The EFI posted by @Majkel19 seems fine, although I know that you have the Broadcom card so I would recommend using this one and then adding the SMBIOS using genSMBIOS before you use it.

From what I can see he has the keys put in exactly how I did so I don't think this will fix the brightness control. Can you post your EFI exactly as you're using it.
This solved my brightness keys, thank you! This may be an issue for a separate thread, but if you have the thunderbolt ports or the 60Hz working, I'd love to see how it's done. Those are the only two things holding me back from using this thing as a regular laptop.

Also, I do have my touchscreen working with the Lenovo Active pen 1. Interesting to use such an unconventional product with macOS.

Thank you so much. Your's EFI work flawless on 11.2
i have managed dw1820a iservice work too.
Only it bothers me "recommended repair" warning in battery info. I would not install windows :) i have only macos installed. When i received this yoga, Lenovo vintage showed "246 battery charging cycle" and for battery status "normal" i have updated BIOS and installed macOS
I think battery still is ok.
Any idea for fixing this warning?

Hi,
Battery patch is ok for you?
It has 49% and 8010mAh in settings 159 cycles
I must restart
(I have tried screen rotation, and screen rotated but then was black screen)
After restarting appears warning screen popup shut down, restart ect.
then shut down itself.
Plugged charging and restarted and battery was 1% and battery capacity was 4200mAh 539 cycle
Now full charged and it’s 7701mAh 155 cycle

Has anyone had any success with USB-C devices? My thunderbolt accessories seem to work fine, but a simple USB-C to USB-A adapter isn't recognized.
