-iOS 15.0-16.3 work in progress, semi-tethered checkm8 jailbreak
-</p>
+Jailbreak for A8 through A11, T2 devices, on iOS/iPadOS/tvOS 15.0, bridgeOS 5.0 and higher.
 
-# BEFORE YOU USE
 
-This is mainly for ROOTLESS, and is NOT READY. It was made public so you can contribute and explore the code. This is not the final product.
 
-This version of palera1n supports booting fakefs setups with the `-f` option. No arguments required.
 
-This version of palera1n is able to create fakefs with the `-c` option, however as of right now if the `/jbin/loader.app`
-doesn't exist (which is true for any fakefs created with this version of palera1n), the loader that appears would be rootless.
+| ![Screenshot of macOS Terminal.app](assets/image-1.png)	| 
+|:--:												| 
+| A screenshot of palera1n being used in a Terminal | 
 
-Loader app does appear on rootless, and you can use the SSH server listening at 127.0.0.1:44 (IPv4) or ::1:44 (IPv6).
+## Device Support
 
-If the device is previously jailbroken, the jailbreak environment is automatically prepared. 
-You can use the `-s` option to skip this behaviour.
+<!--- Mobile --->
 
-Usbmuxd is only required for starting in normal mode, it is not required when started from recovery or DFU mode. (Usbmuxd is preinstalled with macOS)

-# Patreons
 
-Thank you so much to our Patreons that make the future development possible! You may sub [here](https://patreon.com/palera1n), if you'd like to. If you subscribe, please message [Nebula](https://twitter.com/itsnebulalol) in any way preferred to have you put here.
+## Computer Requirements
+1. **USB-A** cables are recommended to use, USB-C to may have issues with palera1n and getting into DFU mode.
+> Due to USB-C cables having different accessory IDs, your device may not be able to be recognized when using USB-C due to not being able to assert to its USB voltage pin.

+2. **Linux or macOS computer**
+> AMD CPUs (not AMD Mobile) have an issue where it causes them to have a very low success rate with checkm8 exploit. It is not recommended that you use them with palera1n.
 
-# What does this do?
+> USB-C port on Apple Silicon Macs *may* require manual unplugging and replugging of the lightning cable after checkm8 exploit. This problem may be solved by connecting via USB hub, though extensions can vary.
 
-It boots the device with patches for the jailbreak. 
+## Usage 
+```
+Usage: palera1n [-DEhpvVdsSLRnPI] [-e boot arguments] [-k Pongo image] [-o overlay file] [-r ramdisk file] [-K KPF file] [-i checkra1n file]
 
-**WARNING**: I am NOT responsible for any data loss. The user of this program accepts responsibility should something happen to their device. While nothing should happen, jailbreaking has risks in itself. If your device is stuck in recovery, please run `futurerestore --exit-recovery`, or use `irecovery -n`.

+- iPhone/iPad/iPod/Apple TV
+- iOS Version
+- Passcode enabled?
+- Verbose from palera1n (specifying `-Vv` within palera1n)
+- Panic logs, if panicked then send latest `panic-full` log from your device.

+.Op Fl S Ar password
+.Ar bootstrap-file
+.Xc
+Deploy a bootstrap from a zstd compressed tarball. With no additional options specified,

+Do not prompt for the password and do not set the mobile password.
+.It Fl S Ar password
+Do not prompt and set the mobile password to the password specified.

+even if the device is not currently in safe mode. In this case, a userspace reboot
+is still triggered.
+.Pp
+.Em NOTE:
+Many tweak injection packages also provide their own safe mode, p1ctl does not
+recognize and cannot control those safe modes.
+.It Xo Ar help Op Ar subcommand

+.El
+.It Xo Ar reboot-userspace
+.Xc
+Unmount /Developer if mounted and then reboot the userspace.
+This command exists because the /Developer mount will be broken
+after a plain userspace reboot, which breaks debugging in Xcode.
+.Nm palera1n
+also hooks the
+.Xr reboot3 3
+call so that rebooting userspace using
+.Xr launchctl 1
+does not break the /Developer mount.
+.It Xo Ar reload
+.Xc
+Causes the

+launchd hook to re-probe the environment and update its internal state.
+This will affect the internal environmental variables passed onto new processes,
+and is typically used after bootstrapping or reverting installs.
+.It Xo Ar revert-install
+.Xc
+Remove jailbreak files from the device. This command is not supported on rootful with fakefs. On rootful with realfs, the device will reboot after issuing this command.
+.Pp
+To remove jailbreak files on rootful with fakefs, use

