[Poco F5 Pro / Redmi K60 (China)] Miustone:
Looks like our Device use FBE by default. So RO2RW should work just fine... I'll investigate into RO2RW Configs again yet...

Totally willed to! Are You both available to test RO2RW Configs with Me? I'll provide Zips which i will flash with You on My K60 Pro...

They will include safe Configs, no Brick risk ig (Installer is solid). If everything goes right we will get MARS and RW working just fine! Would also be intersting to compare the fstab file from /vendor/etc with You too. It will change after flashing RO2RW (Kinda dirty by doubling entries but it adds EXT4 instead of EROFS). I would like to enhance that later if possible...

Edit: My fstab after patching:

# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
