DFU 0x1227 is the protocol used to talk to a device in DFU Mode or WTF v2.

Protocol

The protocol is the same as sending a file to a device in Recovery Mode on 2.x.

Code

  uint8_t fbuf[FBUF_LENGTH];
  uint8_t buf[100];
  hexdump(fbuf, usb_control_msg(idev, 0x80, 6, 0x200, 0, fbuf, 0x100, 1000));
  printf("WTF: ");
  fgets(buf, 100, stdin);
  buf[strlen(buf) - 1] = 0;
  FILE *f = fopen(buf, "rb");
  int s;
  int c = 0;
  if (f > 0) {
    do {
      s = fread(fbuf, 1, 0x800, f);
      if (usb_control_msg(idev, 0x21, 1, c, 0, fbuf, s, 1000) == s)
        printf(".");
      else
        printf("x");
      if (usb_control_msg(idev, 0xA1, 3, 0, 0, fbuf, 6, 1000) !=  6|| fbuf[4] != 5)
        printf("%d", fbuf[4]);
      c++;
    } while (s > 0);
    printf("\n");
    usb_control_msg(idev, 0xA1, 3, 0, 0, buf, 6, 1000);
    hexdump(buf, 6);
    usb_control_msg(idev, 0xA1, 3, 0, 0, buf, 6, 1000);
    hexdump(buf, 6);
    usb_reset(idev);
    fclose(f);
  } else {
    printf("file not found\n");
  }
  system("PAUSE");
  return 0;
}
