I have a set of recently purchased Redmi AC2100 routers running factory firmware 2.0.370. This firmware does not seem to work with the Method A - web exploit - way to get openwrt onto the device.
Attempting to flash earlier versions of the OEM firmware either by the factory web interface or TFTP recovery does not work. The factory web interface states image verification failure, the TFTP recovery pulls the file from the tftp server but then both LEDs turn off and no further progress occurs. It seems they may have changed the firmware verification method.
Anyone got any advice on this?
