The error message "" (Horizon OS) is a common issue for modded Nintendo Switch users, typically appearing when trying to boot into custom firmware (CFW) like Atmosphère using a bootloader like Hekate .
During the encrypted multi-stage boot process, pkg1 acts as the primary bootloader stage, which decrypts and hands off execution to pkg2 . pkg2 contains the actual operating system kernel, core system services, and secure monitors required to fully launch HOS. pkg2 read failed failed to launch hos
