Long story short.... Updated the firmware like the instructions said (from Pioneer and utilizing the micro sd)...... Unit was stuck in a permanent reboot mode with no hard keys working. EVEN WHEN CAR WAS OFF AND KEY WAS OUT. After about an hour I had to undo battery terminal so I would put kill the battery over night and the next day.....
Now when car is turned on, NOTHING HAPPENS to the head unit. No lights, no power etc........
Any way to until brick, or did I just royally **** myself?
