These are utility binaries precompiled on Ubuntu 8.10. They require:

- libncurses
 
- libusb
 
- libreadline
 
 
You may elect to build them from source by pulling from
 
iphonelinux/openiboot's git repository.

BE WARNED THAT THESE STEPS ARE NOT INTENDED FOR NOVICES. YOU ATTEMPT THIS AT
 
YOUR OWN RISK. AT THIS TIME, WE CANNOT AFFORD THE EFFORT REQUIRED TO GIVE
 
SUPPORT TO NOVICES AND/OR RESCUE THEM FROM THEIR OWN ACTIONS.
 
 
Although unlikely, if the installation goes wrong, you may have to perform a
 
DFU restore on your iPhone. If you do not know how to do that, you should not
 
follow these steps. You should also know how to use iRecovery (or similar) and
 
the fsboot command to "kick an iPhone out of recovery mode". If you do not
 
know how to do that, you should not follow these steps.
 
 
The installation of openiboot itself is safe, but openiboot has the facility
 
to erase device-specific information from your NOR flash. If you did not make
 
a backup, and execute the commands necessary to make openiboot erase that
 
information, it is gone forever and your device may never boot properly again.
 
 
The instructions below will show you how to make such a backup before any
 
changes are made.
 
 
== Installing OpeniBoot ==
 
 
1. Put your iPhone in [[Recovery Mode]].
 
 
2. sudo ./loadibec openiboot-2g.img3, or -3g, -ipod, depending on your platform.
 
 
3. sudo ./oibc
 
 
4. nor_read 0x09000000 0x0 1048576
 
 
5. ~norbackup.dump:1048576. This will create a file called norbackup.dump in your current directory. GUARD IT WITH YOUR LIFE.
 
 
6. install
 
 
7. After 'install' has finished, type in: reboot.
 
 
8. You ought to see the openiboot menu.
 
 
== Booting Linux ==
 
 
 
Use the Hold button to navigate the menu. Push the Home button
 
when openiboot client is selected.
 
sudo ./oibc
 
!zImage
 
kernel
 
!rootfs.arm.ext2.gz
 
ramdisk 3588
 
boot "console=tty console=ttyUSB root=/dev/ram0 rw"
 
sudo ./linux
 
 
You should now get a login prompt. Nothing that's happening will show up on
 
the LCD automatically, but you can redirect it to the display with the
 
following command:
 
 
sh 2>&1 > /dev/tty0
 
 
Enjoy!

Device running the OpeniBoot console.

iDroid is a project with goals of porting Linux and Android to iPhone, iPod touch and iPad and use different OSes as alternatives to standard iOS.

iDroid is not actually a hack/exploit neither an unlock, but it is based on Bootrom exploits which allowing the running of unsigned code at low level.

OpeniBoot

The goals of OpeniBoot are:

  • to run low-level code
  • to have low and critical drivers (NAND and NOR driver, NVRAM...).
  • to have a debugger and development environment (chainloading, upgrading itself and USB mass storage).

Linux

A Linux Bootloader, a working Linux kernel (cross-compiler), porting drivers, run Wi-Fi and command line through SSH.

Android

On 21 April 2010, an Android distribution based on iPhoneLinux called iDroid was released.
