I tried with my 1.6 which has A-B01 and i got this error.
C:\Users\Prabhu>python C:\Users\Prabhu\Desktop\xyclops_flasher.py C:\Users\Prabhu\Desktop\bios.bin COM4
Sync failed... trying 38400 baud
Error: No communication from Xyclops. Check connections or try unplugging your Xbox for 10 seconds.
So, curious for the update.
