opensn0w is a dead project originally made by me way back when in 2011. Its original purpose was to be an open-source duplicate of redsn0w (that never came to pass). Recently, I took the old source tree I had, fixed it up a bit, removed some old bundles and added iOS 7 support to it.
This thing is a generic tethered booter for all devices that use
steaks4uce. If you have another boot ROM exploit for a newer device, feel free to send in a pull request. ;P
Apparently, it’s hard for people to install this, here’s the instructions for an Ubuntu/Debian system at least. (Please note, this does not work on Mac OS X or Windows yet. Support for those will be done eventually, or if you feel like it, implement it).
$ sudo apt-get install build-essential automake autoconf git libusb-1.0-0-dev libcurl4-openssl-dev \ libreadline-dev $ git clone git://github.com/winocm/opensn0w.git $ cd opensn0w $ sh autogen.sh $ make $ sudo make install
The binaries should be in
/usr/local/opensn0w/bin and bundles in
/usr/local/opensn0w/bundles by default. It’s not too hard. (Install the package equivalents for your system if you’re not running Ubuntu/Debian respectively.)
Usage is simple, specify the
-p flag to specify a bundle property list. The bundle property list should at least have Keys/IVs for each Image3 file along with a relative path. The path for things like
AppleLogo is mainly irrelevant, as that’s cosmetic. Make sure your user can write to
/dev/usb otherwise run opensn0w as root. The
-v option is used to display additional debug output.
$ sudo /usr/local/opensn0w/bin/opensn0w_cli -v -p /usr/local/opensn0w/bundles/iPhone3,1_7.0_11AWhatever.plist
Of course, modify the command line to fit your needs and make sure your device is in DFU mode.
opensn0w.conf file defines both kernel and iBoot patches. Another opensn0w configuration file can be specified using the
-f option. IPSWs can also be selected using the
-i option. If an IPSW is not found, it is downloaded automatically from Apple using the URL provided in the bundle property list.
BootArgs are specified using the configuration file also.
Well, you can put files onto your device using an SSH RAM disk… the rest is up to you, this tool does provide everything you need to bootstrap arbitrary kernels/iBoots and patch them automatically.
(Why did I have to write this?)Share
