Apologies if this is in the wrong category.
Last year in October I purchased a Samsung Galaxy Tab S4 from eBay, and up until a couple nights ago it was flawless. However, it suddenly bricked itself. Was working fine, put on charge at night, following morning it wouldn't boot past the Samsung startup logo. No recovery mode, only download mode accessible. I have no idea what caused it, but I'm assuming it's a UFS failure, because I can't write anything to it. Odin won't flash stock firmware at all, and the only thing I've been able to retrieve off it is a PIT layout reading (partition information). The device was stock as a rock also, no Knox tripped or anything.
It's currently registered under my Samsung account (registered it when I got it), but I'm pretty sure the warranty would have run out as it released in late 2018… but Samsung has no way that I know of to check warranty status without the device being on.
What would be the best option going forward? I've done some research and seen people mention Samsung charges a fee to inspect devices if sent in, which I'd rather avoid if it costs more than just replacing the tablet. Paying out of warranty repairs doesn't bother me provided it doesn't cost more than buying another Tab S4… Losing data isn't a problem, I just want to know if it can be repaired as it wasn't a cheap device and I'd hardly expect a less than 3 year old flagship tablet to just randomly die.
