How to update Xiaomi Router 3 PRO (R3P) to the new version

Hey guys.

I've been using OpenWrt version 19.07.6 r11278-8055e38794 for a long time and I would like to update to the new version but I can't find the correct procedure to do.

Can anyone help?

Since your device is an mt7621 subtarget, you'll need to upgrade without keeping your current configs, and re-configure from scratch.

Backup your old configs and use that as a guide.

How do I clear settings using the sysupgrade command?
