Info / Instructions

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
