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.
11 -
12 -How to flash:
13 -
14 -If your router currently has stock Linksys firmware:
15 -
16 -1. Flash the "initramfs-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 ping response from 192.168.1.1 it means openwrt loaded.
19 -1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router. root@192.168.1.1. No password.
20 -1. Log in as root via SSH into shell. No password.
21 -1. Sysupgrade the uploaded squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
22 -1. opkg update
23 -1. opkg install luci
24 -1. Access LuCI via http:~/~/192.168.1.1/. You can now configure.
25 -
26 -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.
27 -
28 -Sysupgrade will wipe entire firmware partitions! Backup your files/config before sysupgrade.
29 -
30 -Subsequently sysupgrade from 19.07.x should work.
