Curious, in what region was your prior experience with this scam? Because I'd heard this was rampant and sophisticated in China – with fraudsters being very advanced in their ability to make "junk inside" devices indistinguishable from authentic broken devices, via any cursory/external analysis. But, until this story, I hadn't heard of it at scale in the US. (And here, as well, it seems the high-quality fakes are coming from China.)
