Hi TheKiller57, did you follow Ske1996's 开启HIDPI , 解锁CFG and 修改dvmt至64mb procedure? You need follow step by step by Ske1996.

Myself using Huawei Matebook 13 i5 (2018-2019) (Monterey 12.1), follow exactly the whole procedure by Ske1996 without any problem. From bios 1.28 downgrade to 1.27 solve the issue wont wakeup after sleep mode. Also triple boot , Monterey, Windows 10 and Mx Linux. Brightness working, wifi working, sleep mode working, sound working, battery usage (2 monitor) can last 4 hour.

Awesome Ske1996 skill and procedure, almost full working and stable , thanks Ske1996.

Hello Thank you for your answer, the only step that I did not follow is the bios downgrade, because I have a bin file but I do not know how to flash it ..

After successfully downgrade bios, please unlock again CFG and modified dvmt. And also disable the SIP as well in recovery. Hope it can help you.

[ske1996]

maybe i am not 100% right,but i think this isuess probably related to bios version.

i've heard someone upgrade his bios to 1.30 and caused a not-wake isuess.

was it same in result？

[TheKiller57]

Yes, I tried all the EFIs and it was the only one that allowed me to start and keep iMessages

[ske1996]

……mine need to edit ssn and platform infos before you use. or it wont boot

i wrote that in readme.

follow my readme.

if you did followed my repo and get into os with my original files successfully,see if brightness works.

if it not,try to downgrade your bios is only what i can recommand.

btw,you should ask who send those files,not me. if you are not using my original work. because i cant know what he edited.

[TheKiller57]

I don't know where this EFI comes from, by dint of looking for and testing all the efi lol

Hi TheKiller57,

You must use Ske1996's EFI for Monterey. Follow 100% procedure and files provided by Ske1996.

I had successfully downgrade from my Huawei Matebook 13 (2018-2019) from 1.28 to 1.27 . A Flash BIOS upgrade/downgrade runs the risk of making a board unbootable. Please do it at your own risk.

Download from here

• changed flag to 0 for [Bios_Version_Check] in platform.ini;

• unpacked 1.27 bios file UEFI_FW.bin (from Ske1996) in another folder ("temp"), and renamed to isflash.bin;

• replaced isflash.bin in "Huawei Matebook 13 Bios Downgrade" folder with 1.27 bin from "temp";

• started H2OFFT-Wx64.exe with AC connected, followed advices, rebooted (Once reboot, the downgrade will immediately take effect) .

After successfully downgrade bios, please unlock again CFG and modified dvmt. And also disable the SIP as well in recovery.

Ok succefully downfgrade, i tried to unlock cfg and set dvmt

Thank you for supporting me, btw,disabling SIP is not necessary from macOS 11.0,and i recommend to keep it enabled. For security reason. Of course,that probability of your laptop under attacking is close to zero,lol.
