The configuration has to be readback from the configuration device, not the FPGA.
I would expect EPCQ16 used as configuration device. You want to check if it's connected to the FPGA respectively.
Setup the configuration memory as attached AS flash in programmer and performe examine to readback the configuration as *.jic file.

Thank you for your time and attenuation.The "specific core" (factory default serial flashloader) is selected automatically by the programmer. Just try, or review the documentation.

"Can't reprogram" means what exactly?
You should give us some information what you are trying to achieve. If you are copying a board, may be it uses additional configuration data or even copy protection means.
I have a damaged ZINT-592 board. I want only to reprogram the FPGA and after that repair it.
How is reprogramming the Cyclone IV FPGA going to fix the board? The Cyclone IV is SRAM based and loses it's configuration when powered off. If the FPGA was damaged then just replace the FPGA. Unless they used some sort of "DNA" ID inside the Cyclone IV that prevents configuration of a different FPGA device with the configuration file programmed in the EPCS then it should work after the replacement.
If the EPCS programming device is damaged then there won't be any reliable way to recover the Cyclone IV programming file.
So what is damaged? Maybe you are making the board worse by trying to "reprogram" the Cyclone IV. For all we can tell you might have "bricked" the board.
Why? They are copying the complete EPCS content to the *.jic file.I'm pretty sure that the tools won't allow you to clone an EPCS.
