One could de-solder it, test it, & determine it' value.
So if it screwed up it could be replaced.
PITA for sure, but . . .
BTW, not surprised to hear that it sometimes de-solders itself. There's a reason that on the 17 series hash boards Bitmain puts heatsinks on both sides of the pcb. High power consumption SMDs regularly thermally sink thru their power connections on the underside of the chip.
I have another stick which is fine; so I might actually do this, not sure yet whether to take that risk. I still hope for a response from GekkoScience team. Not sure why not to release this info since it's so trivial to RE.
