Would like to unlock an 810i, explored the forum posts etc but would like some of the terms explained, if possible, I believe it to be 2010 cid49 but have not been able to confirm?,how do I do that, what is gdfs why is it best to back it up and how, what software will I need to unlock, for example what is xs++ I am sure there will be more questions as I get deeper into the concept, many thanks,
