Question DS412+ not booting: serial console shows EFI Internal Shell missing boot devices, but EFI partition on internal storage seems intact

I'm not really pro in software. More in hardware. Could you please lead me to how to restore under Win10. What image I can use for it?
Could it be problem with BIOS crush? Is it possible to restore it without removing?
We usually use HDDRAWCOPY to move files over and from the eDOM. I can build a image form donor if you want. But I would need the serial number and mac addresses. As those get put in the donor with their checksums calculated, and then you can run the image. But the problem you are having doesn't sound like eDOM. Maybe better if you describe it in detail when you power on the unit. As I read you get solid blue, and then flashing again? Does it even beep. The beep is the post boot indicator. When has loaded correctly into memory from the eDOM.
 
He needs a donor DOM for the 412+?
I already provided him with the broken/missing files here in #191/#193.
It would be nice if he could do a little bit of the input/work for us. Maybe you'll have better luck.

It would be nice if you can create image I can use in flash. Here is the board info:
MAC: 0011322508FB
MAC: 0011322508FC
S/N D8LIN05150

Where from to download HDDRAWCOPY? Here are too many sources and most of them spam :(
I cannot be sure if it is BIOS corrupted or flash.
Oscilloscope does not show any activities on 25Q03213. Supply 3.3v and same level on data pins. Dead?

Is the file you need for the 412+?

This is your eDOM file with your info and checksums done for the 412+

I can read it to image. In image I can find serial number. Looks like reading is fine. Why I cannot write image to drive?
Does it have any write protection?
About BIOS chip. As I mentioned above, the chip is powered 3.3v but oscilloscope does not show any activities on data lines. Also no activity on TX of serial port. Is any possibility to check BIOS chip without removing it?
