How to restore original level?

Hello guys,
I couldn't find a solution for my problem but if anybody already posted this kind of request just give me a link and close this topic.

Well, I've just finished a match and to my suprise I have been promoted to 70 rank... The problem is I really don't want it. And here is my question, is there any way to restore my original level? I remember that on one forum somebody posted a special command to write in console but I can't find it now... Some people also claim that one can use .bak files from game folder. But I couldn't find any 100% working solution. Do u have any idea how can I recover from 70 lvl hack? THX in advance.

You havent searched this forum at all then, use the search function mate, there is already a guide out for how you reset your level to 1, and many trainers here can do it aswell. You can also use me and Tobii's trainer which can also lower your level, and all other stats. PM me if you experience any problems or need more help
