Download or make the OpenWrt initramfs.trx image 2. Connect the PC via LAN to one of the yellow router ports and wait until your PC to get a DHCP lease. 3. Browse to http://192.168.50.1/ 4. If your router is brand new, finish the setup process and log into the Web-UI. 5. Navigate to Administration -> Firmware Upgrade and upload the downloaded OpenWrt image. 6. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device using SCP and install using sysupgrade. $ sysupgrade -n <path-to-sysupgrade.bin> TFTP Method: 1. Download the OpenWrt initramfs image. Copy the image to a TFTP server reachable at 192.168.1.70/24. Rename the image to tufax4200q.bin. 2. Connect the PC with TFTP server to the TUF-AX4200Q. Set a static ip on the ethernet interface of your PC. (IP address: 192.168.1.70, subnet mask: 255.255.255.0) Connect to the serial console, interrupt the autoboot process by pressing '4' when prompted. 3. Download & Boot the OpenWrt initramfs image. $ setenv ipaddr 192.168.1.1 $ setenv serverip 192.168.1.70 $ tftpboot 0x46000000 tufax4200q.bin $ bootm 0x46000000 4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device using SCP and install using sysupgrade. $ sysupgrade -n <path-to-sysupgrade.bin> (based on support for ASUS RT-AX52 by achterin and trx image generation by remittor)
