Normally the reason for using the serial load CN7 recovery procedure is when the DFU has got corrupted as the serial loader is hard wired into the chip.
You say DFU still seems to be functional and is loading firmware to produce RDY files. It is possible it has got partially corrupted but the first step is to make sure you are loading a good SYS file as that is what has the low level screen drivers.
