Upgrade Mikrotik RB2011-UiAS

Installing and Using OpenWrt
1

I have a Mikrotik RB2011-UiAS here. At the time I bought it, I had trouble installing OpenWRT on it because of the bug on the 5 gigabit ethernet ports. I've compiled the source with the patches by hand at home, and have managed to have OpenWRT Breaking Barrier 14.07 running on it.
Now I'm trying to upgrade it, and after following the steps on the OpenWRT website I'm getting an error.

root@gw01:~# sysupgrade -v /tmp/openwrt-18.06.4-ar71xx-mikrotik-nand-large-squashfs-sysupgrade.bin
Sysupgrade is not yet supported on rb-2011uias.
Image check 'platform_check_image' failed.

root@gw01:~# sysupgrade -v /tmp/lede-17.01.0-r3205-59508e3-ar71xx-mikrotik-nand-large-squashfs-sysupgrade.bin
Sysupgrade is not yet supported on rb-2011uias.

Any thoughts or guidance?
Thanks!

Perhaps you could/should install from tftp boot procedure as Sysupgrade is not yet supported on rb-2011uias ?

backup and your configuration if you have customized from luci

I've done as suggested, and now my device won't boot:
