33 -1. Access Linksys UI (default [[http:~~/~~/192.168.10.1/>>http://192.168.10.1/]]). Flash **##initramfs-factory.img##**. It will reboot.
34 -1. Wait for Openwrt to boot so that you get to LuCi at [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You might need to restart your PC so that it gets a ##192.168.1.x## address from openwrt. Once you get LuCI, do NOT configure yet! It's not ready.
35 -1. Flash **##squashfs-sysupgrade.bin##** via LuCi
36 -1. Wait for it to reboot. Now you can configure!

44 -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.

46 -Sysupgrade from 19.07.x to another 19.07.y will work. You can also upgrade via LuCI.

49 -Upgrading images will wipe entire firmware partitions! Backup your files/config before sysupgrade. It will reset router ip to 192.168.1.1.

52 ---**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-sysupgrade.bin** flashed, then install LuCI. (See instructions below.)--

54 ---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.--

57 -
58 -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.--
59 -1. --Configure your computer to have IP in ##192.168.1.2/255.255.255.0##.--
60 -1. --Check that your router booted Openwrt by visiting [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. It is in Openwrt if you see a white screen with message: "Index of /." Do a reboot if you see Linksys UI instead, then check again when it boots. --
61 -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>>doc:How to WinSCP.WebHome]] if on Windows. [[root@192.168.1.1>>mailto:root@192.168.1.1]] (No password).--
62 -1. --Ssh into [[root@192.168.1.1>>mailto:root@192.168.1.1]] (no password). Use [[putty>>doc:How to Putty.WebHome]] to ssh if you are on Windows.--
63 -1. --In the ssh shell run: ##sysupgrade /tmp/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin##--
64 -1. --It automatically reboots after a short while. Log in via SSH again. Check you are online by pinging 8.8.8.8 when in SSH.--
65 -1. --Run: ##opkg update##--
66 -1. --Run: ##**opkg install luci**##--
67 -1. --Access LuCI via [[http:~~/~~/192.168.1.1/>>http://192.168.1.1/]]. You can now configure.--
