Cyclone IV E stuck in POR

My Cyclone IV E (EP4CE6 E144 package) is in a weird state. I have pullup resistors on CONF_DONE, nSTATUS, and nCONFIG. nCE is pulled low. All four of these pins have low voltage readings. (< 20 mV)...

The device can't be expected to work with unconnected exposed pad, the problem has been quite often reported for Cyclone III and Cyclone IV.

Some people managed to drill a hole from the bottom side and connect the exposed pad, don't know if it might be possible with your board.
