So I bought a Old3DS some time ago, and I sent it to someone to do a Hardmod because it was at 10.6. Now, It came back today but I have absolutely no idea what to do. The person who made the hardmod was also supposed to install the cfw/homebrew and do the downgrade. So I've already copied the CIAs to the SDCard. When I power my 3ds on it opens the Menuhax and it boots homebrew up. There I have the follwoing apps: AuReiNand CHMM2 Decrypts9WIP EmuNAND9 FBI Gateway menuhax_manager v2.2 miniPASTA Region Free Launcher rxTools Super ftBRONY II Turbo I tried opening FBI and tried to install a CIA I downloaded but I had the Invalid Signature error. I also tried opening the rxTools to access emuNAND and install FBI, it says browserhax isn't compatible with my version, which means I can't open the FBI. ::SOLVED:: I had to manually inject FBI into Health and Safety app.
