I've just seen this type of install at Mercusys MR90X wiki page. What is the benefit of this? Do we get something like "openwrt rescue" type of webpage like in some of those Broadcom routers? It seems interesting. What can we do with this type of install? More fine-grained control?
Such as this thing above? This is good but would be nice if we had like an http server at 192.168.1.1:
Debricking (OpenWrt U-Boot layout)
Place OpenWrt openwrt-mediatek-filogic-mercusys_mr90x-v1-ubi-initramfs-recovery.itb image on the tftp server (IP: 192.168.1.254).
Press “reset” button and power on the router. After ~10 sec release the button.
