How to flash a router?
Title.
For LibreCMC supported routers, the easiest flashing method is through the update firmware option of the web interface of the router's original firmware.
Thank you! :)
How can a Libre CMC image be chosen then?
Sorry, I have zero knowledge about this
You can download LibreCCMC images from here:
https://librecmc.org/librecmc/downloads/snapshots/latest/
Before downloading, you need to check your hardware revision which appears on the router itself and then download the appropriate version (e.g. v4).
