I have a new 3ds xl that I bought around New Years, it worked fine and everything until I accidently bricked it while updating and turning off the device on accident. It was on 11.2. I ended up ordering a new motherboard off of eBay and it was on 10.3 same region. So as I replaced it, it turned on just fine but the only problem I have right now that is really ticking me off is that it has a sort of sleep mode issue in which if i close the system it still says on, no matter what I do. It random flickers black and shows the notification light for being in sleep mode and stays stuck sometimes or goes back to normal when I don't touch it. What could be my problem and how can I fix it? (I've used gbatemp for tutorials for years but this is my first post after so long)
