Open-source jailbreaking tool for many iOS devices

About this fork
This fork allows you to load img4 images (e.g. iBSS/LLB) in pwned DFU mode.
Also supports loading of unsigned img4 images. Run "python rmsigchks.py" to remove signature checks.
Supports s5l8960x (iPhone 5s) and - new - t8011 (iPad Pro 2017).
IMPORTANT: Other devices are currently NOT SUPPORTED.
permanent unpatchable bootrom exploit for hundreds of millions of iOS devices
meant for researchers, this is not a jailbreak with Cydia yet
allows dumping SecureROM, decrypting keybags for iOS firmware, and demoting device for JTAG
current SoC support: s5l8947x, s5l8950x, s5l8955x, s5l8960x, t8002, t8004, t8010, t8011, t8015
future SoC support: s5l8940x, s5l8942x, s5l8945x, s5l8747x, t7000, t7001, s7002, s8000, s8001, s8003, t8012
full jailbreak with Cydia on latest iOS version is possible, but requires additional work
Quick start guide for checkm8
Use a cable to connect device to your Mac. Hold buttons as needed to enter DFU Mode.
./ipwndfu -pto exploit the device. Repeat the process if it fails, it is not reliable.
./ipwndfu --dump-romto get a dump of SecureROM.
./ipwndfu --decrypt-gid KEYBAGto decrypt a keybag.
./ipwndfu --demoteto demote device and enable JTAG.
Jailbreak and downgrade iPhone 3GS (new bootrom) with alloc8 untethered bootrom exploit. :-)
Pwned DFU Mode with steaks4uce exploit for S5L8720 devices.
Pwned DFU Mode with limera1n exploit for S5L8920/S5L8922 devices.
Pwned DFU Mode with SHAtter exploit for S5L8930 devices.
Dump SecureROM on S5L8920/S5L8922/S5L8930 devices.
Dump NOR on S5L8920 devices.
Flash NOR on S5L8920 devices.
Encrypt or decrypt hex data on a connected device in pwned DFU Mode using its GID or UID key.
This tool should be compatible with Mac and Linux. It won't work in a virtual machine.
If you are using Linux: install libusb using your package manager.
- iPhone 3GS iOS 4.3.5 iBSS
This tool can be used to downgrade or jailbreak iPhone 3GS (new bootrom) without SHSH blobs, as documented in JAILBREAK-GUIDE.
Write-up for alloc8 exploit can be found here:
Download iPhone 3GS iOS 4.3.5 IPSW from Apple:
In Terminal, extract iBSS using the following command, then move the file to ipwndfu folder:
unzip -p iPhone2,1_4.3.5_8L1_Restore.ipsw Firmware/dfu/iBSS.n88ap.RELEASE.dfu > n88ap-iBSS-4.3.5.img3
Reorganize and refactor code.
Easier setup: download iBSS automatically using partial zip.
Dump SecureROM on S5L8720 devices.
Install custom boot logos on devices jailbroken with 24Kpwn and alloc8.
Enable verbose boot on devices jailbroken with 24Kpwn and alloc8.
This is BETA software.
Backup your data.
This tool is currently in beta and could potentially brick your device. It will attempt to save a copy of data in NOR to nor-backups folder before flashing new data to NOR, and it will attempt to not overwrite critical data in NOR which your device requires to function. If something goes wrong, hopefully you will be able to restore to latest IPSW in iTunes and bring your device back to life, or use nor-backups to restore NOR to the original state, but I cannot provide any guarantees.

You will not need to use
make or compile anything to use ipwndfu. However, if you wish to make changes to assembly code in
