7 +Thanks to [[this patch>>https://github.com/openwrt/openwrt/commit/97df795b78dc572ea2ec105ccbf8af27cc4b4d8e]], EA8100 is now supported from openwrt 21.02.

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.

46 +Always use a PC connected to the device via wired ethernet for flashing firmwares.
47 +)))

21 -How to flash if your router currently has stock Linksys firmware:
49 +Follow these instructions:
22 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/]]. 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.
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>>doc:How to Putty.WebHome]] 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. Check you are online by pinging 8.8.8.8 when in SSH.
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.
51 +1. Download ##[[initramfs-factory.img>>https://www.codepowered.com/openwrt/v19.07.7/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-initramfs-factory.img]]## and ##[[squashfs-sysupgrade.bin>>https://www.codepowered.com/openwrt/v19.07.7/bin/targets/ramips/mt7621/openwrt-ramips-mt7621-ea8100-squashfs-sysupgrade.bin||style="background-color: rgb(255, 255, 255);"]]##
52 +1. Access Linksys UI (default [[http:~~/~~/192.168.10.1/>>http://192.168.10.1/]]). Flash **##initramfs-factory.img##**. It will reboot.
53 +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.
54 +1. Flash **##squashfs-sysupgrade.bin##** via LuCi
55 +1. Wait for it to reboot. Now you can configure!
33 33  
57 +For kernel modules, replace the relevant link in your ##/etc/opkg/distfeeds.conf(% class="small" %) (%%)##with this:

35 35  
36 -Sysupgrade from 19.07.x to another 19.07.y will work. You can also upgrade via LuCI. **HOWEVER: **upgrading will wipe entire firmware partitions! Backup your files/config before sysupgrade.
