Info / Instructions
- you need a mac or linux box to use it / build it
- libusb 1.0.8 required
- execute it with root privileges (sudo ./bdu)
- by default compatible only with A4 devices: (iPhone 4, iPod touch (4th generation), iPad, Apple TV (2nd generation))
It's possible to extend the compatibility to older devices as well (iPhone 3GS, iPod (3rd generation)) by changing:
- the offset to the call of usb_wait_for_image in payload.S
0x7ef @ A4 devices: iPad, iPhone 4, Apple TV (2nd generation), iPod touch (4th generation) 0x8b7 @ iPod touch (3rd generation) 0x8b7 @ iPhone 3GS new bootrom 0x8b7 @ iPhone 3GS old bootrom 0x82c @ iPod touch (2nd generation) new bootrom 0x82d @ iPod touch (2nd generation) old bootrom
- exploit offsets in bdu.c
