Well, I didn't get any donation these days. And I'm not the guy selling unlock files. You can try to contact the guy.In fact, I made the donation and sent you the file you needed to send me the other 2 files I need for unlocking. Am I wrong something?
But the way, I have mentioned in the tutorial, it's recommended to follow the automatic method. Once you have unlocked your phone, you can get the unlock file by yourself.
