Its not Sandforce.

Have you looked at it under a thermal camera?

It looks like an OEM version of the 970 Evo Plus:

PM981 ?

No support with anything AFAIK.  Check the voltages at the pmic/nand/sdram,  and then reflow/reball nand. Not promising though based on those I've had in. 

[Alandata Recovery]

Not really sure how to do that...

are there test points for that ?
