New 3DS LL Self-Install - Console not booting up

[Antwan]

Hello! This is my first time messaging on the board.

I've recently installed a capture board on my 3DS and did most things right, but now my 3DS won't boot up and I'm not sure why.

I have done the instructions for the install, the only things I messed up on are the few cables that I mistook as latches and the soldering on the ribbon cables leading to the capture board itself. I'm not sure if those are the reasons why my 3DS won't boot up or if it's another reason that I overlooked when installing it.

I was just wondering why it won't boot up and I'm just looking for an answer, as well as if there's any way I can get it repaired.

It could be any of that. Cables not connected right, or bad soldering can make it fail to boot.
Send it in if you want, I'll take a look at it.

Sure! I'll send it to you as soon as I can.
I have a couple of questions: Is there anything I should make a note for? Where should I send my 3DS to?
Sorry for the inconvenience.
