The HK website says the following about this problem :
< My AVR 1700 shows an update warning screen 'BCO UPDATE' and freezes. What
can I do? >
'Please perform a reset. 1: Press the front-panel Standby/on switch to place
the unit in the Standby mode (the power Indicator LED will turn amber). 2:
Press and hold the front-panel Surround Mode Button for at least 5 seconds
until the RESET message appears on the front-panel message display. Now the
receiver should function correctly. (Radio presets and other adjustments
will be lost, so these must be re-entered). If this reset does not solve the
problem, please contact the Harman Kardon helpdesk. Please note that a
software update can only be performed with a USB memory stick with files
downloaded from the Harman Kardon web site. It is not possible to update
through direct web connection. We are sorry for any inconvenience you may
have experienced.'
Any use ?

For anyone who has found this thread because their AVR 1700 is stuck in BCO Update mode, I wanted to post a the solution that worked for me this morning:
Connect your AVR 1700 to your home network. For me, this meant temporarily moving my cable modem and wireless router into the living room and connecting the receiver to my router with an ethernet cable.
Using your computer, determine the IP address of the AVR 1700 on your local network. You can do this by logging into your wireless router's web interface, or by using a utility like this one: http://www.nirsoft.n...rk_watcher.html
Type the IP address of your AVR 1700 into a web browser on your computer (it should like this: 192.168.1.xxx, with the last three digits based on your individual network). If done correctly, you will be looking at the Harman Kardon web interface for the receiver.
Click the Choose File button and choose any random file on your computer. I picked a small txt file. Now click the Upload button. Dont' worry about what file you choose. The operation will fail, but you will have jolted the receiver out of update mode.
You're done. BCO Update message should disappear, and life is good again!
I hope this helps!
