Using AS and .sof

I wish to update an old Cyclone3 using usb-blaster and epcs16. Programmer selects .sof ok but tries to use JTAG. Changing mode to AS results in the .sof file being de-selected and I cannot select it ...

    An .sof can only be used to program directly over JTAG. To put a programming file in a flash/config device, you need a different file format, like .pof or .jic or others.

    Required file format depends on how EPCS connects to programmer. If it has additional AS programming connector (legacy method), you need to convert .sof to .pof file. If it connects through FPGA and JTAG, use .jic.
