You'll probably be waiting a very long time. There's no guarantee an exploit for 9.3+ will ever be found. There were a few years between the 4.X and the 5.0+ exploits and it'll likely be even longer for another one.
I'm not sure what to do then. :/ The guide for updating says you can use PBT instead of Pasta, but I don't know much about PBT so I won't be much help with that.
When i launch ds profile with L button my 3DS restart, i think i have to do something with a linker no ? normaly with ds profile my 3DS had to boot on PBT. :/
i read that : mset already installed using Gateway's Installer file.
i think this is the problem because i have nothing to launch gateway, my old linker is blocked by update 4.5 (r4idsn)
