Hi, I have problems with my old 3ds. It was downgraded from 9.2 to 4.5 to be able to use Palantine CFW. Now i wanted to update it, so I installed everything again to use rxtools 3.0 (https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/), but i can't install FBI. Tried both method I have found, via Decrypt9WIP (fragmentation error when dumping H&S), or via rxtools 3.0, and i have no luck with both of them. My Old 3DS is at 4.5. What shall i do? Thanks.
