Hi all,
I recently bought two used Ubiquiti UniFi 6 LR access points and flashed them with the latest OpenWrt build.
The first one seems to work just fine, I haven't found any issues with it. However, the second one immediately acted up. After installing, the LEDs went off and can't be turned on in normal operation. They just briefly turn on at boot. There are also no devices found on the LED config page.
In dmesg, I got the following:
root@OpenWrt:~# dmesg | grep err

It appears that for some reason the LEDs can't be accessed.
I did use the exact same binary to flash both devices and I re-flashed the second AP from the interface, however that changed nothing.
The LEDs also did work in vendor operation (Boot, factory reset, tftp mode), so they aren't broken.
Another weird issue is that I can't access luci for a while when the AP is rebooted, it will just fail the web-UI connection (although I haven't found out yet if that's maybe a browser issue).
Then I've noticed a sticker from some kind of Brazilian telecom-company on the back of the case.
Is there any way to diagnose this issue? Could I maybe just export all the partitions from the working AP and upload them to the strange one or could that break anything?
