DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. 1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. 2) OpenWrt support for this device has ended in 2022. 19.07.10 was the last official build for 4/32 devices.

The root filesystem is not recognized which results in a kernel panic. wzr-agl300nh-squashfs-sysupgrade images will boot, but you do not get network access. 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: Send file via TFTP. (IP: 192.168.11.1; only accepts oem roms; 4 sec time window) 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. Flash Layout Need Flash Layout for this device! Please check out the article flash.layout. It contains an example and a couple of explanations. OEM easy installation Need OEM install this particular device! Upgrading OpenWrt → generic.sysupgrade 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. LuCI Web Upgrade Process Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL Upload image file for sysupgrade to LuCI Wait for reboot Terminal Upgrade Process 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. cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot Basic configuration → Basic configuration After flashing, proceed with this. Set up your Internet connection, configure wireless, configure USB port, etc. Specific Configuration Interfaces Need config instructions for this device!
