Recovery Mode 0x1281

This is the new Recovery Mode protocol used in 2.0 iBoots.

Commands
usb_control_msg(idev, 0xA1, 3, 0, 0, buf, 6, 1000); //get status usb_control_msg(idev, 0x40, 0, 0, 0, buf, strlen(buf), 1000); //send command usb_control_msg(idev, 0x21, 1, 0, 0, fbuf, s, 1000); //write memory

It also has another interface which appears like a USB to serial converter.
