    By looking at https://kb.juniper.net/InfoCenter/index?page=content&id=TSB16495&actp=METADATA I get info that problem is image Key but how to break from this loop so I can add correct image Key (new or old) so I can update image and boot device ?

     

    In fail bootloader device goes also in this sequence but no luck on boot

    This is due to you having the old signature key, and all current software requires the updated signature key.  You'll have to reach out to JTAC for support on that.
