Harman Kardon Software Update Avr 1700 Bco

About 7 years ago, I wrote this post and at the very end I said:

I’ll hold of on the firmware update, if I dont encounter an issue, I’ll leave it alone.

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. Re: Harman Kardan AVR1700 Rcvr BCO update. On Tuesday, March 1. Regarding the file upload method, strangely when I went to Harmon Kardon we bserver. BCO update, is an error caused by a network software update attempt which i.

Well I have finally found an issue! How exciting yes?

I recently purchased a (used) PS4, for the “soul” purpose of playing Bloodborne. But Mike, isn’t that really weird to get a PS4 for one game?

No, and maybe that could be a completely different article if I ever decide to update on a regular basis. I really like the “Soulsborne” games. A good friend of mine introduced me to Dark Souls a while ago, and I have not stopped enjoying this series since.

So yeah, it was worth it.

Here was the issue: HDMI audio would drop off if the receiver felt there wasn’t any incoming input.

However, there was incoming input. During gameplay, I would sit there quietly waiting for a good opportunity to attack. All of a sudden, the speakers would shut off and I would be “deaf” in game. This was creating a serious immersion issue, so I found the thread on avs-forums.com that discussed this issue, and where to get the firmware.

Before I go into the steps required, lets think back on a time when our home consumer electronics were not part of the internet. The great IoT has some pros and cons. The con’s are vendors like Samsung injecting Ads after a new TV software update. Or, when Sony’s smart tv traffic was routing through their servers instead of directly to Netflix or Amazon. Lets not forget the large scale DDoS to DynaDNS due to insecure IoT security cameras.

The pro is, they update as long as the vendor wants to support them.

This great receiver was made 7 whole years ago, when your receiver was not part of the internet. This system has a good ol RS-232 port for maintenance. It even has a maintenance mode button on the back you have to press and de-press 10 times during an update.

It also, and please brace yourselves, required a SPECIFIC USB to RS-232 adapter and Windows 2000 or XP.

The USB to Serial I get, because updating firmware should be carefully controller, and they only have so much they can support from 3rd parties.

The difficult part was getting a hold of XP. 7 years ago that might not have been so hard, but XP is EOL. I had to ask my buddies at Bay Photo (because the photo software industry lags behind as much as this firmware update does) for an ISO or even a VM Image.

So, the first task was creating an XP VM in virtualbox. I had access to an ISO, and thankfully I could perform this task with a 30 day trail and no updates.

Creating an XP VM is pretty trivial. I was almost a walk down memory lane when I say those classic “you’re almost ready!” installation messages:

After the VM was finished with its first boot, and I had the correct adapter ordered from Amazon, I configured the VM to pass the usb device through to the VM.

Then, I installed the drivers for the usb adapter, and ran the check utility

I had to enlist the help of Caralyn while I sat behind the entertainment center. The USB to Serial cable was short, and the instructions cycle between two steps:

  1. Placing the receicver in Maintenance Mode, which is a toggle push button on the back, next to the serial port, and pushing the standby button on the front.
  2. Click next on the software to upload the firmware
  3. After the upload is complete, you have to take the receiver out of standby, pressing the power button on the front again.

We did this about 10 times I think. So, I would wait for the update utility to finish the upload and then I would ask Caralyne to turn the receiver back on and then off when it was done.

I took a few screen shots, and Caralyne took pictures with her phone. I wanted to know what was going on, so I would ask her to take a photo when the state had changed.

Here are the screenshots I remebered to take. Please note how many steps there are, after you select the firmware files, and which serial device to use, its about 8 additional steps. Each one will have you upload new firmware and power-cycle. It is tedious, and there are stories out there of it failing mid way.

I had no issues, everything worked as expected, so I hope others can use the same resources I have listed below in the event this still is a thing.

Here are the screenshots up the update utility:


Did it solve my issue?

YES! I am able to play the PS4 without any audio disruptions.

Have I noticed any other issues?

YES… The volume button on the remote does not work. Other fucntions and buttons on the remote work just fine, like getting into the menu and switching inputs, but the volume is a no go. Really funny, I have to walk over and adjust it manually.

Since this device is EoL, and I got the last firmware update ever, I won’t see a fix for my volume button.

That was my biggest concern with updating firmware unless you know you have a problem. There is no telling what you might introduce :)


  • Startec USB to Serial cable
    • Working cable, I used this as a pass through usb device to the XP vm. The drivers come with a validation tool as well, very handy.
  • AVR 254 - Software Version V0.98.3.1
    • I’ve mirrored the v0.98.3.1 update here, in case it goes away eventually
  • Windows XP SP2
    • You’ll have to find a XP cd image or VM image, I can’t distribute that

If you own a Harman Kardon AVR1700 receiver that has locked up after displaying a BCO Update message, this fix may work for you. It worked for us.

First, the unit was completely frozen. It did not respond to button inputs. Unplugging it had no impact.

We searched the forums (yes we did) and this solution worked for us:

  1. Connect your HK to your home network using an ethernet cable.
  2. Login to your home network (type into your browser) and find the HK. On our Frontier network, it showed up as “new-host”
  3. Type the IP address for the HK in a new browser window or tab
  4. Browse to a small txt file on your computer, then select “Upload”
  5. The system will reject the file as being a non-BCO file, but your unit should “unfreeze.”

No guarantees, but this BCO “fix” worked for us!

Things that did not force a reset:

  • Hold the Surround Sound button for 5+ seconds
  • Press and hold the standby/on button
