Hello! I want upgrade OpenWrt for latest version on my X9S box. How I can do it? I didn't find firmware on OpenWrt official web for Realtek_RTD1295. Also I know about this guide (I cannot use links here, so check it with 'openwrt upgrade' on this forum), but it was published 2 years ago and has 19.07.0 rc-2 version.
I know about this topic, but I wanted upgrade for newest version. Is it newest one in this topic? Also, in this guide using some special build of OpenWrt or it's downloaded from official OpenWrt web?