+.Sh DESCRIPTION
+.Nm
+jailbreaks an arm64 (arm64e excluded) iOS/iPadOS/tvOS 15-26, bridgeOS 5-10 device,
+utilizing the
+.Em checkm8
+bootROM exploit.
+.Pp
+.Nm
+provides rootful and rootless jailbreak modes.
+On iOS/iPadOS 15.0 and later and on tvOS 18.2 or later,
+.Nm
+is able to jailbreak the device in fakefs-rootful mode, where /
+is writable, as well as rootless mode, where / cannot be written to.
+On tvOS and bridgeOS,
+only rootful is supported. On versions where fakefs-rootful is not
+applicable, palera1n modifies the actual root filesystem instead
+of making a fakefs.
+.Pp
+Due to the nature of the
+.Em checkm8
+exploit,
+.Nm
+is semi-tethered. That is, you must run the
+.Nm
+tool after the device reboot in order to enter the jailbroken state.
+However, it is not required for the device to boot.
+.Pp
+On A11 devices, that is, iPhone 8, iPhone 8 Plus and iPhone X, the passcode cannot
+be used.
+.Pp
+On iOS 15, the passcode must be off while jailbroken.
+.Pp
+On iOS 16, the passcode must be off since restore, and
+.Sy Reset All Contents and Settings
+from settings app counts as a restore.
+A backup may be used in this case.
+.Pp
+In the remainder of this document, the term "iOS" and "iPadOS" will be used interchangably
+as the difference is negligible as far as the jailbreak is concerened.

