microG relies on the OS to support signature spoofing. Some Huawei device software in some regions does not support it. There's nothing we can do about it.

Huawei AppGallery only offers to install microG on Huawei devices that support it, so if microG does not show in AppGallery for you or does not allow installation, it's likely that downloading it directly from the website won't help you either.

Sorry, there is nothing I can do. It might help to get a different OS version for your device.

And impossible to patch chrome/gmail and other apk files for microG support ?

If I just change region to Malaysia in appgallery then I can install microG from appgallery but with same problem.

Is possible, but not a goal or part of microG.

I think changing region in AppGallery will not change region of the OS. The issue is likely that your OS version "12.0.0.196 (C10E1R1P1)" is unsupported. Huawei uses different OS versions by region. So your OS is not the same version as someone from Europe and thus will have different features.
