From: Ataberk Özen <[email protected]> This commit adds support for Xiaomi's Mi Router 4C device.
Specifications: - CPU: MediaTek MT7628AN (580MHz) - Flash: 16MB - RAM: 16MB DDR2 - 2.4 GHz: IEEE 802.11b/g/n with Integrated LNA and PA - Antennas: 4x external single band antennas - WAN: 1x 10/100M - LAN: 2x 10/100M - LEDs: 2x yellow/blue. Programmable (labelled as power on case) - Non-programmable (shows WAN activity) - Button: Reset How to install: 1- Use https://github.com/acecilia/OpenWRTInvasion to gain telnet and ftp access. 2- Push openwrt firmware to /tmp/ using ftp. 3- Connect to router using telnet. (IP: 192.168.31.1 - Username: root - No password) 4- Use command "mtd -r write /tmp/firmware.bin OS1" to flash into the router.. 5- It takes around 2 minutes. After that router will restart itself to OpenWrt.
