Hi, i completely missed your message for some reason. I've been really busy in these months. With lvds you mean backight problems? Because for me it works fine, the problem is that when i try to boot a windows install media i keep seeing the circle spin and nothing more. I tried creating an ssd with windows with another pc and if i recall correctly, it BSODs. Thanks and sorry for the late reply

P.S. mind you that i have dosdude's mod with custom gmux fw. Also, which discord group are you talking about?

Hi all! You can try my version of CoreBoot for MacBookPro 8.2 with GMUX physically disabled. I run Windows 10/11 on it, but there are problems with the not very responsive trackpad and hibernation. I recommend turning hibernation off by
Code: 
powercfg -h off
I don't know if it is suitable for versions in which GMUX is disabled by software. And I am not responsible for your possible problems. If you don't have a programmer, it's better not to try. My version does not have an ME region, so you should first flash the version from dosdude1, then boot into Linux, and flash my version via flashrom
Bash: 
sudo flashrom -p internal:boardmismatch=force -c "MX25L6406E/MX25L6408E" --ifd -i bios -w '/path/to/coreboot/coreboot.bin'

P.S. You can rollback to the dosdude1 version by simply replacing the file name in the command with the file from dosdude1

thanks for sharing. i havent dabbled with flashing in linux before. So u recommend that i install dosdudes coreboot first, then install yours afterwards?

any recommendations as to which linux is easiest to do this on?

thx
 
hi everyone, I'm trying to collect coreboot for macbook pro 8.2, but I can't do it, I need any help, please help me, I used the autoport and tried all the Assembly instructions I found, I I'll give any log files,please tell me what kind files
 
Hi @dosdude1. I had my late 2011 mbp fixed by you (amd gpu issue) a few years ago. I just heard of open core legacy patcher. I wondered if you could tell me if that is safe to use on a mbp that has had your "gmux ic bypass" performed on it.

Thanks.

It is indeed! The necessary patch for gMux backlight control with GPU disabled is also included in all OCLP versions.

That pile of MacBook Pros, I remember often seeing a similar sight from my former computer tech job! I was their Apple expert, so I was often assigned to test and reset Mac laptops, especially 2nd-generation MacBook Airs and unibody MacBook Pros, to see if they still had remote MDM enrollment or firmware passwords or any functionality issues before we could either recycle or re-sell them.
 
Hello again @dosdude1.

Question for you or anybody:
I didn't like OCLP - wasn't working well. I put Linux Mint 22.1 on the MBP instead (15", late 2011 MBP, identifier 8,2, Model A1286, with AMD GPU bypass done by you). I'm trying to get an external monitor going.

I've had it work before (before AMD GPU failed and was bypassed) using TB port to hdmi adapter, I think.
Then, I've had it work even after AMD bypass like so; From MBP TB port -> Kanex Model KTU10 -> Startech USB32HDPRO -> HDMI cable > HDMI port on Gigabyte M32Q monitor.
I also had it working while the MBP was on Catalina, using your Catalina Patcher tool, and it was working with just the Startech adapter (no Kanex adapter) in the MBP usb port, but was pretty "slow" and made the fans run high when I'd try to watch a 1080p video on youtube on the M32Q (but I had macs fan control running, so I duno).

I can't get exernal monitor to work. Doesn't seem to sense anything. I duno if I should try and install a display link adapter driver, and if so - which one, and how (on linux mint).

If anyone can provide some direction I'd appreciate it.

Thanks.

Yeah, with AMD GPU disabled, it is not possible to get display out from the DisplayPort. The USB-based DisplayLink adapters will work fine, but are slow as you've seen. You will need the correct drivers to get DisplayLink working under any OS.
 
Even the sturdy mid2012 15" MBP9,1 may fail eventually ...:
Flickering green/red vertical line on the display. PCIe Lane Width at x8.
😥
Edit: I thought, it was a failing GPU, but I mixed everything up with the early2008 MBP4,1 (where normal PCIe Lane Width is x16 and everything below indicates a failure).
With the MBP9,1 PCIe Lane Width x8 is the normal value.

So I swapped the display-assembly with that of a spare MBP9,1 and found out that the display is the culprit.

Sorry for the misleading post ...

Hi @dosdude1 i have an 2011 macbook pro 15 inch with an broken gpu and i suck at soldering. do you know an EASY way to fix it?. and i have used the nvram fix but i want an permanant fix

Edit: im not that old 🙂
 
Dear MacRumors friends,

I've traced the wiring.
The MacBook A1286 - 2011 - (820-2915) starts up, there's the startup chime, but no backlight.
Where have I gone wrong? Could you please help me?
 
Hi!

My 2 MBP 8.2, with Sequoia, start to freeze, but the mouse still moves.

a) I Install Monterey in one, but still freeze, in this one I use a new SSD.
It can freeze about 5 minutes after start, or can take more time.....

b)I take my second 8.2, who have a 1 TB SSD (I use it for one drive backup) and bingo !
The same error happens!
In this case, I remember that I open Firefox...

Any one can gave me a help in here, or its the end?☹️

Thanks

Somewhat related question: I've seen videos of people replacing the dead GPU chip. Was there ever a fixed or improved chip (like with the 2008 MBPs) or were they just replaced with the same type of chip and similar failure is probable in the future?

EDIT: I just watched your MBP 15" 2008 video and in it you say there are no revised chips available for 2011s and I suspect that has not changed.

Yep, never was a revised chip produced for those, and never will be.

Slightly strange question do you think in theory this could be done on a 2010 17 inch Macbook Pro as I just got one for free and it turns out to be missing its GT 330m chip. I was hoping to try out your method as I really don't want the laptop to go to waste? I would really appreciate the help. Thanks
