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

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

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 @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.

@dosdude1 : Hi, it seems your website (https://doslabelectronics.com) isn't working anymore. Any information from your side on this?

Edit: Sorry, fault on my side....everything is working fine

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.
