the optional tray. =^..^=

I can load any controller firmware the likes of A3GN30G0XXX-899 OR W99. But engine is a problem.

The firmware that you're trying to install is for a non-FS model. You need ​A72R-0Y0-0050-G-00-0800 .neVe-080
