OpenWRT - Xiaomi Mi Router 4 OpenWRT Installation

In this video, I will show you how to install OpenWRT on the Xiaomi Mi Router 4. This router is powered by the MediaTek MT7621 SoC with 3 gigabit Ethernet ports and dual band 802.11bgn+ac WiFi. It only comes with Chinese language and intended to be sold in China. In order to install OpenWRT, we can use OpenWRTInvasion to get shell access to the router, and then use SSH or telnet to write the OpenWRT firmware with mtd command. The other way is using a chip programmer which required additional hardwares and knowledge in working with FLASH chip; therefore, I will skip it. The ideal platform to run OpenWRTInvasion is Linux. In this video, I will ubuntu, but other Linux OS will work just fine. You can use Windows with docker, but this will be more complicated.
