Using the Linksys UI will flash openwrt into only one of the 2 partitions. The booting process switches partition every few boots, so if you want to always boot into openwrt then you have to flash openwrt into both partitions. 12 12 13 - If you are on my 18.x below,doing sysupgradeto19.07.x will not work.

Flash the "initramfs-factory.img" via Linksys UI. Wait for it to start to reboot. 19 +1. Configure your computer to have ip in 192.168.1.0/24 subnet but NOT 192.168.1.1. (so, use 192.168.1.2.) Start ping to 192.168.1.1. 20 +1. Cross your fingers that the router boots openwrt. Otherwise keep rebooting until it loads the openwrt partition. (Usually 3 times max.) Wait a few minutes from reboot to let it load. If you get ping response from 192.168.1.1 it means openwrt loaded. 21 +1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router. root@192.168.1.1. No password. 22 +1. Log in as root via SSH into shell. No password. 23 +1. Sysupgrade the uploaded squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots. 24 +1. opkg update 25 +1. **opkg install luci (the flashed images does not contain Luci)** 26 +1. Access LuCI via http:~/~/192.168.1.1/. You can now configure. 18 18 28 +If you are on my 18.x below, sysupgrade will not work. You have to manually mtd write the 19.07 "kernel-initramfs.bin" into the nand and boot/log into it (192.168.1.1), then sysupgrade. 19 19 30 +Sysupgrade will wipe entire firmware partitions!
