Yes, my mistake. The kernel size is right the problem is some minor error in version setting.
factory image from openwrt was set to v6.0. ubnt block to downgrade to lower version below 6.1.
repack factory image from openwrt 19.07 and set version to 6.5, from ssh i can upgrade to openwrt without no problem.
Heres the log:
