So I was playing ACNL, then I put my 3DS in sleep mode after I was done playing. A week later, I come back to play and the screen is all black, though the blue light is still there. I figured it must have somehow froze, so I held the power button to turn it off entirely. Unfortunately, after that, every time I tried to turn the system on, the blue light appears, but the screens remain black, and I can’t actually do anything on the system. I‘m not sure what to do. If it matters at all, it does have CFW installed, but I doubt that’s the issue, as it’s been installed for about a couple years by now with no problems.
Hi! You could try the following: Remove the batteryPress the power button a couple of timesPlug in the power adapter. Try turning it on.Remove the power adapterInsert the battery, plug the adapter inTry to power the console on again. If it works, you’re good, otherwise I’d try the same again also with removing the SD card.
I had this happen to me. I followed the steps above. I also removed the game that was inside after doing these steps, and turned it back on. : )
