Question Samsung 870 Evo SSD potentially fried ?

That would be a start. If Vout is shorted to ground, then you would need to remove the e-fuse and retest for shorts. If the short then goes away, the e-fuse is the culprit. Otherwise we would need to look further.

ok so I finally ended up cracking the thing open. Images attached, I suspect the eFuse is the black square in the top left of the second image in this link (let me know if im wrong). in the third image, i am showing my multimeter probe next to the board, im wondering if i need a thinner probe to actually take these readings accurately take readings as the pins on the board are much smaller than I had anticipated. Or does it not matter if the probe is touching 2 of the vout pins for instance, when im taking the reading. This is the first time im messing around with something so small and fragile like this so I apologize for the confusion haha

The Vout and Vin pins are internally connected within the IC, so it doesn't matter if you short them with your probe.

ok cool so those probes should be fine. anything in specific i should be careful of so i dont break anything? i will check for continuity between the in and out pins. then also check if vout shorts to ground. what should i probe for "ground" ? also in the image i sent the vin and vout are the top 3 pins or the bottom 3 pins? im not sure if i have the fuse upside down in the image

ground is any screw hole

vout to ground - 17.23m
vin to ground - 17.5m
verified continuity between vin and vout.

so that means nothings wrong with the fuse? is the issue downstream or is there something im missing? if the fuse has power, should i now try to connect the safe mode pins . or try recovery software. what course of action do i take from here
