The development kit has similar test points (ROM, ISP, HWP). These kits are useless without docs or software tools. That's why I suggested that the seller may have documentation that could help you.

FWIW, SanDisk's Z400S SSD has a JTAG edge connector (J1) plus a single pair of ROM pads. Perhaps the ROM pads are the answer?

I'm wondering whether a general method that could apply to all flash based devices would be to short the NAND or controller R/B* pins (open drain) to ground during power-on. I have recently seen one SSD that does it this way.
