EDUP RT2980 OPENWRT version

Hardware Questions and Recommendations

Hi There,

Waiting of delivery of my 3 EDUP RT2980 wifi routers I bought on Aliexpress for 35 euro's a piece. Now is 1 of the 3 routers a openWRT version and 2 of them have "Custom" firmware. Probably a difference is the skin compared to the openWRT version.

But this device is not mentioned in the the "Table of Hardware" on the openWRT site and the hardware seems to be a generic "MT7981BA+MT7976CN+MT7531AE" solution. But i really want to remove the firmware of the routers and extract the config of the openWRT version to make a more official version of openWRT. Also make pictures and log files for the openWRT database.

Can somebody point me best way to extract and reflash the firmware safely on "MT7981BA+MT7976CN+MT7531AE" devices so i can tinker with these units without being afraid to 100% brick them?

If you flash them with an image from a different device, yet using the same hw, you will most certainly soft brick them, at best.

This device is not supported by the official OpenWrt project.

Assuming you are correct about this, it would suggest that the device is possible to support. But as @frollic was saying, if flash firmware for another device onto your RT2980, there is a very high probability that it will brick the unit. Each model has a bespoke firmware image to account for hardware design differences (down to the pin out of each chip).

You can start the process of adding support for your device by following the guide here:
