Preparation

Requires U-Boot flashed to boot_a or boot_b with dtbo erased.

See https://gitlab.com/jenneron/u-boot-sdm-845/-/releases/sdm845-phones-v0.2.0. Use u-boot-odin-m2.img file attached there.

Installation

pmbootstrap install --split, pmbootstrap export and flashing partitions to system and userdata. However, rootfs won't get resized automatically, this can be fixed by using resize2fs from Android.

TODO TODO: We should try to replace the whole UFS lun with 2 pmOS partitions, this should fix all issues with U-Boot flashing and resizing
