Play on Google Pixel

Install magisk

Enable developter options

We need to tap kernel build version and enable developer options.

Enable adb

Turn on USB debugging

Unlock bootloader

WARNING: IF YOU UNLOCK BOOTLOADER, ALL YOUR DATA WILL BE WIPED.

Inside developer options , we need to unlock OEM so that we can unlock bootloader after.

adb reboot bootloader
fastboot flashing unlock

Download the factory images

Install magisk.apk from https://github.com/topjohnwu/Magisk
Go to https://developers.google.com/android to download the relative factory image file. https://link.zhihu.com/?target=https%3A//developers.google.com/android/images
Unzip this image file to get init_boot.img file.
Use adb push ./init_boot.img /storage/emulated/0/Downloads/ to send init_boot.img file to your mobile device.
Use magisk.apk to patch this init_boot.img
Use adb pull /storage/emulated/0/Downloads/{the_patched_init_boot.img} ./ to get patched init_boot.img from the mobile device.

Flash the_patched_init_boot.img file into your mobie device

adb reboot bootloader
fastboot flash init_boot {the_patched_init_boot.img}
fastboot reboot

Done.

Install OTA Images

The key difference between factory image and OTA image is that:

when you use OTA image, you don't need to wipe you mobile or unlock the bootloader .

Please note that: install a OTA may cover the rooted boot_init.img.

So, if you want to install a specific kernel version with root and without wipe your mobile. You should use factory image instead of OTA image
If you don't want to wipe your mobile, just modify flash-all.sh :
# fastboot -w update image-cheetah-td1a.220804.009.a2.zip
fastboot update image-cheetah-td1a.220804.009.a2.zip

Download the OTA that you want in https://developers.google.com/android/ota
Follow the tutorial.

Support 32-Bit Applications

WARNING: If you want to support 32-bit applications, then you must un-install the installed magisk (if existed) and then use forked-magisk to replace magisk, and do the same as previous.

Although Google Pixel 7 / 7 Pro is the first mobile that only support 64 bit apps, the fact is that: all the 32-bit libraries are still available, but Google delete tle supported-abi-list on props.

So, if we modify the props back, then we still can run 32-bit applications perfectly.

There are 2 forked-magisk can do this, just choose one of them:

Enable VoLTE

If your SIM card can use access the Internet, but can't send/receive any messages. Then you should enable VoLTE to make it work.

Steps:

Install Shizuku : https://github.com/RikkaApps/Shizuku
Install Pixel-IMS: https://github.com/kyujin-cho/pixel-volte-patch
Follow the tutorial in Pixel-IMS and you are fine.

Enable 5G

Not recommended in PRC.

Some reviews say the 5G speed depends on which city you are in, and 4G is enough in most cases.
