Hello, I have an SSD that, I suppose, need a new firmware, and I'm trying to fix it using SMI MPTool. But I'm getting this error:

Flash Connectivity Test fail (22)/(08.12)

Information:


(0x22): Flash Connectivity Test fail

======= DLL Error Message =======

I can't get what is wrong here and why this error keep appearing.

What's the fear? (З якого переляку?)

Your type of NAND is not in this tool's database. (Вашого типу флеш немає в базі цього тула.)

Because one day the SSD started to load only in ROM mode, showing as 1GB HDD.

When I click "Auto" in the memory list, it selects one of the items. And, in the error details - "FlashID for each Channel and CE" match the selected FlashID, so I can't understand what is going wrong.

You might need to boot into ROM mode. But what exactly needs to be shorted on your SSD? Post the model and a photo PCB to the forum – maybe someone can help. Google searches often help me...

It is already in ROM mode. It only loads in this mode. Scanning in MPTools shows that it in the ROM mode. I already found needed contacts and connected them - this made no difference, same ROM mode

And the controller type, what is written on the memory and what it gives when reading the NAND ID - can you guess for yourself?

On the controller itself I see following SM2258XT G AB N2UX28.00.
On the memory: VS29F02TEME1

Your NAND really isn't in the database...
Try it, maybe you'll get lucky:

Thank you! I have SM2258XT, and this, as I see, SM2258 - are they compatible?

Also, the question. I downloaded a lot of MP Tool versions for SM2258XT, along with the one that you provided. Yours shows flash as K9AFGD8H0A_DDR300. Some memory lists contains this name, but ID is different from mine. While others contains my ID but with different name. Both options throw errors