+.Sh OPTIONS
+.Bl -tag -width -indent
+.It Fl -version
+Prints the program version and exit.
+.It Fl -force-revert
+Remove the jailbreak while keeping user data. Some jailbreak files may remain
+after running this command. Additionally, jailbreak apps may remain on the
+home screen on for a while even when the files are deleted as the icon cache
+still has their icons. When used with
+.Fl f , -fakefs ,
+this will actually boot the device in rootless mode then delete the jailbreak
+files. As a result, using the loader app to install the jailbreak environment
+is not supported when this option is used together with
+.Fl f , -fakefs
+\[char46]
+.It Fl B , -setup-fakefs-partial
+Like
+.Fl c , -setup-fakefs
+but the size of the created fakefs is smaller at the expense of having unwritable
+parts in rarely-written paths. When jailbreaking 16 GB devices, this option must be used
+when setting up fakefs for rootful, as they do not have enough storage for full fakefs.
+This flag is supported on iOS/iPadOS 15.0 or later and tvOS 18.2 or later, as they
+require fakefs for rootful.
+.It Fl c , -setup-fakefs
+When used with
+.Fl f , -fakefs ,
+creates the new APFS volume required for rootful. Will fail if one already exists.
+This flag is supported on iOS/iPadOS 15.0 or later and tvOS 18.2 or later, as they
+require fakefs for rootful.
+.It Fl C , -clean-fakefs
+This option is not currently supported and is a no-operation in this version of
+.Nm
+\[char46]
+.It Fl d , -demote
+Set the effective production fuse to 0, so as to enable hardware debugging features.
+.It Fl D , -dfuhelper
+Execute the DFU helper to guide the user into putting the device into DFU mode
+then exit.
+.It Fl e , -boot-args Ar boot arguments
+Specify custom XNU kernel command line. Additionally, the
+.Em wdt=-1
+argument is used during fakefs setup.
+.It Fl E , -enter-recovery
+Exit after entering recovery mode.
+.It Fl f , -fakefs
+Proceed in rootful mode. Despite its name, this applies to both full, partial fakefs, as well as realfs, and it still applies even when trying to force revert.
+.It Fl h , -help
+Prints help text.
+.It Fl i , -checkra1n-file Ar checkra1n file
+Specify the path to a custom checkra1n file.
+On Apple platforms this will disable the built-in checkra1n helper.
+A custom one may still be specified with
+.Fl -override-libcheckra1nhelper
+\[char46]
+.It Fl k , -override-pongo Ar pongo file
+Override PongoOS image. The raw image, named
+.Em Pongo.bin
+when built, should be used. PongoOS 2.6.0 or later is required.
+.It Fl K , -override-kpf Ar KPF file
+Override the kernel patchfinder PongoOS module. The module is required to support setting
+root filesystem in paleinfo with
+.Em rootfs
+command. If in doubt, use
+.Sy https://github.com/palera1n/PongoOS
+iOS15 branch or your own fork of it.
+.It Fl l , -rootless
+Proceed in rootless mode. This option is only supported on iOS/iPadOS.
+.It Fl n , -exit-recovery
+Exit recovery mode and exit.
+.It Fl o , -override-overlay Ar overlay file
+Specify the path to a custom overlay file, which is then mounted onto /cores/binpack
+during boot, if the default ramdisk is used. The default ramdisk expects the overlay
+to contain a folder named
+.Em Applications
+at the root of it, as well as a dmg named
+.Em loader.dmg
+at the root of it. Otherwise, the device will not boot. It is also expected that it
+contains a shell, a ssh server, and various command line utilities.
+.It Fl p , -pongo-shell
+Exit after booting into a clean PongoOS shell
+.It Fl P , -pongo-full
+Like
+.Fl p , -pongo-shell
+but default images and options have been uploaded and applied respectively.
+.It Fl r , -override-ramdisk Ar ramdisk file
+Override the ramdisk. At a very minimum, it should contain
+.Em /cores/ploosh
+as well as a fake dyld
+.Em /usr/lib/dyld
+where the logic is expected to be in.
+.It Fl R , -reboot-device
+Reboot device in normal mode and exit.
+.It Fl s , -safe-mode
+Enter safe mode. An alert will be displayed on iOS/iPadOS/tvOS. Jailbreak daemons nor early boot executable files
+specified (see
+.Sy FILES
+section below) will be executed. The loader app and the built in SSH server can still be used,
+as well as any jailbreak-specific apps you have installed.
+.It Fl S , -no-colors
+Disable colors on the command line. External programs like checkra1n clones may still output colors.
+.It Fl T , -telnetd
+Enable the TELNET daemon on port 46, all interfaces. Please note that there is no authentication and is therefore insecure.
+.It Fl v , -debug-logging
+Enable debug logging. The option may be repeated for extra verbosity.
+.It Fl V , -verbose-boot
+Boots the device in verbose mode, allowing boot logs to be seen.
+.It Fl I , -device-info
+Prints info about device and exits.
+.It Fl -override-libcheckra1nhelper Ar hook dylib
+(Apple platforms only) Specify a custom dylib to insert into checkra1n via
+.Em DYLD_INSERT_LIBRARIES
+\[char46]
+.El
+.Sh ENVIRONMENTAL VARIABLES
+.Bl -tag -width -indent
+.It Ev TMPDIR
+This environmental variable should contain the a directory for temporary
+files. Without the
+.Fl i , -override-checkra1n
+option, files must be executable from it as the built-in checkra1n file
+is extracted and executed here. When not set, /tmp is used.
+.El
+.Sh EXAMPLES
+To (re-)jailbreak in rootless mode:
+.Pp
+.Dl "palera1n -l"
+.Pp
+To setup fakefs for rootful mode:
+.Pp
+.Dl "palera1n -fc"
+.Pp
+After the device has rebooted into recovery mode, follow the following example.
+.Pp
+To re-jailbreak in rootful mode:
+.Pp
+.Dl "palera1n -f"
+.Pp
+To remove the jailbreak in rootful mode:
+.Pp
+.Dl "palera1n --force-revert -f"
+.Pp
+To remove the jailbreak in rootless mode:
+.Pp
+.Dl "palera1n --force-revert"
+.Pp
+To verbose boot in rootful mode:
+.Pp
+.Dl "palera1n -Vf"
+.Pp
+To create a partial fakefs with bind mounts:
+.Pp
+.Dl "palera1n -Bf"
+.Pp
+To exit recovery mode:
+.Pp
+.Dl "palera1n -n"
+.Pp
+.Sh CAVEATS
+.Pp
+.Em -v
+is not a real XNU boot argument. It is interpreted by iBoot. However, since XNU
+boot arguments are set in PongoOS, which is ran after iBoot has ran, it does nothing.
+To verbose boot, use the
+.Fl V , -verbose-boot
+option when jailbreaking.
+.Pp
+Fakefs takes up around 5-10 GB of storage, and takes up to 10 minutes to setup.
+.Pp
+iOS 15.0 requires DER entitlements, and iOS 15.1 requires hash agility in code signatures.
+As a result, binaries with the old code signature format need to be resigned with a recent
+version of the Procursus fork of
+.Xr ldid 1
+before they can be ran on a device jailbroken with
+.Nm
+\[char46]
+.Pp
+When using rootful mode, the
+.Fl f , -fakefs
+flag must be specified at all times. It does not matter whether you want to create fakefs,
+create partial fakefs, rejailbreak or remove jailbreak.
+.Pp
+Due to a stock bug, using the
+.Fl V , -verbose-boot
+option might cause some versions for tvOS to crash and not boot.
+.Pp
+Offical Apple USB-C cables as well as some other USB-C cables cannot be used to enter DFU mode.
+USB-A cable with male USB-C to female USB-A adapter works fine.
+.Sh POST INSTALLATION (iOS/iPadOS)
+The palera1n loader app will take up to 1 minute to appear on the homescreen after the
+device has booted. If it does not appear, you can try using the shortcut:
+.Pp
+.Lk https://www.icloud.com/shortcuts/8cd5f489c8854ee0ab9ee38f2e62f87d
+.Pp
+to open it. After opening the loader app, select a package manager to install.
+This will also bootstrap your device.
+.Pp
+A built-in SSH server runs on port 44 on loopback interfaces.
+.Sh POST INSTALLATION (tvOS)
+.Pp
+The palera1n loader app will appear on homescreen. Open the loader and select a package manager to install.
+This will also bootstrap your device.
+.Pp
+A built-in SSH server runs on port 44 on all interfaces.
+.Sh POST INSTALLATION (bridgeOS)
+.Pp
+A built-in SSH server runs on port 44 on all interfaces.
+.Pp
+Bootstrapping is currently not supported on this device.
+.Sh FILES
+During the jailbreak process, a temporary filesystem is mounted on /cores as a place
+to stash jailbreak files needed during the boot process. No files are ever written
+onto the actual disk if you do not use the SSH server to write files or using the
+loader app to install additional jailbreak files.
+
+.Bl -tag -width "/var/jb/Library/LaunchDaemons"
+.It Pa /cores
+The location of the temporary filesystem where jailbreak files are stashed during boot.
+.It Pa /Library/LaunchDaemons
+The directory where jailbreak-specific
+.Xr launchd.plist 5
+property list files should be placed on rootful.
+.It Pa /var/jb/Library/LaunchDaemons
+The directory where jailbreak-specific
+.Xr launchd.plist 5
+property list files should be placed on rootless.
+.It Pa /etc/rc.d

