UMC-200 v52 firmware upgrade fails with USB popup error

[peterp]

I'm trying to update my UMC-200 firmware from v47 to v52 to fix the HDMI handshake issue, but the upgrade process fails with a weird foreign language USB popup error.  I've tried many, many times and still get the same popup.  Does anybody know how to eliminate the USB error?

Below is a screen capture of the popup USB error (on right).   The error message is very distinctive, so hopefully somebody will recognize it and know how to fix it.

One quick thought, which USB port on the UMC-200 are you plugged into?
You should be using the white USB B connector.

Thanks for your post.  Yes, I am connected to the correct USB port.   I'm just using a standard USB cable I had lying around (works for everything else), not the cable that came with the UMC-200 (if it did come with one).   Do you know if it uses a standard cable?  I still have all the original packaging from when I bought it from Emotiva, but I'd have to dig through the attic to find it.

I use a standard USB A to USB B cable. I don't remember the UMC-200 coming with one I pulled one off my printer originally.

You problem sounds like #5 of the Dentist Method of updating.

Doc Method:


1: Boot UMC-200.
2: Plug in USB Cable.
3: Open Loader and load the update file.
4: Leave all four files checked and run.
5: Once the 4^th file is finished, UMC-200 will reboot itself.
6: Reset defaults.

Dentist Method:


1: Power off UMC-200 from the back.
2: Unplug USB cable only from PC.
3: Run EMO program on your PC.
4: Find upgrade file and click reprogram and select all files and hit start.
5: A box saying USB comes up with all kind of glibberists.
6: Power on UMC-200 from the back but leave it on amber.
7: Plug USB cable in the PC and power on UMC-200.
8: USB box disappears and it starts loading on the 4th file. Usually there will be all kind of mismatch OSD warnings. Don't worry, it will completely disappear after all the other files were loaded.
9: Then it loads the rest from the top (1,2,3).
10: Make sure all files indicate success.
11: Power down UMC-200 from the back toggle and unplug the USB cable from the unit.
12: Power up the UMC-200 and don't forget the load defaults instructions at the end.


(let's call it "the Jumpstart method").

1) start the updater program on your PC with the UMC-200 Off (or disconnected)
2) set the updater program to update the fourth module.
(BE SURE TO SELECT RE-PROGRAM.)
3) hit START on the updater.
(At this point you will get an error box. DO NOT click OK on the box.)
4) NOW connect and power on the UMC-200.
(The error box should disappear and your load should proceed normally.)
5) You can then go back and install the other three modules.
(They can usually be installed out of order with no problem).

We usually install the fourth module only, then go back and install the first three -
one at a time.

This is what I had saved, if it's not helpful, sorry.

Thanks very much for your reply.  Good to have it confirmed that it is a standard USB cable.  I did try the Doc and "Dentist" method (saw the 2nd posted on another forum when I was searching for a solution), but not the "Jumpstart" method of just starting with only the 4th file first.

I will give that a try tonight.  Thanks for taking the time to share this information.
