will need to do monolith recovery and possibly cut traces to controller to stop the possible short interfering.
If the "chip" heats up but the card is still detected, albeit with incorrect capacity, doesn't this suggest that the controller is probably OK and that there could be a physical problem with the NAND or its supply voltage?
It could. Or not. The issues include: how much time and money are you going to invest in this one case. Monoliths, microSD are not the easiest package to diagnose, and I don't think it is worth looking at the laptop or card readers supply voltage. How many people on here have the tools and skills to drill, mill, scrape, dissolve or laser away a microSD coating carefully enough to not damage anything, then diagnose, repair?
The quickest, easiest option is to forget it from the start, wire it up, read the NAND and attempt DR that way.
It only takes 1 resistor or cap to lose spec and your Flash circuit could become wonky. Often there is no physical evidence of it even if you could get inside the monolith.
I would be interested to watch a discussion / progression of a diagnose and repair of a microSD circuit though, if it were possible to guide someone through it over the forum.
