Just rooting the Nokia 2.2
I'm also looking on how to root my Nokia 2.2, and haven't found anything so far.
By the way the thread title is about "unlocking bootloader", which, as I understand is just one of the first steps of rooting. I'm following the install instructions from Magisk official github page. As I understand, unlooking the bootloader is a simple option in android once you unlock developer mode.
The only obstacle in going through with the Magisk install/rooting instructions, is that I can't find anywhere the "boot.img" file for the Nokia (btw, I'm looking to just root my phone, keepting android and all my user data), for Magisk to patch. Is there actually a specific "boot.img" for the Nokia 2.2, or is it possible to use one from another phone too?
