Flashing c930c with c930e firmware?

Hardware Hub
21

Thanks for this.

Hello, same story. I’m not too bothered by the Chinese writing (aesthetically speaking), but is it correct that if recognized as an “e”, the webcam would have more capabilities when it comes to settings?

For instance I think I manage to use the Logitech Camera Settings to get a closeup in in Zoom, but I would like to use the camera with Logi Capture? Any chance with that?

Thanks in advance if anyone knows.

Is there any chance to release a patch for this model directly from Logitech?
If we send some emails with complains, for example.

24

I have contacted Logitech support and they sent me a replacement c930e. (Because I bought a c930e but got a c930c, had to show receipts, etc…)

Pretty amazing from them, I was pleased.

In my country the seller refunded me the cost difference. I’m thinking of sending an email to Logitech, asking them to release a firmware update, based on the s/n of the device.

26

i changed the name everywhere and it seems fine. i’m not sure what features are actually missing. the cam settings app works fine

27

I had feedback from Logi. They claim that the firmware is not programmable, something that I don’t believe. They sent me a url for the latest Camera Settings app, which works fine. Could you share guys the registry keys to change all the Chinese names?

28

I can’t seem to post links directly but Google:
Win 10: **Camera Settings - 2.10.4

MacOS - Software Version: 3.10.12 -

Features seem to work fine. Don’t see a tilt but zoom and move up/down/side works fine.

29

Thinking of buying the c930c because the E is so hard/expensive to get right now. Are the pan/tilt/zoom features easy enough to use with the c930c? Any other reason I shouldn’t buy?

I have received the C930c instead of the C930e after waiting for 6 weeks. I am disappointed because I cannot upgrade the firmware and the Chinese characters are present in Windows when selecting the camera.

Thanks to this topic, I have managed to replace these characters in the registry.

Concerning the camera settings app (LogiDPPApp.exe):
In the Chinese (hc/zh-cn) Logitech support page, download the file with version 1.1.87.0, size is 4.47 MB.
Downloaded file is “LogiCamSettings1.1.87.0.exe”.

You can zoom in/out and “tilt” (in fact it’s just cropping). Software is in computer’s language and the layout is different compared to the “e” version (see C930e Youtube tests) but functionalities are the same.

The only thing missing is the preview.

Overall image quality is good and microphone is stereo.

I bought a c930e on Ebay and received a C930c unfortuantely.

I’m not great with computers so I was wondering if someone could walk me through how to change the name/names in regedit

----EDIT----

Figured it out after puzzling some stuff together using this thread

I searched regedit in the search bar > Edit > Find > I personally had all the check boxes checked including Match whole string only > searched 罗技高清网络摄像机 C930c > right clicked the file that was highlighted with said name and replaced it with Logitech C930c

rinse repeat like 15 times lol

Just got the c930c and have two questions:

  1. Has converting the c930c to c930e been figured out yet, or it likely impossible?

  2. How do you save settings? I am using Logitech Camera Settings and I want to leave the angle on widescreen, but it always defaults to standard. I want to keep it at widescreen in Streamlabs OBS. Since you can’t use the camera in both at once, when I exit Logitech Camera Settings and go into Streamlabs, it is on standard.

Anyone?

I was having a look at this. The updater for C930e doesn’t recognize C930c as a device (as expected) so perhaps there’s a way to force it to flash.

The video.bin is the firmware file (starts with AIT842SF). Can be extracted from MacOS updater, or using Resource Hacker on Windows (RCData > VIDEO).

I started looking into the flash utility, but I don’t know enough about the chips inside to know the protocol for flashing.

35

Perhaps @catsay might be willing to offer advice.

Easy fix…

Get the device ID from Device Manager for the C930e… pay particular attention to the VID and PID ID’s.

Open the fileC:\Program Files\Logitech\LogiCapture\bin\LogiCapture.exe.config.

Then copy the XML device profile for the “HD Pro Webcam C920” from to .

Paste it right under the existing one and changed the name to “HD Pro Webcam C930e” and modify the device guid value with the VID (046D) and PID (0843) from the Device Manager.

Start the app. Now your unsupported Logitech model is supported by Logi Capture

Ran a binwalk on it but didn’t get much from it. Maybe it’s encrypted (though there’s some plain text) – there’s two high entropy sections in the firmware image.

38

I would love to see a video on how to do this correctly, because I couldn’t do it.

39

Yep, this definitely worked. My amendment to this included: HD Pro Webcam C930c and VID_046D&PID_0891
The C930c now comes up in the source drop down list in LogiCapture :slight_smile:
