Mt7981b Openwrt

[Nathen Paisley]

Theinitial installation of OpenWrt on the Xiaomi AX3000T RD03 (Chinese version) requires installing a vulnerable version of the stock firmware, which allows to proceed with commands to enable SSH access, making the OpenWrt installation possible (refer to the Installation section below).

For the Xiaomi AX3000T RD23 (International version), there is no simple way to install OpenWrt. At the present moment (May 2024), the only way to install OpenWrt on the Xiaomi AX3000T (model RD23) is via UART (which requires opening the device, connecting a UART cable, and following a specific set of steps). This process is recommended only for advanced users and may soft brick your device. The instructions for this process are available in this post: Link to owrt forum.

To downgrade: navigate to the upload firmware page and select the appropriate software version. It will complain about the downgrade. Edit the url and change the 0 at the end to a 1 and press enter. Or change to 2 if there is already 1 (seen on v1.0.64). The downgrade will proceed.

Then reboot your router, it should boot to the OpenWrt initramfs system now. To be sure to use one of OpenWrt's LAN ports (not WAN port), plug the ethernet cable into one of the middle ports, if the cable is not already plugged there (original FW dynamically assigns LAN/WAN).

If you have installed OpenWrt with u-boot mode layout, you can still use above UART recovery procedure, but u-boot will also look for a file called openwrt-mediatek-filogic-xiaomi_mi-router-ax3000t-ubootmod-initramfs-recovery.itb in a tftp server at IP address 192.168.1.254

I was able to compile and install openwrt-23.05.0-rc1-mediatek-filogic for M7981 based router, but I cannot see WLAN nor LAN ports up, they are not working.

ifconfig and wifi did not show any output.

EDIT ;

The device is not GL-iNet but it very similar to it.

when I downloaded GL-iNet firmware from GL website, the WLAN worked but the LAN did not work.

when I downloaded the firmware from Openwrt website, neither WLAN nor LAN worked.

what @Borromini is saying is:

almost every device with wifi chip have a radio calibration data partition

so if you flash some random image with some random partition table, you could erase ART partition and your board will be unusable

It is because ART partition is specific for each device and (mostly) could not be transfered from another (similar) one. This is factory calibration data for your wifi chip
