I had one UAP Pro in strange state. UAP shines after powering up only white, can do firmware recovery via TFTP, but after update light goes off. It does not automatically reboot after update and it still has a problem when it is turned on. I used PL2303 USB to TTL RS232 converter connected to 4 pin header inside Unifi unit and terminal program Tera Term to see what is wrong. This is what i seen:
