Here is a reference circuit for an SM2258XT:

https://www.hddoracle.com/download/file.php?id=9650

There are three LEDs.

One is a power LED driven directly from the 5V input after passing through the e-fuse.

The other two are driven by the controller. One is an activity LED connected to P10 / GPIO1[0]. The other is connected to P15 / GPIO1[5].

Do you know if that's a power or activity LED - If you have a working donor why no just swap the nand over and get the recovery completed for the client you can work on the why this one does work after.


I dont have the exact donor. That's the problem. The Patient and the donor have different BGA NANDs

It's not a power LED. It must be some kind of activity indicator, as @Lardman has suggested. I think you have a firmware problem, or maybe there is an issue with an encryption key??? If you have another SM2259XT donor, you could try to swap its controller into your first donor and see how it behaves.
