I'm on version 7.1.0-10U according to my System Settings on an O3DS. I have a stable internet connection on my console. Every time I scan the QR code, it does the black screen, I install, then it asks me to run the exploit. I select A: Yes and it runs 20%, then 40%, then launches my web browser. The web browser shows a loading bar that fills up and then the 3DS chimes, and after the chime it is completely locked up. I have to power it down completely in order to use my device.
