I'm using an O3DS with 9.20(U) firmware and a 10.5.0 EMUNAND and want to use Action Replay Codes via QR Codes. However, upon scanning and opening the browser, the system stays on a black screen. I've been told by various sources that I need to 'downgrade' my browser in order to use QR cheat codes.I just don't know how, and I have not been able to find a user friendly guide - or any guide at all for that matter - on how to do so. One person suggested I download 'SpiderBrowser' .cia file with my region number on it, which I did, and install it. The problem is that the file could not be read or installed using FBI, or Big Blue Menu, so I am at a dead end. Anybody know how I can get QR codes running on a 10.5 EMUNAND O3DS? If it helps, I'm also running NTR 3.3.
