Hello!
When I unsoldered my NAND, I made a serious mistake and ruined the switch's motherboard. I'll have to live with that.

Nevertheless, I went looking and tried to find out where the pin lines run.
The pins are ripped out as above.
Below I looked for the connection points and didn't find any.
The round ones have a connection in the middle. Not the “oval” ones.
Are they not connected at all?
Maybe someone was as successful as me and knows more. ;)

Please make a bigger picture so I can see the whole pins also mark the broken pins in the picture.

All pins marked as NC (Not Connected) can be ignored.
All pins marked as RFU (Reserved for future use) can also be ignored.
The other pins however might cause you trouble.
By the looks of it, you mainly ripped off voltage pads.
You might be lucky that the remaining voltage pads can power the eMMC but that's something you'd have to try.

Yes I have nothing to add 👍

The poor image quality is due to the microscope.
At the end of next week I will have a new (better) one and be able to take a new picture.

If you need someone to fix it I'm also from Germany.

You could use a Sandwich adapter to Modchip, that is a double sided PCB one side is solder to the board and the other is soldered to the chip, on that PBC you repair the missing points.

Thank you very much. It looks better than expected.
However, I opened the marked pins. I can't find any contacts under it.

You can't see all the damaged pins in the picture. In some cases the material is torn all around.
Soon I will get a better microscope and take a new picture.

The pins on the board are damaged. The sandwich adapter would have to supply the pins differently. Are there such parts?

RFU pins are no problem