+.Sh BUGS
+.Nm
+may crash if the machine it is running on has non-compliant USB devices plugged in.
+.Pp
+.Nm
+will fail to initialize on Linux when there are no USB devices plugged in.
+Usually this is not a problem on PCs since the built-in root hubs are also
+USB devices. However, on platforms such as Apple Silicon Macs in Linux, since
+there are no built-in USB hubs, at least one USB device needs to be manually
+plugged in for palera1n to be initialized.
+.Pp
+The exploit may also work less reliably on some hosts, like AMD desktops, or some MediaTek devices.
+.Pp
+The built-in SSH server might be not accessible with password after bootstrapping rootful,
+since the bootstrap uses a custom crypt() function that is not supported
+by the built-in SSH server.
+.Pp
+There are no DFU instructions for iBridge T2 as there are no known ways to connect to the T2's USB
+interface when macOS has been booted.
+.Sh DEPRECATED AND REMOVED FUNCTIONALITY
+There was an option in
+.Nm
+to force create the fakefs even when one already exists (which would overwrite
+the existing fakefs), by setting the palerain_option_setup_rootful_forced flag
+in palera1n flags. This option was removed because using
+.Fl -force-revert
+and
+.Fl c
+at the same time has exactly the same effect.
+.Pp
+The hook that enabled
+.Sy launchctl runstats
+has been removed, since it leaks memory in launchd.
+.Sh SEE ALSO
+.Xr launchd 8
+.Xr launchd.plist 5
+.Xr ldid 1
+.Xr p1ctl 8
+.Sh HISTORY
+The
+.Nm
+jailbreak was first written by Nebula and Mineek on September 26, 2022, as a shell
+script. Tweak support with DEVELOPMENT kernels are added on October 2, 2022. RELEASE
+kernel support is added on November 14, 2022. iOS 16 Support is added on
+December 13, 2022. Later, the first attempt to rewrite palera1n into C begins on January
+01 2023. The
+.Nm
+utility described here is the second attempt, which first started on January 16, 2023,
+using checkra1n 1337 and a custom KPF.
+Something happened on August 15, 2023.

+ palera1n is an iOS/iPadOS 15.0+ semi tethered jailbreak
+ based on the checkm8 exploit.
+ .
+ palera1n is able to jailbreak the device in fakefs-rootful mode,
+ where / is writable, as well as rootless mode, where / cannot be
+ written to.
+ .
+ IMPORTANT: This does NOT make palera1n untethered or allow you to
+ jailbreak your current device without a computer. It just allows
+ you to jailbreak another iDevice using this device, given you have
+ an appropriate cable. Also, the success rate is likely to be bad.
