I hacked my n3DS XL according to the instruction written on 3ds.guide (Soundhax-> Arm9loaderhax->Luma3ds). The firmware was then updated to 11.4 from 11.2. FBI, Luma3DS and Homebrew Launcher 1.1.1 all started properly. But most of the application within Homebrew Launcher would freeze at red screen during startup (menuhax manager, mGBA, prboom, eshop, blend3r and etc). Super ftpd does work though. I also try to install CHMM2 ver2.8 but it result the same freeze at start. Any ideas? Many thanks in advance!
