If the SPI flash chip is still in working order, then you may not need to
do anything, it may just work.

If not, then you'll need to use DFU mode as documented here:

only-if-necessary-dfu-boot, followed by a regular firmware update.

If the PortaPack is still working then the microcontroller (LPC4320) is
still working.  There's a fair chance that all you've damaged is the USB
ESD protection, which is designed to protect the microcontroller from this
sort of thing.
