Dell Inspiron 15 7558, trouble booting installer (Unibeast 6.2)

[Twils122]

The guide said to use “Brightness Fix Haswell” for Haswell/Broadwell.

I’m using Bluetooth Hotspot...that may be the issue...?

With the garbled screen, it helps to click sleep and then click to wake it back up.

I'm using Hotspot because I have Intel WiFi and I haven't tried the kext for it yet.

Not for IntelBacklight.kext.
You must read the guides carefully.

Issue with what?

With the garbled screen, it helps to click sleep and then click to wake it back up.

Must enable CSM/legacy boot in BIOS.
And must implement backlight control correctly.

I read the guide and I forgot to tell you that I implemented that patch already and it didn't work, that's why I used the one for Haswell/Broadwell. This is my current DSDT with the first patch "Brightness Fix" implemented.

I was thinking maybe you couldn't connect to the App Store with a Bluetooth Hotspot connection, but as soon as I said that it started working. I changed the Ethernet settings to DHCP with manual address and typed in a random IP address and it said connected and started working. Although I tested it on DHCP later, and it was working, it just says that it has a self-assigned IP.

Turning on "Legacy Option ROM" in the BIOS helped the garbled screen.

"Brightness Fix" is still not working.

Edit: Brightness Fix is working, there is a Brightness slider in System Preferences--->Displays...it just doesn't work by keyboard. Separate issue, which I discovered through further reading.

I'm not sure where to place these lines of code in my DSDT:

into method label _Q10 replace_content
begin
// Brightness Down\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0405)\n
end;
into method label _Q11 replace_content
begin
// Brightness Up\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0406)\n
end;

The output for my brightness controls is "Q1C" and "Q1D"....Q1C being up and Q1D being down.

Those are not code for DSDT.
They are patches for MaciASL.

Ok, thanks. I got it working.

Now I have 2 more problems,

I'm having trouble using the kext USBInjectAll...when it's installed it recognizes my webcam, but my USB ports start acting up.
When it's not installed my webcam is not recognized, but my USB ports work fine.
What should I do?
I attached my debug files with and without the kext installed, my DSDT and a picture of an error message I'm getting repeatedly with the kext installed...the system also doesn't recognize USB flash drives with the kext installed.

I'm also having trouble finding an understandable guide to patching AppleHDA...That doesn't skip steps. I retrieved my codec dump from Linux, but that's about it. What should I do next? Should I just use AppleHDA Patcher?

Yeah, none of the AppleHDA guides out there are complete, and most are not well written.
You have to read more than one, get some experience, and read the Intel HDA spec to truly understand the process.
You can use the HDA patcher if your codec is supported by it.

Ok, thanks.

I have a syntax error in my SSDT. (Brackets) Would you mind fixing it?
