21 21  How to flash if your router currently has stock Linksys firmware:
22 22  
23 -1. Flash the "**initramfs-factory.img**" via Linksys UI. Wait for it to start to reboot.
24 -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.
25 -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.
26 -1. Scp the "**squashfs-sysupgrade.bin**" into /tmp in the router. root@192.168.1.1. No password.
27 -1. Log in as root via SSH into shell. No password.
28 -1. **Sysupgrade the uploaded squashfs-sysupgrade.bin**. This should flash the openwrt firmware into both firmware partitions. It auto reboots.
29 -1. opkg update
30 -1. **opkg install luci (the flashed images does not contain Luci)**
31 -1. Access LuCI via http:~/~/192.168.1.1/. You can now configure.
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 33  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.
