if the phone has ab system partitioning then it wouldn’t have a separate recovery partition. your phone seems to not even have an xda page for it so there isn’t really anything made for it. building recoveries and roms is more complicated than it seems. idk how it works for recoveries but I know for building roms you need device trees and stuff. your phone probably doesn’t have those already made for it so that means you have to make them yourself somehow. as you can probably tell this is quite above what I know how to do
