UniFi 6 Lite with freifunk
Got an intersting issue recently with an newly bought UniFi 6 Lite device which happens to was setup already with the newly UniFi firmware 6.2.49.
I did some simple downgrade to put an older version on it to get it working with Freifunk. Click more for links.
It seems that the new stock firmware has some security checks in to block writing custom firmwares. As much as I tried I could not get the openwrt running withoug downgrading first.
TFTP recovery to UniFi firmware 5.43.19 for U6-Lite
