Hello,
i am new here so hello to all

I have got 8pcs ot 850 evo ssds (MZ7LE512HCH1 on board)...all are cancelled from one company and all have smashed mechanically connectors with screwdriver.
Soo i have changed in some connectors for testing.
Problem is that all must be smashed with other way too.
Inside looks nothing burned/cracked or bended...looks line new. Connected are not detected in bios. ARM S4LN045X01-8030 goes littlebit warm thats normal.

Can anyone help me littlebit where to start to search for problem?

EDIT...
ssd is visible in safe mode as 416MB...but not visible in magician

Check the voltages at the inductors.

...i an able to detect it in safe mode...and bootable update will detect it as unsupported device.
Soo it looks like it is not hw problem.
Now i want to test "hotswap" methot - like it works on evo pro. I have found another working 850 evo 256gb...bootable updater starts, detects 256gb, then swap to broken 1tb...but problem is that updater says that in my ssd is latest firmware so is nothing to update
