it seems what device is designed to work only with super master partition, so removing it and create system/vendor as regular partitions also does not work (probably something in vendor and boot rely on super).


as of reasons of my problem it may be some missing metadata about super partition, i am not really understand what is it internally, seems like some kind of volume manager similar to lvm on top of linux-dm, but i am unable to find any details about design of this.

currently device heve following partition table:
