I am scared about the fact that so many youtubers, hardware tech foren and so on make news about this "unlocker" and do no own research. They give him a lot of range with it for his scam, and that they don´t delete this wrong news.
Dont know why so many youtubers and other people making this so big , i guess the most of them doing it because they maybe get some clicks on there channels.
And i just have seen a new Video from the same youtuber that OP has posted on the first post in here , and its looking like its confirmed that this LHR-Unlocker is a Scam.
The Video was uploaded today and here is the Link :
