I have an Engenius EAP600 that was running an OpenWRT snapshot from August 2021. Not knowing about the Senao Failsafe issue, I pushed an update to the latest version through LUCI (not keeping settings). After waiting a while, it was still not accessible at 192.168.1.1 (or its old IP address).
There is a chance that we switched from POE to powered during the update.
Connecting with serial and watching it start up, I very quickly get the output below, but then it hangs indefinitely.

I saw from this forum post that the AP may hang at this point if you boot it with the UART connected. However, booting with RX disconnected hangs at the same spot. Booting with USB disconnected, then connecting ~10 seconds later yields only a blank and non-responsive screen.
The ethernet activity light shows blue and blinks with activity when connected to my computer or router. But pings to 192.168.1.1 time out, and no new devices show up in my router's list.
What else can I try to recover this AP? Is it totally gone?
