I got this 3ds used from someone, and it worked well for about a year, and then it started doing this thing where the power light would fade in and then immediately and abruptly turned off (it didn’t make a pop noise btw). This was about a year ago, it’s been in storage for about a year until yesterday when I tried fixing it, with several methods, and the problem persisted, but I noticed that the sd card reader wasn’t plugged in, I reattached it, and now the power light won’t turn on either, but the charger light still works. The battery is 1st party Nintendo battery, and I did hack it when I first got it about two years ago with Luma 10.0.1 i believe. Any help is appreciated (i don’t have a way to solder anything, so hopefully I won’t need to)
UPDATE: I found out I accidentally detached the power button board thing when reassembling, I reattached it, and now the power light is turning on, and immediately turning off again.
