Tl;dr - Samsung sounbar stuck in endless power cycle loop after recent loss of power in my home.

A preface: The layout of the electrical in my home is really weird, and it's easy to forget which outlets are on which breaker (like, I'm talking outlets on different floors *not* on the same wall vertically type stuff).

I accidentally tripped the breaker my entertainment unit is on. When I reset it, my Samsung HW-Q90R soundbar stopped playing audio, and was flashing "update update update" on the display.

I've tried everything. Most of the time it won't respond to calls from the remote (changed the batteries), nor the physical buttons on the soundbar. I've tried factory resetting it, tried to push a software update via USB (which could make it worse, actually, as there's a known software update bug that can brick it lol). The smartthings app can't connect with it either.

The strange thing is that the TV is still detecting it, and *sometimes* it responds to the remote and buttons on itself. If will cycle through: On -> D. IN -> update update update -> BYE, over and over again, and every few cycles will appear to behave normally for a moment, let me use the remote, but then goes right back into the power cycle.

I've contacted Samsung support chat, who had me try a few things, and ultimately told me to bring it into a service center. I'm frustrated that I can't figure it out myself.

I think all I really want to know, is, why is something like a soundbar so vulnerable to a brief loss of power? Would this happen every time we had a big storm and had a power outage? This post is more of a vent, than a question really, unless someone has any ideas I haven't thought of yet!

The only other thing I can think of, is maybe the hard reset from power loss triggered an automatic update and that bug I mentioned previously did this and was just a coincidence that occurred.

I normally buy scrub daddy sponges for the kitchen and it's been a while since I bought a different type, but I needed some cheap ones that I could sacrifice to gnarly things like bird poop on the car and so on... I unwrapped the package and the sponges were already damp, and at first got creeped out, but remembered that they have been like that all the times I bought them before... but why??
