I noticed that you are not using: https://github.com/acidanthera/whatevergreen/releases
You could add it to your Kexts folder.

 

Edit: But I agree with @Hervé.

Screen Resolution : 1366 x 768

still no luck to get qeci...

 

i change my config to:

 

-SMBIOS MacBookPro 8.1

-added whatevergreen.kext

-change SNB value to 0x00010000 or 0x00000100

-change device id to 3A1E0000 or 3A1C0000

 

but no QECI, what should I do?

You are not the only person to face this issue on HD3000.

Most people have HD3000 working ootb. But few unlucky ones have the same issue since Mavericks

 

I tried with OC, Clover & Chameleon. No LVDS display without connecting hdmi.

Tried injecting edid as well.

 

No one has solved this issue afaik.

 

PS: ioreg shows entry for Applebacklightdisplay & qeci is working on hdmi

 

Hardware: hd3000 on series 6 chipset (dont need imei patch)

 

Resolution:1366x768 (set in oc/clover/chameleon) yet it chooses 1280x1024

my laptop IHD3000 on series 7, when I use Clover Bootloader is easy to get QECI, just set fake imei to 0X1C3A8086. But to get QECI with OC is really hard.

You can Inject HD 3000 from DSDT patch that's working great.
