Thanks for all the good info, @flyboy013.Usually when you are flashing a device, the device will verify the integrity of the new firmware before proceeding, so I don’t see the risk in the flashing process. I have flashed numerous devices over the years and have never bricked one.
To overcome the concern, I would recommend taking an old device that’s no longer used and become familiar with the process with it.
I’ve been a Mac person for years and I don’t think I’ve had an Ethernet port for awhile now. When needed, I use my USB/Ethernet adapter.
Not sure what other advice I can provide.
