vphone-cli

Boot a virtual iPhone (iOS 26) via Apple's Virtualization.framework using PCC research VM infrastructure.

Tested Environments

Host	iPhone	CloudOS
Mac16,12 26.3	17,3_26.1_23B85	26.1-23B85
Mac16,12 26.3	17,3_26.3_23D127	26.1-23B85
Mac16,12 26.3	17,3_26.3_23D127	26.3-23D128

Prerequisites

Disable SIP and AMFI — required for private Virtualization.framework entitlements.

Boot into Recovery (long press power button), open Terminal:

csrutil disable
csrutil allow-research-guests enable

After restarting into macOS:

sudo nvram boot-args="amfi_get_out_of_my_way=1 -v"

Restart once more.

Install dependencies:

make setup_libimobiledevice   # build libimobiledevice toolchain
make setup_venv               # create Python venv
source .venv/bin/activate

Quick Start

make build                    # build + sign vphone-cli
make vm_new                   # create vm/ directory (ROMs, disk, SEP storage)
make fw_prepare               # download IPSWs, extract, merge, generate manifest
make fw_patch                 # patch boot chain (6 components, 41+ modifications)

Restore

You'll need two terminals for the restore process. Keep terminal 1 running while using terminal 2.

# terminal 1
make boot_dfu                 # boot VM in DFU mode (keep running)

# terminal 2
make restore_get_shsh         # fetch SHSH blob
make restore                  # flash firmware via idevicerestore

Ramdisk and CFW

Stop the DFU boot in terminal 1 (Ctrl+C), then boot into DFU again for the ramdisk:

# terminal 1
make boot_dfu                 # keep running

# terminal 2
make ramdisk_build            # build signed SSH ramdisk
make ramdisk_send             # send to device

Once connected, install CFW:

# terminal 2
iproxy 2222 22
make cfw_install

First Boot

Stop the DFU boot in terminal 1 (Ctrl+C), then:

make boot

This gives you a direct console on the VM. When you see bash-4.4#, press Enter and run these commands to initialize the shell environment and generate SSH host keys:

export PATH='/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games:/iosbinpack64/usr/local/sbin:/iosbinpack64/usr/local/bin:/iosbinpack64/usr/sbin:/iosbinpack64/usr/bin:/iosbinpack64/sbin:/iosbinpack64/bin'

mkdir -p /var/dropbear
cp /iosbinpack64/etc/profile /var/profile
cp /iosbinpack64/etc/motd /var/motd

# generate SSH host keys (required for SSH to work)
dropbearkey -t rsa -f /var/dropbear/dropbear_rsa_host_key
dropbearkey -t ecdsa -f /var/dropbear/dropbear_ecdsa_host_key

shutdown -h now

Note: Without the host key generation step, dropbear (SSH server) will accept connections but immediately close them because it has no keys to perform the SSH handshake.

Subsequent Boots

make boot

In a separate terminal, start iproxy tunnels:

iproxy 22222 22222   # SSH
iproxy 5901 5901     # VNC

Connect via:

• SSH: ssh -p 22222 root@127.0.0.1 (password: alpine)
• VNC: vnc://127.0.0.1:5901

FAQ

Before anything else — run git pull to make sure you have the latest version.

Q: I get zsh: killed ./vphone-cli when trying to run it.

AMFI is not disabled. Set the boot-arg and restart:

sudo nvram boot-args="amfi_get_out_of_my_way=1 -v"

Q: I'm stuck on the "Press home to continue" screen.

Connect via VNC (vnc://127.0.0.1:5901) and right-click anywhere on the screen (two-finger click on a Mac trackpad). This simulates the home button press.

Q: SSH connects but immediately closes (Connection closed by 127.0.0.1).

Dropbear host keys were not generated during first boot. Connect via VNC or the make boot console and run:

export PATH='/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games:/iosbinpack64/usr/local/sbin:/iosbinpack64/usr/local/bin:/iosbinpack64/usr/sbin:/iosbinpack64/usr/bin:/iosbinpack64/sbin:/iosbinpack64/bin'
mkdir -p /var/dropbear
dropbearkey -t rsa -f /var/dropbear/dropbear_rsa_host_key
dropbearkey -t ecdsa -f /var/dropbear/dropbear_ecdsa_host_key
killall dropbear
dropbear -R -p 22222

Q: Can I update to a newer iOS version?

Yes. Override fw_prepare with the IPSW URL for the version you want:

export IPHONE_SOURCE=/path/to/some_os.ipsw
export CLOUDOS_SOURCE=/path/to/some_os.ipsw
make fw_prepare
make fw_patch

Our patches are applied via binary analysis, not static offsets, so newer versions should work. If something breaks, ask AI for help.
