FPGA should be controllable via JTAG regardless of configuration pin connections (except NCONFIG and nCE which need to be pulled high and low respectively). Is your VCCINT voltage within +-5% of 1.2V? There’s been a couple cases with measured VCCINT ~1.35V (possibly due to bad regulator or soldering) instantly killing FPGA.
