Ok, so I'm sitting with a friends o3ds thats on 10.2E atm. I've been told I CAN downgrade it with BrowserHax, but I can't get the AM:U service running after hours of trying. I was told HomeMenuHax can help this, but I've seen conflicting reports that HomeMenuHax cannot be run on 10.2E. We've also NOT got a nand back-up, so without confirmation about what is and isn't possible I'd rather not play with the SysNand. So, I ask you all. WHat CAN I do? CAN i downgrade from 10.2? WHAT is the best point of attack? IS there a way to get a nand backup before hand first? Just to be safe?
