I used sysupgrade -n
to flash an unifi-ac_mesh from an old LEDE based firmware to an OpenWRT 19.07 based build, but the kernel is not getting upgraded, causing several issues.
uname -a
Linux ap-openwisp-2 4.4.61 #0 Mon May 15 20:43:33 2017 mips GNU/Linux
While looking in the forum, I found this thread: Upgrading fully working Unifi AC Mesh from 18.06.1 to 18.06.2 - kernel stays at 4.9.120 / no WiFi.
Since I do not have physical access to this device, before trying solutions which could harm the device, I would like to ask if anyone can clarify what is happening exactly wit this hardware model?
It's still not clear to me why everything is getting upgraded except the kernel.
PS: found also FS#662 - Sysupgrade messes up Ubiquiti Unifi AP AC Lite.
