I am a DIYer on a budget so I bought Xtool D7 as a tool to help me find and fix the problem. This tool leaves no stone unturned and the technology and power behind it is excellent! Try it, you will like it. I would also say that if you are having trouble activating xtool, it may be due to your internet settings regarding your Wi-Fi connection. I had my phone as a hotspot to activate mine.
