[Guide] Lenovo Z50-70/Z40-70/G50-70/G40-70 using Clover UEFI

[Mikorist]

I managed to get rid of all graphical glitches I had on my z50-70 by changing the AAPL,ig-platform-id to 0c00160a in Mikorist's config. Seems fine to me ATM, I'll test around some more.

       <key>AAPL,ig-platform-id</key>
                <data>DAAWCg==</data>

With that AAPL,ig-platform-id I don't even have QE/CI on G50-70

but with the old one I can up VRAM to 2048 MB

it's fair enough that i can play 4K Video .

I've got QE/CI working just fine with my config, so this is kinda weird.
On both configs I can use 1536MB of VRAM, but your config seems to cause glitches with thumbnails and images in chrome and steam, and screen distortion when mousing over stuff in full screen chrome, steam.
I can kinda remove the image glitches by setting framebuffer-cursor to 00009000 (9MB) but the screen distorsion/scratch effect is still there.
The only thing that made them go away completely was changing the ig-platform-id.
Maybe my config only works on other Z50-70s?
Here's what Hackintool shows with my config. I am kinda clueless when it comes to OC stuff.

I have no idea.. Because the RehabMan guide for the laptop with the HD4400 shows a different configuration.

Hi StStefan, i have a z50-70 laptop, i7-4510u, hd4400, clover and whatevergreen latest versions.
In 10.15.4, if I connect hdmi cable my laptop go to kernel panic during boot, if i power on laptop without hdmi cable works. In 10.15.3 it works even if I connect hdmi cable. Can you help me?

Go to BIOS - put full UEFI mode there from Legacy mode

download my EFI OC 0.5.8

good luck

p.s.
Monitor will work over HDMI when you see the apple logo before logging

All work great with this EFI folder except the TrackPad which is not working at all. Do you have any solution for that?

I've reuploaded EFI.zip again.
Download again. Delete NVRAM - in the beginning.

Give some pictures of laptop

Trackpad is working great again! I’m currently using Mojave as the in-built Wifi is working with it.

I still have graphical glitches with this last EFI
With both Discrete or UMA only in bios

Edit:
using

<key>AAPL,ig-platform-id</key>
<data>DAAWCg==</data>

as @StStefan suggested
solved any issue and allowed me to up VRAM to 2048 too

Hi Mikorist, I have tried your EFI config, no kernel panic during boot but laptop display glitches.
Thank you anyway
