How to update my XDJ Aero (1.06)

I download latest firmware from official Pioneer website, unzip XDJAERO.UPD to root folder formated at FAT32 flash pen drive, unplug any cables from device, press TRANS + ROLL + ON buttons, see the inscription "UPDATE" on both blank screens, insert flash drive... And nothing happens! I tried to download many firmware files (1.11, 2.00, 3.00) - nothing helps. Two different usb stick, 1 hour waiting... Nothing. Help me, please!
