Downgrading from Android 12 to 10

[xectis]

I extracted the boot.img from the latest factory Android 10 and made it into .tar. If I install it via Odin, would I then be able to downgrade to the Samsung factory firmware v10? If not, can I downgrade to Android 11?

boot.img is just the kernel, it's not really what's keeping you from downgrading. If you want to use something like Android 10 you're going to have to install custom recovery (root) and flash boot.img, system.img, vendor.img and a few things I may be missing. And even then, this isn't a guarantee that it'll boot.

Once bootloader updates there is no flashing backwards. The only way you can is if the firmware you are flashing to has same bootloader version that you are already on

idk if its even possible

because it'll cause a bootloop
