Help, My New 3DS Won't Turn On After a Motherboard Disassembly & Technician Check

[Rupcoris]

The console is a New 3DS (not XL)

Some background: After replacing the circle pad in my 3DS the face detection started to fail after a few minutes of use, this problem had happen before but I send it to Nintendo Tech Service and they fixed it. Since then I modded my 3ds with luma so I thought they wouldn't accept a repair request and after a watching few YT videos I thought that maybe the camera ribbon was loose or something and decided to dismount the motherboard al plug everything again, but after that the console wouldn't turn on at all (the blue light wont turn on at all but the orange light would light up when connected).

Realizing I probably messed something up, I sent the console to two different unofficial technicians and none of them could find the cause, one of them said that the board voltages and connections were OK and that the cause was probably an internal processor issue.

Is there anything I can do at this point? I have a NAND and 3ds folder backup.

I have a NAND and 3ds folder backup.

You can decrypt your save data for use on another 3DS, if that's what you're asking?

Yes, sorry for the late reply. What do I need to do?

So do you have another 3DS on which you want to use the save data, or something? Details are useful.

Regardless, you probably want to follow https://gbatemp.net/threads/restore-save-data-from-dead-3ds-2ds.606907/ . Be sure to read at least the first four posts.
