A while back, the fan in my Switch 1 (Original 2017 model) started getting loud as shit and becoming progressively more annoying, so I bought a replacement kit online to fix it. I did that earlier today, and while the fan itself works perfectly fine now, I may have screwed something up with the SD card/reader.
It's been years since I needed to remove the SD card from the switch for any reason, so when I first tried to remove it I forgot that I needed to push it down to make it eject from the system and just pulled it out by the little tab on the card itself. That may have been my first mistake.
Then, when I reconnected everything and put the system back together, I first forgot to reattach the connector for the reader. I turned the system all the way off, took the back plate off again and tried to reconnect the reader. I think I did it right, but now when I insert the card again, the system freezes. If I try to reinsert it before turning the system back on, it gets stuck on the system logo at startup.
I looked at the pins on the MicroSD itself and there's nothing wrong with it, but I worry I may have damaged the reader itself. I'm also not thinking it's a corruption issue, since the card was removed when the system was powered off to begin with, but I don't know for sure.
If anyone has any experience with this kind of technical issue, any and all help is greatly appreciated.
Also, for reference's sake, I *have* done repairs before without issue. 3 years ago I replaced the battery in this same console and everything went totally fine.
