It did not get bricked, but semi-bricked. You didn't uninstall the Perment 
bootloader before uninstaling PRO Update. Now the permanent bootloaders tries 
to boot into CFW that is no longer present. There is a safety switch (holding a 
proper set of buttons) to boot to OFW in this situation. look for it in the 
wiki section.
