10 +The EA8100 contains 2 firmware partitions. 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.

13 -Download the "squashfs-factory.img" if you want to flash via Linksys web UI. After you flashed the img the first time, download the "squashfs-sysupgrade.bin" and run sysupgrade to flash this .bin to both firmware partitions.

17 -Sysupgrade from 19.07.x will not save config! Back up your config and other files in the router before you sysupgrade.
16 +1. Flash the "squashfs-factory.img" via Linksys UI, Wait for it to start to reboot.
17 +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.
18 +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 response from ping 192.168.1.1 it means openwrt loaded.
19 +1. Access LuCI via LAN. (http:~/~/192.168.1.1). Set root password so that SSH server starts. (Do not configure/restart.) This root password is only temporary.
20 +1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router.
21 +1. Log in as root via SSH and the password you set.
22 +1. Sysupgrade the squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
23 +1. Access LuCI via 192.168.1.1 again. You can configure for real now.
18 18  
25 +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  
27 +Sysupgrade will wipe entire firmware partitions! Backup your files/config before sysupgrade.
28 +
29 +Subsequently sysupgrade from 19.07.x should work.
