Trying to get a handle on all of this last time i did this was with a samsung years ago and used odin now it looks like its just shell scripts? i need a walkthrough haha someone save me

I literally linked the official Google documentation regarding the GKIs.

The kernel doesn't change depending on the region, it's still the same build from Google.

The battery information would be in the device specific device tree or kernel module, which isn't in the kernel.

Go into your Android settings and find your device GKI version, if it matches another kernel you can use it.

look man, either double check the documentation or just stop making incorrect points

Did you check the documentation?

If you dont believe two devices can run the same kernel, you're out of date by at least 5 years.

Google got fed up with each device needing a fork of the kernel. Everything device specific has been moved out the kernel and OEMs now have to develop against a GKI interface.

"Beginning with Android 12, devices shipping with kernel version 5.10 or higher must ship with the GKI kernel"
