→ Install OpenWrt (generic explanation)

Firmware:

1. currently, wli-tx4-ag300n-squashfs-sysupgrade images don't work. The root filesystem is not recognized which results in a kernel panic.
2. wzr-agl300nh-squashfs-sysupgrade images will boot, but you do not get network access.
3. You can build a patched, bootable image using OpenWrt-ImageBuilder by replacing the partition label “linux” by “firmware” near line 42 in target/linux/ramips/dts/WLI-TX4-AG300N.dts, but results are similar as with the agl300nh image.

Flashing:

1. Send file via TFTP. (IP: 192.168.11.1; only accepts oem roms; 4 sec time window)
2. Set up a TFTP server on you PC and connect a serial cable (with a 3.3V TTL level converter). Hit 2 when prompted during reboot on the console. Specify IP addresses and file name after confirming to flash the firmware.

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

• Upload image file for sysupgrade to LuCI
• Wait for reboot

• Login as root via SSH on 192.168.1.1
• Use the following commands to upgrade.

cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

• If sysupgrade does not support this router, use the following commands.

wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
