Haha I think you might be right 
Question for me though is, is it just because the cost is significantly lower that it’s opened the floodgates and a higher number of inexperienced users are attempting or is it because of the modchip hardware or software… I mean we saw plenty of examples of bad original SX installs (and 1:1 clone installs) back in the day but the number of deaths in the manner we’ve seen were significantly less and most related to shorted rails at the caps on SoC, ribbon or a failure of the SX modchip itself - typically knocking said caps off and/or removing the modchip resolved the problem - I mean I’m looking at the OP’s soldering joints and nothing looks bad to me, and it did work initially so I’m left looking at the EMMC hardware death or data corruption - which has me thinking on the lack of shift registers on a lot of these newer mod chips… and then thinking is it because the percentage of people affected by this is low but the number of people using them is high 
… I dunno 
hoopefully this topic can provide some clarity.
No, the readings your taking at the indcutors correlate with one of rails on the SoC cap (so don’t worry about that) and afaict your readings here are in the realm of normal for the two rails I was interested in.on a Mariko board.
Next, you need to flip the board over and do the same on the other Max IC I mentioned and after - 3V3PDR, and SYS 
As I meantioned earlier, the resistance to ground measurments I’m asking you to take will confirm whether your EMMC is physically bad/safe or not. So no, keep it plugged into you patient board until aftyer I’ve confirmed your other rail readings
It’s a bad Idea, I do not like hotplugging EMMC’s at all but I especially don’t like doing it with potentially bad IC’s … Wait until after I confirm your measurments, if it’s safe I’ll let you know and you can attempt to dump it’s contents on your unpatched board.
