17 -**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 follow instructions to get the squashfs.bin flashed, then opkg update and opkg install luci.
18 -
19 -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.
20 -
21 -How to flash if your router currently has stock Linksys firmware:
22 -
23 -1. Download the "**openwrt-ramips-mt7621-ea8100-initramfs-kernel-factory.img**" from link above, and flash it via Linksys UI. Wait for it to start to reboot.
24 -1. Configure your computer to have IP in ##192.168.1.2/255.255.255.0##.
25 -1. Check that your router booted Openwrt by visiting [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You are in Openwrt if you see a white screen with message: "The requested URL /cgi-bin/luci/ was not found on this server." (Luci is not installed currently.) Do a reboot if you see Linksys UI instead, then check again when it boots.
26 -1. Download the "**openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin**" from link above, and upload it into ##/tmp## in the router via SFTP. You can use [[winscp>>https://winscp.net/]] if on Windows. [[root@192.168.1.1>>mailto:root@192.168.1.1]] (No password).
27 -1. Ssh into [[root@192.168.1.1>>mailto:root@192.168.1.1]] (no password). Use [[putty>>https://www.putty.org/]] to ssh if you are on Windows.
28 -1. In the ssh shell run: ##sysupgrade /tmp/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin##
29 -1. It automatically reboots after a short while. Log in via SSH again.
30 -1. Run: ##opkg update##
31 -1. Run: ##**opkg install luci**##
32 -1. Access LuCI via [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You can now configure.
33 -
34 -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.
35 -
36 -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.
