No se instala con Terminal Emulator, con TE se prueba si esta funcionando.
Esto es lo que necesitas tener instalado:
1.) Root access (su binary required)
2.) Busybox v1.20.4+ w/ run-part support
3.) Need to be on 4.1+ Jellybean or higher
4.) Terminal Emulator app installed
5.) 512mb to 2gb of RAM
6.) Enough space in your /system partition (1.5mb available minimum)
Y esto el como instalarlo (si vas a usar /sdcard como directorio de origen)
1.) Make sure you meet the requirements above
2.) Download the latest version of NOS
3.) Boot into recovery (TWRP or CWM doesn't matter)
4.) Make a nandroid backup
5.) Reboot again
6.) Go into the "/sdcard" folder and read the "READ-ME_sdcard" of the NOS.zip for extremely detailed directions.
7.) Follow said directions to the letter...
