[Xiaomi Redmi 8 Guides, News, & Discussion] sessionid0:
First of all, the download link of all the files required for this "ROM" is taken from the "xda developers forum" posts.

I was constantly experimenting with GSI roms for Redmi 8. I was able to install the Pixel ROM on Redmi 8. I don't think you will have a problem if you follow the steps I shared with you one by one.

I do not take responsibility for the ROM. RESPONSIBILITY IS ENTIRELY YOURS.

Not working

-Face unlock

-Radio

-VoLTE

(You need to make a setting for the camera, notch, LTE Mobile Network and auto-brightness. I told you how to make the settings.)

NOTE: A computer is required to make this ROM setup. It must also be installed in ADB on your computer.

Note: You can install this ROM Google Camera as apk. Unfortunately, there are no features such as Portrait, night mode in the original camera application of the device. However, you can use it if you install it as an apk.

Please download that files:
