OpenWRT 19.07.2 Installation on Ubiquiti EdgeRouter X #1 There was an issue with installing OpenWRT 19.07.2 on the Ubiquiti EdgeRouter X : The new distribution build did not come automaticaly with the usual "openwrt-19.07.2-ramips-mt7621-ubnt-erx-initramfs-factory.tar" file that allow installing OpenWRT on top of EdgeOS to replace it by OpenWRT within the router.
For those confused about where to download the tar file....
