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
