Yes. The effect of the patch is system dependent.
Got it working! Used this one:

Comment: Boot graphics glitch, 10.12.dp1 (credit denskop)
MatchOS: 10.12.x
Name: IOGraphicsFamily
Find: 0100007525
Replace: 010000eb25

No more glitches, two times screen blink for 1 second!

I'm trying on my Lenovo G50-80 (Haswell)
I have patched AppleHDA using AppleHDAPatcher and it's not working

Code:
bash-3.2# kextstat|grep -y applehda
   97    1 0xffffff7f82508000 0x1d000    0x1d000    com.apple.driver.AppleHDAController (278.56) CFB0D0AE-F09A-3660-8F95-7A02FD5FBF07 <96 95 75 12 7 6 5 4 3 1>
  119    0 0xffffff7f8268a000 0xb4000    0xb4000    com.apple.driver.AppleHDA (278.56) A4EB06C9-A40A-39EF-9C4A-D7F23DB9A2F9 <118 97 96 95 80 75 6 5 4 3 1>
  122    0 0xffffff7f82504000 0x2000     0x2000     com.apple.driver.AppleHDAHardwareConfigDriver (278.56) 06C594F4-3E5D-3BF4-A783-90C741DAA3F0 <4 3>
This is using hot patching method from Probook Repo (I started with by taking my Probook configs and editing on it some SSDTs and config inputs will be edited still in testing)
what works so far
Graphics , USB , Keyboard , Trackpad .
what don't
keyboard shortcuts , audio , battery indicator.

hi dear
use attached kext for AppleHDA & keyboard & trackpad (install With KextWizard)

dont use any keyboard kext (voodoops2 or etc..) remove this kext from /system/library/extentions

for graphics card , you will make hardware bios moding & and increase Dedicate Video Memory Preallocate (DVmt) Value in advanced menu option in bios setting (geting help from bios-mods.com forum)

https://www.bios-mods.com/forum/Forum-Insyde-BIOS-Unlocking-Requests

for usb problem and other problem attach full my efi partition for you , use this work curfully with el capitan & last sierra version (10.12.4)

Thanks I'll try what you said , but why do you say I need BIOS modification for graphics , my graphics works without any modification. It is intel HD 4400 and use clover hot patch to enable it With IGPU SSDT addOns.
I already use applePs2smartTouchPad .
I'll try the apple HDA and post results

Your posts are really off-topic here... This guide is for a Broadwell G50-80, not Haswell (as per post #1).

They share many thing like the same Audio , do you want me to start a new thread for my device ?
