So, I'm trying to jailbreak an iphone through an bootable pen-drive to access his root mode, everything was going fine until, when the program should start, i didnt overcome to the linux man page.
When I use the -exit- command to see what happened, this message comes:

Free initramfsand switch to another root fs:
chroot to NEW_ROOT, delete all in /, move NEW_ROOT to /,
execute NEW_INIT. PID must be 1. NEW_ROOT musts be a mountpoint.

-c DEV Reopen stdio to DEV after switch
-d CAPS Drop capabilities
-n Dry run
BusyBox v1.30.1 (Ubuntu 1:1.30.1-4ubuntu5) multi-call binary.

Usage: run-init [-d CAP,CAP...] [-n] [-c CONSOLE_DEV] NEW_ROOT NEW_INIT [ARGS]

How can I solve this problem?
