Please try to use our latest software from here - https://www.dc-unlocker.com/downloads/get/H0TOCp3w let us know if you still get same error code. There shouldnt be other modems or phones connected to pc at unlock time. Also try to unlock device while there is a sim (card that does not work with your device) inside and when there isn't one.
