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 4G, iPad, AppleTV 2)
It's possible to extend the compatibility to older devices as well (iPhone 3GS, iPod 3G) by changing:
- the offset to the call of usb_wait_for_image in payload.S
0x7ef @ A4 0x30E9 @ iPod 2G, old bootrom 0x30F1 @ iPod 2G, new bootrom 0x8b7 @ iPod 3G, iPhone 3Gs new bootrom
- exploit offsets in bdu.c
