12 +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.

14 -If your router currently has stock Linksys firmware:
14 +**Images do not contain LuCi! (The build process doesn't include it for some reason I have not yet time to figure out.)** You need to have the squashfs.bin flashed, then opkg update and opkg install luci.
15 15  
16 -1. flash the "squashfs-factory.img" via Linksys UI, cross your fingers that it boots openwrt when auto rebooting. Otherwise keep rebooting until it loads openwrt. (Usually 3 times max.)
17 -1. access LuCI via LAN. (It's at 192.168.1.1 so you should set connect your computer and configure your computer with an IP on same subnet eg 192.168.1.2/24). Set root password so that SSH server starts. (do not configure/restart.)
18 -1. Scp the "squashfs-sysupgrade.bin" into /tmp in the router.
19 -1. Log in via SSH.
20 -1. Sysupgrade the squashfs-sysupgrade.bin. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
16 +How to flash if your router currently has stock Linksys firmware:
21 21  
22 -If you are on my 18.x below, sysupgrade will not work. You have to manually mtd write the 19.07 "kernel-initramfs.bin" and boot into it, then sysupgrade. Back up data before mtd write!
18 +1. 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.
23 23  
24 -Subsequently sysupgrade from 19.07.x should work but it will **not **save config! Back up your config and other files in the router before you sysupgrade.
28 +If you are on my 18.x below, sysupgrading to a 19.07 image 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.

26 -Wifi seem to work at 30-40MB/s with a MacBook Pro.
30 +Sysupgrade from 19.07.x to another 19.07.y will work. **HOWEVER: **sysupgrade will wipe entire firmware partitions! Backup your files/config before sysupgrade.
