I just updated my sons 2DS with the new gateway files and my first time using menuhax. I have it coldbooting into gateway emunand which is great. He is turning 5 soon and i hated the idea of needing the online exploit for him. This offline cold boot method is so much better. I now want my o3ds to be the same. I started by trying to update my 4.5 sysnand to 9.2 using the hold up to boot gateway and then using the super smash bros rom to install 9.2 update. It looked like it worked fine, but now i have a black screen on boot... What can i do?
