Have you removed or switched the ROM at any point?

If you upload your ROM dump, I could check it for you.

Usually that happens when rom chip pins have bad soldering joints to pads (in this case motor will not even spin).
Check rom pins under microscope, if you see that soldering is bad then solder it again properly by using Amtech or MG flux paste.

Or it might be that rom got damaged.
