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; }
