Camera sensor HM2056 (driver problem)

[Jonathan]

If you post a picture of the SCU->Advanced->LPSS & SCC Configuration page from your tablet I can check if it differs from mine (assuming you have the Vi10/Vi10 Pro).
Do you have Android any more, if so do the cameras work with it?
On the Windows side what errors are you getting, if any?

Hi,

I have the same problem. I changed the BIOS now is  J1D_S165C_206_2626 and all the drivers have installed.

The problem is the camera is not working.

Do you have any idea? how to fix it ?.

Yes is the Vi10 Pro, version 221511… Where can i find this? I think in the bios no? I have to say that I changed the bios when I format the first time (following tutorials)… It was the same version but not the same build date, mine was 10/30/2015 and now I dont know exactly (I have to check) but it is an early date.

Something more in case you know… The sound it’s ok, but sometimes when I play something (It doesn’t matter if the tablet is mute) I hear a very low fuzzy sound like white noise (with the earphones too), It is not so annoying… but if it’s possible I want to fix it =)

Thank you very much

same problem

Sorry for the very tardy response.

You can get to the BIOS setup screen by hitting ESC on a keyboard attached to your tablet when starting it up. BE EXTREMELY carefull not to disable any USB settings.
Once at the BIOS setup options if you follow this chain: SCU->Advanced->LPSS & SCC Configuration you get to a screen that lets you enable/disable the I2C controllers.
I’ve tried experimenting on my tablet and the HM2056 is on “LPSS I2C #2 Support”.
If “LPSS I2C #2 Support” is disabled then enable it and save and exit by pressing <F10> followed by <enter> (without the angle brackets, I just use these to indicate keyboard keys).
If “LPSS I2C #2 Support” is enabled then disable it and save and exit as above; boot windows; go back to BIOS and enable “LPSS I2C #2 Support” again; boot Windows back up and see if there’s any change.

Also, you didn’t state whether you have Android on the tablet still.

First of all, thank you for the answer. WTF! Let me explain what just happend because it is like a poltergeist! I tried what you said twice… With the driver already installed and uninstalled abd it didn’t work. But surprisingly after the second try, the touchscreen stop working (phantom touches) and the wifi too xDD… this tablet is amazing… I uninstalled and reinstalled everything and now it is working again. I don’t know what just happend, i did it correctly… I mean I know how a bios works and I didn’t touch any other option, it seems like a bios compatibility problem.

But it seems the idea is correct, I have to figure it out what the other options do maybe in my tablet the camera is another option.

Once again sorry for not responding sooner to this thread, but I wanted to wait until I’d had a chance to experiment on my tablet a bit.

Now, on the issue of BIOS another user has just posted a table of versions here which might help you determine the correct one.

I recently decided to reduce the size of my Android data partition and install Windows from scratch to make use of the extra space, I found that there were many driver problems and that the cameras were particularly problematic. There are lots of interdependencies with other systems, but I got them working in the end.

In case it helps anyone this was my process:

1. Used Double Driver on my working Windows installation to grab the existing drivers.
2. Checked the INF files for all the drivers to check for files that Double Driver had missed and copied them manually (co-installers)
3. Booted to UEFI Shell and removed fs0:\efi\microsoft
4. Booted my Windows 10 32-bit Home installation USB and installed it.
5. Used Double Driver to restore all the drivers except Intel HD graphics.
6. Connected to the Internet and downloaded/installed the graphics drivers here.
7. Moved icnfirmware.sys into c:\windows\system32\drivers.
8. Rebooted and kicked off Window’s Update.
9. For me within about 5 minutes the cameras spring to life, but they certainly didn’t work immediately.

Thank Jonathan. You avoided 20 reinstalls (and my internment in a madhouse). Thank you very much from the heart. 😉

Hi Sergio, glad to help. Believe me, I truly understand the madhouse bit…
