My one almost success, but a bit problem : cannot use Google Pay and Netflix.
I also used tools payload dumper to extract .img files and Magisk to root it to change /vendor/factory/COUNTRY if you're interesting and already experience with them.
Detail I still need to investigate to solve my current problems, so not announce here in case you also get the trouble
Ok, I extract .img and root it using root boot.img and change Fingerprint already.
Have you relock after that?
