ipwndfu: open-source jailbreaking tool for older iOS devices

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.

No warranty

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

Dependencies

This tool should be compatible with Mac and Linux, and it was mostly tested on Yosemite and Sierra. It probably won't work in a virtual machine.

libusb

On a Mac, you can install libusb using brew:

brew install libusb

pyusb

On a Mac, you can install pyusb using pip:

pip install pyusb

On a Mac, if you do not have pip installed, follow instructions from the official site and install it with get-pip.py: https://pip.pypa.io/en/stable/installing/

iPhone 3GS iOS 4.3.5 iBSS

Download iPhone 3GS iOS 4.3.5 IPSW using a link found on https://ipsw.me/ and 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

Patch for libusb required to make limera1n work on El Capitan and Sierra

Reason:

https://www.belle-aurore.com/mike/2016/06/os-x-el-capitan-and-its-refusal-to-reset-usb-devices/

You should have libusb installed using brew. 1.0.21 is the latest version. Calculate the SHA1 hash:

openssl sha1 /usr/local/Cellar/libusb/1.0.21/lib/libusb-1.0.0.dylib

Currently supported hashes (original -> patched):

libusb 1.0.21 on Sierra
02da61201c8f67b723bca5fb44b35797d1021625 -> f356ee6052cd520b46ca50333b937ff2efe4477b

Available patches are in libusb-patches folder. Apply the patch matching your SHA1 hash using bspatch:

sudo bspatch /usr/local/Cellar/libusb/1.0.21/lib/libusb-1.0.0.dylib /usr/local/Cellar/libusb/1.0.21/lib/libusb-1.0.0.dylib libusb-02da61201c8f67b723bca5fb44b35797d1021625.patch
